Exhaustion often leads to extremely practical ideas from moms. It usually kicks in when the kids hit 11 or 12 and aren’t any good as Facebook Fodder any more.

Lol. I’m imagining striking it from nine different directions, then fifty hours of hand-fininshing.

Look on the label of the antifreeze label. It will show you the temperature performance for various mixes of water and antifreeze. Oddly enough pure antifreeze has a freezing point of just -10°C, but 50-50 mix with water protects down to -40°. Off the top of my head I think 60% antifreeze protects to the lowest…

Yep. That’s a good VW.

Danger to Headifold!

Well, it’s a turbo world now, especially in anything even mildly performance-oriented. If it’s a car that 10 years ago would have gotten tuned headers, it has a turbo now.

The days of backyard garage tuning of Civics are in the past.

It will dump more heat energy into the coolant, but as long as that energy is getting dumped out again by the radiator the temperatures won’t be any different.

Could you, though? There are too many openings from too many directions.

That makes sense from an energy perspective, but in practical application it doesn’t work. Heat breaks things, plus hotter gasses are less dense. If you can get the same volume/time flow at lower temperature, you get more mass/time. That pushes harder on the turbine, which means more choo-choo and more maaaad skids.

Nah, water will long remain the best coolant. It has the highest specific heat capacity of any common material and conducts heat exceptionally well. LongbowMkII is correct in saying that it’s only downside is freezing point. Antifreeze fixes that, though it does reduce heat capacity a tiny bit.

Temperature coming off the radiator probably won’t be higher, though. The cooling system’s target coolant temperature will still be the same. It will just flow more air to keep it there.

Kapit and Elson is one of the most beloved anatomy textbooks of undergrad kinesiology programs everywhere. I still have mine 15+ years later. It is a truly fantastic book.

Good point. Fatigue is a huge part of the job.

Yep. Equality is only achieved when women have the same access as men and it isn’t news.

Yep. The fact that John Force had so many daughters probably did more for motorsports equality than anything else.

In most other sports men have distinct advantages because of the greater strength and size that come from having nuts pumping out testosterone all day, every day.

A women-only series would reduce the pressure on the “old-boys” network and prevent change. The old-boys can just point at the pink cars and say “Well, princess, you can just go race over there. We don’t need to take you seriously.”

Gender segregation makes no sense whatsoever for most motorsports. Other sports are only gender-segregated because of the inherent advantages of power, strength, and size that come with testicles pumping out testosterone every day of your life as a man.

There are lots of ways to screw up the execution that would leave them vulnerable.
