ProOPR Rising Rate Turbo Oil Pressure Regulator

Turbosmart ProOPR Rising Rate Turbo Oil Pressure Regulator

The Turbosmart ProOPR (Rising Rate Oil Pressure Regulator) is engineered to deliver precise, boost-referenced oil control for high-performance turbocharger systems.

Unlike conventional fixed regulators, the ProOPR dynamically adjusts oil pressure in relation to boost—providing lower oil pressure at low boost and increasing supply pressure as boost rises. This ensures optimal lubrication across the entire operating range, reducing the risk of oil leakage at idle while delivering maximum protection under high load, high shaft speed, and extreme horsepower conditions.

Designed specifically for large-frame turbochargers and high-boost applications, the ProOPR offers a simple, inline, return-less solution with a single outlet configuration—making installation clean and efficient for single turbo setups.

By using boost reference to create a controlled pressure differential, the ProOPR maintains ideal bearing pressure at low or zero boost to prevent oil ingestion, while increasing oil pressure at higher boost levels for enhanced durability and confidence when it matters most.
