Side effect of overheating

From another old timer. In the 60,s in Australia a lot of the cars being
raced had water injection
where water was bled into inlet manifold. You could even buy kits to fit to
your daily driver. Suction
from inlet manifold just socked a tiny amount of water from a tank in engine
bay. Cars apparently (allegedly)
ran smoother, cooler, better mpg.
