At PSI, we use a system approach to racing by under standing that everything must be “Dialed In” to race at the Championship level. Using only the best equipment to achieve this level of racing is half the battle. This is why we design, build and supply a host of related parts to create an integrated system. To complete the package, we also provide the most comprehensive technical support for every product supplied by PSI.
PSI revolutionized racing by taking a fresh look at the old ideas and placing them in a new light. Our Goal is to supply state of the art industry leading products that ensure that our customers have the best products to compete with and win.
The Psi 206-D is the first blower to power blown alcohol cars to over 270 mph in 5.2 seconds elapsed time. In fact, everywhere a PSI turns up it makes an unforgettable impression, setting and breaking records in Blown Alcohol Funny Car, Alcohol Dragster, Blown Gas Hydro, Blown Alcohol Hydro, Australian Pro Mod, and Bonneville. The 206-D is the first supercharger to be S.F.I. certified assuring you get safety, performance and durability unavailable to racers - until now.
The PSI 206-D is a positive-displacement screw compression supercharger. It is belt driven, and has instant throttle response. The unique feature of a screw supercharger is its internal compression. Its rotors compress the air as they turn, delivering cool, pressurized air to the intake manifold. Besides its phenomenal air delivery (60+ pounds of boost), it weighs about 40 pounds less than its closest competition. It has magnesium housing and billet aluminum rotors.
Designed for the special requirements of competition, it has significant advantages over all other blowers:
Instantaneous throttle response: The rotors have less leakage than any other supercharger resulting in full boost sooner Cooler manifold air extends crank and piston life and reduces detonation
Rotors flex less reducing tip strip wear and leakage
Higher efficiency means more engine power at all engine speeds
Staggerless fuel distribution makes tuning simpler and maximizes each cylinder's performance
Lower cost of ownership: The PSI's durability and reliability results in benificial effect on engine parts
Superior air delivery: Power to spare without high revving your engine
Timing. PSI rotors don't go out of time
R & D: Drag racing is a game of pushing the limits, so we are constantly redesigning our products
