Aerofoils and spoilers
What is an aerofoil and spoiler and what does it do? Well, an airplane wing pushes the plane up by using the Coinda effect and the Bernoulli paradox. Air keeps travelling in the same direction after deflection, fast moving air creates low pressure. When the air over the wing is going faster than that underneath it generates life. In a car the principle is reversed causing down force.

Progressive boost controllers.
A boost controller will increase the amount of power you get from your turbo. The boost controller will alter the exhaust gases flow into the turbo allowing the turbo to spin at a faster rate. Standard boost control in most production cars can only be describes as crude. In order to keep costs down manufacturers stick with an archaic mechanical system of boost control.

Carbon fibre driveshafts
The driveshaft takes the power from the engine and takes this to the rear diff where it is transferred to the wheels. The driveshaft rotates at a fair rate and will to some extent act like a flywheel, resisting change in the rotational speed.

Aftermarket Superchargers
A supercharger compresses the intake air effectively forcing more air into the engine. More air means you have more oxygen and when this is matched to more fuel you will benefit from more power. There are a number of benefits to superchargers compared to turbos, but there are also some drawbacks. We aim to provide sufficient information here to allow you to ascertain if a supercharger will provide a solution to you.

Blow off valves or dump valves
In a turbo engine the pressures build up as air is compressed and forced into the engine. The turbo is driven by the exhaust gases so the faster the engine goes the more air you get forced into the engine. This is fine until you lift off the accelerator. You engine speed does not instantly change and you are not asking for fuel to go into the engine where does the compressed intake air go?
