I'm having an issue with both Porsche 911 GT3 R's running very hot, between 218 and 230f. I also have high engine damage, between 14 and 18, between pit stops. I don't know if both of these issues are related. I have 0% damage to the car and it happens at every track, whether I'm in a race with other cars or in private testing. Please help!

what's the outside temperature? and how far open is your radiator?

If, for example, you're in a summer Dubai it's not weird to overheat with standaard radiator settings when hammering a car on a track, isn't it?

Radiator is open to 100%, air temp is anywhere between 75f and 90f

Raced a full series with these cars and never had an issue - unless i had front damage - in which case the cars temps did skyrocket. Are you racing with damage on ? and if so, any small bumps on the front causing damage will effect air intake temps. If not, the only thing i can think is you are going to rev limiter for every gear shift and or downshifting too quickly. (if on manual gears)

Racing with damage on, no damage to either car (0%) this only happens to the Porsche 911 GT3 R's. I've practiced using other GT3 cars, they run around 200f with warmer air temps but no where close to the temps that the Porsche runs

I've also done more than 50 hours in the GT3R. Never any overheating problem, just when there is front damage. It is always slightly higher in temperature than the other GT3's. Most are under 100 Celsius on stock setup, the GT3R is mostly round 105 Celsius. But that doesn't cause engine damage, that will start to happen with 120 Celsius or more (nearly 250F). Did a 6 hour race in it, no damage repairs done during stops, engine was 98% or 99% in the end.

So I guess the temps you see are normal, and the damage might be overrevving? Maybe on the downshifts?

Ok, thanks for the info
