It is this approach that allows ATI to offer exclusive features which improve both the performance and reliability of ProCharger systems relative to other products. For example, it is simply an undisputed fact that lowering charge air temperatures will substantially improve both performance and engine longevity, and ATI provides the coolest intake charge air temperatures in the industry by a wide margin. Similarly, by using CNC machining and nearly indestructable 7075 T-6 aircraft aluminum to produce the largest and strongest impellers in the industry, ATI is able to again improve both performance and reliability. ProChargers are the only centrifugal superchargers to incorporate billet impellers in production models, and this is another example of ATI’s technical leadership. This quality and durability in turn allows customers to have further peace of mind knowing that ProCharger superchargers are also backed by the best warranty in the industry, for the highest boost and power levels. For more information on the physics behind supercharging and the advantages of ProCharger technology, see the ProCharger Technology page.

In addition to absolutely unmatched performance and reliability, ProCharger supercharger kits also offer the following benefits to customers:

SUPERCHARGER QUALITY FROM THE INNOVATOR AND LEADER

ATI’s self-contained (SC) ProCharger models are the first and only gear-driven centrifugal superchargers to feature self-lubrication, and contain the industry’s most advanced technology. In addition to the patented self-contained oiling design, SC ProChargers also feature the highest step-up ratio, exclusive billet impellers, and the industry’s only billet gearcases for superior rigidity, sealing and appearance. These proven self-contained ProChargers were designed specifically for internal lubrication and have become the industry standard.

The best-selling P-1SC-1 shares many of the design elements which deliver the record-setting durability and performance of ProCharger competition superchargers, and is also quiet and street legal. With their rugged design, these ProChargers are the only self-contained superchargers durable enough to be backed with a 3 year warranty and powerful enough to harness the benefits of intercooling.

The patented SC design eliminates the need for oil lines and punching a hole in the oil pan, thanks to an exclusive oil pump. This pump aerates the oil to create the oil mist lubrication required for the ProCharger’s precision bearings and gears. This oil pump (aeration pump) does not require priming at start-up, and oil changes are required only every 6,000 miles. Additionally, instead of being forced to utilize 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 also eliminates the heat that is transferred to a supercharger by engine oil in oil-fed applications, and avoids the risk of clogged supercharger oil lines, oil drainage problems, or engine oil leakage.

By combining advanced 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. SC ProChargers also feature an internal step-up ratio of 4.10:1 for improved belt tracking and traction, and maximum low-rpm boost and power.

ProCharger is also the first and only manufacturer to offer the choice of standard or helical gearset for noise reduction on the P-1SC-1 and the D-1SC supercharger models.

AIR-TO-AIR ADVANTAGE

It’s a simple fact of physics: cooler air makes more power. On street driven vehicles, air-to-air intercooling is a natural fit because it locates the intercooler at the front of the vehicle where it is exposed to a constant supply of cooling airflow. Experts agree that air-to-air inherently provides better cooling and reliability than air-to-water intercoolers for street use. Engineered with large-volume air plenums, ProCharger’s air-to-air intercoolers utilize a highly effective and extremely durable bar and plate intercooler core design that provides large surface areas for superior levels of heat dispersion.

Air-to-air intercooling is a highly effective one step process and represents a fundamental ProCharger advantage. Compressed air enters one side of the intercooler, making its way into the bar and plate core. Once in the core, the compressed air is cooled by the airflow moving through the passages or fins of the intercooler. Next, this cooler, denser air is routed into the throttle body and into the engine. ProCharger intercoolers typically feature best in class effectiveness of 70-80%.

On the other hand, air-to-water intercooler systems use a complex arrangement of intercooler cores, hoses, fittings, a coolant pump, electrical connections and yes, a secondary air-to-air heat exchanger. In street applications, an air-to-water intercooler is in fact an air-to-water-to-air system.

With air-to-water-to-air, heat is first removed from the air by the water circulating through the intercooler. This heated water is then pumped through a radiator, and returned to a tank. The overall system performance is “watered down” because its effectiveness is a diminishing function of the individual effectiveness of each heat exchanger. For example, 65% intercooler effectiveness and 60% radiator effectiveness produce a combined effectiveness of only 49%. “Two step” cooling is, by design, inherently less effective. Typically exposed to heat soak from the engine, air-to-water-to-air intercoolers are complex, difficult to install, and less reliable than air-to-air intercooling.

HELICAL GEARS = QUIETER PERFORMANCE

For those wanting to have less noise when driving, our helical gearset makes a lot of sense.  These gears are machined of high quality, hardened steel ensuring many miles of reliable, smooth performance.  Helical gearsets are ideal for those Durangos with a stock or OEM exhaust.

HELICAL SUPERCHARGER GEARSET OPTION FOR NOISE REDUCTION

Since introducing the industry’s first self-contained, gear driven supercharger back in 2000, ProCharger’s design has proven itself over millions of miles and countless passes down the drag strip. With it’s billet aluminum transmission case, industry leading step-up ratio, high-efficiency compressor and aerospace billet impeller designs, ProCharger’s lineup of high-efficiency superchargers have become the standard by which others are measured.

Now, ProCharger is extending our lead even further with the introduction of a helical gearset for a significant reduction in supercharger sound levels. This new helical gearset, along with a few other internal design modifications, results in a supercharger with all the same power potential as the standard blower, but at reduced sound levels, especially at engine idle speeds. With this new offering ProCharger becomes the first and only supercharger manufacturer to offer customers a choice of gearset design and noise level, as the standard design continues to be available.

