Big valve kits – larger intake valves.

The heads primary job is the mixing of fuel and air and delivering this to the combustion chamber.

Any turbulence or drag can restrict the air flow into the engine starving you of power. So this TorqueCars article will focus on the intake valves and how they can be improved.

The aim of head tuning is both to maximise the amount of air and fuel that gets into the engine, and to improve the mixture. Read More...

Boost controllers and remaps

Boost controllers
The turbo is driven by the exhaust gases and the faster the exhaust flows the quicker the turbo spins and more air gets forced in to the engine.

If too much air is forced into the engine then it will run lean. This causes an intermittent loss of power and you also risk putting too much pressure on the engine with a surge of power. Read More...

Turbo tuning and power gains on turbo engines

Tuning turbo engines.

"A lot of hot air."

What is a turbo. If you go back to your childhood you probably remember those windmills sold at the seaside. Imagine a windmill with 2 propellers back to back.

As the wind blows the first propeller a shaft turns the second one and it will blow air in your direction.

A turbo contains 2 impellers which are located in the exhaust flow and along the intake path. The exhaust side rotates as the exhaust gases flow and this turns the impeller on the intake effectively sucking in fresh air.… Read More...

Chip Tuning – better engine management.

The days of fiddling around in the engine bay with a spanner to make the car go faster are numbered.

Modern engine computers (ECU’s) take over many of the controls of all aspects of engine management from timing to fuelling and more.

This actually means you get better power, a cleaner burn and more reliable engine but it does not mean the end of tuning. Read More...
