well, My car is running 15 psi, and please keep in mind that this it on maines 10% ethanol enriched 91 octane fuel. Right now my saleen supercharged car makes 519 hp and 498 tq at the wheels. It is on a super safe tune.
The car is running a JDM stroker motor, stock heads that have been cnc machined, stock cams, aftermarket springs.
This car has made 560 wheel before with 93 octane, non ethanol fuel but i simply cannot get it any more with out driving to NJ to get it.
If i change my cams, put on the CJ throttle body, and put on the ported blower hat to accept that throttel body, and magically find 93 octane fuel again, i could be well into the 600+ RWHP range on a reliable street tune.
obviously if i wanted it to be a dyno queen i could have a race tune done with MS103 vp fuel and make a lot more power for the track. With an auto and 534 RWHP this car ran consistant 10.6's
These blowers can make the power. If you want to push it more you can have the blower housing ported.
