ProCharger Introduces Revolutionary Programmable Ratio Supercharger

One of the inherent issues with superchargers is there isn’t an easy way to control boost; you have to pop the hood, remove the belt, and change the pulleys. People have put intake wastegates and boost controllers on superchargers, but this is typically bad for the supercharger, since it’s typically going to operate at full bore all the time. On the other side of the spectrum, large turbochargers create issues in form of turbo lag and increased under-hood heat – or smaller turbos typically taper off boost levels at higher RPM.

ProCharger has stepped up to the plate to create a product that’s undoubtedly one of the most revolutionary designs available in the aftermarket. What’s all the fuss? ProCharger calls it a programmable ratio supercharger. Think of a constant velocity transmission in a late-model vehicle that has the ability to vary gear ratios on the fly. When you take off from a start, A larger belt drive pulley with a smaller supercharger pulley will create immediate boost at low RPMs, and as the revs continue to climb, those pulley sizes begin to automatically reverse to give constant boost pressure at virtually any RPM.

The optional touch screen display will allow you to adjust boost levels on the fly.

The touchscreen display acts like a boost controller with four levels of boost. This technology will allow you to make more torque at a lower rpm, more horsepower at redline, and changeable on the fly for different driving conditions. There is no doubt that ProCharger’s Programmable Ratio Supercharger will be a strong contender for SEMA’s best product award.
