also the end use of this will be for my rally cross car. I don't need A LOT of power, since with he 4.78 gearing i doubt i can put down more than 200 hp anyway.

a few other questions:

1. I currently i have a 12a engine that is in good operating condition. If i wanted to step up to the 13b as described above, would i only need to order a different lower manifold and re-tune? I want to ensure there is some flexibility.

2. Also, assuming a stock 12a engine, when would i start to see positive pressure and when would i see full operating pressure? Granted i am at a high altitude, but i can rationalize the information.

3. as for the intake to the supercharger, i see there is a weber adapter. Is it included in the kit? If not, what is the extra cost associated with it? I plan on running a weber style EFI throttle body and a MS2 for fuel control.

4. is the supercharger safe to use E-85 with if the injectors are upstream? Or should i save that concept til i have port injection with the 13b?
