VK 56 is a low compression engine (9.8:1) and stock G37s make 600whp on high compression (11:1) engines. So i think it would handle some boost (10-12psi) very well. I have yet to hear of anyone proving either of us wrong though. So i guess we agree to disagree until someone tries it, so far i have seen Titans hold 9psi and over 500whp on a stock bottom end however I think it was a single turbo and i am not sure of the size.

 

I know I'm bringing this from the dead but does anybody know what happened with this proejct? A v8 g37 sounds like a dream come true!!!
