I have an ls3 in my 99 t/a.....

Which pulley do u guys recommend?

Tried searching but wasn't sure if there are differences in corvette versus fbody.

Best place to get it?

 

I wanted an ATI but it wasn't in budget right now... I landed and an SLP/powerbond. Ws6store is who I got mine from, killer deal!!

 

Is ati really double the price better?

 

ATI is probably the best. I went with Powerbond do to the price and reputation. The SLP and the TSP are made by Powerbond. TSP had the best price when I was shopping for one and that is why I bought theirs.

 

Ati is worth the price.. If you can't afford it though, powerbond/slp Will do.

 

Just go with the ATI. Its really worth it IMO.

 

Do these really have any documentation showing proven increases?

 

This is exactly what I want to know.

I've seen multiple types of ati udp...which is best?

 

Proven increases?

You won't find anybody saying, buy this UD because it makes more RWHP so it is better.

An ATI isn't better because it makes 5Rwhp and an SLP makes 3Rwhp. It is better because it does what it is designed to do better.

There is a reason that almost every single engine builder on this site sticks an ATI on the front. When is the last time you saw a high dollar build use something other than an ATI?

ATI is only a 10% UD while Powerbond is a 10% or a 25%. ATI does what it was designed to do better though, so it is the superior product.

 

We recommend and install powerbond here (also run them on our own vehicles). Great product and price. Yes the corvette dampers are different than the f-bodies so be careful with that.
