Things to check for:

* Belt slippage, look for belt dust on the blower housing.
* Boost leakage, pressure test the system to make sure there are no leaks.
* Bypass valve opening and closing properly. Make sure that when the butterfly is in the closed position that there is only a slight air gap.
* Make sure the air filter is clean. A dirty air filter will lower boost levels. Try a run without the air filter installed to see if you pick up boost.
* Impeller rpm - To determine the impeller speed, the following formula is used:
Maximum impeller speed = crankshaft pulley diameter (N1) divided by supercharger pulley diameter (N2),multiplied by the step-up ratio (4.10 for the P-series/D series - 5.40 for the F series), multiplied by engine rpm at redline. 62,000 rpm is max rpm for the P-1SC.
* If everything is working as it should and you still want more boost, send the P-1SC into ProCharger to have it upgraded into an D-1SC. Bob
