Hi guys,

sorry for my bad english, as I'm from Germany.
I'm riding my 2018 EU GT MT on the Nürburgring Nordschleife, and sometimes it's overheating in only one lap.
I don't can see the oil temperature, but I can see it in the cylinder head temperature. Once it reachs 120°C (248°F) it will reduce the power and the rpm.


This could have been sub 8 min btg without the reduce power at the end because 120°C CHT.

I have my workshop installed an aftermarket oil cooler, it sits behind the water coolant at the higher front grill. effect: Zero. Really disapointing. So maybe the oilcooler doesn't really reduce the CHT? Or is it just not right mounted as it has no case with leads direct air into it? I have seen a aftermarket oil cooler behind the lower grill with a case which leads the air into the oil cooler, this seems to be better. Unfortunately my workshop decide not to do it this way.

Now I will order a 170° Reische thermostat.
Any tipps? I am hoping, I can let it as stock as possible. So I don't want to delete the stock grill. At least the higher grill with the pony badge. :-)
The car is almost daily driven, so I can't change the coolant etc.

regards
Philipp

Performance Pack radiator is where I'd start.

edit - never mind, you already got it.

You could drain out some coolant and just add distilled water back in. Just make sure to do a 50\50 flush before winter.

EU cars already have the PP hardware.

OP,
I would look into getting air out from under hood. There are several ways to do this. You can modify the cowl tray to allow pressure and air to escape. Fuel consumption on the highway will go up but your cooling will improve. You can install hood vents. A 170 deg thermostat will help a little. The other thing: I would strongly recommend taking the car in to ensure that there is not excess air in the cooling system, and that your CHT issue is not due to air pockets in the jackets/head.

No helmet for you or the girl (friend/wife?)...purse in the footwell...the dice...I would strongly recommend reassessing safety before going back out. Not that I have to comment on this (you know better than I) but that track is no joke and you're carrying some serious speed.

One small thing, from the video it looks like your air conditioning is on during that lap. I don't know if that might affect your max cooling capacity, but it might. At a certain throttle position, the AC is probably disabled automatically.

If you were really hardcore you could try to run the heater full blast during the lap, but you'd probably soak the seat in a pool of sweat...

Does he?
Turn off your ac?
Bigger radiator and your planned thermostat

Besides hood vents themselves mustang hood has air escapes on both sides/corners next to the windshield. Right where underhood rubber ends. Those are primarily for water draining.

Unless this is common I'd check if this car hss any cooling issues...

p.s. this is 18+ euro. do they get pp radiator?

If I wanted to track it regularly, I would start with a 100% Aluminum radiator...not the Ford PP radiator, since it has pressed on plastic parts. I would get something like the CASF, Mishimoto, or the Fluidyne.

Then, go with a high heat transfer additive, like Water Wetter in your coolant.

The third, some guys install Killer Chillers on their intakes to decrease air intake temps for boosted engines.

Have you tried a larger radiator? And you can try adding an electric fan to the oil cooler. But I would expect the larger radiator to have a bigger impact...
