I was hoping some of you more experienced track guys could help me out. I was at the track this past weekend, I got a total of 6, 20 minute sessions (1 hour between each session). For the first 4 sessions I took it pretty easy, driving about 6/10's of my ability, and for the final 2 runs I drove closer to 9/10's of my ability. Towards the end of my 5th and 6th sessions, I noticed my temp gauge went up to about 3/4 of the way, at this point I immediately let off and drove her back to the pits to cool off. My temp gauge has never moved above the 1/2 way point, and always stays there once there, so this had me a little concerned. It is also important to note that prior to my 5th session, my car had been running (idling) for about an hour with the AC on, and I did not shut off the AC until the second that I left the pits to get onto the track.
92 NSX, no engine mods. 70k miles, coolant hoses replaced 5 years ago, no coolant loss from overflow, no visible coolant in oil.
Outside temp was about 85-90 degrees
I have put about 200 miles on my car since, without any issue or overheating.
I will be changing the coolant this week, and doing a closer inspection for any coolant loss. Is there anything else I should be looking at?
Thanks guys!
