As induction kits are probably one of the most popular modifications for car tuning projects we thought we should add a introductory article to explain what they are, what they do and the theory behind them.
An induction kit is quite simply an air filter. Most cars have air filters mounted in an air box. These filters are generally constructed of paper which filters out the particles from the air and prevents these from getting into the engine. The airboxes are designed to reduce the noise of the engine and have various vanes and angles cut to maximise this noise reduction.
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?
Ceramic exhaust coatings and exhaust wraps
Under 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.
Benefits and drawbacks of engine water injection systems
You’ve finished tuning up your engine but you find that at full throttle the engine splutters or stalls. When you get the car on a diagnostic you find that the knock sensor is kicking in to protect the engine.
Engine knock is a condition where the fuel inside the engine ignites prematurely and occurs within an engine running at high compression. (It can also be caused by other factors including low octane/poor quality fuel or hot spots within the engine.)
