Ron -
This all looks very good; however, it doesn't take into account the
(claimed by some) loss of flow efficiency resulting from high rpm
'cavitation' in the water pump. Another factor found in engines with
cooling systems that have not been well cared for is corroded water pump
vanes resulting in seriously degraded flow. The "replacement" oversize
Mini-Cooper pulley is supposed to reduce the former. The solution to the
latter problem is obvious.
Some "racers" suggest by-passing the heater with a tube to increase the
coolant flow around the rear of the head without frying their feet.
In any event, if you chose to run without a thermostat, the available
blanking sleeve reduces the effects of dumping cold coolant onto the front
of #1 cylinder. Closing off the by-pass between the water pump and the
head is also recommended in this case.
