Supercharger vs Turbo. … A supercharger doesn’t work off the exhaust gas, it is attached to your engine and spins with the crankshaft. When the crankshaft spins the supercharger, it forces air into the motor. The turbo is more efficient as it doesn’t require engine power to spin it, so it makes more power per boost.
How much horsepower does a turbocharger give you?
Supercharger or turbocharger
Also known as forced induction parts, both of these components force air into your car’s engine which improves horsepower and torque. A turbocharger works with the exhaust system and can potentially give you gains of 70-150 horsepower.
