Well, I'm most likely going to be making the switch from the Vortech to a GT35R setup within a few weeks. I'm not going to be putting on a 3mm inlinepro head gasket for a while. I know the S/C can "generally" have a little more boost on stock compression than a turbo (~12psi max for S/C) due to not being fully boosted at lower rpm. Question is until I get a 3mm head gasket, what would be sufficient? I still would like to make some decent power and was thinking of getting it tuned somewhere in the ballpark of 8-9psi. Does this sound safe?

 

I ran 7.5psi for over 65k miles (~300whp on a small'ish turbo) with no problems at all

 

What kit are you going with? You could get around 400 whp on a Lovefab kit at 9 or 10 psi. Just have your tuner keep the timing back some.

 

GT1 manifold, GT35R.

 

I've run 10psi on my gt1 mani, gt3071r, for a couple months now with no major problems. Its really all about the tune and how much you trust your tuner's ability.

 

How much power did you make minitoyota?

 

375whp at 7psi and 425whp at 10psi

 

Thanks!

 

No problem. I was going to do the 3mm HG as well but I was more then happy with the power it made at 10psi, I decided to hold off till this winter and build the motor instead.
