Well I wont post any links to avoid violating any rules here

(No replies with ebay links please)

but I did notice that if you search for "LS1 pulley" youll come up with a $115 new underdrive pulley. Then youll see its the same exactly pulley sold by SLP for $199 (they claim it as their own, its relabeled)

Company who makes them is Pro-Race

Part # 32560 for fbody/gto
Part # 32561 for vettes

ASP does make their own pullies. I have been to their shop in Stafford, they machine them right there. Auto Specialties Performance used to make pullies for "other" companies, not sure if they still do.

The SLP Pulleys are Powerbond pulleys.

Both the "ebay" aka Pro-Race and powerbond pullies aren't worth the savings IMO. They're a good bit heavier than the ASP pulley, and won't yield the same gains. The difference isn't huge, but if you're going to put a pulley on the car do it right the first time.

Doesn't the ASP throw belts more often than the SLP or powerbond though? Thats what I hear anyway. Not speaking from experience.

I have never thrown a belt with the ASP pulley, not say it can't happen. If wrong, or worn belt is used, I guess its possible. If the pulley is not entirely seated all the way I could see that walking a belt as well.

I have the eBay pulley which looks identical to the Summit Racing and BBK pulley.

It is SFI approved and has high retention walls. It is 11.5lbs from my measurements which is about 1.5lbs more than the high priced pulleys.

I dont even see it on ebay.... and if i got an u/d pulley, would i have to run a new pulley on the alt.? What if I do? what if I dont?

I have yet to install.

I doubt 1.5 lbs. is going to make a big difference. It is the 25% underdrive that you will feel.

They are high. I have one.

Running a new pulley on the alternator is up to you. If you run a lot of electrical devices or a power consuming stereo then you will likely want a new alternator pulley. Most people don't change the alternator pulley. The BBK set that looks exactly like this pulley comes with an alternator pulley.

Pic with the alternator pulley and the high walls.
