Applications: High PSI turbo diesel and drag racing. Flanges to suit 2" outside diameter tubing. The ProGate-50 Lite HP is the largest wastegate in Turbosmart's high-pressure range, with a 50mm valve size. The ProGate-50 Lite HP features a specially engineered high pressure cap, designed to effectively control extreme boost pressures. With a base pressure of 35 PSI (2.4 bar), the ProGate-50 Lite HP is ideal for heavily boosted turbo diesel and drag racing applications. And at only 28mm taller than the standard ProGate-50 Lite, the HP remains ideal for tight engine bays.
