Our ball and spring manual boost controllers are manufactured right here in the US. They can be used on any turbo application and can handle pressures in excess of 50 psi. Simply install the boost controller in-line between a boost source and the wastegate to fine tune the amount of boost you want to run. On average, an engine outputs an extra 10 hp for each additional 1 psi produced. This can reduce your 1/4 mile ET by a tenth of a second.

If your car has a turbo, let NXS Motorsports help bring out its full potential.
