How much boost pressure can a built VQ37VHR withstand?

When I was running my 350z at 430whp...every time I got on her hard I prayed she would hold together..lol..

Built engines offer a piece of mind and allow you to have more fun vs. riding the ragged edge.
But at the same time opening up the engine can bring about a whole new set of issues.
I would say this car, if taken well of can survive quite well at 550-600whp on e85. A prime example of that is Phunk, he has 50-60k miles with his greddy TT kit making over 550 (if not 600) on e85.

In terms of boost pressure, the highest I have seen currently it John's 370z TT: John’s 370Z TT+ |
They hit about 25PSI though it seems and 800whp & 700TQ.
fuct, jwick, Rid3_FaM0uS and 2 others like this.
