Fuel & Ignition Upgrades at Dales Motorsport

The ignition/fuel system is one of the most overlooked car accessories 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. In addition, an air/fuel ratio of 11 parts air to 1 part fuel, which is a fuel rich mixture, is most conducive to spark ignition. However, the air/fuel ratio for the proper burning of the fuel is 14,7 parts air to 1 part fuel. Thus, the air/fuel mixture is not ideal for a spark ignition system, particularly during cold start conditions where fuel vaporization is not as effective.
