I have a 94 mustang gt with a Vortech v1 supercharger. when I hit boost I hear a metal grinding noise and it wont hardly boost. Any suggestions

when you take the belt off and you spin the pulley by hand, does it feel like their is resistance?

I took the whole thing off, and when I spin the pulley. it almost sounds like a bad wheel bearing would. And there is SOME resistance. Sorry it took so long to reply......

At the same time I change my cam, I'm shipping my V1 to Vortec and for
$350.00 THEY replace all the bearings and seals.

Dang I should really look into that. everything seen is like almost 700 bucks

sounds like it needs a rebuild. there should be no resistance or noise when spinning the pulley by hand

FML, how hard is it to pull it off and run without it. and btw it has not been tuned for a supercharger. Hence the 6 pounds of boost, and it likes to blow black smoke when revved and when you get on it

if the motor isnt tuned for the sc then it should run the same without it. just hook up the maf like you would to the tb as if it was stock.

even at 6psi you should do some tuning, ie pull timing and bump fuel pressure, or run an fmu

do a compression test, black smoke is never good.

It also misses bad if I try getting on it. What about the oil lines?
