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.
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.
Blow off valves, dump valves and screamer pipes
Blow off valves and dump valves.
When the throttle is closed (when you lift off the accelerator) in a turbo driven engine there is a build up of pressure as forced air is still coming from the turbo. Lifting off the throttle is a lot like putting a plug in the sink – the flow through is stopped and water would just build up and overflow the sink.
You can increase the power of an engine by increasing its capacity. This is a fairly involved process and requires a good deal of research and preparation. Unless you want to have to retrace your steps and go a different route midway in to the job.
Some of TorqueCars.com members have had their engines rebored ,and this does seem a good way to increase power. However there are a few things we should take into account.
