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.
Superchargers offer the promise of substantial power gains with very few drawbacks. So lets look at the growing popularity of supercharger kits and see what its all about.
A supercharger is quite simply an air compressor which helps push more air into an engine. These are driven by a belt from the engine effectively creating pull on the engine sapping up to 30% of the engines power.
Clutch tuning: performance clutch modifications and triple plate clutches setup
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.
Cryogenic engine treatments
When putting more power through an engine you need to ensure that every part will perform at its optimum.
One of the motorsports favourite techniques to improve the durability of an engine is a process know as cryogenic treatments.
As you can guess from the use of the word Cryo – it involves the cooling and heating of the engine block to temper the metal changing its structure.
