GT3076R on GSR. Psi Question.
Hey guys,
I've been searching for the past few hours and haven't found anything.
I picked up a 30R from my roommate for a really good deal, I'm going to be using it on my stock bottom end GSR until I build a bottom end next winter, I'm curious what boost pressure I can run to make 300whp or a little over with out going crazy. I'll be using stock GSR cams as well and no head work.
Thank you guys for the reply, I appreciate it.

Re: GT3076R on GSR. Psi Question.
Too many variables to really gauge how much pressure will be needed for a 300whp goal such as: Engine health, tuning quality, fuel type and supporting modifications.
For comparison's sake, my basic stock sleeved 10:1 piston/rod GSR with ITR cams made 334whp on 12psi with Shell Vpower 91 pump on a conservative tune @ 3500ft elevation.
I wouldn't be surprised to see 300+whp out of a stock GSR engine at the same boost pressure (11-13psi) on pump fuel @ sea-level with a decent tune.
Still tough to say, too many variables. Just get it tuned and see what it takes to get 300. If you're tuner is experienced, it should be easy.
