my engines getting rebuilt and I have a mp supercharger, it already has some slight porting on the inlet side where it connects to the plenum and the tabs on the top have been ground down..
what I'm wondering is this: are the 2 ports on either side on the V on the top of the supercharger ( where the hat goes) are those silencing ports? my mechanic mentioned to me that if I want some extra boost from my sc I should weld those ports shut and open the V up a few mm's...is this true? I have seen a sc on craigslist that had those 2 ports welded shut but thought that it would hurt flow since ur closing off inlets..
can I weld shut those ports and leave the V alone and just have the sc sound louder? or will that hurt performance? should I weld the ports shut and open the V up like I was told? or should I just leave it alone?
its a mp supercharger with a mp plenum and my setup will have a 7% pulley on the sc, 75mm Tbody,42lb injectors,3in intake, 73mm mafs and stock exhaust but hollowed out cats..
anyone done this befor?.......
