The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.
Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.
Twin scroll turbosWe look at the advantages of twin scroll turbos, discuss how they work and how to set them up. People have used twin turbos in the past to address many of the problems you hit with a single turbo and the twin scroll turbo offers a neat drop in upgrade and provides many advantages.
Blow off valves, dump valves and screamer pipes
Blow off valves and dump valves.
When the throttle is closed (when you lift off the accelerator) in a turbo driven engine there is a build up of pressure as forced air is still coming from the turbo. Lifting off the throttle is a lot like putting a plug in the sink – the flow through is stopped and water would just build up and overflow the sink.
Boost controllers
The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.
If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power.
