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.
Tuning turbo engines. "A lot of hot air." What is a turbo. If you go back to your childhood you […]
Ceramic exhaust coatings and exhaust wrapsUnder bonnet temperatures are one of the biggest performance killers around.
Quite simply, you want your engine to be sucking in cold air as this carries more oxygen and will allow you to burn more fuel.
The exhaust system is one of the contributors to under bonnet temperatures. You can therefore lag the exhaust to help prevent this heat soak into the engine bay.
High performance valve springsThe valves are like the doorways into the engine and control the flow of the intake air and fuel and then after combustion they control the exit of the exhaust gases.
As you can guess the valve springs work incredibly hard, and as you increase the power of your engine the valve choice is vital.
TorqueCars will now take a look at the many considerations taken into account when selecting valve springs.
