Industry Leading Power
With ProCharger technology, reliably adding big horsepower to your engine is a lot easier than you may think. Intercooled ProCharger systems utilize exclusive features and proven technology to deliver reliable 50-85% emissions legal gains in horsepower and torque with stock motors running pump gas. ATI is the only company that has put stock 4.6 2V's and 5.0's into the 11's, and is the only company that guarantees the best performance gains. Nothing else even comes close! For modified street applications, ProCharger technology delivers 10-second ET's with the least amount of engine modifications - and with the supercharger still under warranty. For highly modified applications, ProCharger is the undisputed leader in Ford racing, with eleven national championships in the past 2 years alone. Superior products yield superior results.
The patented SC design eliminates the need for oil lines and punching a hole in the oil pan. Additionally, instead of being forced to utilize heated engine oil or the grease in sealed bearings, SC ProChargers are lubricated with an extremely high quality synthetic oil which is specifically engineered for high speed use, and produces the least frictional heat and parasitic load. The self-contained design not only eliminates the heat that is transferred to a supercharger by engine oil in oil-fed applications, it also avoids the risk of clogged supercharger oil lines, oil drainage problems, or engine oil leakage. By combining an advanced multi-patented supercharger transmission design with the highest quality oil, SC ProChargers produce a larger net power gain because they run cooler and consume less power than comparable oil-fed designs. Both street and strip ProCharger models are also the most durable superchargers available, and are backed by the industry's best warranty coverage.
ATI introduced the industry's first intercooled supercharger system nearly 3 years before its nearest competitor, and is still the only company that offers intercooling as an integrated solution rather than just an after-thought. Intercooled centrifugal supercharging is simply the most sophisticated, reliable and cost effective method for substantially increasing the horsepower and torque of your vehicle. Because intercooling removes heat, increases air/fuel density and allows the use of factory (or close to factory) ignition timing, a well-designed intercooled supercharger system will produce far larger power gains than a non-intercooled supercharger system, especially for fuel-injected motors running pump gas. And after three years of saying that intercooling doesn't work, even our competitors now agree with this.
Compressing Air Creates Heat, Intercooling Removes Heat!
The Fundamental Solution
All non-intercooled superchargers operate with an intake manifold temperature in the general range of 115° - 200° above ambient (outside air) temperature at 8 psi. At the same boost level, an Intercooled ProCharger operates at only 28° above ambient! This tremendous advantage from cooler air is just like the difference between driving your car on a cold winter's day vs the blistering heat of summer! Thats a real advantage that yields real performance. It helps to understand that no supercharger alone will ever begin to match the system efficiency of an intercooled supercharger system. This is simply because compressing air creates heat, as dictated by the laws of physics (Boyle's Gas Law). Even in the case of "perfect compression" (100% adiabatic efficiency, which is physically impossible without an intercooler - see chart), air temperature would increase by approximately 71° at only 8 psi, while the lower (40-80%) efficiencies of all non-intercooled superchargers produce substantially higher temperatures. 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:
Benefits of Intercooling
- Greatly Reduced Intake Temperature
An 85° - 200° drop in air temperature (dependent upon application) results in a more dense, powerful fuel/air charge, greatly reduces exposure to detonation, and virtually eliminates the "power fade" felt in back-to-back runs and extended pulls without intercooling
- 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!
Reliable High Performance
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. Simply locate an engine's compression ratio at the bottom of the chart and trace upwards to determine the maximum reliable boost level. The amount of heat produced (adiabatic effiency) by each supercharging technology is what determines the boost limitation. While gear-driven centrifugal is clearly the superior supercharger technology, it is also clear that the biggest benefit comes from intercooling. These calculations assume moderate timing, 92 octane pump gas, and a good supply of fuel to the cylinders. As mentioned previously, detonation is the single biggest threat to engine reliability. It is heat and detonation that cause blown head gaskets and burned pistons, not boost. Achieving maximum performance from a given engine while avoiding detonation requires the right combination of intake air temperature, timing and fuel quality. For example, without intercooling a stock 5.0 with 9.5:1 compression ratio can only hold 5-6 psi of boost before detonation becomes a problem. The only way to safely run more than 6 psi of boost and still make a meaningful increase in power without an intercooler is by using racing fuel to avoid detonation. Many companies also employ "band-aids" such as ignition retard and larger injectors to run 8-9 psi on pump gas, but the resulting increase in performance is only marginal (since both of these band-aids suboptimize) and detonation is frequently still a problem.
