We Ran StreetSpeed717's Twin Turbo C8 on the Streets and it's Insane!

We finished installing everything on the car! Now, it's time to dyno it, and then see how she handles on the street! The car sounds INCREDIBLE with the turbos to say the least! We can't believe how well everything turned out on this car. We're excited to share this feat with everyone, and hope you love it as much as we do!

You definitely found the limit of the stock clutch.That will be toast in no time....

[@frontspring1]

u mean clutches dct have like 7 clutch packs

[@C4Gixxer]

[@tommypdcantcopsht]

Grab America by the Flaps it’s actually one clutch pack as that refers to the whole assembly. It’s got two sets of discs, probably 5-7 in each set

[@guypascua8848]

667hp on 5lbs of boost, 230hp gain? That's insane to think what you'll get once R&D is done! GM is definitely watching and the engineers are thinking, "We've gotta 1 up LMR. Think we should give them credit for helping with our engineering design?" Nice methodical work! Thanks!

[@LateModelRacecraft]

Thank you!

[@MrPhatties]

Consider every 14psi of boost as a doubling of displacement over naturally aspirated, so at 5psi you're adding ~35% base power to the Corvettes ~500 at the wheels (as measured by others) which gets you very close to 667. I'd say it's a bit lower than expected but that this assumes perfect cooling of the intake air which is not the case.

[@chicago1680]

[@TheCanamman01]

@joshua dugas From what LMR said they want to keep it until all the R&D is done on the vehicle. Plus the transmission still needs to be tuned to hold all that extra power! Their end goal is get the c8 around 900hp but this can't be complete until the ECM is cracked open.

Stock trans slipping, what rpm did y’all cut it off at before it cuts power itself? 5, 6k? These KZbinrs are so hellbent on being first first first. I’d rather be first to hack the computer and do a proper tune as well trans tune. Not risk it and whoops 70+k wasted then wait for LMR to make me a new motor!

[@AndrewB383]

I mean, this is how progress is made, you can do this risky stuff for cool factor and research yourself, or, wait *years* for big companies to think it's worthwhile - they got the cash to splash, let them play.

Great job LMR. The potential is huge. Baby steps first. We are an impatient species but good things come in time. As a C7 Z06 owner I’m looking forward to the C8 Z06. Will trade in without hesitation. Can only imagine how turbos would sound and perform on a flat plane crank.

[@CWood91]

I hope when they can tune that trans is fixed cuz it’s looking like it might not hold 👀🤭.

[@guidoheeling1179]

i think they accounted in an additional like 200/250 hp from chevrolet, after that i think it will probably slip after a while, you can limit this by keeping it from torque cutting when running boost only at higher RPM's

FerrariLamborghini24 Its heated up by being compressed by the turbos anyway, then cooled back down with the intercooler.

Extremely understandable explanation. Seems like you've created your own Z06 or better with the twin turbos. It sounds really good. So Forged pistons would be required for reliability. What about the wrist pins, connecting rods, bearings and crankshaft, as far as needing to be replaced for reliability at the amount of horsepower that you are putting down. Also, the drive axles. OK. I will continue to monitor what you are doing to build the C8. It's a massive project, but we are enjoying watching you bring this C8, "up." This type of content is amazing. I really enjoyed this particular presentation, a lot. AF

Measure what the air temperature is at the air filters. It’s an amazing improvement if it needs a cold air box. K&N filters flow well but so does nothing and that’s about what they are. They filter out the grains of sand but not the fines. Also if the element oil gets on the MAF, it can mess it up. There are some better disposable ones. Congrats on putting the turbos up high and not hanging under the ass end!
