800 WHP TURBO TAHOE BUILD LET'S TALK TECH

Added: 2026-05-07

[00:00:06]Yeah, we're we are live. It's 7:33.

[00:00:09]How's everybody doing tonight? We I just got back from uh from snaking. Got got got four today. So, it was good. It was a good snake day. Even though it's it's very overcast. A lot of people think that on the snakes that they think it needs to be really hot to go out and catch snakes. That's that's the opposite of what's true. I find that I find the most snakes 65 to 70 degree degree weather. They they like that. They have to thermorreulate. So you'll find them under things. Sometimes you can find them out when and sunning themselves, but they're not going to do that when it's 90 or 100°. They're going to go hide because they get too hot and they'll actually they can actually pass away if they if it gets too hot for them. So the these kinds of temperatures are really good even though it's overcast.

[00:00:52]But tonight we want to talk about the Turbo Tahoe.

[00:00:56]And this is because I just got I get an onslaught of questions about it and people want to know, hey, what what is this? What is this? What is this? What did you do to this? What you know, all these things. And so it made me think that, hey, look, I should just do a video, you know, the 10 or 15 minute videos where we just cover everything that went into it. So what did you do?

[00:01:17]What did you know what h what is the motor combination? What are the important? I mean, it's basically a stock 53 with a cam in it, but there are other things. It has the RHP springs. It has the RHP um, you know, pump and injectors and obviously our turbo and our prototype turbo kit. And so, so when you start listing off all these things, then people, you know, a lot of these things are important to people. So, they want to know what what combination that you put together to do these things.

[00:01:45]made 800 at the tire and there's certainly more left in that in that G42 if you wanted to do that. We just ran out of fuel with the combination of thousand cc injectors and that 53 and that single 535 pump. We're going to we're going to address that and make more power than that and it certainly can. We know that a 53 will go way beyond that.

[00:02:05]Whether or not the other things will that's that's always a question. In fact, we found that out today in the S2000. Jimmy is running the the RHP uh 1000 turbo, the the G35 turbo, and he's running that on the S2000. Now, it's a modified motor, and I'm going to I'm going to make a post tomorrow about this, and so we'll we'll go over all of the important specs, mods, for pistons, you know, cams, yada yada yada, all that stuff. Brian Crower has good stuff in there, which I they they do good stuff over there, Brian Crower. Um, but Jimmy, we had already I'd made a post where we had made well, he had made 700 plus horsepower, and that thing has gone to 800 before, but he stepped his game up today. That with that single turbo, with that G35 turbo, it made 960 at the tire.

[00:02:55]So, we know that that turbo can support 1,000 horsepower because it just almost got there at the tire. So, it certainly is that at the flywheel, and that's where these these turbos are all rated at the flywheel. And it brings up another important discussion that we probably should have on another day on a live feed. But these numbers that the manufacturers give you, whether it's Borg Warner or Garrett or Force Performance, Robert over there, VS Racing, our turbos, all all of these maximum numbers are just that. They're maximum numbers. PE people get confused and and excited and think that that that's where they should run it. Oh, I'll run that one up to eight, you know, the the RV 800, the 3584 uh RS, the GTX turbo. But 800 is not a good place to run that turbo if you're going to run that if you want to run make that much power. Yeah, it will just like this. We know this G35 on this. It's a little bit bigger than 2 liters, but you know, a K series Honda is an ideal place to run a turbo because they're so good naturally aspirated and it's small enough to where you can really make a lot of power with the turbo and not have to worry about running out of hot side, but it allows you to get to the maximum of both of those basically. And we're monitoring back pressure on that. And so he turned the boost up to I don't know was a good bit over 30 pounds. And um so it made a lot of power and we're doing it because we want to monitor all of that data and find out we want to be able to correlate different back pressure and boost pressure relationships on different displacement motors and at different power outputs and stuff because we see you know it's interesting if you really get in there and do the data logging on this that you see a changing boost pressure to back pressure relationship as we go up in boost. And you and you would kind of expect that now on a 2 liter or 2.2 or 2.3 liter motor with a 1000 horsepower turbo. Jimmy and I were talking about this today. I'm like, well, you're not going to see a lot of back pressure on that because again, this is a really good motor and it's small enough that it makes a lot of power and it makes a lot of power under boost. So, it's like the ideal thing for this kind of combination. You're not going to try to get a thousand horsepower out of that on a four liter, a 5 liter, a six liter turbo. I mean, a six liter motor. It's just not going to do it. And so that all of that stuff is very important, but we wanna we want to have all the information that we can and tell people, hey, look, if you run this because one of the things that we we laugh about is when when you go look up a turbo, particularly online, a lot of the offshore stuff or whatever, but but even even the bigname guys, they'll they'll list the turbo, this turbo will make this amount of power and it's good from this displacement to this displacement. I'm like, yeah, but both of those things are not true. It It's not going to make that maximum power level at the biggest motor displacement size that you're listing there. It can't. It certainly can do that like we did. Like if you if you say it works on a, you know, a 2 liter to a seven liter.

[00:06:07]That's a pretty big range. That's a big spread. It's not going to do the same thing on a seven liter than it does on a 2 liter because you're going to run out of hot tide flow. You're going to have a lot more back pressure on the 2 liter.

