Guys just in case you are intersted, i will be happy to show anyone how to change the pulleys and belt to gain4-5 more lbs of boost on the Paxton setup. IT WILL!!!!Void your warranty on the compressor BUT if that goes it is about 1500 bucks for a new one ( I dont see this happening tho). I replaced all of my pulleys and made some a little bigger and reduced the belt size from 110" to 108". With the stock PCM in the truck with it shifting at 5600 RPMS we were getting 10 lbs of boost. With the shift points moved to 6000 and the rev limiter moved to 6250 11 lbs. Now keep in mind that I have Striker heads and they FLOW like crazy. So, on stock heads maybe 12-13 lbs of boost (and I have headers). Most likely a fuel system upgrade would be needed for this mod tho....I have 42lb injectors and an Aeromotive Eliminator fuel pump, regulator, Vortech FMU, AND an intank Walbro255lph pump for backup.
Going to the dyno today and Ill let ya know the results...
