New from Summit Racing – the Sprintex twin-screw supercharger. These superchargers are a great way to add power to a small displacement engine. See more details below.

Official Release:

A supercharger is a great way to help a small displacement engine act like a bigger one—and a large displacement engine perform like a beast. Sprintex says bolting its twin-screw supercharger on a Jeep Wrangler with the 3.8L V6 increased horsepower by 27.5% (+37 HP) and torque by 28.5% (+55 lbs.-ft.) over stock. On a Wrangler with the 3.6L Pentastar V6, the results were even better—54% more horsepower (+127 HP) and 28% more torque (+68 lbs.-ft.).

Sprintex twin-screw superchargers are designed to make power right off idle without the lag a turbocharger can cause. The twin screw design is extremely efficient, requiring little engine power to drive and providing lower air temperatures at the intake manifold. That means more power with less stress on the engine.

The Sprintex superchargers are fully self-contained—they have an integral oiling system so you don’t have to punch a hole in the engine’s oil pan to run an oil feed line. They use the factory air intake system and take about six to eight hours to install. Most systems come with an intercooler and a Diablosport tuner where necessary. Kits for 2007 and later Mopar and Jeep vehicles with the 3.8L and 3.6L V6 are emissions-legal in all 50 states (CARB E.O. number D-695-1).
