I've heard that all it really does on its own is move the curves up a little bit so you hit boost quicker, only gives an extra ~1 psi over the stage 2 pulley

Yeah I just did the conversion and stage 2 pulley is 3.06" and stage 3 is 2.99" so .7" smaller. I know its all in what you personally want to do but I'm so glad I decided against the stage 3 pulley and went 2.9".

The guy that owned the car before me ran a 13.9 at race city i believe so it will be interesting to see what a tune and the minor mods will do.

Cheers

I am curious as well.....What tires are you running on the car? I have GM Stage 2 and the updated GM tune on it. My 2.9 polished pulley is sitting on the shelf until I can get a cat-back and exhaust manifold.

Let us know what she runs.
