Hi Folks - kind of new here and wanted to ask a question. I'm having an engine cooling issue and wanted to know if this is common for Gen 3 S550 GTs. I have done some digging but it's not clear to me and hence my direct question.
I have mostly a track car ... '20 GT PP1 A10 but stock at the moment and I can't run more than 3-4 laps (maybe 6-9 mins) before I hit 250F CHT. I'm really surprise that this is occurring. I replaced the t-stat w/ a 170F because the OEM was defective. Around town, CHT is 182-198F range. So perfect/no issue. But when I open this up at the track, the engine gets hot very quickly. The trans temp is good for now ~ 221F max and the rear diff is okay for now as well ~252F max (note this is after wrapping the exhaust and changing to 75W-140 ... which made a huge difference).
Have others had this same problem at the track ... or is it likely unique to my car? Would appreciate your thoughts/experience. Thanks.
