Ever since I put my pro charger on it has been making a little bit of a chattering noise. Last week I pulled the belt off and checked to make sure all the pulleys were tight. They were all tight, but I did discover that when I grab the top pulley beside the tensioner pulley it makes a little bit of noise from inside the supercharger. It does this when I grab the pulley and wiggle it back and forth. I checked for leaks and metal in the oil, but I found nothing. It is not losing any boost either. Does anybody have any idea what this could be?

 

Did you check the oil?

.

 

Yeah, the oil looked fine with no metal shavings at all. I put the bottle in that pro charger sends. I found a posting on here where they mentioned pulley bearings. Could this be a possibility?

 

I was told that the clattering was because of the way the oil splashes on the gearset inside, and because it is a selfcontained unit not running an oil line to the oil pan like all the rest of centri's out there. My friend runs an F3 procharger on his T-bird and his has the same clatter as my little P1sc. He's pushing 32psi and 8100 rpm and he has NEVER had a problem with any of his prochargers.

 

listen to the video's on you tube, and see if yours is making a different noise

 

thanks. So far truck is running great. I just wanted to get some guys opinions on here.

 

so I went back and watched your video again and I don't hear anything not normal

 

It sounds normal to me too.
