[DeTomaso] NEW PRODUCT - 351C Fast Water Pump Pulley

That is actually part of the cooling system design.  Removing the thermostat
can actually make an engine run hotter due to the speed of coolant flow
though the radiator.  Coolant is not in the rad long enough to lose enough
of the heat.  Moroso has made special restrictor plates (large washers) to
use in place of the thermostat.  I ran a 351C in a 78 Mustang back in the
day, and had to run the 5/8 hole plate to keep temps under 200 degrees.
Without the plate and thermostat, engine temps would continue to rise until
overheating when running in the city.

Considering a 4.9 inch vs. 5.5 inch pulley diameter I'd say likely yes. I
cannot recall or picture off the top of my head how much contact
circumference the belt makes with the water pump, but if it's half the
pulley then the belt length difference is almost an inch.
 
Interesting statement which I had not considered previously, but if the
Pantera crank pulley is 5.5 inches vs. 7 inch on other Ford models and all
the accessory pulleys remain a constant size (is that true?) then all the
accessories are being underdriven by 27%, so that includes the A/C
compressor, alternator etc. Is there truly a restriction to using a larger
crank pulley to address that root cause?
 
If the alternator is being underdriven is it stil supplying optimal 14.4
volts at idle? If not then those big ass fans are probably also not running
at their design speed at idle and that maybe contributing as much as reduced
water flow to overheating.
 
Bear in mind most aftermarket high volume water pumps put out around 30%
more flow than a stock pump already and cost about the same as this pulley.
At some point the restriction to increased flow likely becomes the
thermostat.

and Mustang, had much larger crank pulleys. As large as 7 inches! This new
351 Cleveland water pump pulley will spin your water pump 11% faster than
the stock 5.5 inch pulley!