[00:06:18]you're going to look like a hero on a seven liter. It's going to be much much less. And that's why we rate the turbos even though like our the the Rip 800 turbo, we rate it at 800. It actually is rated at 950 or certainly over 900, but it's not going to do that on the LS applications. that will do that like on Jimmy's motor or on the NSX or RB or 2J or the JDM guys on on any of those a B16 a B18 a D series whatever whatever you want an EVO motor.

[00:06:51]So if you want to run it on one of those, you you you know, good things can happen. But we want to show what the difference is and what effect the boost pressure to back pressure relationship, what effect um displacement has on that and even varying power levels like a stock 48, a modified 48, a stock 53, all of that stuff so that we can, you know, when people ask us the questions about these things, we can make informed decisions and give them the information that they need. It's good stuff. So again, that's a big number for for that G35. And you know, my hats off to Jimmy, the unfortunately, just like with the 4060 in the in the Tahoe, the stock transmission did not like that. And the clutch is fine, but the transmission is not fine. So, he's going to be putting another transmission in there. And then we're going to be doing more turbo testing and and we'll do the the smaller turbos. And we have another turbo that we're going to try. a super secret custom one. And then Jimmy's also got I think gonna run the the G42 on there, which could certainly could make more power than the than the G35, but that G35 that's pretty impressive. That's a lot of power. You know, 900 plus. I mean, 950 plus um at the tire is a is a lot of power. And so that, you know, that G35, the RIP 1000 doing some work on those. So if you if you have a JDM motor and you want to make lots of power and we're also obviously logging all of the all of the response rates and stuff because that again all that's just really good information and it's stuff that everybody needs and it's it's stuff that they need to be able to make an informed decision on what they want to choose like do I want that and and even Jimmy's like yeah that's a great turbo it makes a lot of power I'm probably never gonna run it there not that car with that much power is particularly driving on the street. He said it's just going to be it'll just be useless. He said, you know, at 600 at the tire, it's going to be more than more than you probably would want, but it'll be fun.

[00:08:56]And so then you decide, okay, I don't need that extra 300 at the tire or 350 or whatever. I don't need that. So what that does, that brings other turbos, smaller turbos into play so that you get more response. But do you want that? Do you want the boost coming on at 2500 or 3500 or whatever the number is? Do you want that?

[00:09:20]Those are all decisions that you have to make. And um it's important to understand that people don't you don't you can't have all of that. You can't have, you know, off idle boost and and you know a thousand horsepower. So that's it's hard hard combination to come across.

[00:09:37]But again, lots of cool testing and so I'm I'm excited about seeing more data on on more of the turbos once he he's got put another transmission in there.

[00:09:46]But good stuff and I'm going to I'm going to post some stuff on that with the with the power curves and stuff at the different boost levels. That will go up tomorrow on Facebook and Instagram.

[00:09:53]So if you you guys can check that out.

[00:09:57]So let's see what you guys got going on for tonight. Uh I bought another Lincoln. There you go. What what year Lincoln and what model and all that?

[00:10:04]Prestige jet. What's going on? Oh. Oh, I should have looked down. I'm just reading them one at a time. 04 Aviator.

[00:10:13]Those are good. I like those motors.

[00:10:14]160,000. Electrical issues mechanically.

[00:10:16]All right.

[00:10:19]I need that aluminum 464 valve in my life. I agree. Those are good. And and kind of a unique intake manifold on those, which I like. I like the unique um intake manifold. Dual runners or long runners like the um the Navigators like that. They're just cool stuff.

[00:10:37]Pubmaster, what's going on? Made it.

[00:10:39]Made it. What should I do to the Aviator hot rod wise? I'm already got to drop my 98 Cobra intake cams in. Okay.

[00:10:50]Um I I think that if I remember right, I think that the Cobra manifold made more power than the Aviator one did, too.

[00:10:57]Awesome podcast with Bugghetti. So, you guys you did you did watch that. That's good. We had we talked last night and we had a poll on whether or not people were going to watch it. Um, I I thought it turned out good.

[00:11:10]I want it to stay readily daily drivable. Don't want to change the intake. So, a PD blower is out unless I adapt it. Well, you know, you can get a turbo and and modular motors has, as John Mohovitz and other guys have shown, that modular motors definitely love turbos. And I've run lots of turbos on mod motors. Scottish, what's going on?

[00:11:27]Could you compare methanol injection versus ammonia injection on the dyno?

[00:11:32]What what do you think we we would see there? Is is ammonia even is it even flammable?

[00:11:41]Thinking 500 to 600 wheel range would be excellent with all-wheel drive will embarrass most factory vehicles but won't take huge amounts of work. Yeah.

[00:11:50]Will the will the all-wheel drive setup on that will it take that kind of power?

[00:11:57]Any tricks for bell housing bolts and flex plate bolts? That's all I have left. Then installing the 4080.

[00:12:07]Um, we always use factory bell housing bolts and on the flex plate bolts or the fly we we normally put flywheel on stuff when we're when we're doing stuff on the engine dyno, but ARP has flex plate bolts, too. They're they're just they're not as long as the flywheel bolts.