We know that many ProCharger owners want the world to know, and hear, their new-found ProCharger horsepower. However, for those owners who want a more stealthy horsepower profile, the new helical gearset option provides that choice. Additionally, not only is ProCharger the only supercharger manufacturer to offer customers their choice of sound levels, ProCharger is the only centrifugal manufacturer to offer noise reduction on it’s “upgraded”, highest flowing street/strip model.

The new helical gearset is available on ProCharger P-1SC, P-1SC-1 and D-1SC supercharger models and must be specified at the original time of order.

BYPASS VALVES  – SURGE VALVES FOR STREET AND RACE APPLICATIONS

WHY ARE BYPASS VALVES IMPORTANT?

For supercharging applications, surge occurs when excessive boost or pressure spikes as a result of a sudden throttle blade closing, which can cause severe damage to a supercharger and is why we mandate all ProCharger supercharger installations use a bypass valve.

A SIMPLE WAY TO LOOK AT OUR OFFERINGS IS BASED ON YOUR ENGINE’S HORSEPOWER OUTPUT LEVEL:

700 HP OR LESS – PROFLOW OR BULLET BYPASS VALVE IS RECOMMENDED, DEPENDING ON PREFERENCE

ProFlow Valve: The ProFlow valve is the standard surge valve option for our street supercharger systems and kits. Compact in size. It can be fitted into tight spots when space is limited. Its butterfly valve is extremely durable and reliable, and this design creates a straight airflow path which achieves excellent flow for its size. The ProFlow valve can also be paired with a small air filter to minimize noise.

Bullet Valve: This surge valve’s compact design also makes it fit easily in tight spaces. It comes in both an open and closed format. The closed format allows you to recirculate air back into the system, or instead to run to an air filter to minimize noise.

701-1200 HP – RACE OPEN BYPASS VALVE IS RECOMMENDED

Race Valve: This is the industry leading surge valve for both street and race applications. The larger valve diameter is designed for high flow applications.

1201-3500 HP – PRORACE BYPASS VALVE IS RECOMMENDED

ProRace Valve: One ProRace Valve outflows any other single valve on the market and is our highest-hp bypass valve option. This massive flow capacity comes from a piston style valve design (patent pending) that allows for a significant increase in curtain area over traditional style valves, while still fitting into a reasonably sized package. It also incorporates a v-band clamp for an easy install.

OPEN VS. CLOSED BYPASS VALVES

Open – Vents to atmosphere and creates a distinctive “whoosh,” when the throttle blade suddenly closes, which a lot of people enjoy the sound.

Closed – Vents to an external air filter or an internal tube for rerouting excess boost pressure back upstream of supercharger for a more quiet and subtle sound.  More ideal for street applications where someone wants more of a silent or stealth operation of the supercharger.

For street applications, our complete systems and tuner kits come with the proper bypass valve based on the vehicle’s horsepower output level so, no need to worry about the right one. However, we do offer upgrade options for our Systems and Tuner Kits with our Race bypass valve family for those seeking a little more sound or those that like the cool look of the anodized finish of our Race bypass valves.

BYPASS VALVES ARE NOT WASTE GATE RELIEF VALVES

Contrary to most perceptions a bypass valve is designed to relieve boost/pressure when the throttle blade is closed.  Conditions such as idle, during shifts, and backing off throttle during tire slip conditions are very important to have a bypass valve.  A bypass valve utilizes a vacuum line port behind the throttle blade and vents when detecting an immediate change in pressure. Bypass valves are different from a wastegate relief valve, which operates as a pressure relief valve and opens or vents excess pressure when a certain pressure is achieved.

WOULD YOU EVER WANT TO INSTALL A WASTE GATE RELIEF VALVE WITH A PROCHARGER SUPERCHARGER?

The correct answer is no. Our superchargers are designed to provide maximum boost and efficiency at the maximum engine rpm and by adding a wastegate relief valve to vent that boost is defeating the whole purpose of having an efficient ProCharger supercharger.  Proper supercharger pulley size and knowing how much boost your engine can handle at its rated max rpm are the keys to success with a proper ProCharger setup.

It’s true, intercoolers play a huge roll in creating high HP while also maintaining engine reliability in a supercharger system. However, this important part is often never mentioned when comparing supercharger systems. In this blog we will cover the items that set the ProCharger intercoolers apart from the rest, to help illustrate what gives our supercharger systems the coolest air charge temperatures, and thus the largest, most reliable power gains available.

Design

For starters, ProCharger uses the highly effective (and durable) “Bar and Plate” design for street/strip intercooler cores-the core itself is not only engineered to be of the proper size for the application, but also the core “spacing” of the bars and plates to ensure proper airflow flow to fluid systems behind the intercooler (IE: Radiator/Condenser).

One of the often overlooked aspects of an intercooler is weight. We all know that if its lighter, its faster, so with that in mind ProCharger engineers design light weight stamped sheet metal aluminum end tanks for our intercoolers, instead of commonly used (heavy) cast aluminum air-to-air units – not to mention the weight of a pump, secondary heat exchanger, coolant reservoir and coolant of an air-to-water-to-air intercooler system.

ProCharger not only tests to ensure the pressure drop across the core’s flow path is at its absolute lowest, but also checks for proper temperature reduction between inlet and outlet. When intercoolers are being tested for their effectiveness, we are looking for the coolest air charge possible, but we also want to make sure the supercharger isn’t working to hard to “push” air through the core itself.

Starting with the impeller you will notice that the “X” impeller is a bit taller and a more swept blade design.

Internally the volute pocket has also been changed, as well as a single rib on the discharge outlet.

Externally the volute is drastically different, however still features a compact 9.0″ diameter footprint.
