can any of you guys tell me wich S/C makes the most power out of the box on a stock lt1. opinions anyone? i have decided to go forced in my ride can i get a strait answer?

 

ATI with their twin intercooler setup, or Vortech with their aftercooler. Both are real close in potential. The real question is how long will the stock motor stand up to the supercharger.

 

To restate the above, just about any SC can produce enough boost to seriously decrease the lifespan of a stock motor.If you really mean to ask about comparing low boost setups, I'd answer the following. The "safe" boost limit for a stock LT1 is ~6psi. At that level, there will be no significant difference between a Vortech or a Procharger, assuming they are both intercooled. The thing is, the Vortech "aftercooler" is expensive, so the Procharger kit may be a better deal.

thanks for your input what could i expect from ati or vortec at the wheels hp

 

My best pull ever was 441 at the wheels with 7 PSI from my S trim. That was with alot of bolt ons as well as a near perfect blower tune and zero belt slip.

My last dyno was a dismal 353 horses at the wheels which I receintly found out was from my springs and valves not closing all the way. They would close, but the valves would bounce off the seats and allow boost/compression to escape from the combustion chamber. Too bad I had to blow a head gasket to figure that one out.

I can't wait to get back on the dyno with my new ported heads/valve job/good springs and my for real blower cam. Gonna be interesting.
