just wondering about how much hp gain each psi is equal to.

just trying to figure out how much i wanna boost up to achieve the numbers i want..

thanks for any help given

It should be around 14- 15 hp per lb boost give or take a little. Take your baseline and subtract it from your known hp at low boost then divide that hp by that lower boost.

With headwork it may be higher and with a thick head gasket it may be a lower number.

 

alright.. thanks alot


and whats the average ctsc on stock psi dyno at? just for an estimate

 

Do a search, or look at the dyno sheets on the comptech website.

 

HP/psi numbers are influenced mainly by the dynamics of the head. All stock S2000 motors should have almost identical HP/psi numbers. The reason a good turbo system has a higher number is because there is much less parasitic drag on the motor. A Comptech supercharged engine and a Lovefab turbocharged engine will both produce the same HP/psi numbers, but the Comptech will eat a certain amount of power in spinning the charger.

 

Interesting point but so off topic.

That drag is about 70 hp at max impeller speed with the Vortech V2 SQ SC. I have not seen numbers published for the Comptech.

 

Not off-topic at all. Just clarifying what HP/psi really means. Someone is bound to ask why a turbo produces a higher figure...and there is a reason for it.
