- Boost Valve for Dmax LB7
The KD Boost Valve is a simple device that installs in the wastegate hose simply and easily. It eliminates boost pressure from the wastegate actuator until a preset level is reached, at which point it begins to deliver a lesser psi. By doing this, the turbo uses more of the exhaust to drive the compressor rather than allowing peak drive psi to escape. The result is much quicker turbo spool up and a potential increase in peak boost pressure. The device comes preset to a safe level near stock depending on programming and engine breathing capabilities. Simply cut the wastegate hose and insert the valve with the bleed hole on the wastegate end. To increase boost you will shorten the overall length and to decrease you will lengthen it. To come back to start point, adjust so that the overall unit is approximately 3″ long.
Simpler than installing an aftermarket wastegate canister, and much easier to adjust. With proper adjustment, it can be used in conjunction with aftermarket wastegates as well.
