For a few auto enthusiasts, the car that rolls from the assembly line isn’t quite up to speed, so to speak. Some drivers like to tinker using their cars’ engines, adding more power or improving fuel-efficiency. But what might you do when you need to feel a little more rumbling coming from that engine?
Ordinarily, an engine handles air intake using this method: A piston moves down, creating a vacuum, allowing air at atmospheric pressure being drawn in the combustion chamber. Combined with fuel, it forms a unit of energy, which is transformed into kinetic energy (or horsepower) via combustion, thanks to an ignition from the spark plug.
To improve a car’s performance — in other words, making it go faster, something all car aficionados and gearheads crave — would require more powerful, or at a minimum more efficient, combustion. More fuel alone starting the engine wouldn’t work, because of the delicate relationship between your oxygen inside the air along with the fuel essential for the combustion. Instead, modifying your car’s engine to accept more air and fuel is the key. Listed here are five ways to modify your vehicle to make that happen.
