You don't know what a hot engine is. Sprint car headers glow in the
dark, hotter than red not.

So did the new tubular exhaust headers of my TR4A and Lotus Cortina way
back in the 1960s when we strapped the cars on the dyno to see how much
the horsepower was boosted by new Webers, intake manifolds, headers,
exhausts, cams, et cetera. The shop had big floor fans to help dissipate
the heat. The TR4 was a great little sports car, by the way. The Lotus
Cortina had reliability problems. Both were bought new.

Working below decks on a hot boat engine is mechanical hell. At least
the auto engines are transmitting their heat to either the outdoors or a
large indoor space such as a service bay.

Good point. My fast answer is a twenty inch box fan from Wal-Mart,
with a small cheap inverter. You blow it on the mill as long as you
can put it off, and then it blows on you. Technically, you don't have
to cool the mill totally, just the outer skin that is radiating the
IR. Hard to figure how that would work out. The water cooled exhaust
must help a lot compared to a car. The family bought a Turbocraft in
the fifties. Hull number 10, of the first jetboats ever sold in the
us. It had a flathead six with a doghouse with two latches. Ten
seconds work and the motor is 90% exposed. Two minutes to change the
plugs. Two hours for the Navigator. Why does a truck need four cams?

The guys who worked on my TR4 and Cortina had really large fans mounted
to blow over the engine and to exhaust the hot air outside. We all did
some SCCA racing in those days. The guys in the shop were serious; I
just did it for fun.
