Engine modifications

TorqueCars take a look at the power plant of a car, the engine and examine the wide range of engine tuning options availble.

Not all engine mods are effective and some need other modifications to work well. We outline each modification option and go into the benefits and weigh up the pros and cons of each.

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.

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.

Converting a DMF to solid flywheel

We look at the benefits and disadvantages of solid flywheel conversions from a DMF and help you decide which is right for you.

It is our considered opinion that unless a car is used extensively for competition or off road you should stick with a DMF. The additional torque caused by tuning an engine or heavy competition use can quickly destroy a DMF. The solution would be to fit a stronger, higher performance DMF but the aftermarket industry seems geared up to offer solid ones as the upgrade option.
