Turbosmart ProOPR is a rising rate oil pressure regulator for your turbocharger(s). The ProOPR is boost referenced, not unlike your fuel pressure regulator and allows lower oil pressure at lower boost pressures and increases oil supply pressure to the bearing system at higher boost levels. This is designed for large turbocharger systems and high boost levels where the additional pressure and confidence is required at high boost, high shaft speed and horsepower levels.
The twin outlet system also creates a ‘T’ in your turbocharger oil supply line for simplicity of plumbing and connection for up to 2 turbochargers and while it is returnless, inline design it uses a boost reference to create a pressure differential. This pressure differential targets appropriate bearing pressure at low and zero boost pressure to eliminate your turbocharger digesting oil, while also providing increased oil pressure at higher boost levels to provide increased protection and confidence.
