KraftWerks builds supercharger systems around the Rotrex traction-drive centrifugal supercharger, designed in Norco, California. Shop KraftWerks supercharger kits for Honda cars and K-series engines, plus kits and upgrades for UTVs like the Yamaha YXZ and Honda Talon. You'll also find KraftWerks supercharger pulleys, belts, and idlers for tuning boost, along with intercoolers, intercooler piping, and blow off valves. Most kits are built for a specific vehicle and engine, while some pulleys and accessories are universal, so confirm your application before ordering. Nearly all KraftWerks products in this collection are for off-road and competition use, and many UTV parts are built for off-road use by design.
KraftWerks Performance Group designs supercharger systems for import cars and powersports vehicles, for street and race use. Every KraftWerks kit is built around the Rotrex supercharger and designed in-house at the company's facility in Norco, California. The lineup spans Honda cars and K-series swaps, popular sport compacts, and side-by-side UTVs.
Supercharger kits. Complete bolt-on systems that typically include the Rotrex supercharger, mounting brackets, belt drive, intercooler or charge piping, oil system, and fuel or tuning components for the application. Coverage includes Honda Civic and K-series engines, and UTVs such as the Yamaha YXZ.
Superchargers. Rotrex supercharger head units and service assemblies for building or refreshing a system. [VERIFY: models carried]
Supercharger pulleys and belts. Pulleys in different diameters for changing boost, plus belts, idlers, and tensioners. A smaller supercharger pulley spins the Rotrex faster and raises boost.
Intercoolers and piping. Intercoolers, intercooler piping kits for the Yamaha YXZ and Honda Talon, and a universal intercooler fan kit for UTVs.
Blow off valves. Standard, large, and trumpet-style blow off valves for KraftWerks systems.
Turbo kits. A small number of turbo kits.
A Rotrex supercharger is belt driven, so boost comes on predictably with rpm and there's no turbo lag. Power delivery feels like a larger engine.
A turbo uses exhaust energy and can make more peak power for the boost, but has a spool delay.
Many owners choose a Rotrex for its linear, factory-like feel on street cars and the compact packaging that suits UTVs.
Not enough power from a naturally aspirated engine, which a supercharger kit addresses with smooth, rpm-linked boost.
Heat soak on UTVs at low speed, which an intercooler fan kit helps reduce.
Belt slip at higher boost, addressed with the correct belt, tensioner, and pulley combination.
