- If we want our small engine to perform like a big engine, or simply make our bigger engine produce more power, our ultimate objective is to draw more air into the cylinder.
- compressors used to compress air into the cylinders of an engine. The additional mass of oxygen containing air that is forced into the cylinders improves the volumetric efficiency of the engine which allows the engine to create more horsepower.
Know the difference!
- But what if someone is trying to decide between a supercharger and a turbocharger? This question is hotly debated by auto engineers and car enthusiasts, but in general, superchargers offer a few advantages over turbochargers.
- The key difference between a turbocharger and a supercharger is its power supply.
Something has to supply the power to run the air compressor. In a supercharger, there is a belt that connects directly to the engine. It gets its power the same way that the water pump or alternator does. A turbocharger, on the other hand, gets its power from the exhaust stream. The exhaust runs through a turbine , which in turn spins the compressor
- Performance gains come from a consistent 20-30 degree drop in peak temperature resulting in less knock and more HP and reliability due to the cooler charge.
A turbo is a high technology product that requires superior design and intensive capital to produce. It must meet the severe requirement that only a world class manufacturer like Garrett can achieve.
