Seems everyone added them with other parts or say they "feel" like they added power. Anyone have before/after dyno #'s to verify actual gains?

 

No one???

 

Anyone?

 

I was curious about the same question....... I installed pullies recently but also had 4.10s installed since my last dyno run. Previously I had asked what kind of "loss" would the 4.10s cost me on the dyno, because I wanted to gauge what impact the pullies had. I was at 296/316 before the pullies and gears, and I'm hoping that with the pullies and gears installed, I can get over 300. Once I get back on the dyno, I'll post back.

I've heard 10 rwhp from my tuner.

 

I have heard all the claims, but I want to see hard #'s.
Tom-post back when you get your results...
