Question about smaller pulleys
I have the stage 2 kit on my car and am wanting more power...how small of a pulley can I put on that will work with the stage 2 belt? and how much of a power increase could I expect out of this pulley?

I am running a 2.5 with the stock belt. So you can pretty much go as low as you want. With my current setup, I expect 285-290whp but I have yet to get a dyno.

With him having the belt that comes with the Stage 2, he should be fine though...

thats awesome! now here's another question will the stage 2 injectors keep up with the 2.5? also is it just a matter of taking off the supercharger and slappin that pulley on?

He'd need a lot more to get that high of hp...he would definitely have to get a big cooling system (my current project) which will allow him to get it tuned and that will allow more timing, etc.

Yeah I of course got the bigger injectors and a tune. The larger tensioner pulley too. But I was just staying if the only thing he was worried about was the belt, he will be fine.

Otherwise, I have a ZZP 2.6" pulley that requires no machining.. it is yet to be out on tho bc i havn't gotten my injectors yet!

You can get the ZZP 2.6" without machining the snout. You would also need a hub too, the ring won't bolt up with the GM one. If you just want a little more power, get the 2.8" ring. That is a direct bolt on with the GM hub and you can also keep your injectors, tune, and belt.

Thanks everyone for your input...I've decided this pulleyboys 2.8 ring is exactly what I'm looking for. So when I get this thing, all I have to do is take the belt off and bolt on this new 2.8 ring?

You can also use the Mace (I think thats the brand) 2.79" pulley that is running around on ebay for about $65. That will bolt up directly to the GM hub as well.
