Negative Pressure Supercharging transforms standard and performance engines into a Torque Monster Sleeper that produces such a huge increase in torque from idle to 4500 rpm that the vehicle...

•  Accelerates fast like a race car
•  Pulls hard from idle like a truck
•  Idles smooth like a family car
•  Increases fuel economy by 30-50%
•  Reduces emissions to ultra low

Negative Pressure Supercharging makes the engine idle and run so smoothly with a carburetor at part throttle that it feels like a new fuel injected family car. It's only when full throttle is applied anywhere from idle to 3500 rpm that all hell breaks loose.

Negative Pressure Supercharging can be applied to a wide range of vehicles from...

  • Muscle Cars
  • Vintage Cars
  • New Cars
  • Hotrods
  • Pickups
  • RV's
  • Vans
  • Trucks
  • Motorcycles
  • Boats
  • Propeller Planes
  • Buses
  • Tractors
  • Tow Trucks
  • Agriculture
  • Industrial
Negative Pressure Supercharging produces the ultimate street performance engine in acceleration, towing power, fuel economy, emissions, cost and maintenance...
  • Fast acceleration using low rpm torque instead of high rpm horsepower
  • Smooth idle and acceleration whether the engine is carbureted or fuel injected
  • Massive towing power from idle to 3500 rpm
  • 30-50% more fuel economy than standard or high rpm engines
  • 50-70% more fuel economy than engines with supercharger air pumps
  • 1/3 the price of conventional supercharger air pump systems
  • 1/2 the price of high rpm engines
  • Less wear and tear on engine parts than high rpm engines
  • Same low maintenance as standard factory engines
  • Lower emissions than standard factory engines
  • Much lower emissions than high rpm or supercharged engines
