About Turbochargers, Superchargers & Parts
Turbochargers and superchargers force extra air into the engine so it can burn more fuel and make more power. Buyers come here to replace a worn or damaged turbo, add boost parts or upgrade a turbo machine.
A turbocharger is driven by exhaust gas, while a supercharger is driven by the engine itself. The listings here are mostly turbo parts for Polaris and Can-Am machines: complete and replacement turbos, upgrade and conversion kits, wastegate actuator kits, and boost and charge tubes, which carry the compressed air between the turbo and the engine. A boost module appears in the examples for Maverick X3 models. Parts are model specific, so pick your machine in the Ride Finder at the top of the page. An upgrade changes how much fuel the engine needs, so read the listing for what is required, such as a tune or other parts, and check how modifying the engine affects your warranty.
Brands here include S&S Cycle, Dynojet, XDR and Bikeman Performance. More air needs matching fuel and clean intake air, so also look at Fuel Injectors, Air Filters and Air Hoses, Lines & Pipes. The whole group is Air Intake & Fuel Delivery.
FAQs on turbochargers and superchargers
What is the difference between a turbocharger and a supercharger?
Both compress the air going into the engine. A turbocharger is spun by exhaust gas, while a supercharger is driven by the engine, usually through a belt. The result is more air for combustion, and either one needs the fuel system to match.
Do I need a tune after installing a turbo upgrade?
Usually yes. A turbo upgrade changes airflow and boost, so the fuel and engine settings must be adjusted. Read the listing and the maker's instructions for what else is required, and do not run higher boost than the instructions say.
What does a wastegate do?
A wastegate controls boost by letting some exhaust gas bypass the turbine once the target pressure is reached. The actuator is the part that opens it. A stuck or leaking wastegate actuator can cause low boost or too much boost.
What do boost tubes and charge tubes do?
Boost and charge tubes carry the compressed air from the turbo to the engine's intake. Cracks, split couplers and loose clamps leak air and lower boost, so inspect them whenever you service a turbo machine.
