Car racing has been a thing as old as cars themselves. Be it for professional car drivers or hobbyists, a project car will always be the most treasured piece an enthusiast could ever have. However, looking fast and being fast are two very different things. Don’t be fooled by aftermarket spoilers or corny racing decals because you’re not doing your car any favor.
Engines or race motors are probably the most important component of any racing vehicle. The race motors take in the mixture of air and fuel to combust, which becomes compression. The compression produced is converted into mechanical energy, which drives the transmissions to rotate the wheels with massive torque.
People tend to forget that mass-produced vehicles are mostly used for leisure or commute purposes where fuel economy is prioritized overpower. Keep in mind that more power also requires more fuel intake. You might even need to change your fuel’s octane rating depending on your setup.
Fuel delivery system
While the engine is the muscle that moves the car, the fuel delivery system is the heart that pumps blood for the body. Older vehicles have been using carburetors to supply the air-fuel mixture to the motor, but fuel injection systems are slowly replacing carburetors. Fuel injection allows more mileage and a more consistent air-fuel mixture delivery.
Modern-day fuel injection systems are controlled by a computer called an engine control unit. The system creates a mist of fuel, finer than that produced by any carburetor. The downside is that most aftermarket fuel injection systems are very expensive. Moreover, working with fuel injection systems requires knowledge in programming the engine control unit.
Ricers have been known for their annoyingly loud mufflers, but it is a known fact that better exhaust systems increase the performance of any vehicle. The most common characteristic of aftermarket exhaust systems is that they are significantly louder, but this is only a result of improved exhaust flow.
Engines that produce high compression also produce high exhaust flow. Stock exhaust systems are manufactured to suit the relatively lower compression from stock engines. Aftermarket exhaust systems are made wider to accommodate the high-pressure exhaust gases produced by an upgraded racing engine. However, this only applies to high rev speeds; Lower rev speeds need a narrower diameter, so it is always best to check with your mechanic first.
The most used component of a car is no exception when it comes to upgrades. Race tires give more traction than stock tires. However, the softer compound which gives race tires its exceptional traction also renders its life shorter. Nevertheless, you wouldn’t drive with race tires for everyday use.
Replacing the rims also brings about benefits for your car. Alloy wheels or mags have become the preferred material for rims rather than the traditional steel rims. Although steel is stronger, it is also significantly heavier. Alloy wheels have become the standard rim of choice for racing as it is noticeably lighter.
Fuel delivery systems, race motors, exhaust systems, and wheels are just four items you can change for your car. You can opt to change parts but keep in mind that not all car parts are created equal in quality, longevity, and safety.
