Options For Tuning An Aspirated Petrol Engine

Engine tuning is a common practice among car enthusiasts who want to improve the performance of their vehicles. The amount of tuning you give your car will depend on how much you are willing to spend for an expert in vehicle performance and tuning.

Tuning Naturally Aspirated Petrol Engines

Boosting the engine combustion to increase the output power requires more oxygen.

A car engine produces power by converting the energy potential of fuel. However, the engine output shaft gets only about a third of the fuel energy after the process because a third is consumed by the cooling system while the rest escapes via the exhaust pipe. Boosting the engine combustion to increase the output power requires more oxygen.

Adjusting the components of your engine is not advisable because every part of the system is built to work in sync. Modifying any part of the engine can severely alter its performance parameters, not to mention, void its warranty.

Tuning Solutions

Professionals in vehicle performance and tuning work on improving the airflow in the system through several techniques:

Fitting a high-performance air filter allows more air to enter, leading to power gains of about 2%.

Increasing the capacity of an aspirated petrol engine means more fuel and consequently, improved power. More capacity can be achieved by installing oversized pistons or enlarging the cylinder bores.

Nitrous oxide is a popular choice of engine tuning for street racers. The NOS is compact oxygen whose particles are released in the combustion chamber, allowing more fuel to burn.

Performance camshafts can give a vehicle approximately 5% more power by decreasing the resistance they put up, which lets air gets into the system.

Power gains can come in the form of a free-flow exhaust, which requires the removal of the catalyst and silencer that hinder air flow.

Using a fuel octane booster will increase the ignition timing, which leads to higher compression ratio and more power without risking engine knocking.
