What is twincharging and how does it work?
Twincharging. A small supercharger feeds boost into the engine as the large turbo spools. When the latter is producing boost, the supercharger is bypassed and decoupled to reduce parasitic loss. That means big, efficient power; near-instant response; and a long, flat torque curve from a relatively small engine.
How do I set up a twin charged engine?
A twin charged engine is best set up on a rolling road with proper diagnostic equipment and most cars will need an aftermarket ECU to cope with the extra mapping requirements. It needs to go between the Turbo and supercharger if used in compound charging or the back pressure when the throttle is closed at high revs can destroy the supercharger!
