Negative Supercharging Kits use a revolutionary new Homogeneous Thermal Charge Spark Ignition (HTCSI) supercharging combustion process that transforms street engines into clean burn fuel efficient torque monsters To find out how it does this see How it Works For details about contents, power and cost of Negative Supercharging Kits select your make of engine Negative Supercharging Kits produce the following benefits with carburetion, gas or fuel injection... • Up to 150% more torque FROM 1000 to 3500 rpm • More peak horsepower at 4500 rpm than higher rpm engines • Faster acceleration using low rpm torque • Massive increase in towing power from idle • 30% more fuel economy • Up to 95% less exhaust emissions • Idles and runs smooth until full throttle is applied • Comes in 7 stages and levels of performance • Comes with a large number of high performance parts NOT included with other performance kits* • Comes with $600-700 FREE head work NOT included with other performance kits • Costs 1/3 the price of conventional supercharging systems** • Bolts-on like conventional parts and is easy to install

* The Negative Supercharging Kit comes with all the Negative Supercharging parts needed to supercharge the engine and a number of heavy duty parts to improve the durability of the engine and transmission to handle the massive increase in torque.


** To produce the same acceleration, low to midrange torque and durability as the Negative Supercharging Kit, it requires using a twin turbocharger system, intercooler and a number of heavy duty engine and transmission parts which cost 3 times more than the Negative Supercharging Kit. Also, a twin turbocharger system reduces fuel economy whereas the Negative Supercharging Kit improves fuel economy.


*** Stage 1 and 2 Kits allow Restorations to supercharge the engine and keep the engine looking original.
