I did a seach and couldn't find anything so..... Well I took my car to go from 10 psi to 15 psi. Well the problem was my car only made 6 psi and 240 RWHP and was running very rich and last summer it was running 10 psi around 300RWHP. I would assume something is wrong with the supercharger since Ive never changed pulleys before and it doesnt whistle like it use to. Has anyone on here rebuilt a supercharger before? if so how much did it costs? or do you guys think that something else could cause a drop in PSI like that? any info would help.....

Re: supercharger problem......
check for boost leaks? rebuilding a supercharger isnt too bad and only takes an hour or two with the right tools. Bought my rebuild kit on ebay for about 115 or so and i love it.Dave:

Correct me if I'm wrong, but you have Mach Perf. ATI kit?Originally posted by derkyboy187
It just sounds like a really bad belt slippage.

Re: supercharger problem......
Yes mines a mach kit. Im hoping to put pics on here now that I have a digital camera, but I dont have my car at the moment. I looked for rebuild kits online and couldnt find any. We were looking for belt slippage and it didnt really have any. I was also looking for leaks and couldnt really find any places where it could leak.Comment

Have you tried asking the guys at www.superchargeronline.com ?Originally posted by derkyboy187
They'll be able to make recommendation.
So did the whine changed and you lost boost?

Re: supercharger problem......
thanks for the help thor you were right.....the idler arm was broken causing belt slippage and the belt to stretch. For some odd reason though the tune I had before hand was bad and my car was running very rich. My car came in running rich at 240 Wheel HP at 6 psi and and left 291 Wheel hp at 11 psi, but the computer stopped the run at 5000 rpms since my 36# injectors were doing 130% duty cycle. They told me I need to go up to 42# injectors and maybe switch to a bigger intank fuel pump and get rid of the inline. Have any of you other guys switched your intake fuel pumps or do you guys think I would be fine just getting bigger injectors?....because I know you have to drop the rear end to get to the intank. Another question is does anyone know where I could get 42#s for my 02? for some odd reason the 02s are the narrow bodied ones.Comment

Re: supercharger problem......
I would def. ditch the inline pump and go with the walbro 255 intank, then see if your needing the 42# injectors, with the 36# injectors and walbro 255 you should be alright. I would try that first before swapping injectors.08' L76 6.0L 4X4 Chevy EXT.Cab LTZ Vortec MAX with Snug top cover, Dynomax exhaust,Hptuners& K&N intake
