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.

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.

Benefits & advantages of Winter tyres & snow tyres

With the poor winter driving conditions hitting the UK in 2010 many drivers are looking at winter tyres. Other countries are prepared for the snow and poor weather and are used to the concept of winter tyres.

So what are winter tyres, what do they do and are they a good idea?

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.
