So... all new cars run hot for the first 500 miles...
Rubbish.

Rubbish. Tech department probably has a weekly contest for who can come up with the most retarded excuse to get a customer off the phone. Kevin

Well BTU's are heat/power, it has to come from somewhere, we know the approx mass of the engine assembly, it's reported 30F hotter, we should be able to back of the napkin figure out the HP that should be gained by the reduction of new engine break in friction causing heat gain, and see if motor improves its HP output on the first 500? miles break in. If Hp does not go up proportionally, everything else being equal, myth busted IMO.
1 btu/h = 0.00039 hp

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

First off, the myth of slowing down coolant flow to keep the coolant in the radiator so it can “cool” is wrong. It has always been wrong and will continue to be wrong.
I read that guys post and I didn’t say much. It gets tiring saying the same [censored] over and over and over and it seems no one learns.
The longer the coolant stays in radiator, the longer it stays in the block. The longer it stays in the block, the hotter it gets.
Engine temperature control is about FLOW. Air FLOW and coolant FLOW.
Slowing the coolant down is ass backwards. You need a thermostat to set the LOWEST coolant temperature, not to set the maximum coolant temp.
If we can’t get that right, we can never control engine temperature.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

I wouldn't want it to run at 190. That's too hot for me and completely unnecessary. Modern engines are run hot for one reason, emissions.
Air flow, fan configuration, coolant flow, tune up including lean, water pump, 4 corner coolant flow on the intake, etc.
If the results don't match the theory, change the theory.

Besides slowing down the coolant flow, he should put some perforated metal sheet in front of the radiator to slow down the air flow, so it has more time to cool off the water...
