Impulse Crate Engines 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 Impulse Crate Engines select your make of engine Impulse Crate Engines 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 • Come in 3 stages and levels of performance • Comes with a large number of high performance parts* • Comes with $4,200 of high performance parts NOT included with other crate engines • Comes with $700 FREE head work NOT included with other crate engines • Comes with 8.5:1 compression ratio suitable with low octane fuel • Costs 30% less than naturally aspirated crate engines • Costs 1/2 the price of supercharged crate engines**

* The Impulse Crate Engine comes with all the parts of the Negative Supercharging Kit needed to supercharge the engine and a wide range 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 Impulse Crate Engine, it requires using a crate engine with a twin turbocharger system, intercooler and a wide range of heavy duty engine and transmission parts which cost 2 times more than the Impulse Crate Engine. Also, a twin turbocharger system reduces fuel economy whereas the Impulse Crate Engine improves fuel economy.
