ZR1 question My friend got his zr1 recently and he has 300 miles on it. It started making a noise in the supercharger. It sounds like a intermitted gear or bearing noise. When I use my stethoscope probe on the impeller case you don’t hear it but if you put the probe 3 inches behind the belt pulley that’s were you hear it. Even if you put the probe right behind the dive pulley you don’t hear it. Now the dealer is telling him not too worry about it. They say it normal break in noise (now how do they know it’s normal if they have only had a zr1 too deal with before). Do you guys have any info on this noise or any other people that have delt with it? Also the dealer won’t give us the number for the performance center they said they are not allowed too.

The car has a Warranty right so when it blows up it the Dealer's problem.Just make sure they give him some sort of paperwork saying they checked it out and it is a normal problem just to back himself up.
Ive heard that is a common thing on the modified Eaton design. It is the lobes wearing into each other and the coating allowing the rotors to tighten up. Common in The Radix design which has three lobes so I can only assume the same would be true of the 4 lobe design in the R2300 in the ZR1. Superchargers are like women.... expensive and they never stop whining
I've bought MANY new cars and have had a similar situation once. My oil pressure was extremely low on a truck I bought. I had paperwork showing I brought it in with that concern. Chevy bought me a new engine the next year.
