What is Negative Pressure Supercharging?

Negative Pressure Supercharging is a revolutionary new clean burn HTCSI supercharging combustion process that substantially improves torque, acceleration, towing power, fuel efficiency and emissions of street engines

For more details see What is NPS about? and How It Works

Negative Pressure Supercharging does NOT use...
Supercharger air pumps
Turbocharger air pumps
Mechanically complex parts

Computers and complex parts are NOT needed for NPS to work but they may be used to enhance it.

Negative Pressure Supercharging uses a unique combination of mechanically simple parts to supercharge and substantially improve the efficiency of engines...
Compact high velocity Tri-Y Headers
SVT Camshaft
Hot Air Induction housing
Cold Cooling System
Special Ignition Timing

Engine runs HOT with Cold Cooling System, ONLY the coolant passages run cold.

The combination of parts used by Negative Pressure Supercharging produce several highly advanced processes that allow NPS to work...
CHVEG ? Compressed High Velocity Exhaust Gas
SVT ? Synchronised Valve Timing
HPDT ? High Pressure Differential Turbulence
HAI ? Hot Air Induction
HTCSI ? Homogeneous Thermal Charge Spark Ignition combustion

Negative Pressure Supercharging is the SAME as Vacuum Supercharging
Vacuum Supercharging or "heaps more suction" may be easier to understand by the average laymen, but technically the process is Negative Pressure Supercharging. This is because the pressure in the cylinder must be reduced FIRST in order to create a vacuum or suction. Therefore, the more the pressure is reduced in the cylinder, the higher the vacuum or suction, the more air is pulled into the cylinder.

Negative Pressure Supercharging can be easily applied to all engines...
Old or new
Mechanically simple or complex
Carbureted or fuel injected
Petrol, gas or diesel
