Our funny car doesn't have a radiator, water pump, or any coolant lines.  However, the
block is filled with coolant and two release valves are mounted on the water pump
mounting locations.  obviously, idling for a length of time requires shutdown when the
temp his close to 250 degrees (I think).

In fact, after a 1/4 run down the track, the engine is shut down for overheating
reasons, as well as to prevent damage to the cyl walls.  See, the pistons have small
holes drilled in them that allow some combustion pressure through to push on the top
ring even more.  During deceleration of the engine, this apparently causes more wear.

I just drove and was following orders <grin>
