THE CLEVER PROBLEM

Turbosmart's new patent pending OPR40 is a true oil pressure regulator for turbochargers. It solves a problem that is usually misunderstood. However, to see the true magic in this solution, you must first understand the problem!

 

Turbochargers require a good source of oil and more specifically, they're built around a preference for a specific 'window' of oil pressure and flow. The turbocharger assembly itself has oil, hot exhaust gas and compressed air all within the tight confines of its core and this is where some compromises need to be addressed. The relationship between the three needs to be relative and that is because seals are in place to stop one mixing with the other.

 

A common misconception is that there is a seal that stops oil getting into the inlet air or the exhaust gas and that is simply not the case. The seal is, in fact, a gas ring and more resembles that of a common piston ring than any kind of rubber seal. Its function is to hold the exhaust gas or compressed air out of the oil system, not the other way around, as is often assumed - and it is here that modern turbochargers have created a little issue of their own.

 

With the reduction in the oil needs of turbochargers, there was a corresponding change in gas ring profile so that the balance of pressures fighting each other - exhaust gas, compressed air and oil - was maintained. This overall creates a beneficial system where less energy is consumed by seals and the bearing assembly, resulting in a more responsive turbocharger.

 

However, engine oil pressure requirements within a modern engine are often higher than that of the turbocharger assembly and this is where problems arises. Most of the engine requires a good steady feed of oil flow at high pressure for good efficiency and reliability, while the turbocharger's needs have reduced. The common solution, even at OEM level, has been to fit a restrictor in the oil feed line to the turbocharger assembly.

 

The problem with this method, though, is that there is a major difference between controlling flow and controlling pressure. The restrictor method that is most often used is actually an oil flow reduction method. What occurs is a compromise: reducing flow with a view to achieving a more suitable pressure, rather than directly reducing the pressure itself.

 

This method's impace on oil pressure is also subject to oil grade, viscosity and supply presure. A change in any of these variables has a huge impact on the resulting pressure and this is why this method can be tricky and cumbersome.

 

This is where Turbosmarts OPR40 shines. It is designed to regulate oil pressure without any impact on flow - simple as that. It's avle to achieve the desired oil pressure in the face of high supply pressure, at any temperature and resulting viscosity and does without impacting flow. It is a true regulator and takes the guesswork out of orifice sizing for oil supply and removes the need of the black art in the tuning of, and carefully balancing oil supply line size versus oil drain sizing for custom turbocharger fitment.

 

"It's one of those solutions we're truly proud to stand behind," says Chris Milne, Turbosmart UK's general manager. "Our guys came up with an innovative solution to a problem people have been frustrated by and barely coping with for years!"
