Dodge Viper SRT-10

A client recently purchased a 2008 Dodge Viper SRT-10.  From the factory, a Viper SRT-10 is a powerful car.  We put the Viper on the dyno for a baseline.  The Viper put down 564 rwhp and 539 ft-lbs of torque.


564 rwhp is a lot for most cars, but the owner wanted more power out of his Viper.  Unfortunately, there are currently not a lot of support available for this particular year of Viper.  This is a new platform and is the first mass air flow based drive-by-wire Viper.  This Viper is more efficient than previous generations of Vipers, which will make the task of high horsepower gains difficult.

PSI approached the owner's request from a research and development standpoint.  To increase power from the V10, we decided to increase airflow.



A custom intake was created to eliminate the stock air box.  The custom intake also accommodates the nitrous system's nozzles.

To further improve airflow, PSI added a Belanger header and exhaust setup.

The custom intake, headers, exhaust, and NOS increased the horsepower to 682 rwhp and 782 ft-lbs of torque.

With its drive-by-wire system, the 2008 Dodge Viper SRT-10 is a new platform with a lot of potential.  Our client is interested in the highest performance from his Viper and we look forward to helping him reach his high performance goals.
