Washed the Bonneville yesterday.










I was getting my supercharger oil changed and the guy who was doing it has a GTP and said that he didn't think my pulley was stock. What do you guys think?

That'* because it isn't.

BTW, PLEASE replace those belts. They are in terrible shape.

It doesnt look stock to me, mine looks different than that, I suppose it could have changed from year to year, but we both have the same engine, so I would think they would be the same.

Yeah I have Two new belts in my trunk.

I'm taking it in for a tune up to my uncle and he'll change them for me.

I have teh same year as you, and mine didn't look like that. Messure the pulley. Stock is 3.8" where the belt runs.

Also, have you ever changed those belts? They look rather cracked.

It'* not hard to change them. The supercharger belt goes threw a motor mount. But there'* a knock out pin in the front. You remove a bolt, then I think it was a 5/16 socket to turn out the stud. You may have to loosen the other bolts, then you remove a spacer. I seem to remember I had a thread covering that, I'll go back and look for it.

Ok, found it, man, did that back in 2006.

Yeah i have major slippage whenever i floor it.

They're getting changed right away.

I'll go and measure the pulley right away, the car feel'* like it has more then 7 psi of boost.

The guy at the shop also noticed a little chip on the end of the nose from someone changing it without the pulley tool.

Definitely different...

So i just measured the pulley,

It'* either 3.4 or 3.5

I'm thinking its 3.5

EEK. Well, you better get a stock pulley on there, or do the proper mods needed to run that pulley. You are probably killing your engine with KR (knock retard).

I'm not even sure you can run a 3.4/3.5 with a tensioner pulley change. (I'm not sure on that, I own a Series I.)

EDIT - You did measure the pulley across the belt ridges, right?
