It is the looks and power of the Viper that have made it a popular car for many of our clients.

The photo above just shows a few of the Vipers that we have at our shop.  We have worked on every generation of Viper.  Recently, a client brought in his track prepped Viper to have the clutch replaced for the upcoming season.  We did some work on this same Viper the previous year. 

Not all our clients race their Vipers, but many daily drive them.  For these cars, a new header and exhaust system are popular additions.  They provide an increase to power output, and a very noticable difference in the sound.  The sound and feel is what makes driving these cars special. 

Here is a video of one of the Vipers on the dyno.

This Viper had a set of Bellanger headers and exhaust installed. The headers and exhaust made this Viper sound even better than it already did.  The Viper also received a custom PSI intake system with wet nitrous injection.  This Viper put down 678 whp and 779 ft-lbs of torque. 

For some clients, 1000whp is the goal for their Vipers.  At this point, forced induction is needed to push the V10 even further.  These high horsepower goals are reached through the assistance of a supercharger or twin turbos, and our clients have opted from both. 

This twin-turbo Viper produces over 1000whp on pump gas with water/methanol injection.

The Viper V10 has not only graced the engine bays of Vipers but also of the Dodge Ram SRT-10′s.  At one time, we had both a supercharged and twin-turbocharged Ram SRT-10′s and both were making over 1000whp. 

We also must really like the Viper because our video game system is a Dodge Viper. 

We took the back section of a Viper that we purchased for the engine and turned it into a gaming system.  It currently features a Playstation 3 with a Logitech steering wheel.  It is hooked up to a 3D television to give it a little more realistic feel.  Our current game of choice is Gran Turismo 5.  Whenever we are not working on cars, we like to race with them in our Viper. 

Some might be wondering what car is going to be powered by the engine from our game system.  That project is currently being worked on and more details will be released in the future.  Check back here for more about the Vipers and other cars we work on everyday.

The Viper was beaten by another vehicle powered by a Viper V10.  This 2005 twin-turbo Dodge Ram SRT-10 put down 1260 whp and 1192 ft-lbs of torque.  With a race gas map, the truck was able to make this much power from the V10 with the help of two GT42 turbos.

We will just have to wait and see how long this Twin-Turbo Ram SRT-10 stays at the top.

The ones that are being worked on are forced induction vehicles.  The stock Viper V10 was just not enough power.

This Ram SRT-10 from about a month ago put down 900+ whp with the help of a ProCharger.  

As I am writing this, there is one with twin-turbos and one with a ProCharger.  Both of these trucks put down over 1000 whp.

This is a video of the twin-turbo Ram SRT-10.  To get this Ram SRT-10 to run right, a John Reed Racing PNP AEM EMS was installed.  This twin-turbo Ram SRT-10 currently puts down 1000+ whp and 1000+ ft-lbs of torque on pump gas tune by John Reed.

This Ram SRT-10 is a little different then most. Attached to the V10 is a 5.4 ratio ProCharger. With forced induction, this truck was able to make well over the stock 500 bhp. With the AEM EMS in control, John Reed was able to put down over 900 whp with this setup.

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.
