Supercharger Kits for Cars & Trucks

Supercharger Kits for Cars & Trucks

Supercharger kits are complete forced induction systems that add a belt-driven air compressor to naturally aspirated engines, delivering immediate boost pressure across the RPM range without turbo lag. Complete kits include the supercharger unit, drive pulley, belt, intercooler (if applicable), intake manifold, and all required mounting hardware and tuning components.

Popular Supercharger Kit Types

The two most common supercharger types in aftermarket kits are positive displacement blowers, including Roots and twin-screw designs that deliver strong low-RPM boost and excellent throttle response, and centrifugal superchargers that build boost progressively with RPM for a power curve similar to a turbocharger. Both types are available as complete bolt-on kits for many popular GM, Ford, Chevrolet, and Dodge V8 and V6 platforms.

How much horsepower does a supercharger kit add?

Supercharger kits typically add 50 to 200 horsepower or more to naturally aspirated engines depending on the kit design, boost pressure, engine displacement, and supporting modifications. Most bolt-on supercharger kits are designed to work with stock fuel injectors and engine management systems, though larger power gains often require supporting upgrades to fueling, intercooling, and engine management calibration.

What supporting mods are needed with a supercharger kit?

Supporting modifications commonly recommended with supercharger kit installations include a high-flow cold air intake, upgraded fuel injectors matched to the new power level, a heat exchanger or intercooler upgrade for positive displacement blowers, and a professional ECU tune to optimize fuel, ignition timing, and boost pressure for the new configuration. A proper tune is critical for maximizing power and protecting engine components.
