Another follow up note on the M24 oil cooler. Spent this past weekend at VIR. Temps were in the 40s so it was cool. Max temps on the track were midway between the 210 mark at the bottom of the gauge and the next mark up the gauge (has no numbers).
As I noted after the Barber O'Fest event the temp recovery during cool down is remarkable. At VIR you get the session end signal at Oak tree and then track out approx 1 1/4 mile later. On this portion of the cool down the oil temp would drop to normal operating or just below before you left the track. I'm interested in seeing what happens this June and July when temps will be in the mid to high 90s. Otherwise cooler has been problem free as it should be.
