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.

Vents – adding performance with Bonnet vents.

Performance gains are possible with the addition of bonnet vents.

Warm air really does kill performance. This is due to the air intake temperatures being hot and air at high temperatures carries less oxygen.

When driving an engine hard the under bonnet temperatures quickly build up and the engine has no choice but to suck this air in reducing your power.

Comparison of Turbo’s and superchargers

Both work on the same principle they blow air into the engine under pressure. Both have a turbine which spins up depending on the engine speed and the higher the revs the greater the volume of air is forced into the engine. But there are some major differences between the two and which is best for your project?
