Interesting... help me think through this. A smaller crank pulley means the belts at the crank turn more RPM's. A larger water pump pulley should slow down the W.P. RPM's? However, it would seem the P.S. pump would spin faster. Is this correct? Trying to think back to my old go kart days...
I purchased this set assuming they were stock diameter, and as well bought them strictly for looks! Now you bring up an interesting question!
With all that, why would underdriving a V belt motor be any different than underdriving a serpentine belt system?
