PROCHARGER SUPERCHARGER TECHNOLOGY

Pioneered Self-Contained Oil Supply

ProCharger introduced the industry’s first self-contained, gear-driven centrifugal supercharger. Since then, this patented and proven self-contained design has become the standard by which other superchargers are measured. By freeing the supercharger of the engine’s oil supply, you don’t have to punch a hole in your oil pan, motor oil contaminants are eliminated, and our units work great for dry sump or custom applications where blower locations would be limited by motor oil drain back. You also avoid the risk of clogged oil feed lines and oil drainage problems. Testing has shown self-contained superchargers run cooler than those fed by engine oil. Independence from engine oil allows a ProCharger to operate seamlessly under extreme conditions, like arctic cold and desert heat.

The Secret to Our Oiling System Success…

At the heart of the ProCharger self-contained design is a simple, but highly effective oil aerator that creates an effective oil mist lubrication for the precision bearings and gears. This design does not require priming at start-up, and oil changes are only required every 6,000 miles.

While it is common to have intercooling on supercharging applications today, that was not the case when ProCharger launched its first products in 1994. Cooler air means more power potential from the engine, so from the beginning ProCharger sought out air-to-air intercooling as a way to lower intake air temps. It’s a compliment to see that our principles and practices have inspired other supercharger manufacturers to follow suit. Learn more about ProCharger’s intercooler designs and options.

The First to Use Billet…Everywhere

Using state-of-the-art, five-axis CNC machines, ProCharger crafts our superchargers from billet everywhere we can. ProCharger’s proprietary impeller designs are crafted from aircraft-grade 7075 T-6 aluminum alloy for tremendous strength and performance.
The brackets, serpentine drive pulley, and supercharger gearcase are made from billet 6061 aluminum. With a higher strength to weight ratio, our superchargers are lighter and can produce higher pressure, flow more air and, in turn, produce more power.

Why are ProCharger parts machined from aerospace-quality aluminum billet?

To give you more boost, airflow, and power! Billet components offer strength unmatched by more commonly used castings. The material tensile strength for most aluminum castings is 32,000-36,000 psi as compared to the 7075 T-6 alloy used in ProChargers which is 83,000 psi, allowing for greater weight savings and tighter tolerances to yield the largest power gains.

What other benefits do billet parts offer?

By using billet, ProCharger is able to test and evaluate new design shapes and is not confined to a basic design that may only be “trimmed” in an attempt to meet the needs of a given application. Billet components also avoid common issues seen in castings, like density variations, porosity, and inclusions.

Proven by dealers, racers, and vehicle owners around the world, no other form of aftermarket power-adder provides the combination of power, reliability, ease of installation and maintenance, engine safety, and cool operation of a ProCharger. Let’s take a look at why the other power-enhancing options are inferior to a ProCharger.

Positive Displacement Blowers
Centrifugal superchargers offer substantially higher
adiabatic efficiencies than their positive-displacement (PD)
counterparts. PD blowers are located on top or nestled
in the “V” of the engine, placing them in a very hot, harsh
environment, which results in significantly hotter charge
air temperatures. To cope with these high charge air
temperatures, PD blowers must be tuned extremely rich
with less timing, which reduces the vehicle’s fuel efficiency,
drivability, power, and engine longevity.

Turbochargers

Turbo systems’ initial cost and complexity make them less practical for everyday street driving. Because a turbo relies on hot engine exhaust to create power, they also create high exhaust temperatures and back pressure, high charge air temperatures and are subject to “lag” that degrades their real-world driving performance. Additionally, turbos require engine oil feed and return lines for lubrication and due to extreme heat, increases the thermal breakdown of your engine’s oil.

Nitrous Oxide

Initially, nitrous may look like a bargain, but a review of the facts reveals otherwise. Nitrous oxide accelerates the combustion rate, which in turn increases peak cylinder pressures. This combination greatly increases the probability of piston-melting pre-detonation. This rapid increase in cylinder pressure also increases the load placed on internal engine components. Additionally, nitrous oxide adds the expense and hassle of constantly having to refill bottles and is not always available when you need it.
