Turbochargers vs. Superchargers
Have you ever wanted to know how to make your car go faster? While I can make no guarantees that your car will be a qualifier for the next Fast and Furious movie, I can coach you on how to get the biggest bang for your buck, or in this case, speed from your engine. The simplest method for boosting speed is installing a force induction system that consists of either a turbocharger or a supercharger. Most turbochargers and superchargers can be bolted on to your motor with minimal to moderate modifications. While both types of systems can produce significant amounts of horsepower, turbochargers are the better choice based on extent of horsepower gained, pricing, and its efficiency. Turbochargers increase horsepower more than superchargers because they receive energy directly from the exhaust system. Superchargers are connected to the engines crank belt and spin simultaneously. Because they are connected to the belt, superchargers can only spin as fast as the belt spins. In general they produce a much wider power band than turbochargers because they make larger boosts at very low and very high rpms, creating boost over 20 psi (pounds per square inch). On the other hand, turbocharges are connected to the exhaust manifold and utilize high-energy exhaust gases to spin the turbo. Because these systems are not physically connected to the engine, they can spin much faster and more freely. This means that turbochargers will generally create more boost than superchargers, in many cases producing over 30 psi. The more boosts you can create the more horsepower you can have. When it comes to pricing, both of these force induction systems costs around the same depending the brand you buy. Superchargers and turbocharger usually go for about $4,000- $6,000. You can achieve huge savings with these types of systems by buying and creating your own parts. Superchargers consist of the...
