how to get more power out of a stillen supercharger kit?

The stock block is probably good for ~11PSI at the limit...

Not only does the 928 impeller produce more power at the same impeller speed...but it also has a higher ceiling as Mr. Squeeze described. I don't know if the top RPM of the SC is limited strictly by the impeller or not, but all in all, this SC + the 928 Motorsports impeller has the potential to go well into the 500whp range with some internals. Hell, it can probably be enough to push those upgraded internals to the limit too.

The other advantage is that you can get the same power with less wear and tear on the SC unit since it will be spinning slower than the stock impeller would be.

dal1307 I do not have the pulley anymore I damage it because taking it off.Those pulleys had loctite,and was a pain to remove.
