This is the latest project that we have been working with John Reed Racing on.  It is a turbocharged Polaris RZR.  We handled design and fabrication of the turbo kit and John Reed handled the wiring and tuning.

On The Dyno, we have a 2010 Chevrolet Corvette ZR-1.  A stock ZR-1 is a pretty impressive car with its supercharged LS9.  However, this is no ordinary ZR-1 but has had a few custom upgrades.

Turbo Mini Cooper - 001

One of our clients is an avid autocross driver and competes in his Mini Cooper S. For the past several seasons, he has been running a modified supercharged setup. This past year, John Reed installed and tuned a ViPEC V88.

Nowdays, we have become dependent on fuel.  We drive to and from work, and in the process use a lot of fuel.  Getting the fuel from your tank to the engine is also very important.  From the factory, stock vehicles have this fuel movement taken care of.  On heavily modified vehicles, upgrading the fuel system is often a necessity.  Take this truck for an example,

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.
