It goes back to the same argument where if you try to modify something that 's not broken, it ends up broken.
Modifying the cooling system by putting a heater in front of the radiator isn't clever, it ends up broken.
You can argue that one for ever but the facts don't change.
If the water can absorb more heat then it will protect the engine for longer. In the same vein you could run a lower temp stat if you had standalone. It's then the job of the radiator to remove the heat from the water.
The only way the water can absorb more heat is by the temperature increasing.
The engine is designed to operate between certain temperature limits, simply put, too hot or too cold causes problems.
As I tried to explain to your redneck partner, I'm an expert in cooling systems because I live at 300 feet and to go anywhere I have to climb to 600 feet then drop to sea level over a total of about 4 km. Then the reverse to come home. I've been doing this at least once a day and I've lived here for the last 30 years. I've been driving for over 40 years.That tallies up at over 10,000 times. There's at least one car dies on the hill every day, sometimes it's just a lack of fuel, they die on the corners, often you see them stopped with steam pouring out. You can't live where I live and drive a car with a dodgy cooling system............all the locals toot and wave and keep on going.

Hillclimbs are always more fun than dragracing.
Of course you can't get away with doing this sort of thing anymore due to the cameras.
Just for the hell of it, here's a shot going up the other side, a bit slow though.https://www.youtube.com/watch?v=yX3SB-V1dqA
If you've got a RWD car with V8 and turbo you can get the rear wheels spinning right at 0.24 where you go over the tunnel.
Back in about 1990 there was no median barrier, one of my workmates got splattered on a bike when he T boned a van which had run out of petrol and the driver thought it would be a good idea to turn around by reversing and doing a U turn at the same time. That put me off bikes a bit.
But anyway.........hillclimbs are the best way to check out a cooling system. But not just a cooling system.
Dragracing, that's only a few seconds and things don't have time to get hot. The intercooler acts as a heatsink , as does the coolant. It then gets rid of the excess heat while it's sitting back in the pits, quicker if everything is black.
Likewise a dyno is pretty useless for testing heatsoak, very same reasons.
Circuit racing, each lap the temps climb higher and higher, often after about 6 laps or so, you'll see the limitations of your setup.
edit, I forgot to mention the towcar part of it.
4 tons all up with a full trailer on the back.
50 to 60 Ks all the way up, 2nd gear, 3000 to 4000 RPM, in and out of boost all the way......3 minutes to get to the top.
Never a single sign of trying to overheat with stock cooling system and SMICs.

Yes, yes, yes, that might be so, but you're clearly missing the bigger picture.....
