Does a Supercharger Replace the Intake Manifold?

In the broadest terms, the installation requires the following: Replacing the stock intake manifold with the supercharger compressor/manifold assembly. Swapping the throttle body onto the supercharger system.

Do supercharged engines have intake manifolds?

Both normally aspirated and supercharged engines rely on something called manifold pressure (pressure inside the intake manifold) to get air and fuel into the engine's cylinders.

Can you just bolt on a supercharger?

A bolt-on supercharger can add anywhere from 30 to 50% more power to an otherwise stock engine. The hot setup is a small displacement blower (say 144 cu. in.) running at an overdrive of 1.75 to 2.25 that delivers 6 to 9 psi of boost pressure on a small block V8.
