Supercharge Your Ride
When you're looking for ultimate supercharging performance, reliability and quiet operation look no further than the Paxton NOVI centrifugal supercharger. Using the basic Paxton kit with our custom modifications there is no other supercharger system on the market that can come close to the PROVEN performance of an Underground Supercharger system for your Viper.

How Superchargers Work

What is a supercharger and how does it work?

A supercharger is an air compression device that forces air into an engine. The device allows more air and fuel to be forced into an engine than is possible under normal atmospheric conditions. The mixture of compressed air and fuel in the engine produces a higher compression ratio resulting in more horsepower and torque. While the supercharger is always spinning and moving air, it is not always producing boost in the engine. Boost is a function engine load and RPM. The majority of the time your supercharger will not be producing boost. The supercharger produces boost under high load conditions which may include heavy acceleration, going uphill, passing another vehicle or under towing conditions. Paxton superchargers offer the power you need on demand, the remainder of the time the engine is working just like a normally aspirated engine.

What is the difference between a Paxton Supercharger and a roots type supercharger? A roots-type supercharger is a positive displacement supercharger that forces air into an engine with two rotating, intermeshing rotors. A centrifugal supercharger has an impeller that pulls air through the center and directs the air into a scroll using centrifugal force. The scroll resembles a large blow-dryer with a circular shape and a discharge tube. The air is directed in the scroll, pressurized and forced out of the discharge tube and into the engine. The two types of superchargers have different performance characteristics that have led to several debates on which supercharger is preferable. Proponents of roots blowers argue that more boost is available at lower RPM to provide off the line acceleration. Centrifugal supercharger enthusiasts argue that roots blowers are limited at higher RPMs and can increase air temperature and decrease horsepower. Paxton Superchargers offer significant horsepower at low RPMs with superior mid and high rpm performance. In situations where you demand performance from your vehicle, you are spending most of the time in the mid to high RPM ranges. Paxton is confident in the performance characteristics of its product.
