Lower Pulley (overdrive) replacement on GT500

[BadTony]

Has anyone here done this conversion yet?

What type of results did you yield? Does the 10% in the product name mean that you will get 50 additional RWHP (or more if you are starting with more than 500 RWHP)?

will it need an additional belt tensioner?

 

The Innovators West product coming in at $700 seems a bit spendy ..anyone have any thoughts on this? (why this is or where to get this product at a deep discount?)

Many of us have this. It's essentially part of a Stage III upgrade - generally done with a mono-TB. I wouldn't say it alone give's 10% more hp. It gives 10% more boost. Huge improvement in low-end torque. check my dyno below.

I have it as well. Can not attest to the change you will see by this mod alone as I changed lots of other stuff as well when I had it done. I am running about 18lbs of boost now with headers. I think most with the KB stage 3 and stock exhaust are seeing around 21 lbs boost.

21 lbs of boost - man thats enough to really jump up off the line compared to stocker boost #s

 

That's really got to pull especially in the lower torque sections of the overall power band.
