I just put together a .030 over 502 with dart pro1 heads and a 741 cam.Pro charger with 7 psi boost and it made 815 hp at 5500 rpm and 800 ft lb at 5000 rpm that was on 93 octane so it can be done.

I have a complete set of 575SCi uppers for two motors, complete with everything except the cool fuel system. Both wire harness, upper & Lower, Intake, supercharger, throttle bodies, flame arrestors, distributors, coils, hoses, belts, pulleys, computers, brackets, thermostat housings. You can have a factory look $5500. PM if interested. Merc used these with bravo drives.

Supercharger USA have a popular 8-71 blower kit which produces around 840hp! im looking for something like this, however, i had never heard of supercharger USA before...so i would like you guys to give your opinion on them, and wheather there are better alternatives?

Thanks!
Try Marv Hineman at http://boostdaddy.com/ 386-569-7226.He was the head guy at Hot Boat .He is knowledgeable in building blower engines.

Iv heard there high volume Supercharger USA ,something about a back log?

Rob
