Wouldn't he then get a thin film of oil all over the engine bay?

Can't wait to see the finished product.

Hope you get your refund from GTM though. Things do not look good for them.

It sure is...T25 on the left (found on most TT kits), and BP's "smaller" (62mm) turbo on the right:

Now that's what a call picture of the day!

bigger is always better but the advantage of the T25 is less turbo lag so it all depend on the customer needs right?

Ahh, but remember, with a twin scroll you have the energy of all 6 cylinders driving only one turbine wheel, while utilizing the power of exhaust scavenging due to equal length primaries. So nothing is really lost as far as spool goes.

what a beauty bro!!!

Big boy housings make big boy power! We did 496whp at 7.8psi on the S&R Performance kit, look forward to comparing the power delivery and power output between the two kits once our friend Puckshaw finishes his installation.

Looks good so far, great job tackling this project yourself!

Thanks,

I think S&R uses the V-band turbine housing though. Those are small (T3) housings...compared to this 1.15 a/r T4. IMO the T3 housings and the V-band are too small for the VQ37VHR, as they don't flow enough. I did a bunch of EBP testing, and know that the T4 is the only way to go, since these engines have a very high VE even at 7000rpm. That is a lot of exhaust gas you are trying to push through, so the housing has to be large.

Yep, it was a .82A/R v-band if I'm not mistaken(dont quote me on that). They work well on the 4cyl but yeah the VQ37 is a beast and I can certainly see a benefit from the larger turbine.
