oil pressure looks good at 8000+?

awesome indeed! I'm curious how are you guys keeping your trans alive as well as the axles w/ that kind of power. Even at 450 hp, drivetrain likes to go boom. Either way, amazing work like always. The best! #goals

I don't think its as big of an issue as the internet has made it out to be. Obviously some have legitimately broken. Some of the road race cars that did had right around 330hp, and when I spoke with someone from the team they attributed it to the way the cars were driven on track.

I personally have yet to have an issue with breaking gears in the stock trans. The axles aren't going to break unless you wheel hop or are jumping curbs. Get solid engine mounts, avoid wheel hop, and that will help a lot.

Are there downsides to limiting VTC?

It makes more power with the cam from bottom to top, so no downside. The full swing of the gear on a stock engine is used rarely, and its all different now with the engine modifications.

Perfect, however it is a built engine with some oiling mods. I haven't turned a stock engine that hard.

Great stuff 4piston team! Those are some meaty power gains!

As you guys continue testing, it would be pretty cool to see what these cams can do when paired with your typical FBO vehicle (PRL/HKS IC, HVI, DP, Exhaust, Inlet) as a lot of people are kind of at this crossroads before deciding whether or not to call it a day or hunt for more power which typically revolves around going with a larger turbo.

How do you expect the TR2s will interact with the turbos on the market right now like the MHI, Rampages, and P600? I know you didnt really see any change in the onset of boost on the stock turbo, but do you expect any difference with the bigger ones?

Cant wait to see more test results!

That is why I put the 7163 back on my car for the test. The 64mm and 900hp wasn't useful info to anyone. I think that 7163 is a good representation of similar flow to some of those popular aftermarket turbos.

We do have some bolt-ons coming for the other car....some of the stuff has been tough to hunt down to be honest. We got a Mishi Intercooler setup here and Eventuri intake with larger MAF that shipped today from Evasive. We tried to get some other stuff but it seems a lot is out of stock. We can push that thing pretty hard but I'm trying not to clean up oil on the dyno and punch a hole in the block. Would be cool to see over 400 on 92 oct with 21psi and 9 deg timing....not that this would mean much to anyone reading.

Gonna have to link up with @kefi, his built bottom end and P600 would give some great results that a lot of people probably wanna see!

Great work as always

“Would be cool to see over 400 on 92 oct with 21psi and 9 deg timing.”

I would love to see that! Ideal setup from my perspective.

This is awesome, would love to see what they can do a full bolt on custom tuned car. Can maybe satisfy that itch for a slight bit more power without going turbo swap.

Very awesome stuff Luke, cant wait to get my hands on a set or two!

Man… that is absolutely impressive!!! You guys are the best, can’t thank you enough for all you have done for our cars over the years!

Put the Mishi intercooler setup on today. It’s a nice kit. I’ve had several intercooler and this one is a pretty nice setup. Now just waiting on the intake and we can dyno again.

Howd you get one without the M on it? If my name didn’t start with an M I’d of tried to get rid of it a long time ago

My wife name starts with “M” that was the perfect excuse for get an aftermarket intercooler ?
