ProCharger Race Kits, 135-210+ Crankshaft HP

Most 4.6L 4V ProCharger customers report gains of 135 to 210+ crankshaft horsepower and are able to run 13 to 20 mph faster in the 1/4-mile. That means that with proper traction and good driving, you can take almost two seconds off your ET! Of course, even larger gains are possible with additional bolt-ons or racing fuel.

Both the Serpentine Race Kit and the Cog Race Kit utilize the patented, proven and F-1 Series superchargers.  The Serpentine Race Kit uses the F-1A, a compact, 8-rib shared supercharger drive system, a highly-effective, air-to-air intercooler, OEM-quality mounting brackets, fuel system upgrade, tuning and all necessary supercharger and intercooler tubes for installation onto your 4V Mustang with no major modifications to your car or engine. ProCharger Cog Race Kit uses the F-1A-94, F-1C or F-1R supercharger.

ProCharger supercharger kits feature easy installation and minimal relocation of components.  Additionally,ProCharger Race Kits avoid the issues associated with the complexity and maintenance of an air-to-water-to-air intercooler configuration. ProCharger systems for 4V Mustangs feature a visually appealing, “from the factory” look and come with a standard 3-year warranty on the intercooler and 1-year warranty on the supercharger (Optional 3-year supercharger warranty is available).

Intercooled Supercharging

 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.
 
Detonation
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.
