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.
Roll cages & Roll bars custom fitting kits
Many tracks insist that cars are fitted with roll cages and or roll bars. In motor sport competitions you will see that most regulations also insist on a roll-cage. What is the job of a roll cage and are there any advantages to having one fitted? More and more Torquecars members cars are being fitted with roll cages, so is this just a new styling trend or is there something beneficial to the car tuner?
Roll cages offer protection to the driver and tighter body control.
How to add a turbo to a non turbo car.
The basic reason for forced induction (turbo or supercharger) is not to increase compression or the maximum pressure in an engine cylinder, it is to increase volumetric efficiency (the efficiency of the engine at drawing in air) although forced induction is the most effective method of upping compression.
In computer games we just tick a box, and within seconds our car is fully turbocharged and running much faster. In the real world things are very different.
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.)
