ProCharger - the Next Generation Supercharger

ProCharger supercharger

Imagine a bolt-on device that combines the simplicity of a turbo, with the instant, on-demand power delivery of a supercharger - that's ProCharger. No special exhaust manifolding of the conventional turbo, and none of the air-pumping inefficiencies of the conventional Rootes blower. Best of all, the ProCharger is self-contained, and comes with its own lubrication system. Depending on the engine design and the installation, ProCharger can deliver anything between 55 to 100 per cent more power - and that's on standard pump fuel too.

So how's it done? Well, the ProCharger is an engine-driven centrifugal compressor and is matched to an air-to-air intercooler. However, because the ProCharger delivers its boost in line with engine speed, you don't have to wait for an exhaust turbine to spin up before the power starts coming through to the flywheel. And, unlike traditional lobe-type Rootes supercharging, the increase in air/fuel being forced into the cylinders is more gradual, rather than arriving as a sudden 'shock' load that can lead to detonation and blow holes in pistons. Bad enough on a road car - but on the track, something that can put you right out of competition. That's why both turbo and supercharged engines usually have lower compression ratios to start with - even though it means that any forced induction has to play 'catch-up' in the early part of the rev range where a normally aspirated engine would already be coming onto the power curve.

The ProCharger's use of an intercooler has another benefit too. Reducing the air temperature increases its density. The denser the air becomes, the more thoroughly the fuel mixes in with the available oxygen, leading to a far more efficient burn that is automatically cooler to start with. So excess heat, that other contributor to detonation, can be kept better in check. So the ProCharger has benefits of no modification to the exhaust manifold or oil system, it delivers a cooler charge which means that engine modifications (e.g. lower compression ratio) may not be required and above all it delivers significant increases in power and torque throughout the rev range whilst running on standard pump fuel.

Self Contained Bolt-on Power

The self-contained SC series of ProCharger models are the first and only gear-driven centrifugal superchargers to feature self-lubrication, and contain the industryís 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 model 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 ProChargerís 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.