[00:12:26]Easier to make all the drivetrain parts live behind 600 and 800. Oh, yeah.

[00:12:29]That's definitely That's definitely Sure. There's no trick besides lots of U-jints and extensions and maybe Oh. Oh.

[00:12:35]to get to those maybe. Isn't that's what you're talking about?

[00:12:40]I thought you were talking about putting them together and not taking them apart.

[00:12:44]Yeah, it's definitely lots and lots of long extensions and wobblies.

[00:12:50]So, always wanted to put a PD blower on an AV Aviator lower. The Aviator makes more average power than the Cobra manifold when the Emerick is active.

[00:13:01]Will a 112 make 600 without winding it to the moon?

[00:13:08]It will make 600 flywheel, but you will have to spin it though.

[00:13:15]It's reading about ammonia again. It's about 130 octane. Takes 27 to1 compression to ignite via compression.

[00:13:22]Seems interesting. It it it is flammable though. Ammonia is Richard. On pump gas and twin 770s with keeping the 317s, will 800 wheel horsepower be possible or keep safe? I don't know about the power levels on pump gas. I don't I don't really have a feel for that.

[00:13:41]I'm running a built 54 MMR in my 90 Fox body. Nice. It loves to kill tires unless you're rolling at 100.

[00:13:50]Is it a turbo motor then? Or a blower motor? What is it?

[00:13:55]on the 54 and is it a four valve or a two valve? I love the questions here. It makes me think about things I've never thought of and opens up a whole new rabbit hole. It does there. That's why there's a lot of good, you know, there's a lot of good questions that come on these live feeds and and even stuff that not I mean when I obviously we were talking about the the Tahoe and stuff initially and then the the G35 Turbo that Jimmy did on the S2000 which those are those are opposite ends of the spectrum. But after that, people bring in all kinds of stuff.

[00:14:30]I know the diffs and the axles will take 800ish as well as the trans with some work. The transfer case is a question mark. Yeah, that's the thing I was wondering about. And and as you put more and more power to the all-wheel drive stuff, especially if it hooks up, it becomes more problematic.

[00:14:46]Are the Richard Junior cams coming back in stock? No. So the um the ripper juniors are not I had a snag. It's usually done when the main bearing thrust surfaces are too wide to fit into the thrust crankshaft journal.

[00:15:05]Is the bearing wrong or is the is the crank surface wrong?

[00:15:21]would really like to see a 93 octane.

[00:15:28]Try it. Seems like 93 octane 53 is where it's at. Yeah, you just have to turn the timing down.

[00:15:39]What's a source for a bigger blower than a 122 with a passenger side throttle body?

[00:15:50]With a passenger side throttle body?

[00:15:53]I don't know. Are you going to have to make that?

[00:15:58]These lives are the best. One of the greatest learning experiences. Good. I'm glad you like it. Should I just go for a Cobra 1.9 Kenny Bell or swimmer to adapt onto?

[00:16:07]I I think I would pick something bigger than a one nine.

[00:16:13]Ammonia. Might as well stick with something safe like hydroine.

[00:16:18]I was wondering. I don't I I've never tried ammonia. I mean, I've cleaned windows with it. Discus couplers saved many allhe drive systems.

[00:16:32]What was the fuel system you were running with the setup and what type of fuel on? Which one are you talking about? On the um on the Tahoe it is,000 cc injectors and our 535 pump.

[00:16:47]On S2000 it is um let's see what size Jimmy told me what size the injectors are.

[00:16:58]Uh it is our 22 2200cc injectors and we have two 525 pumps um on the S2000.

[00:17:15]The Aviator does has have a viscous coupling the transfer case. Is it normal to have lifter on an L99 after installing a BTR stage 2 kit? cam lifter springs, standard length push rod, and head gaskets all at their recommendation. I don't It shouldn't make noise.

[00:17:33]There shouldn't be lifter noise. The hydraulic lifter has preload on it, so that shouldn't be making noise.

[00:17:41]Richard, can I drive my RHP built zenali out to California to come see you when she's done? Let's design an awesome RHP lowbuck wrap.

[00:17:53]Where are you at? Would would it be better to have you drive it to Georgia?

[00:18:00]I have 50 pounds of oil pressure at idle. That's good.

[00:18:04]I meant the Tahoe. And I'm assuming that the single 525 pump was good because it wasn't E85. No, it was E85. We made 800 wheel horsepower on E85 with a 535 pump and the 1000cc injectors because that's what we were running to make that power level because it because we ran 18 and a half pounds of boost to to get to 800 wheel horsepower. It's 815, but that's atund 101% duty cycle.

[00:18:33]So that's all of it.

[00:18:35]Crank surface looks fine. It's just like the new thrust main bearing was made too wide to fit. The old bearings are all stamped standard and so are the new ones.

[00:18:49]Does it not go on or does it go on and it's loose? Like what what is the fitment issue?

[00:18:55]LS4.8 with bolt-ons and 410 gears. Does a truck plus cam require bigger converter? Yes, on a 48 I would put a converter in it. on a 48.

[00:19:06]>> Oh, Arizona. Okay. So, you're you're close to and you want to do a wrap on your truck or something? I I want to do a wrap on my truck because we want we want to put the RHP stuff on it, but unfortunately my paint isn't good enough for a wrap to stick to it. Probably crank surface looks fine.

