Overheating Engines in BeamNG

I’m partially trying to decipher if this is a flaw in my design, or if something is off about my exports to BeamNG. I have noticed that my V8 engine designs are prone to overheating, especially after revving for a short period of time without moving fast, such as performing burnouts, or digging my way up a hill in off-roading scenarios. I’ll provide an example of the aftermath of a V6 vehicle design climbing up a mountain compared to a V8 design to show exactly what is happening.

As you can see, this SUV fights to the top of the hill while still running at normal temps. Some minor temperature increases, but nothing detrimental to my engine, as it stays at a reasonable threshold the entire climb.

Now compare to this V8 design. This truck was nearly boiling by the time it made the climb up the hill, although both vehicles accomplished the task in a similar span of time. The bigger the engine, the more pronounced the issue seems to be. I have also tried to use smaller 4 cylinder engines, even with turbos, and still no overheating like with the larger V8s. Is there something I’m missing about managing heat with larger engines? I know these test aren’t scientific, but it seems like my V8’s are uniquely vulnerable in these such scenarios.

Cooling in exported cars is something we’ve been working on a fair bit over the last little while. Suffice it to say, we’d like to have a look at the car that’s having overheating issues so we can analyse what’s going on.

Yes, of course! Here are two very different builds that experience the same issue, but at completely different levels. The one entitled “Spartan Hoplite” is a reasonable build with a N/A pushrod 5.7 V8 and 4x4. This truck gets pretty warm under a bit of struggle, as depicted in my original post. The one entitled “Motorex Street” is a supercharged 6.4 pushrod V8, and here the problem is much more pronounced: this build has an absolute nuclear melt-down almost immediately when revving. In fact, if I line up for a drag race and rev the engine for a big launch, the car practically explodes before the tree even turns green, which only takes a few seconds. No bueno.

Okay, here they are. If I’m doing something stupid with my design, please lmk
