After having my car on the road for over a year, driving Joisey roads, and attending an open track event, I can say that the
oil cooler is needed more for driving in traffic.
My
oil temp at the track did not really get over 180; enough to open the thermostat on the cooler. However, in Joisey traffic on these hot summer days of 90+, my
oil (and water) has gone over the 180 mark.
As far as pressure: I start up with 70-75 lbs and run, while driving and with the engine hot, around 50. I also have two remote oil filters and an Accusump pre oiler.