[00:19:28]You in Georgia or California? I'm in California, but um Jimmy is in Georgia.

[00:19:36]BTRS says lifter noise is common because of a smaller can base and to try heavier oil, but made no difference. It's just a few lifters, but it's annoying. That's interesting.

[00:19:50]What do you think about learning how to tune on an LS? Do Are you asking me what I think about you learning to tune it? I think it's a good idea.

[00:20:01]I'm in the same boat. Got the good old Chevy Sunfade on the clear coat. Yeah.

[00:20:06]All of my The guy I bought bought it from did a quickie paint job on it, I'm sure, to sell it and and it worked because it looked good. It was red. It was bright red and that's what I like and that's my jams. And it was shiny and it looked good and it just didn't last very long. It's all peeling off now. And now unfortunately to peel it off, you know, you got to take all of it off. And I would love to just wrap the whole truck and not have to worry about that, but it's not even a in a position to do that.

[00:20:38]And I'm not not motivated enough to sand the whole thing, which is what I think would have to happen. Maybe I just need to have a I need to have I need to have a sanding party, right? Just It's like a moving party.

[00:20:54]Yeah. the the top um the roof horrible. The the hood horrible.

[00:21:01]The some of the doors are okay. The some of the sides though where stuff is peeling off. It's not good.

[00:21:12]So, I don't think I'll be learning much about body repair or paint in school.

[00:21:14]I'm curious to see what I can learn these things. Yeah, it's not it's not terribly hard. You can get to a fairly decent level pretty quick by doing stuff, you know, sanding and bondo and stuff. It's good to have a guy there to show you, but if you want want to get to a really high level of making the thing like perfect, that dol, you know who's good? Doulich is really good at that stuff.

[00:21:39]I have a 2014 Camaro 1LE. I was thinking of getting HP Academy and learn how to tune. That's good. Also, there's lots of stuff online, lots of sources online like um Goat Rope Garage, the the HP Academy stuff is good. Um you could you could learn it, but you got and you got to learn by doing it.

[00:21:59]Painted a new fender for my Lexus in the backyard. I'm painting clear coat off of Amazon. Girlfriend was beyond skeptical, but really impressed when it was finished. Nice. It's all about the prep.

[00:22:11]Getting ready to finish my 48 Gen 3 to 60 Gen 4 swap with a truck plus cam. How would I go about tuning it to be able to drive it around safely to break it in before it gets professionally tuned? It It more than likely will drive around. I mean, it might stall at idle and that's a thing, but you're you're not going to hurt it.

[00:22:33]Um, and in a six liter, that cam is going to be more idle friendly than it is in a 48.

[00:22:42]I just ordered two RIP 800s. Nice. For my LY6 BTR stage 33 cam going in a fourth gen Camaro. Any recommendations?

[00:22:51]Um, yeah.

[00:22:53]Are like how much power are you trying to make? Because that combination is a lot of power.

[00:23:01]Lots of YouTube channels to learn from because those turbos, like I said, are not rated at 800. They're actually rated over 900. And the reason that we rate it at 800 is because when you're putting it on a V8, it's not going to get to where its maximum is. It's only going to do that on a smaller motor. But when you put two of them there, you've cut the displacement of your V8 in half, an LY6.

[00:23:24]So now you have you're feeding each turbo with a 3 L and it's going to make a lot more power with a 3 liter. So it has a lot more potential. So you have 1600 plus horsepower worth of turbos there. Is that what you wanted to do?

[00:23:40]One of these days I'm going to do my fulltime diff base case I want to build.

[00:23:46]How well do you think I Ford 8.8 diff would live in a transfer case?

[00:23:52]Um, you're not and this is an automatic equipped vehicle, so you're not shock loading the thing, right? I think it might work.

[00:24:03]Shooting for 1,200 wheel horsepower.

[00:24:05]Okay. So, you're you're you're wanting lots of power. Okay. So, that'll be fine.

[00:24:12]I don't know what the rest of the combination is. The cam seems maybe a little big, but it'll work. I want to design it to where you can use it without a gear reduction or install gear reduction box.

[00:24:25]Okay. Can't wait till turbo kits out.

[00:24:27]It's awesome. It'll be compatible with the factory AC. Yeah, the Tahoe has the factory AC still in position and stuff.

[00:24:34]Not going to give it up in Arizona. I don't blame you. And it gets hot where Jimmy is in Georgia, too. And in Southern California and in here in Northern California, all of that, too.

[00:24:42]You know, I I don't want a car without AC anymore.

[00:24:46]Even when it gets to be 70 or 75, you go get in your car or your truck, it's hot in there.

[00:24:53]sure I'm doing. Oh, and I wanted to let people know the Summit um transmission we're using, the 4080 is a part number 700477 and the converter is a part number 700347.

[00:25:08]Um I can put that down.

[00:25:13]Summit 4 AD 700 477 converter.

[00:25:37]Summit Converter 700 347 and it's a 2600 to 2800 stall.

[00:25:57]I wanted to I could we could have selected whatever we wanted, but I wanted to make it like the ones that I normally recommend for this kind of stuff.

