Many car enthusiasts customize their engines by adding a turbocharger to improve engine performance. In cars equipped with a turbocharger, a boost control allows the user to increase boost pressure and gain horsepower. Although modern cars can control boost power electronically, various cars do not have this tuning option. In such a case, installing a manual boost controller, also known as MBC, allows the user to increase boost by hand. You can make your own boost control using items from hardware stores.
Instructions
1
Insert the spring inside the male barbed fitting. Flare the ends of the spring slightly so that it cannot slip out of the fitting, and will "cup" the ball bearing.
2
Insert the ball bearing inside the female barbed fitting.
3
Screw together the barbed fittings so the spring presses the ball firmly against the inside of the fitting to seal off the hole when the two barbed fittings are assembled. If the spring is too short, simply stretch it out. Trim the spring if it is too long.
4
Blow through the female barbed fitting. If you can easily blow through, keep turning the fittings to screw them together until you cannot blow through the fittings anymore.
5
Attach the boost control to the manifold or VAC source line and wastegate line with hose clamps. Position the boost control so the fitting with the ball bearing inside is towards the manifold or VAC source.
6
Use the boost control by tightening or loosening the fittings. Test drive the car when you adjust the fittings to determine whether you have reached the amount of boost desired.
