Why are superchargers not used anymore?
Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and increase power outputs, especially with reduced engine displacements. Next, the supercharger compresses the air which increases the air’s pressure and density. This way the engine receives more air through the same intake, which allows it to burn more fuel resulting in a boost in performance. However, that boost comes at an upfront cost. Notably, a loss of horsepower of as much as 20%.Adding a supercharger to an engine can greatly reduce its reliability. The added stress on the engine internals can put more wear on the engine in a shorter amount of time. However, if the engine is supercharged from the factory, it could last longer since it’s under the OEM manufacturer’s specifications.
Can a stock engine handle a supercharger?
When building an engine for supercharging (other than for racing), it is generally built for low to mid-range torque and power. This is similar to a stock engine. And because a stock engine can be used with a supercharger, it would be just as easy to operate or maintain. This makes it less exotic and more practical. This forces more air into the engine, providing a boost. With the additional air, more fuel can be added to the charge, and the power of the engine is increased. Supercharging adds an average of 46 percent more horsepower and 31 percent more torque.