[00:26:14]How did you mount the True Cool Transcooler? I'm having a pain finding mounting points and where the hell is the intercooler going to go on our kit on Jimmy's truck. I'll show you photos of it. Um I'll try to post some and in fact maybe I'll post that tomorrow or something when we do the live feed. both the transcooler, it's an external one, not the one in the radiator. We didn't do that. Jimmy put a big one on it. That and use the same cooler for the intercooler. Um the uh secondary heat exchanger for the intercooler is that same thing. They're mounted side by side up front with a crossbar right in front of the radiator. And his is an05 and it works good. There's there's minor trimming as there is in everything. Um, but it works good.

[00:27:06]What do you think the low-end power loss of square ports on a six liter would be compared to 706 heads? It would be noticeable during daily driving. Would it be worth it with a smaller low truck cam? Yes, you will definitely notice it, especially compared to a 706 head. It's going to be a lot below 4,000.

[00:27:21]Um, but it's going to be a lot more power above that, but you don't have a big enough cam. Um, again, it's it's all about the trade-off. It's all about the sacrifice.

[00:27:42]Oh, here I forgot a couple of them.

[00:27:50]Okay, Richard doing the four lady swap.

[00:27:52]Doing the long tube truck plus cam. What do I need to be looking out for with my tuner? Fuel trims and timing of course.

[00:27:58]How do I know what she likes without a dyno?

[00:28:02]Well, you can tune it on the street and you'll know because if it's if you're running at NA, you're going to be looking for air fuel in in the twelves.

[00:28:13]And the most timing that you would ever want to run is 29 degrees. But my guess on pump gas is you're not going to be able to get there at full temperature at 190 or 200 degrees temperature.

[00:28:26]So, at wide open throttle, you're going to be running less than that. Probably 24 or 25 degrees, my guess is.

[00:28:33]Got the garage playlist in mind. Yeah, they have good stuff. Can I reach 600 horsepower on a six liter iron block with wreckport heads on pump gas? You can with boost, but not NA.

[00:28:44]Well, I take the back. You can NA, but it takes a lot of expensive stuff to do that. Takes a really big cam shaft.

[00:28:52]And all all of our NA stuff that we ran is on pump gas.

[00:29:01]Scrolling, scrolling, scrolling.

[00:29:04]What was the drive shaft situation for the 4080 custom drive shaft or modified original? Uh I think I have to ask Jimmy. Um, I know that the um, yolks and stuff were different, but I don't know if they started off with the original drive shaft or not, or if he just got a completely different one. I'll have to ask him on that.

[00:29:26]Since speed differences should be rare, the pinion should be fine.

[00:29:31]Similar to the one Pete Harrell is using for his LS swap 4Runner, uh, three spline 8.8 28 diffs usually end up breaking axle shafts or bending the housing.

[00:29:48]Watch all the Greg Banish podcast. Bill is saying so that must be a tuner, right? Do you have any opinions on dice converters out in West Hills? I don't know. I've never heard of them, so I don't have any opinion.

[00:30:03]Not so sure about using spider gears.

[00:30:05]Spin twice as fast if you hold one side.

[00:30:12]We should lobby to require transmission coolers be separate units from the factory. Yeah, that seems to be a go-to thing for guys is the bigger cooler and one that's outside and and I I would rather have the cooler outside the radiator anyway because I think that that helps with radiator cooling.

[00:30:31]Did anything fail that was unexpected?

[00:30:33]Looking at doing something similar. Did Did anything fail on what, Billy Bob?

[00:30:39]on the 480.

[00:30:42]Looking for a center differential or something else. Yeah, all fulltime cases will die if you do a burnout on one axle long enough.

[00:31:05]How much gain should I expect going from a stock 6 liter to 408 stroker? You It depends on what your specific power output is on the six liter and then what you're doing to the 408. That's easy math. You're you're going from 364 cubic inches to 408 cubic inches. If you came keep the same specific output, that's just math.

[00:31:27]So take your specific output at 364 in and then you multiply it by the 408 and then you get your you get your new power level.

[00:31:37]That's pretty easy. That's that's assuming that you retain the same specific output, which is harder to do when you go up in displacement because usually you have to put a bigger cam shaft in there because the displacement tends to tame the cam down.

[00:31:55]ideas on how not to seem so stinky in traffic despite 15 to1 air. So why why would it smell then if it's um if it's 15 to one? I mean you could put cats in it. You could put high flow cats in it.

[00:32:13]How was the trip to Florida? It was great. Um it was very very short though.

[00:32:17]We, Jimmy and I flew there and we went to see Cooper and we were going to spend the night there, but once we got done with the interview, there was enough time for us to just go back to the airport and fly back to Jimmy's place that same day. So, I didn't get to go out and look for snakes and try to catch an alligator or anything fun.

[00:32:40]But, I I had never met Cooper and so he seems cool.

[00:32:48]Jimmy has full-time job swapping trans, econ, and the car. How much horsepower can a 475 transmission handle? Does anybody know? Does anybody have an answer for that on the build overall talking about shakedown results?

