I had my first track weekend after installing my oil temp and oil pressure gauges (I don't have a DIY but I will make a thread with part numbers and a few pictures shortly). I wasn't able to get a camera to record the gauges but I did have an instructor ride along for 2 sessions and watch the gauges.
On a side note I had my best weekend ever - in the first session I beat my previous best lap of 1:31.6xx by a few tenths of second, and in my 2nd session I had a string of laps in the mid 1:30.xxx with 1 lap in the high 1:29 and one 1:29.6something that was a full 2 seconds off my previous best
So the car was working hard
Car:
2000 Boxster S, 119,000 miles, EBS Baffle, UD Pulley, 2nd Cat Delete pipes, Low Temp thermostat, DT40 oil, Hankook R-S3 tires, stock USA M030 suspension.
Outside temp was between 60 & 70 F.
Water temp never got past the 0 in the 180 and in fact barely ever got past the middle of the 8. Oil temp got up to 220-225 during my best runs when I was pushing it the hardest but mostly stayed around 200. Oil pressure at idle was around 20 PSI when the oil was hot, the rest of the time it was up past 40-50'ish. I only checked on the straights.
I did have an instructor ride with me and look at the oil pressure as I was going through turn 1 & 2 which is a really long right hand sweeper with a declining radius at the end. He saw the oil pressure dip down toward 20 PSI in the turn but it came right back up. That was concerning to me - I have never seen an explanation for the drop that didn't include the oil pickup sucking a little air which can't be good....
I have a 3 QT Accusump that I haven't installed yet, so I think I am going to install it before my next track weekend which is Road Atlanta in November.
