Many Turbochargers are built around a bearing and oil pressure profile much lower than is seen by modern & hi-performance, engines and feeding these turbochargers the appropriate amount of oil pressure hase always been a challenge. Traditional methods to limit oil pressure have been with a restrictor, aimed at reducing pressure – However this also reduces flow.

Turbosmart’s OPR T40 is a true regulator in that target oil pressure oil 40psi can be achieved without compromising oil flow. This takes the guess work out of restrictor, or feed and drain hose selection and ensure the oil going to the turbocharger, never exceeds the manufacturers tolerances – This will provide you rock solid oil supply pressure, within the manufactures tolerances.
