With good rod bolts, JWT cams and JWT valve train, Sasha's VQ35HR with 370Z crank made 414hp atw which has to be 480 @ the crank see Kels takes Mosport with fastest practice, pole and race win.. then we broke her. : OnPoint Dyno

Sasha has already done most of the development work including overall induction/exhaust lengths, trumpet sizes, airbox capacity and a bunch of other stuff.
What this demonstrates is that nothing is simple, it is all interconnected and what you need to do is test, test and test again.
This has already been done, no need for more test pilots .. just use the lessons already learned ... |
I wasn't surprised to see the shorter trumpets made a bit more peak, but what (if anything) was ever found regarding overall intake + exhaust length?
Did you guys just end up running open ITB's with foam filters and no airbox? I see the hood had some ducts cut into it.
