Noz Posted October 20, 2020 Share Posted October 20, 2020 Thinking to fit one of these after my turbo seal apparently popped due to excessive pressure. Anyone have any experience with this? Dont want to cook something by messing it up. https://www.waltonmotorsport.com/product/turbosmart-oil-pressure-regulator-opr-t40/?attribute_pa_colour=sleeper-all-black&gclid=CjwKCAjwlbr8BRA0EiwAnt4MTq-G7ssOELqOfBMq-IA1sUVqcUZ5S2yfLxVrrALNzJ1auxOQTDzO7RoCqV8QAvD_BwE Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 20, 2020 Share Posted October 20, 2020 Thats no small amount of money for what it does. Presumably you would need an external oil pressure gauge to attach to this to set it up? Quote Link to comment Share on other sites More sharing options...
rider Posted October 21, 2020 Share Posted October 21, 2020 From what I've read about Turbo design and evolution over the years the turbo oil pressure at max engine revs is typically around half of the oil pump delivery pressure. The usual way to throttle pressure of fluids would be in the delivery pipe design or throttle plate which will impose a flow restriction giving back pressure on the inlet relative to the exit flow pressure. Maybe you could just look at your oil feed pipe bore size as a means to throttle back the delivery flow reducing the oil pressure. That way it'd be a permanent setup whereas what you propose is very much variable and would require a gauge to monitor it. A pressure variable setup would presumably only come into its own as a benefit if you have a habit of switching massively between super thin to super thick on the oil viscosity grade of oil that you use; basically if the car is used regularly as both a track ragger and a daily driver. There has to be a simple equation somewhere online expressing volume in to volume out will change pressure by X. Here is an article on the flow and pressure options you have.

Sakey Posted October 21, 2020 Share Posted October 21, 2020 Never a bad thing but depending on what turbo you have, they run restrictors anyway specified in the manual. I would check first the oil drain size (make sure you haven't got a fitting smaller than the drain hole in the bearing housing or a clog) and give the PCV system a check over to see if right as not to pressurise the drain causing the pressure differential. If all this is ok, then I would be looking at a regulator. Quote Link to comment Share on other sites More sharing options...
Steve Posted October 21, 2020 Share Posted October 21, 2020 I would be asking the turbo manufacturer what size the oil feed should be and what size restrictor they recommend. Personally not seen something as flashy as what you have linked (I am a bit out of touch with current offerings though). Usually its just an inline fitting that looks something like one of these - https://www.ebay.co.uk/itm/Aluminium-Garrett-Turbo-1mm-Restrictor-Oil-Feed-Adapter-AN-4-4AN-To-M11x1-0-UK/124331779666?hash=item1cf2c06652:g:kusAAOSwWSJecbnN But check with the manufacturer on what size it should be.

Swampy442 Posted October 21, 2020 Share Posted October 21, 2020 Have you actually proved its excess oil pressure? Quote Link to comment Share on other sites More sharing options...
