My car has a supercharger.

Ok, ok, it doesn't, but it sure as hell sounds like it does. There is a whining sound coming my engine whenever I accelerate in 2nd or 3rd gear at around 2-3k rpm.

The best way to describe it would be that it sounds similar to an 03 Cobra with the stock eaton under minimal boost. The pitch gets higher as the engine revs. After 3k rpm I can't hear it due to my exhaust .

Any ideas to what it could be? TIA

Some lids can make that sound, and I've heard there is a silencer thing in some of the lids that when removed makes it even louder.

 

you sure its coming from your engine??....if not it could be a problem in your drivetrain or diff.

 

I know the sound your talking about. Thing is Ive had my lid on for a while and the sound just started last week.

 

Next guess could be rearend, do you have any gears other than stock in there?

 

If an altnernator bearing is starting to go out, it can sound just like that.

 

I had a feeling that it was my alternator.

As for it being the rear, Im positive it isnt. As a matter of fact, my rear was just rebuilt around 3 weeks ago. Its silent as its ever been.

 

power steering pump can make that sound i think

 

I second that. When my power steering pump was low on fluid it would whine and sound like a weak supercharger (I guess). The rack used to leak like a siv and I always knew it was time to add more steering fluid when I heard the "supercharger whine."

 

What about the throw out bearing?

 

if its an alternator rev your engine in park and see if u can duplicate the sound
if u cant its not motor otherwise im with v8maro check your throw out bearing

 

I put some more power steering fluid in and the sound is still there.

I noticed that it only makes it when the car is under load. I reved it when it was in neutral and no sound at all.

At this point I HOPE its the throwout bearing, as next week Im getting a new clutch/flywheel/slave and master cylinder installed.

What do you guys think?

 

I know since I put on my lid my car has always made a little whistle when I accelarate.
Just giving you options to consider.

 

Definetely Not the Lid. It only happens under load. Plus, Ive had my lid for a while now and the noise just started.

 

sure its not your belt.

 

How would I check to see if its a belt? I just looked at it and i dont see any cracks or anything...

 

third.... mine made a sound likt that a while ago it wa slow on fliid.... you couls always spray wd40 or equivilent on the belt while it's running. it may last a minute but it may help you narrow it down. also i heard a while back that a guy on an lt1 had a chirping sound and it ended up being a crank pulley, if i remember right i think it was an underdrive pulley but nontheless. i'd just wait till you have your clutch, ets in there and see if the tob was the problem.

 

i have the same problem. i would also like to know what it is. my fisrt guess was a belt

 

Just a suggestion, have you tried pulling the belt off the car and driving it under a load? I�m not talking about going for a cruse, but a short blast.

 

When my rear end went out, it made a whinning sound. good luck to ya
