Viper - Stage One heads, CEM camshafts

 Exclusive new product!
CNC machined billet main caps for Dodge Viper

Report date - February 20, 2008

With your CM Stage One heads installed, as well as Harold Hallam's exclusive CM camshafts, a cold air intake and a set of headers, we put the car on the chassis dyno earlier this morning. The results were quite satisfying, to say the least.

Using a stock Gen III Viper as a benchmark (428.48 rwhp and 464.72 ft/lbs of torque), we have added more than 133 horsepower to the back wheels, as well as another 75 ft/lbs of torque. Your car actually produced 561.73 rear wheel horsepower and 539.01 ft/lbs of torque. The Dyno sheet is reproduced for you below.


Report date - February 15, 2008

We have now completed the rebuild of your Viper cylinder heads and should have them installed back in the car early next week.
