Hi All, can anybody clarify the temperature at which oil or water will cause a mechanical failure? I am trying to set a car up and no matter how hot i get the oil or water the engine doesnt overheat! The hottest i had oil and water was 115 was this close to the limit? Thanks in advance and yes engine wear and mechanical ARE on. The HUD never gave any overheating symbol/warning, am i to assume the engine was ok to run at this temperature?

That's a good question! Anyone from the community want to chime in?

I think after a while at a exreme temp (the water and oil) the motor just blows, theres no power loss or anything thats usually contributed to overheating that I've seen.

The cars are set up by default (the tuning screen) to where they wont overheat easily (the duct to the radiator is open enough to allow sufficient air flow to keep them from overheating). The more you close the ducts the hotter the engine will run, all the while producing less drag to slow you down.

Now if you dont move while bouncing off the rev limiter the water and oil will easily overheat.

I fully closed the radiators purposely to overheat it and then i intended to cool accordingly once i found the limit. The problem i have is... i dont know the optimum oil or water temps

I've noticed that the engine will let go at around 142 (oil temperature) it's really hard to get it up that high, unless you're hitting the rev limiter 24/7 or your radiator is damaged.

Is 140 the same for all engines?

Im not sure on that one. Primarily GT3 cars from what ive noticed.

GT3 cars should not go much higher than 110c

You want to keep the water temp at around 100c as that is boiling point and oil temp around 135c any higher for a long period of time will effect your performance and possibly blow the engine.
That's only if you have Performance Impacting set in the options.

Performance, no. Engine life, yes. Not sure optimal but keep it under 110c if you can.

Guys, better to discuss these thjngs in our "garage talk" sub-forum instead the xb1/ps4 areas. The physics is the same all platforms

LMP tends to blow between 120-130,reached 147 once,didn't end well

I blew it a few time but only after contact. I always try to tune so it stays around 100-110 degrees c. After a large bump or even a few smaller bumps I've seen the temps climb quickly and I limp it back for repairs.

At least for the LMP2s Casey said he will make the radiators a little tougher, they break a little too easily right now

wow 147?! how did you get to that? Highest I've seen mine is 134 and boom soon after

I have a similar problem with the Pagani Huayra. I set a 100% race duration (10 laps) and I always blow the engine.
How to decrease water and oil temperatures since this car doesn't have a radiator opening setting?

So do failures caused by oil/water overheating affect the cars in Time Trial? Or is that something else that can be unrealistically set in TT to get faster lap times?

Roger Prynne
03-06-2015, 11:56
Yeah you can get problems in TT as well, as you can still get the setups wrong and drive like an ass.

No I have problems in race mode (10 laps). Why time trial is more subject to these heating issues.

upshift at lower RPM and also downshift at lower RPM

lift and coast rather then thrashing the arse off the rev limiter,or change your gear ratios

on the z4 gt3 it will blow engine at 142 degree

every car will have different temperature extremes due to the differing engines. I dont pay as much attention to oil temps as I do water temps because the higher the water temp the higher to oil temp. I try to keep the water below 100c since that is the boiling point for water. i never ahd overheating issues with the GT3 cars, but often did with the P1 cars until i opened the radiator to 100% and shifted at lower RPMs during the race. Practice and Qual you can max each gear since you are typically only running 3-5 laps.

Hello again. Today I played with radiator and with default setting I got 100 C oil temp (water was almost same). I close radiator 50 to 30 % and temp 110 and I close more and got 115 C temperature.
My question is that what is maxium temperature? I read that optimal range is 230-260 C. http://www.motorstate.com/TheTemperaturesandPressuresofRacing.htm
I think that if its possible I close radiator to 5 %.

@Equation 240F= 115.5556C so it looks right.

Na mate... Wouldn't recommend it
The LMP1 cars cook their motors running >130C for too long

Dammit. I forget that those are F not C at my source :(

Yeah you want somewhere in the region of 100C to 120C to be on the safe side.

Lol.. 240C would probably be molten

In my experience most Petrol/Gas Racing Engines run best between 220-230F whatever that is in Celsius. Any knocks on the front of the car causes a temp increase. I don't know what a good brake temp is, I had mine shut down to 25% on my GT3 at Oulton. The rotors were glowing but the brakes in Telemetry were green.

Negative
That temperature barely affects metals in an engine. It's the fine clearances of bearings etc that seize from expansion. oil will get squeezed out, bearing surfaces will friction weld themselves together, heat will soak through the block weakening internals, snap crackle pop, doomsday etc...
No just kidding. If you're lucky you'll get a "mechanical fault" and Ben will call you into the pits if he's awake.
Or you get an "engine blown" and your car rolls to a stop and teleports to the pits with a DNF next to your name :p

does anyone have precise info on GT3 vehicles? (can't find anything at all...benchmarks at all?)
- Soft compound temps? optimal and max?
- Medium compound temps? optimal and max?
- Hard compound temps? optimal and max?
- Brake temps? optimal and max?
- Oil temps? optimal and max?
- Water temps? optimal and max?

Maybe water max temp is 100C... So optimal should be below, around 90C.

Tire temps are easier now with patch 3.0 - just keep it in the bright greens. Some tires like it around 80c mark, some 90, and the formula A keep it toasty at 100ish.
Brakes are dependant - carbon or steel. Steels start to fade above ~700c from what I noticed, and carbons don't work below ~400c and I don't notice them go bad til Engineer Ben chimes asks me to cool the brakes at ~1100c

The cooling system is under pressure. So it can go a little higher than 100C without damage. <110C should be fine.
