Blower Intercoolers

The concept of intercooling has been around for many years. Intercooling refers to the use of a heat exchanger to reduce the engine inlet air/fuel temperature thereby increasing the AIR DENSITY. Air density refers to the amount of oxygen present in each cubic foot of air consumed by the engine. When the air is compressed by the supercharger, the air is heated. The heated air expands or it takes up more space. Cooler air takes up less space. Therefore by cooling, more air (oxygen) can be delivered to the engine. More air means more fuel, more fuel means more horsepower.

The net horsepower gain by supercharging an engine can be substantially increased by cooling the boosted air charge delivered by the supercharger. Independent testing has shown increases of 100 horsepower or more with the use of an intercooler.

These intercoolers are designed to be placed between the intake manifold and the blower. The intercooler assembly will increase the overall height of the blower system by four inches. Installation requires longer blower mounting studs, longer belts and possibly different blower pulleys. Obviously a cool water source is also required. The cooler the water going into the intercooler, the more gain in horsepower.

There are two ways to plumb the water system for an intercooler. The most efficient method is designed for marine systems only (see diagram at right). The second method of plumbing incorporates the engine cooling system into the intercooling plumbing system.

the blower shop logoIf you are seeking to purchase a new intercooler for not only its added horsepower but its great aggressive appearance and only the very best will do. Look no further! Since the Blower Shop has introduced its all new "Billet" intercooler that's CNC machined from one massive stock of 6061-T6 aluminum comes this show piece but they didn't stop there they used the latest in aircraft technology intercooling to develop one of the best performing intercoolers anywhere at any price. But that's just it, they did all of this and yet still made it affordable and a great value.

whipple logoWhipple Superchargers continuing strive for excellence and technological advancements have now developed a new line of incredibly efficient line of low profile intercoolers that are truly state-of-the-art. The "Whipple Cooler: intercoolers were designed and built by Garrett® specifically for Whipple Superchargers. Garrett® is one of the world's largest and most technologically advanced intercooler manufacturers. The "Whipple Cooler" intercoolers feature Garrett's® new space age technology that combines the virtually indestructible material know as Cupronickel with the very effective metal, copper. The Cupronickel is used for all the water tanks and passageways while the air fins are made of pure cooper for incredible cooling efficiency. Cupronickel will never corrode or biofoul such as aluminum-type coolers as well as having a much higher temperature range (than aluminum) for extreme situations. The copper fins offer almost twice the cooling efficiency over the traditional aluminum-type cores, which allows for a much cooler air charger. The substantial temperature decrease can offer you far more achievable power and at the same time, greater durability and reliability.

Water Pressure Relief Valve
water pressure relief valve

This spring loaded adjustable water pressure relief valve is a must in any intercooler application. It allows you to shut water off to the intercooler at engine idle speed (which is a must) yet lets water flow freely once water pressure and engine rpm increase. This unit also acts as a safety relief keep high pressure water pressure spikes from damaging your intercooler.
