YES, YES but not necessarily for a high revvving engine - since the mod was
used on production road engines (A-Series).

I take as my basis for this theory that the cam gear is larger than the
crank gear. This is so that the cam turns once for every 2 crank turns.
Intake valve opens once for every two "up" sweeps of the piston. Right??
So if you increase the diameter of the water pump pulley won't it turn
slower than stock?? I assume that in those hi-revving engines this is to
reduce cavitation.
I am not a thermodynamicist, nor do I play one on television.
Just thinking with my mind open.