[00:33:10]Um, nothing has happened so far. There there were some things to get through on the two 48 ladies that we have are a different output shaft and so they needed a different depth um uh input shaft I guess. Well, not a shaft but um the yolk and the input on the um on the drive shaft. And so that needed to be different. So that was something that he found out when we were trying both transmissions. Um, the differential was broke, but it was broke before we put the 4080 in it. And so, uh, Jimmy put a different, um, uh, PY unit in that because the spider gears were bad.

[00:33:57]Want to CNC a case to take a common diff like an 8.8 475s. Dan is giving thumbs up on the 475s.

[00:34:10]Thoughts on a GPI cam kit? I I they they know how to make power at GPI, so they make good stuff.

[00:34:20]KFR is perfect under throttle. Chevy 33 calver converters are not your enemy.

[00:34:26]Yeah, high flow cats are not going to hurt power.

[00:34:32]For 1000 horsepower, you recommend porting and machining the 317s.

[00:34:37]It's not necessary. You can get there without it.

[00:34:42]Since the was an '05, that would mean it had a returnless fuel system. Yeah.

[00:34:49]Was that at all a hindrance to making power? No, it has the stock fuel system on it. It has the stock rail, the stock lines, stock everything. Just bigger injectors and just pump.

[00:35:02]We're We're now changing that. Jimmy's probably gonna go to if we want to go to, you know, fourdigit power level, Jimmy's gonna do a we're going to put two of our pumps in it. We're going to put a um a surge tank, two of those pumps, and he's probably going to go to a return style system, but that wasn't necessary at this power level.

[00:35:37]Richard, I was just wondering if the rod bolts in the early 9798 LS1s are going to be an issue at 6,500 to 7,000. I know they're a little different than the later ones. The the rod bolts are different.

[00:35:53]I didn't realize that there was a difference, but no, we we've revved them to that RPM a lot.

[00:36:02]Thanks. I'll look into drive shaft compatibility.

[00:36:09]Fire my engine up this week for the first time. Nice. Ros and piston 6 L truck plus cam 11.6 E85 should be fun.

[00:36:18]That that motor could probably benefit from with E85. So, that should be cool.

[00:36:22]Let me know what happens. What intake and stuff is on there and what heads and stuff for the cheap car challenge? 15,000. What would you build for drag and drive?

[00:36:33]I don't know. I've never thought of a drag race thing.

[00:36:37]All All of my experience has been road racing and and um um top speed stuff, Bonavville stuff.

[00:36:57]How far would you run a factory 480?

[00:36:59]Would you do 6 to 700 crank, 5 to 600 wheel? I don't know. I have no experience with that. Um I know that there were guys here suggesting a particular um kit that you put in the 4080s. Um, and I think if you look at what Matt Apple did on his thing when he did 8 for8, he used a Junkyard 4080, but they did do some stuff to it. So, look at that for a guide.

[00:37:32]Uh, Bill is saying, "Chevy 383, you shouldn't need a cat. Timing can help.

[00:37:37]If it's EFI, you you can add timing at idle for peak vacuum and that will help.

[00:37:44]I've been looking into Gear Vendor's kit. Yeah, they do good stuff. It's not cheap. Adds overdrive to the Turbo 400.

[00:37:51]You can split gears, make it a seven-speed. They hold fourdigit power level.

[00:37:57]I wonder if I could pick up a second and a quarter.

[00:38:02]Do you think you're going to get that from splitting gears?

[00:38:14]I'm looking at the atomic fab surge tank setup. It looks nice and it's apparently used for 04 plus fuel tanks because the opening in the tank is larger than the older ones. Yeah, we'll have to look at that.

[00:38:29]How many MAC valves should I use for my boost controller for the next gen 7875?

[00:38:35]I want to set up three tune, 600, 800, a thousand. I mean, isn't isn't the tune isn't that just going to be different boost levels?

[00:38:49]And and shouldn't the number of MAC valves that you have be dictated by your controller?

[00:38:59]Globalize. Thank you very much.

[00:39:08]bolted your RHP turbo to my 48. But now comes the hard part where I have to learn to fabricate.

[00:39:15]What What did you bolt it to? Did you get a Did you get some sort of turbo manifold?

[00:39:22]Have you done a video on Holly ultra low RAM? I have tested that many times.

[00:39:28]In fact, we use uh not an ultra low RAM, only a low RAM, but it's not going to do anything different than a low RAM does.

[00:39:37]You have to have a lot of motor to need a manifold like that. And they're it just kills power through most of the curve.

[00:39:54]Let's see.

[00:40:02]Rick Port heads L3 intake good combination 7875 5-speed in the bair it's going to be on 12 pounds that should be a lot of fun.

[00:40:16]Why does everybody keep a dog What does everybody keep a dog busy?

[00:40:21]Tired of picking up fluff and he doesn't care about big bones anymore. He can finish up here in 10 minutes.

[00:40:35]How big is the dog?

[00:40:38]Can you get him to chew on a tire?

[00:40:41]Tim is fairly conservative.

[00:40:44]Yeah, especially at at Cruz, you can put a lot of timing in it.

[00:40:49]Saw the Betty interview. Yeah, Cle Crown Vic has made over 3,000 miles so far. It has ATF, a drip going, and a water drip on the diff to keep it cool. Curious how long go. So, it's still running right now.

