How Do I Change the PSI on a Turbo?

by Richard Jennings

A car engine relies on the energy created during a combustion cycle to turn the various mechanics of the car in order to produce motion. A supercharger enhances the effect by increasing the air-fuel mixture, thereby increasing the ratio of vaporized gasoline to oxygen. This creates a more powerful reaction, and allows the engine to achieve a higher horse-power. Pounds per square inch, or PSI, can be used to measure how much air pressure the supercharger adds to the engine, this can be adjusted through the use of a boost controller, which controls the supercharger's rate of compression.

Open the hood of your car.

Connect one side of a length of hose to the wastegate.

Connect the other side of the hose to the boost controller.

Insert the plastic tee into the hose that connects the blow-off valve to the intake manifold.

Connect the tee to the other end of the boost controller using a length of hose.

Clamp the boost controller to the radiator fan shroud, and set the controller to the default setting, you can then tune the PSI to your preferences.
