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.
Remapping the ECU – remaps benefits and issues
Back in the good old days – the task of timing the ignition spark was performed by the distributor. The greater the RPM, the more the timing would advance.
This did a reasonable job but for the most effective power you would need to vary the timing to a greater degree than a fixed ratio advance curve. The electronic ignition system was borne.
Building a 10 second car
We look at what it takes to build a 10 second car and examine the power and weight requirements to reach the sub 11 second goal on the drag strip.
Follow our tips and you can make a 10 second car quite cheaply and within your budget with some power mods and serious weight reduction.
How to tune a car engine for power or economy
Let’s take a look at ways to tune a car engine and what exactly we mean by engine tuning.
First up we have to accept that there are many different types of engines.
We can only cover generic theory in this article on how to tune a car and suggest if you want more specific advice you sign up to our car forums where our helpful and friendly members will assist you further.
