He have completed our 2.57 prototype pulley for the 2009 press-on style roushcharger. These images are showing the pulley in raw 6061 billet form. The completed product will be highly polished and coated with a clear anodize.
This will increase your boost level from stock 5.5-6 psi to a new 7-9 psi.
We will have before and after dyno numbers tonight. Along with video and viewable dyno sheets.

After is not complete yet


However, I will say... So far, the car has made 401rwhp/381 rwtq

This car came to us w/ 100% stock exhaust - stock cats and stock mufflers...etc...

It had a Steeda CAI and a SCT tuner.

So, these numbers are true numbers... We will post SAE as well as STD.

^^^ Great numbers for just a simple pulley upgrade.


Keep in mind folks, this was on a stock car.

Stock exhaust manifold, stock catted mid-pipe, stock mufflers... STOCK
