2005-2008 Magnum 5.7L R/T HO ProCharger Supercharger (Complete Kit) ProCharger
Why ProCharger Superchargers for your HEMI powered Car or Truck?
ProCharger superchargers offer some of the most reliable, and efficient supercharges on the market today. Think of a turbo without the lag. Like turbos, ProChargers utilize centrifugal forces to compress air, but unlike turbos they are driven by the engine’s crankshaft not its exhaust flow. The result is a liner, predictable power curve, with very streetable manners. Another advantage is ProChargers are able to maintain much cooler intake air temperatures. Because the system’s intercooler has greater flexibility in mounting locations, engineers are able to optimize the charge cooling system. In many cases ProCharger’s massive 3 core intercooler is mounted ahead of the radiator, directly in the cool air stream at the front of the vehicle. Lower intake air temperatures translate into a denser air charge, and reduce the engine’s exposure to damaging detonation.
A centrifugal supercharger works by combining the function of several components; including impeller, compressor housing, diffuser, and transmission. As in a turbo, the impeller is a turbine wheel that pushes air into the compressor housing at high velocity. It’s a small part that has a big job. It rotates at extremely high RPM and endures massive mechanical and thermal loads. It must be carefully engineered, precision crafted and balanced to hundredths of a gram. The compressor housing (volute) is the snail-shell shaped casting that functions as a collector, it gathers the air flow and delivers it to a downstream pipe. The diffuser’s job is to convert the kinetic energy of the air flow (velocity) into pressure (boost). This is accomplished by gradually slowing the speed of the air charge, allowing the air “behind” it to “catch up” thereby building pressure in the gas column. The transmission is the gear-set and bearings that support the impeller and multiply the input (crankshaft) RPM to the impeller. The impeller needs to turn at very high RPM to be effective. Typically, the impeller shaft is overdriven by a factor of 8. So if the engine is turning at 1,000 RPM the impeller is turning at 8,000 RPM, if the engine is turning at 6,200 RPM the impeller is turning at 49,600 RPM!
