I'm pretty sure the PTK Gen II kit 355 CI LT1 made 980 @ 22 psi on a 76mm. When they stepped up to a 88mm @ 24psi it made 1012 rwhp. I believe the downpipe was 3", so that was probably not helping, but it looks like a 355 can make close to a 1000hp to the ground with the wick turned up real hard. Those numbers were from older designed turbos from 1 to 1 1/2 years old. I'm thinking this new GTM 76mm T-netics might be the hot setup for my target of 18 to 20 psi. I'm really trying to stick in the 76mm range to keep my spool up decent. I agree with you SBC GENII I should definitely talk to Jose @ forced inductions

PS: What garage do you have your car at in T-town. I looked at your progress pics, looks good.