[00:41:04]That's cool. Would a 408 or 416 kit get me higher numbers on pump gas without boost over stock bore and stroke?

[00:41:16]Yes, you can make more power with a low compression bigger motor than you can with a smaller one. That's what that's one of the things that um Tom Nelson does is if you look at his thousand horsepower pump gas things, they're almost always like 427s.

[00:41:36]Welcome to Turbo World.

[00:41:39]Would you recommend any shops in Southern California area that can balance a rotating assembly? having a hell of a time finding one since the place I've used in the past is closed.

[00:41:47]The L&R is is in Santa Fe Springs. They can do it.

[00:42:02]Richard, you mean the fun part?

[00:42:10]Scrolling. Scrolling. Scrolling.

[00:42:18]I have an L776 liter with an S485 ring gap. Would you recommend for this? 1000 wheel horsepower 85 out of the question of the setup. As long as the turbo that you have will support that.

[00:42:34]First time engine build, first time tuner. Is it possible to ruin my refresh 6 liter by tuning it barely any? Yes, you can. You can break it easily by having too much timing in it.

[00:42:49]Uh LS3 intake rod mod.

[00:42:58]He needs a NOS bottle like Richard's dog. I know. I got them um got them little NOS plushies and now he now especially Bruno carries it around.

[00:43:17]Robert, are you asking me what heads that we ran?

[00:43:21]Never tuned anything as a grain of salt on whatever I'd be saying.

[00:43:26]Have you ever thought about designing your own intake manifold? I have designed many intake manifolds.

[00:43:33]I've built lots of them.

[00:43:40]Does rod mod actually do anything? I don't know. I I tested one at BTR and I didn't see really any good results because I had people telling me that, oh, that's as good as a fast. And I'm like, well, that's a tall order. I mean, it's not a tall order if you rod mod a an LS3 manifold because a fast manifold doesn't add any power over an LS3 manifold anyway. So, that's not a big flex. But, being able to do it like on a Cathedral port one, you know, I just I I don't know. We didn't see very much. It didn't compare to like aftermarket manifolds.

[00:44:21]You can hurt an engine at idle.

[00:44:25]Okay.

[00:44:30]The goal is to overcome altitude and retain performance at altitude. How much boost would you recommend on a centrifugal supercharger setup? You're you can't alter as you go up in altitude from lower altitude. The centrifugal supercharger is not going to do anything. I mean, it's just it's going to make less power at altitude. That's what they do. There is a little bit of compensation um but not like a turbo because a turbo will spool up faster at altitude. In fact, you have to worry about it at altitude about it over spinning if you're regulating it at a particular boost level. I ran my Vortex supercharged Mustang, you know, down near it at sea level when I was in Southern California and we drove it out to the Silver State and it's a lot higher out there. Not the Yeah. Uh the Silver State. Yeah, that's right. Um the we were at altitude there so it's a lot higher. Um so it was better than an NA motor but not as good as a turbo motor building a 496 big lock uh street motor.

[00:45:35]I want to run flat tops and 100cc heads. Any previous experience with this type of setup? Where are you going to get the 100 cc heads?

[00:45:45]the I think Edelbrock makes one set, but the the other factory ones are the Gen 6 heads. Are you going to do that?

[00:45:56]And then and then why are you doing that?

[00:46:02]Do you know what the cheap options would be to convert my 69 Cougar? I like those low compression 92 351 to run both regular gas and E85.

[00:46:13]Is this a Is that a EFI one or is it a um is it a carbureted one? If it's carbureted, you can't you're not gonna be able to do both of those. If it's EFI, you could you could definitely do that. You do a flex fuel setup.

[00:46:27]How much ring gap would you recommend?

[00:46:29]Turbos of Borg Warner S485. You need you need six to six and a half thousand per inch of bore. So multiply your bore times 6,000 and that's how much ring gap you need.

[00:46:43]Seems like something an old-timer would do. Barted out myself.

[00:46:48]Should I run my site? Well, you know, and I and I want stuff like that to work. I And I remember talking to Tony Mammo and and Brian Tulie about this a bunch of times on on them porting fast manifolds because that when you when you talk to cylinder head guys, they do not like having they want to make sure that they port match everything. the throttle body into the manifold, the manifold into the heads.

[00:47:12]All of that stuff has to be port match.

[00:47:14]I'm like, that's great. I can understand that. And you're going to the nth degree on everything. You got to do that. But I just want to see it do anything. I want to see it make power. Like these ported fast manifolds that people do. Oh, yeah.

[00:47:26]It makes lots of power. Okay. Well, I just want to see that. I want to see it on a dyno. I want somebody show me numbers where it did that because I haven't seen it yet.

[00:47:34]Should I run my sock 48, Gen 3 tune, or try and get a sock file for a Gen 4, six liter, adjust it from there? Well, it's definitely a a a six liter is probably not going to run very well on a on a 48 tune.

[00:47:51]How would the truck plus behave on a 408 with twin 770s? It'll it'll work fine.

[00:47:58]you you would be able to make that whatever the turbos will support. You'll be able to make that much power.

[00:48:18]Should I modify my stock 48 tune? Yeah, we can probably we I mean we have tunes.

[00:48:24]So, if you need something tuned, we can.

