AdamB Posted March 31, 2013 Share Posted March 31, 2013 Personally I would run an aftermarket gauge and try it first, some engines are different to others so will respond differently to more or less oil pressure. Failing that run a proper standalone ecu and have an oil pressure warning system set so it cuts the engine when oil pressure drops below 1 bar Quote Link to post Share on other sites
5e colin Posted March 31, 2013 Share Posted March 31, 2013 i run a 2.5 mm washer on my forged 5e but it does 8.5k Quote Link to post Share on other sites
Asad Posted March 31, 2013 Share Posted March 31, 2013 As Adam says, build it up and check to see where the pressure is at...tolerances are different with each engine so can lead to different pressures then you can take the necessary steps Be interesting to see what zisco says Quote Link to post Share on other sites
AdamB Posted April 1, 2013 Share Posted April 1, 2013 (edited) You only have to drop the sump and put a washer in there, no harm in dropping the sump once or twice during run in period anyway to remove any swarf shit from the bottom. Colin makes a good point though, if you are expecting to run a high rev limit its adviseable to increase the oil pressure to ensure the bottom end does effectively run dry at such high revolutions.
