In addition to the converter, the psi to pascal pressure conversion table can be a helpful resource. The converter calculates the equivalent pressure in pascal and displays the result instantly. It works by taking the input value in psi and applying the conversion factor of 6894.75729 pascals per psi. A restricted return line or introducing the return line into a high-pressure area (such as a Turbo main oil drain) can impact the OPR40’s ability to regulate the pressure.The pound force per square inch to pascal converter and conversion table provide a simple and efficient way to convert psi to pascal. Equally, it can only modulate if there return lines are plumbed without restriction. It does not need to be exact, but the OPr40 is quite precise. Ultimately, 40 psi was chosen as a target pressure as it sits firmly in the middle of the window of oil pressure requirements for the most common / performance ball-bearing turbochargers. We’ve pre-set it & not provided any adjustments to ensure you don’t have to risk your valuable turbocharger on startup by setting or adjusting the regulator – It’s good to go straight out of the box.Īs a guide, you will need at least 40 psi oil pressure. We’ve pre-set it to 40psi as this is the ideal pressure for most ball-bearing turbochargers. As mentioned above, this cannot be used as a T-piece, but a T-Piece on the outlet will provide enough oil flow for 2 Turbochargers. You will need to ‘Tee’ the Oil line after the outlet of the OPR40. There is also a 1/8NPT port for either a pressure gauge or a sensor.Ĭan I use just one OPR40 for a Twin Turbo? There are three fittings for the oil system – In, Out (to the Turbo) and bypass (to your engine oil supply/sump etc.). You should check with your turbocharger manufacturer about the supply requirements – We’ve found 40 psi suitable for most modern & high-performance turbochargers on the market.Ĭan I use it as a T-piece for my twin turbo engine? The 40 psi these are set at is suitable for Ball Bearings and other modern turbochargers of various bearing designs. It’s common to see this on startup on some engines where ‘cold’ engine oil pressure is relatively high. They work on an assumed oil pressure profile or usually around 40psi – If you have higher oil pressure than that in your Turbo, it can get straight past the ‘seal’ and cause smoking. Turbocharger seals are more like piston rings in an engine and are designed to keep oil out of the exhaust and, equally, exhaust out of the oil. It is a common misconception that turbos have seals that leak when they fail. Will this stop my Turbo from blowing smoke? This will provide you with rock-solid oil supply pressure within the manufactures tolerances.Ĭheck out the Turbsomart range of Billet Turbo Oil Feed Filters and our Billet Turbo Oil Drain Range. This takes the guesswork out of the restrictor or feed and drain hose selection and ensures the oil going to the turbocharger never exceeds the manufacturer’s tolerances. Turbosmart’s OPRt40 is a true regulator because a target oil pressure of 40psi can be achieved without compromising oil flow.

Traditional methods to limit oil pressure have been with a restrictor aimed at reducing pressure – However, this also reduces flow. Feeding these turbochargers the appropriate oil pressure has always been challenging. Many Turbochargers are built around a bearing and oil pressure profile much lower than is seen by modern & high-performance engines. Turbosmart’s Patent Pending OPRt40 is an Oil Pressure Regulator designed for your Turbocharger.
