Improving your car’s performance, so that it can drive faster, requires more efficient combustion. Just sending more fuel to the engine won’t achieve this – you need to modify the engine so that it accepts more air and fuel. Here are some ways to achieve this:
Install a supercharger
A supercharger pressurises air intake to above the normal atmospheric level. More air enters the engine and combines with more fuel, producing more power. A supercharger is powered mechanically via a belt or chain from the crankshaft, and spins at a rate of at least 50,000 RPM. This is faster than the engine itself. Installing a supercharger can be a DIY project.
Aftermarket air filters
These allow increased airflow into the engine, while blocking impurities and contaminants. A secondary air filter contains a thin layer of cotton housed between several layers of thin mesh that catch the impurities. Aftermarket air filters are easy to install. Simply drop it into the engine’s air box. Standard air filters are made from paper, but the aftermarket ones are made from fabric – so they are washable, and re-usable.
Air temperature can affect the performance of your vehicle. A cold air intake kit improves the efficiency of the engine, because colder air is denser than warm air. This means that colder air contains the required oxygen for a more dynamic combustion in the engine. Other benefits can be improved appearance of the engine bay, not to mention the appealing sound it produces.
The onboard computer
Late model vehicles have an onboard computer controlling many components, including the fuel-to-air ratio. Performance chips can be installed to override the factory settings. These are easy to install and allow you to set new parameters for the functions of your choice (such as to use petrol more efficiently).
A lighter car is more efficient, so to improve your car’s performance you can exchange heavier parts of the car for lighter ones. This applies to more than just the engine. For instance, you can remove heavy seats and install lighter wheels and tyres.
Performance exhaust systems
A catalyst-back exhaust system can free up trapped torque and unleash horsepower. All the important emissions parts remain, while the addition of a cat-back system lowers exhaust back pressure. It also results in a great sound from the exhaust system.
Note that the costs for each of the above performance enhancements can vary greatly. To get the best price on components, you should shop online. You will also save a lot of money by completing the work yourself. If you’re not so confident, get the professionals to do the job.
To make use of the increased power of your vehicle, you may want to look at lowering your car.
