Superchargers
Forced induction has created the widest stir amongst enthusiast’s car bar none. For good reason we have been involved with all types of supercharging since our doors opened. With the many varieties  of superchargers and manufacturers, choosing the correct

  system for your application is serious business. It’s not just about a bolt on with an item of this nature. Enormous power gains can be achieved although modest ones can be achieved also. Depending upon your requirements, simply stated, we are an area leader in defining all forms of this power adder. Don’t be left in the dust without finding out how we can help you to make the most appropriate decisions in this matter. Complete systems in a wide price range are available with dedicated customer support and technical service.

Centrifugal Type Supercharging
Centrifugal supercharging compresses the air inside the case of the supercharger using an impeller, then discharges the air out to the engine. This design is similar to turbo charging except centrifugal superchargers don’t use the exhaust to build pressure, they use a belt, driven by the crank pulley to spin the impeller. Centrifugal supercharging is definitely one of the more user-friendly ways to supercharge your engine. Centrifugal superchargers have become the standard for street use and light-duty racing and far out sell all other types of superchargers.

Recommended Usage:
Street Use – Commercial Use – Road Racing – Drag Racing

Positive Points:
1)Lots of flexibility
2)Lower discharge temperatures
3)Great reliability
4)Easy to install

Negative Points:
1)Not as much power at low RPMs as Roots or Screw type superchargers
2) Some parasitic loss of power through turning of the drive belt

Manufacturer Availability:
Paxton – Powerdyne – ProCharger – Vortech – Roots Type Supercharging

The Roots Type Supercharger is the first style supercharger that was ever used and can be dated back to the 1800’s when the Roots brothers designed it as an air conveyor for mine shafts. Roots blowers act like air pumps (not compressors), and in general, Roots blowers have two or three lobe rotor design, depending on the size of the case. Roots blowers will give you positive pressure to your motor from just a crack of the throttle, and will give all that they have to offer at full throttle no matter what rpm of the motor. Roots Type Superchargers may look awesome hanging out of the hood and are great for those looking for drastic power increases at lower rpm’s. Roots blowers are also extremely reliable and require very little maintenance, which is why Ford, GM, Mercedes, Jaguar, and Aston Martin all have featured Roots blowers as original equipment on select high performance vehicles.

Recommended Usage:
Street Use – Towing – Extreme Drag Racing- Show Vehicles

Positive Points:
1)Boosts throughout the entire rpm range, right off idle
2)Highest potential for Gain (a must-have-for-all-out drag racing)
3)Great appearance & stature (most common supercharger type for show vehicles)

Negative Points:
1)Sometimes violent throttle response
2)Lower boost ratings at higher rpm’s
3)Higher than normal discharge temperatures
4)Lengthy installation times

Screw Type Supercharging
Screw type superchargers are derived from the Roots type concept but with vast improvements for street use. Although from the outside, screw type superchargers may look a lot like Roots type superchargers; on the inside you will find a twin-screw design that compresses air unlike Roots type superchargers which pump the air into the motor. Screw type superchargers have an axial-flow design that compresses the air as it moves between the screws to create positive pressure without creating the heat that Roots type superchargers can create. The Screw type supercharger’s ability to produce a dramatic increase of power from idle and through out the rest of the power curve make them a great choice for heavy vehicles, towing or commercial use.

Recommended Usage:
Street Use – Towing – Road Racing – Drag Racing

Positive Points:
1)Great power at low rpm’s (great for towing)
2)Lower discharge temperatures
3)Factory fit & appearance
4)Great reliability

Negative points:
1)The power doesn’t keep climbing in the high rpm’s (power curve is very flat)
2)Challenging to achieve high boost levels or CFM’s
3)Lengthy installation times
