How much boost pressure can a built VQ37VHR withstand?

Yep with a N/A build you're powerband is crazy good. Probably feels like 500whp with that tack slinging 8k RPM.

Yes and no. If you're full throttle you will blow all 3 gears with normal street tires.

I for one can get traction peddleing 1st and 2nd gear catching at the end around50ish MPH. Just my experince.

Best DynoJet number guess is 480whp/450wtq @ 10psi. I do have the diff bushing upgrade which seems to help.

10psi 480whp/450wtq is the perfect street use power. Just enough to run decent 11's with good driver or enough to blow the doors off a C7 on a 40 to 120mph pull.

It's your build, your goals. VQ37HR don't need to be built.

It blows the doors off a lot more than a C7, not that I would know

Yep. Even with my 8 PSI tune I took out a C6 on a 200ft, and kept up with a GTS Viper.

i guess your tires suck then cuz the ones that i have hold mine just fine and i run the piss out of it everyday....today on the way home i was running 13psi and did a pull against my wife in my talon and still didnt blow off the tires (after tires are warm) and went from 30 to 170 no spins...

My uncle is one of the owners of jegs and when i was younger i raced legend cars..we only did 4 to 8 races a year.i always said it had to much power...he said no car has to much power it just means your driving skill has to improve....he would always say control the car dont react to the car...is what i'm trying to say is we r not in a honda you dont just slam it to the floor and hope it goes where yu want...
