Did my first HPDE in the Mustang this past weekend . I have 4 HPDE days prior in an e36 BMW ( 1993 325i ) .
Tires were 275/40/18 RE-11s (square) that had seen a few trackdays from @gtorpedo on Apex 10" wide wheels . They warmed up quick on a hot day and gave some decent feedback . Cold temps for me were set at 31 and were 38 after the session .
All my track days have been on Summit Point main circuit.
Temps during the day were 96 on Saturday , 90 on Sunday and we ran 30 minute session ( 3 per day )
Day 1
- First session went well , feeling out the track again , 435hp is much different then 180hp
- Second session was starting to push and get faster and smoother , about 25 minutes in got "rear axle temp warning". Air temps in 90s
- Third session , drove for 20 minutes , went to the pit and drove through to cool the diff a little , about 6-8 minutes later got the temp warning and came in.
I was riding with an instructor in novice class . I started the session 2nd in line with a C5 Vette in front of me , I passed him then saw no cars for a bit until I started lapping people . At the end of the session he told me "There is not much left for me to teach you"
Day 1 night , swapped diff fluid ( my exhaust was already wrapped around diff ) went from stock fluid to Redline 75w-140
Day 2
- First session , instructor tells me he is going to sign me off solo after this session. Ran 30 minutes , no diff warning message
- Second session , SOLO !! . Ran about 25 minutes then a Camaro beached itself in the gravel trap . no diff warning message... hey this Redline works ...
- Third session , doing well ,diff warning light hit at ~29 minutes , I slowed down and pitted in . I saw they were waving the checked , so didn't miss much time .
Thoughts :
- Have a tow hook , one car was stuck in the gravel for 25 minutes because they could not pull him out.
- My instructor was great , he drove a mildly prepped C6 Vette
- I might be able to get away with no diff cooler if the air temps were 10-20 degrees cooler and / or a slower track , and /or using a fan to cool the diff between sessions , and of course a group that ran 20 minutes instead of 30 . If I don't go and get a new car in the spring , I will get a diff cooler.
- I rode along with a friend of mine in his Lexus IS F ( Advanced group ) He's fast because he is smooth . I have rode with him before in a group that had 20 minute sessions . 20 minutes is too short , 30 minutes is almost too long , especially when you get to last session on Sunday .
- I can definitely see where I can make up time . I just need the seat time to put it all together.
- I only started to mess with recording my laps on the last session of the last day. I may of had a better lap then this
