The Methods Of Forced Induction

Decent Essays

Superchargers and turbochargers both are methods of forced induction. Forced induction is delivering compressed air to the engine. The reason for forced induction is simple more air means to more power. When the engine is using the compressed air, it is called boost. Superchargers and turbochargers are the two common types of forced induction. A supercharger is driven by a belt like an alternator. A turbocharger is driven by the flow of exhaust. The debate of which is better is one of the most talked about debate and there is no right or wrong answer. There are pros and cons that make it imposable to say one is better. There may be one that is better for your use. Turbochargers are bolted on the exhaust headers using exhaust gasses to spin and spool an impellor in the turbo. This is efficiently using energy that would have been wasted. When the one impellor is being spun by the exhaust the other is sucks air in the engine making boost. Since the turbo is powered by the exhaust a lot of heat is made. You do not want that to go through your engine because this could cause the engine to overheat. To prevent overheating problems an intercooler is installed. The air travels through the intercooler during the proses the air is cooled. One limitation of turbo is turbo lag, because the turbo is driven by the exhaust it takes some time for the impellor to spool, but once it is spooled you can get full boost quickly. The advancements in turbochargers have made turbo a lot better
