Ok I have been looking at supercharger setups for a long time and one thing that I am confused about is how to adjust the boost pressure. I know that changing the pulleys will change how much boost is produced, say the supercharger can make 14psi of boost, is there anyway to use a boost controler like on a turbo to turn that down to 6-8 PSI?

Thanks

sure u could do that. But y turn the SC fast enough for higher boost than u use? The faster u turn it the harder it is on it & the more power it needs.

Why would you want to turn it down. If you don't want to be hard on it stay out of the pedal when you don't need to go fast.

Yea since the only thing controlling the RPM of the blower is that pulley, the only thing you can do is change its diameter. But it is a little different from a turbo. If your not at WOT, its not feeding the motor any boost. In the case of a centrifugal anyway.
