Performance Improvements

Negative Supercharging produces the combined performance advantages of a race car, family car and truck

Race Car

Violent acceleration of a race car

Smooth idle, acceleration and fuel economy of a family car


Massive towing power of a truck

Plus many more performance advantages

  • Peak torque from idle
  • 2 times more torque from idle to midrange during full throttle
  • 3 times more torque from idle to midrange during part throttle
  • Violent launch from idle during full throttle
  • Smooth acceleration during part throttle
  • Extremely responsive at any throttle position
  • Effortless acceleration in 3rd gear from a standing start
  • Effortless acceleration using low rpm
  • Low and smooth exhaust note with a deep thump of a big block during idle and cruising
  • Powerful growl of a race car during full throttle
  • Easy starting
  • Makes carbureted engines run as smooth as fuel injected engines
  • Allows carbureted engines to be driven immediately from a cold start like fuel injected engines
  • Allows carbureted engines to idle all day in heavy traffic and not foul the plugs
  • Allows full throttle acceleration from a dead cold start using a carburetor (not recommended even though possible)
  • More torque and horsepower the hotter the outside air temperature
  • Hot air from around the exhaust manifold is drawn into the engine to produce more power
  • Water reaches operating temperature in half the normal time
  • Water runs cold at half the normal operating temperature of standard and high rpm engines
  • Water runs cold while towing in hot weather and heavy traffic
  • Eliminates overheating
  • More manifold vacuum
  • More fuel economy
  • Less emissions
  • Lower maintenance and running costs
  • 1/3 the price of conventional supercharging
  • More performance per dollar than any other technology currently available
