ASP Pulley.

Expect around a 10hp increase.

are there any downsides to getting the asp pulley? will the car still idle the same and everything?

Anyone know of a site with instructions on swapping out the stock pulley with a UD pulley?

Yes you can have charging problems if you are running a system. But that can be solved with the overdrive pulley.

I couldn't find it on LS1howto.com. Are you sure it is in there?

Should be in the cam swap guide.

If search is working I will find the link for you.

I think I found it. Is it in the cam and valve spring swap?

Will i have to worry about loosing my AC's power?

I'm runnin a pulley on mine w/o any aftermarket stereo equip (all stock) and I can notice the headlights dim a little at low rpms (near idle) and also they will slightly flicker at idle too...kind of annoying but I don't care that much. Could fix it with a different alternator pulley to make it spin faster.

Yah about that... a heavily modded GTO (LS1) got 2 tenths from his. My passengers say the AC blows harder when my foot's on the gas now that I have the pulley... lol
