Intercooled ProCharger systems are the fundamental, OEM solution - because not only is less heat created when the air is compressed, the majority of this heat is actually removed through intercooling. The bottom line is that intercooled boost is substantially more powerful and safe for your engine than hot, non-intercooled boost.

Now that technology has developed to the point that gear-driven superchargers are powerful enough to reliably blow through an intercooler, it simply doesn't make sense not to intercool, especially for fuel injected applications running pump gas. In fact, for high compression engines or continuous duty applications, such as marine or towing, intercooling is absolutely essential for reliability. In basic terms, compressing air creates heat, while intercooling removes heat.

The illustration above may help to further explain the tremendous impact of intercooling upon supercharger system efficiency and engine intake temperatures. Full Timing This reduction in temperature allows you to run factory or close to factory timing, and avoids the substantial horsepower loss inflicted by excessively retarded ignition timing.

More Low-End Boost and Horsepower The intercooler also acts as a passive wastegate, flattening the boost curve at higher rpm's and allowing more boost to be dialed in at lower rpm's. An Expanded Power Band Full timing and forced induction keep the engine pulling hard to the redline. More Boost Not only will you experience the above benefits at any boost level, you can also safely run substantially more boost when intercooled!

Clearly, the only type of performance that matters is reliable performance, and detonation is the single biggest threat to engine reliability. The boost range for reliable performance, without detonation, can be determined by looking at the type of supercharger technology being considered, and the compression ratio of the motor. With a lower compression ratio, an engine can safely handle more boost, everything else being equal.

Similarly, if the temperature of the compressed air is lower, an engine will have a much higher detonation threshold the point at which fuel ignites without a spark , and will be able to safely handle more boost. The chart below helps to illustrate how the overall efficiency of the entire supercharger system can be increased by both leading edge supercharger efficiency and the use of intercooling. Performance engine's stress and prematurely wear the engine's oil requiring an oil cooler and an intercooler.

Many parts on these engines are unique and reinforced to withstand these additional pressures. Study Tips Feedback. The reason aftercoolers are more effective in cooling the air charge is because water is a much better conductor of heat than air — in fact water conducts 4 times as much heat as air! The obvious drawback is that with time, the water will heat up to the temperature of the air passing through it, and its ability to cool incoming air goes away.

Some aftercoolers, however, use a small radiator to cool the water that runs through the system, making them ideal for street use as well as racing.

For drag racing applications aftercoolers packed with ice work very well because they only need to work for around ten seconds or so hopefully before you shut down and head to the victory podium. Obviously, intercoolers only work with supercharged or turbocharged vehicles where there is a substantial difference in temperature between the air entering the engine and the cooling medium the intercooler.

Because superchargers heat up the air significantly as they compress it, it is possible for there to be a very large temperature difference between the intercooler ambient air temperature — 80F degrees or so and the compressed air F — F degrees. Superchargers with higher boost will create a hotter discharge, so as you increase your boost, the effects of the intercooler become more and more noticeable. In general we would not recommend intercoolers on supercharged engines with less than psi of boost, as the benefits will not be substantial.

Essentially, run an intercooler when only when you running peak boost i.
