I have several cars with centrifugal SCs but I recently bought my first Whipple. I recently bought a 1991 NSX with a Whipple SC. I noticed that it rattles at idle but is quiet at rpm. When you drop it back down to idle ir rattles alot then it settles back down to a smaller rattle when the idle stabilizes. The rattle is quite noticeable inside the cabin. Reading thru the threads on Prime, I understand that rattle is normal for older Whipples? Is there things I can check like oil or play somewhere or??? Can anything be done to lessen the rattle besides turning the stereo up
Here is the pic of mine..I am not sure how old it is but heres a picture. Are the newer Whipples quieter?
