slight supercharger whine on throttle

mults · 05-21-2018, 09:37 AM

Was the throwout bearing replaced with the exterior CSC? I've heard these bearings make all kinds of noises, especially when there is no load on them...Just my two cents.

Keep us posted as to what you find.

I have a small amount of chatter, but not a significant amount more than the stock system. I understand the noise you are experiencing, and it seems to be a different animal. I wonder if it might be something to do with the CSC delete?

This doesn't seem to be your issue, but I'll throw it out there. A/C compressors will whine when they are dead/dying.

Thanks for the responses, and about the throwout bearing not sure tbh i'd have to ask. Unfortunately the shop that did the install is closed today so it'll have to wait a couple days since im off Wednesday.

I'll post up a video of the sound today, so maybe you guys can get a better idea of that sound. I personally don't think its normal but i guess we shall see!

Found a vid on youtube that describes my issue perfectly.

"First rev is with the clutch pedal out, second is with the pedal pressed in"

The guy who posted that video said "turns out it was the input shaft. had to get the transmission replaced" ... god i really hope not, i just spent a ton of money to fix this csc issue.
