That totally sucks.

I baught it at a auction, and didn't get to drive it before buying it. I did get a pretty good deal and am very happy with the car. I always figured the boost controler was bad, and I finally had time to go through the car, I guess it was a little more. I found a SC for $150 so that should solve my problem.

I don't know, it's gay.

Makes no bad noises, the bypass valve is working perfect, so I am quite confused. A guy on the bonneville club forum said to check the couplerin the supercharger, its a plastic coupler that connects the nose shaft to the supercharger screws. Apperently it only lasts 70-120k miles and since my car has over 180K it may have broken and thus my superchager won't work. So I am going to take the nose section off of it monday or tuesday.

I was mainly wondering if anyone had any experience with these engines.

Mike

This is one of the more common places for the 3.8 SC motor to have a problem. My brothers GTP had teh same problem you just gotta loosen the bolts a bit push it down as hard as you can then tighten the bolts again. There is more involed but its been a long time since i did it and i don't remember much but you should be able to find the procedure on those forums I would think.

Is the blower pulley keyed onto the shaft or is it a hub setup? Pulley isn't slipping on the shaft is it? Or, belt slipping on the pulley? (I would expect in a stock setup it'd only do that if the bearings were shot)

If the bearing went out it should make a lot of noise but still should produce boost

Ya, until it seizes up. But I know mike knows alot about cars and wouldn't ever let it get that far.

But I know you would have noticed that before it was to late. The car isn't throwing any codes is it?
