So i picked this supercharger and aftercooler kit and installed it yesterday. The kit has approximately 18k miles on it per previous owner. I am running this basically stock set up with 6lb pulley. After install, car runs extremely good however i am getting some strange chirping noises out of the Novi 1000 head unit. Its hard to explain the noise other than a chirp and it is very intermittant, seems to be no ryhme or reason to the noise. I have loosened the belt, tightened the belt, checked oil flow. Any suggestions on what this could be? Bearings maybe? New to this but don't think that a supercharger should be making this noise. Thanks in advance for any help.

 

will try to post video if possible.

 

if its chirping it is likely the bearings.i had the same thing happen,i replaced the bearings and it went away.

 

Did you do it through superchargerrebuilds.com?

 

no i rebuilt it myself.its actually very eazy.you just need the new bearings and a press.i was able to find the bearings local through a friend.i do not have the parts number since it was a bearing shop he got them from.

 

Neat! No chirping here but good to know should the day ever come.

 

I have had the chirping before, it’s the bearings but it went away after re aligning my blower bracket, it was off center a bit. Also if the belt is too tight that can have the same effect. If your bracket isn’t aligned then it will slip on the pulley easier too and over tightening will need to be done to compensate. I got lucky in my case and didn’t have to replace the bearings, put thousands of miles on since with no more chirping.
