A supercharger compresses the air that flows through it, thereby forcing more oxygen into the cylinders of any internal combustion engine to which it is connected. This influx of oxygen increases the engine's power and performance. Vehicle owners sometimes prefer to install superchargers for greater speed. Making a supercharger avoids the expense of buying one that is professionally manufactured. Take note, however: it requires extensive knowledge of your vehicle and its parts.

Instructions

  1. 1

    Remove the fan blades on a centrifugal air pump. You might have to use a power drill to core the rivet holding the blades onto the air pump.

  2. 2

    Open the bonnet of your car and pull off the air hose running to the intake on the engine. Use a tape measure to ascertain the width of the intake opening.

  3. 3

    Slide a metal sleeve the width of the intake onto the output of the air pump. The output is the end on which you pulled off the fan blades.

  4. 4

    Crimp the edges of the sleeve around the output as tightly as possible. Close a hose clamp around the sleeve and the air pump. Tighten the clamp until the sleeve is affixed to the air pump.

  5. 5

    Slide the metal sleeve over the intake opening of the engine. Secure it with another hose clamp.

  6. 6

    Connect the intake of the fan to the air tube you removed from the engine intake. Use the same method you followed when affixing the pump in place for the output.

  7. 7

    Connect the wiring of the pump to your car’s battery, fixing the positive wire to the positive terminal and the neutral to the neutral terminal. In general, red is positive and black is neutral, but check your specific items before making any connections.

  8. 8

    Secure the wiring connections with electrical tape.
