[00:00:00]Heat.

[00:00:15]Heat.

[00:00:22]Heat. Heat. N.

[00:00:55]Purchase your tracks today.

[00:00:59]>> Got a Porsche in today with a LS in it.

[00:01:02]A big old big old procharger on this thing. It sounds wonderful. Hopefully I'll be able to get tuned today. M's taking out the field prompt assembly.

[00:01:13]It's going back in.

[00:01:15]>> But we can test it by just >> hooking it up to the battery and see before we go through the trouble of uh >> Yeah.

[00:01:21]>> running this thing all the way through the car.

[00:01:25]>> Trying to get the tire steering pump to work. Fresh new tires for the front on a Porsche.

[00:01:32]Some Kindles 245 40s.

[00:01:39]>> They're trying to get the fans to work.

[00:01:42]And then right now we got a Miata on the dyno.

[00:01:47]Pretty sick looking. Looks like it's meant for track racing and stuff like that. We got the Porsche on the dyno.

[00:01:57]We had some stuff to get over. And now we've already got it all done. Fans all plumbed in and all wired up.

[00:02:08]Woo!

[00:02:10]Fans are all wired up.

[00:02:13]Gary pump's all wired in. Now it's just up to him to tune it.

[00:02:20]It's about to be sick.

[00:02:34]Crazy, >> huh?

[00:02:35]>> Things crazy. He's crazy.

[00:02:39]You fell asleep.

[00:02:40]>> I was.

[00:02:45]>> He's currently trying to get it so he can dial it in so he can finally do it.

[00:02:49]First pull. Any about to get some race gas for that Porsche.

[00:02:55]This is going to be crazy.

[00:03:01]Getting some race gas.

[00:03:03]>> That's crazy.

[00:03:06]All right, we put it on race gas and you can already see the difference.

[00:03:12]We'll probably make it more and it'll be a healthy range for the motor and stuff.

[00:03:18]This thing is making some jam and it sounds wonderful.

[00:03:30]We just had to fix the valve stem on this cuz it popped off inside the tire.

[00:03:35]So, we just got it all set up. I put the tire back on.

[00:03:43]This thing just made 600.

[00:04:11]I got to drop the engine by tonight.

[00:04:14]Get the head redone or swap heads.

[00:04:18]I think it messed up a valve.

[00:04:21]It's going to be a late night for them.

[00:04:24]Like I was saying yesterday night, they pulled the motor out, got the heads off.

[00:04:29]It ended up bending a valve right here.

[00:04:31]You can see where it was hitting, but he's got a head gasket and he went to go grab some heads uh that he has so he can get this all on there and then adjust everything so that this motor can go back in today and get running so that he can try to make it to LS fastest. But everything else looks healthy. Looks like a smooth smooth happy motor other than that. So, here soon. I guess he already brought the heads and they're right here. And these look all extra clean and [ __ ] Freshly decked. It looks and looks good to go. This thing should be ripping in no time.

[00:05:09]He said that these were junk because of the valves. They're different. This one's different from that one. Those two are the same. That one's different. Same for this. And on the this side.

[00:05:24]Some of this is aftermarket like one keeper aftermarket ones stock and then they cut down the valves to make it fit which is pretty crazy. But he said he had some more. So these will work and they're brand new apparently. All new stuff. So this thing will be getting put together here real soon.

[00:06:05]all dressed up.

[00:06:07]>> Ready? Look.

[00:06:08]>> Oh yeah. Oh yeah.

[00:06:10]>> Dom's got to do some wiring before this goes in and then get this thing chooched up. has 300 coming together.

[00:06:24]>> We had to punch these out on >> for the steam port.

[00:06:29]>> Luckily, he didn't have a water pump on, so it just fell straight out. And these are steel, so we used the magnet to grab them. Sick.

[00:06:44]Motor's almost there to go in. Just got to adjust it a little bit. He's going to put the slave on and then this will be almost there.

[00:06:56]Back alive, boys.

[00:07:02]Just like that, she's running again, boys.

[00:07:05]>> Wow, that's hell of a car.

[00:07:07]>> You'll see in just a moment.

[00:07:11]There she is running again.

[00:07:25]enough brakes to make it before the street.
