Welcome To The PSI Blog

The Dodge Viper is an American sports car.  The Viper has a straightfoward design with muscular and aggressive sytling.  Being an American sports car, it has a large displacement V10 under the hood. 

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.
