Thank youTough task for a street car to run full-tilt in those kind of temperatures. Some tips to help you;
1. Shifting below redline should be a lot easier on the car - and probably the best thing you can do to control temps
2. Don't run AC on the track
3. Water only (NO coolant mixed) would be best for cooling
4. When/if car becomes a more dedicated track car, remove the AC condensor.
Two of the more major changes to make the NFGT suitable as a street car was; 1) the addition of a comparatively heavy suspension and requisite hydraulic system, and; 2) the addition of air conditioning - including a condensor in front of the radiator. On top of these changes, I believe the street car also has more HP/TQ and therefore has even higher cooling requirements than the race car.
That is true, but I swap cars between my NGT and my Porsche GT2RS in same track session with no issues in the Porsche. It is not acceptable to me that the NGT has heating issues.In addition to ambient temperature, I'd also consider in the analysis Relative Humidity as higher RH can reduce the air capacity to transfer heat from the radiator. My recollection from a few years ago when I used to live in Dubai is that in October afternoon RH can get into the 60% to 70% range which when combined with high ambient temperature can make it very difficult for radiators to shed excessive heat generated by extended red line shifting.
Apples and oranges. High ambient temperatures combined with high RPM shift points on a road course is going to be the biggest challenge for the cooling system.I ran Big Bend Road Race last year, 120 miles at continuous speeds between 150-170mph, no problem. Also tracked at COTA without any overheating issues
COTA is a tough track on a lot of cars. I have a buddy who frequently runs that track and said the ZL1 1LEs frequently have overheating issues there.Apples and oranges.

Agreed. I should have been more specific insofar that I was trying to refer to the Big Bend Road Race. Tracks like COTA ARE definitely a challenge on cooling systems. OP is citing high ambient temps 90-100F. I guess what I am trying to say is that I don't think there's a unique problem/issue with the OP's NFGT. Any NFGT when doing hard track work in those kind of ambient temperatures is going to struggle (as is the 05-06 GT). The comparison shouldn't be, "i've tracked my car and it didn't overheat" but rather "I've tracked my NFGT in 90-100F ambient temps and had no issues with overheating/limp mode." Anyone done that?COTA is a tough track on a lot of cars. I have a buddy who frequently runs that track and said the ZL1 1LEs frequently have overheating issues there.
Surviving at COTA, especially during summer, is a big task.
