Pulley size is now a spec

davidhuff · 10-23-2009, 05:30 PM

Ford Racing knew the stock supercharger pulley on the cobra jet was going to be a issue and this is what they are going to do:
2007 cobra jet has a 2.3L eaton supercharger
2010 cobra jet has a 3.4L whipple supercharger and this supercharger is bad *** and will move a ton of air!

My point Dave is along the lines that you increased the supercharger size almost 50% - did you increase HP by 50%? Don't think so. The Whipple screws are not as efficient as the TVS, they have to be much larger to realize the airflow and HP increases like you have seen.

The 2010 CJ will be SS Only

The 2010 CJ should be introduced soon, however the cars are available with multiple engine and transmission options including a Super Stock version. More info on the Stocker combos along with body in white kits should be available in Vegas at the Thursday nite Ford meeting (Tasca tent) and again at SEMA.

No it did not increase my HP by 50% but I did make 733 RWHP on pump gas with a 3.25 supercharger pulley and 72# fuel injectors.