We've all heard of this, but what is it? Detonation, or engine knock, occurs simply when fuel pre-ignites before the piston reaches scheduled spark ignition. This means that a powerful explosion is trying to expand a cylinder chamber that is shrinking in size, attempting to reverse the direction of the piston and the engine. When detonation occurs, the internal pneumatic forces can actually exceed 10x the normal forces acting upon a properly operating high performance engine. Detonation is generally caused by excessive heat, excessive cylinder pressure, improper ignition timing, inadequate fuel octane or a combination of these. Of the previous, excessive heat is usually the culprit. As an engine is modified to generate more power, additional heat is produced. Today's pump gas will only tolerate a finite amount of heat before it pre-ignites and causes detonation. Although forced induction engines usually produce far less heat than comparable naturally aspirated high compression engines, the cylinder temperatures in intercooled engines are radically cooler yet. It is rarely boost that causes detonation, just unnecessary heat. An intercooler is such a natural solution for forced induction, that in almost every OEM application, intercooling is part of the package.
Air vs Water
Accessible Technologies manufactures both air-to-air and air-to-water intercooler systems, and the guidelines for their usage are fairly straightforward.
For automotive street applications, air-to-air technology is easy to install, highly effective, extremely reliable since it has no moving parts, and requires no maintenance. Air-to-water intercooler systems, on the other hand, are much more difficult to install as they contain an intercooler, a separate radiator to cool the water, a water tank, and a pump. But probably the biggest drawback to air-to-water on the street is that this technology requires the addition of ice to match the efficiency of air-to-air technology. Additionally, the requirement of ice and the possibility of pump failure or leakage means that air-to-water is also inherently less reliable.
For race-only applications, air-to-water works well since the need to add ice at the track prior to each run is not a big drawback. The other issues are the same as listed above for street applications, and efficiency will be comparable with the use of ice.
For marine applications, air-to-water is the preferred technology, for three primary reasons. First, the installation of a pump and radiator are no longer required (the lake or ocean is the radiator, and boats already have a water pickup/pump). Second, ice is not required, given the availability of massive amounts of cool lake or ocean water into which heat can be transferred. And finally, since boat engines are typically situated in the rear rather than in the front (like most automobiles), it would be very difficult to find adequate airflow for an air-to-air intercooler in the back of the boat.
A supercharger will decrease the fuel economy of your vehicle, right? WRONG!!
Although roots superchargers have significant parasitic load and do dramatically decrease fuel economy, centrifugal superchargers (like ProCharger) will yield approximately the same fuel economy as normally aspirated engines under normal throttle conditions. This means that after the installation of a ProCharger intercooled supercharger system, if you drive your vehicle in the same manner as you did before the installation, you should see no drop in fuel economy and in some cases customers with heavier vehicles have actually increased their fuel economy because of less frequent downshifts! However, the purpose of the supercharger is to get more air into the engine…and when you add air you must add fuel. So when you stand on the throttle and that impeller starts force-feeding your motor the air it deserves, your fuel system will allow more fuel in to create gobs of Grandma scaring horsepower. It is during those moments when supercharged vehicles see a drop in fuel economy.
To explain further, a supercharged engine operates at a much higher power and efficiency level than a naturally aspirated engine. So why, under normal operating conditions, would making an engine more efficient decrease fuel economy?
ProCharger has a large and ever changing fleet of test vehicles running the streets and race tracks every year. We use these vehicles to test everything you would expect from a company like ProCharger…durability, aesthetics, noise, drivability, power. What you may not expect is that we also collect fuel mileage data on these test mules. A small snapshot of some of our data is below.

The majority of the above data was taken during mostly highway driving on the 2007 Hot Rod Power Tour. As you can imagine, fuel mileage was not the main concern of our drivers when cruising along side the amazing cars that grace the Power Tour. The Dodge Charger fuel mileage was recorded on a recent roundtrip from Kansas City to Tampa, FL. Also, keep in mind that the above vehicles are all stock with the exception of the intercooled ProCharger system. Your fuel mileage may vary depending on your vehicle combination and driving habits.
2001 Chevrolet Silverado customer testimonial after the installation of a P-1SC-1 Intercooled ProCharger system.
“My gas mileage has increased nearly 1 mpg on my annual trip from Michigan to Alabama, from 16.19 mpg naturally aspirated to 17.06 mpg with the ProCharger. Considering these trips are taken during Christmas in the winter with periods of idle time and speeds with the flow of traffic the ProCharger actually helps gas mileage. Add the extra on demand power and the smiles per gallon, the truck makes the trips fun!”
2006 Hemi Ram customer testimonial after the installation of a P-1SC-1 Intercooled ProCharger system.
“I’ve got 34K miles on the supercharger system in the past 9 months, and it’s great. I pass other trucks on hills all the time while towing Bobcats and other heavy loads. And my fuel economy is about the same as it was before, but with a lot more power.”
