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.
Suspension settings, lowering and stiffening
On the track your priority is fast cornering and suspension plays a large part in this. Track conditions are quite forgiving and you can make some compromises like using hard suspension and lowering the car for optimum aerodynamics and a low centre of gravity.
This works well because tracks are fairly flat and you do not have a carrier bag full of eggs in the car from your return trip to the supermarket.
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.
High performance valve springs
The 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.
