Custom car ignition performance system is one of the most overlooked elements when it comes to engine and car tuning.

Most people think that once their car modifications are done, all they need to do is get the ignition timing right and turn the ignition. But it’s much more complicated than that.

For one, the spark must be strong enough to ignite the air/fuel mixture.

That might sound obvious, but what’s not so obvious is that air molecules act as an insulator, and when you modify your car to get more air into the engine, the spark from the stock ignition system might be too weak to effectively ignite the air/fuel mixture, particularly if you’re using a forced induction system. In fact poor spark quality can have as negative an effect on engine power as poor ignition timing.

The internal combustion engine is an amazing machine that has evolved for more than 100 years. It continues to evolve as automakers manage to squeeze out a little more efficiency, or a little less pollution, with each passing year. The stock ignition system consists of two circuits. There is the primary circuit, which is made up of the battery, the ignition switch, a ballast resistor, the coil itself (primary windings only – read on), the points inside the distributor, and low voltage ignition leads. The main purpose of this section of the circuit is to allow the low voltage charge from the battery to pass on through the coil, where the charge is bumped up a notch or two from the standard 12 volts to around 10,000 or 15,000 volts.

Within the coil there are two individual circuits as well. Regardless of the age of the engine and ignition design, one of the most efficient ways of modifying your ignition system is to install a high performance coil. Instead of a stock coil, which might have an amplification of 100:1 primary to secondary voltage (where the power from the battery is turned into ignition power).

Even more importantly, make sure your spark plugs are gapped properly. If the gap is too narrow the spark may not have enough time to ignite the mixture properly; and if the gap is too wide, there’s a chance the spark will be blown out especially in the case of the turbocharged engine where the incoming compressed air has serious velocity. It’s also important that you use the correct spark plugs.

If you use spark plugs that burn too hot, you could run into issues like pre-ignition, where the mixture is ignited by super-heated components within the combustion chamber, be they carbon deposits or a spark plug electrode. That’s not a good thing because the power stroke would come on a little too early and could cause serious damage to the piston, conrod or crankshaft.

As you can see, modifying your ignition system is not so much about achieving big power gains. It’s more about making the most of the extra power that has been developed through other areas of the engine, such as the fuelling and induction.
