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

[Julian Kift]

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.
