Modern cars are faster and more efficient than those made decades ago, but there still are ways to increase the performance of a factory-made vehicle. Supercharging your Buick can be accomplished in a variety of ways, ranging from tune-ups to the installation of computer chips and additional components to increase the horsepower and torque of your car. You can choose one way or multiple ways to increase your car's speed and performance.
Tune up your Buick or take your car into a local mechanic's shop and have them do it for you. A thorough tune-up flushes out and replaces all of the fluids, cleans the spark plugs, the fuel injectors, the carburetor and the fuel filter, and is one of the most affordable ways to attain increased performance in your vehicle.
Install a performance chip into the engine control unit. These chips work by altering the timing of a vehicle's engine through computer enhancement, creating higher levels of horsepower and performance at the expense of fuel efficiency. Determine whether your vehicle is a newer model that will work with a chip or if it is an older car that doesn't have computer components.
Install a performance air filter to increase the top speed of your Buick. Clean filters ensure that only the cleanest air is getting to the combustion chamber of the engine, and the cleaner the oxygen, the better the combustion of the fuel, which increases engine output.
Install a turbocharger or a supercharger to increase the output of your Buick's engine. Turbochargers and superchargers work by forcing air into the combustion chamber of a vehicle, increasing the level of oxygen available for combustion, and while they cost several hundred dollars, depending on the manufacturer, it is a much cheaper option than installing a high-performance engine.
