Any 370s running higher than 20psi?

With high compression your are already generating alot of heat and adding an additional 20psi is going to blow the VQ37 to kingdomcome. I think the most boost you can run on the VQ37 from what I've read is around 8psi max on 93 oct. and that's considered high. When I had my Evo I was running 22psi daily driven and 24psi when in race mode all on 93octane.hehe.

Even though you can push 500awhp on the stocker that's not an everyday thing. I ran 22.5psi consistently on a daily basis and 24psi on colder days and that's on a stock td0516g/10.5 hotside I dyno'd low but ran faster on the street then others that dyno'd higher. Weird.