[00:48:27]Jimmy and Joel can do that. Richard, can val springs lose seat pressure if the engine's been sitting a few years.

[00:48:33]That's a That's a wives tale, and I don't know if it's accurate or not. I could see where something like that could happen. And I see where guys that store them for a long time, which you shouldn't be doing anyways because I'd be more worried about rust and stuff, that you loosen the rockers so that the you're not putting um you're not loading the spring. But I have let my motor sit for a really long time and we just run it and I wasn't really worried about spring pressure.

[00:48:59]Perhaps you could pull out the 408 stroker and do some testing on on what I don't understand. Edelrox makes a thousand or 100 cc heads. Yeah, we mentioned that.

[00:49:12]Get a six liter file and use the compare feature in HP tuners that copy differences and tune them all. tune out all the VBT options. Bill's throwing some good stuff out there.

[00:49:28]I would like to run the Molly Motorsport flat top pistons, or would you recommend going with 120 cc heads and 20 cc dome pistons? I I would recommend that only because there's way more cylinder head options that are going to be in that range. and a 18 to 22cc dome piston with valve release. It's pretty normal for a big block.

[00:50:00]How much margin do you have under your max turbo horsepower? I didn't realize they were like injectors where you don't like running it at max.

[00:50:09]you if you if you want to make 800 horsepower, you should not buy an 800 horsepower turbo. 100% you should not do that with any not just ours, with anyone.

[00:50:20]Doesn't matter who it is. If you if you see a turbo from Garrett or from Borg Warner or whatever and they say this turbo will support 800 horsepower, you should never run it there because if you're wanting to do 800, you should go to a bigger turbo.

[00:50:42]I wonder those portion ports matches everything even if it doesn't show a game on the flow bench or the dyno.

[00:50:47]Yeah. No, I get it.

[00:50:50]You mentioned you have tunes. Is this new? Yeah, we've had tunes for a little while now.

[00:51:04]408 stroker incoming with twin 770. It's going to need some big tires in the back. Any recommendations for a good hookup? Does anybody Anybody have any tire recommendations for Scottish 400 cubic inches and the truck plus cam would light it off? It's fairly small cam. Yeah, Cougar would need an EFI system. That's what I'm guessing. Yeah, you can't. If you have a carburetor, it's either going to be an E85 carburetor or it's going to be a gas carburetor. It's not, you know, gasoline. It's not going to be both.

[00:51:37]And we got two more minutes. And we didn't ever I didn't even have a poll.

[00:51:41]What's just people going? We good. We had like lots of good questions and stuff. That's good. So, make sure go to richoldperformance.com.

[00:51:53]get the G35 turbo or get two of them because then you could make 2,000 horsepower apparently. Um, yeah, Jimmy just made series power with that. But, but we have with the turbos are in stock. So, we have T4 G42s now in stock and so there's lots of stuff there.

[00:52:12]If you want 750 horsepower, you buy 800 horsepower turbos. Is that enough margin to be safe? That's not what I would do.

[00:52:19]I wouldn't, if I was wanting to make 750 horsepower, I would not get our the RHV 800. If you're wanting to make up in that level, you should get a turbo that's going to be comfortable in that level. I would, if I was going there, I would get a G42 for the LS from a good source. Much of the finish on the port is just to look cute for the customer.

[00:52:46]Yeah, the a lot of that is guys want it to look nice and we want because that way we touch it we go oh yeah that's all smooth because then if it's feels smooth then obviously that flows better doesn't really though is it true for timing you pull two degrees per 50 horsepower yeah no that's pretty good and and we do four degrees per 100 but the thing is if we have um like on an LS if you're not running all the timing anyway in there that the motor can stand and you have enough octane. We don't pull any timing for a 100 shot, but we also are running the motor cold and it's not going to detonate.

[00:53:30]Going to try sanding down my main bearings. Hopefully, it'll work. I I have done that a lot on um thrust bearings so that we get the thrust clearance that we want.

[00:53:42]Can I run 11 and six with boost on pump gas and emergency? I have a flex fuel sensor.

[00:53:48]Uh, yes, but I wouldn't do it under boost. I would just drive around and get to wherever I had to get to to run E85.

[00:54:06]I know you're offering tune help. Yeah, for for the factory ECUs.

[00:54:13]Alabama's in the house with one minute left.

[00:54:22]Every every 50 shot you add 50 degrees of timing. The 50/50 rule.

[00:54:30]Yeah. 116 is a lot. And especially if you have a small cam um under boost that's not going to be and and you'd have to pull so much timing that it's just not going to be happy.

[00:54:44]Super chats and stickers aren't working.

[00:54:45]They're not. What's going on?

[00:54:55]Thanks for everything. Thanks for answering all the questions. I'm happy to help all that I can.

[00:55:02]It's all good.

[00:55:08]You need the red. What's a red green?

[00:55:11]On that note, it is time to go. That's the last question for tonight and I will see you guys all tomorrow. Make sure go check out the my Instagram and Facebook.

[00:55:19]also go to richaldors.com, but I'll I'll post something tomorrow with the dyno results on and we'll have we'll show a dyno run to be running it on the chassis dyno on the S2000 and then we'll show the power curves at the different boost levels because that's that's a lot of power especially for a little
