I was curious, since my supercharged set up will be running between 9psi or so. To do that with my Eaton, it’s going to require about a 2.5” pulley. I was thinking that rather than go with the small blower pulley to spin the blower harder (that will most definitely result some in belt slippage), wouldn’t it be more practical for me to go with a larger crank pulley, that would spin the system faster and allow me to use a larger diameter pulley for the blower? Doing this would still allow for the proper ratio in order to make the required boost, while increasing the available surface area in which to contact the belt face and would lessen slippage?
Not only that, but it would also spin the water pump faster at low RPM, to improve cooling in the city. True the Alternator would spin faster at high RPM as well, but it’s easy to just swap out to a large pulley to bring things down to safe speeds again.
I figure doing it this would have to be cheaper than converting to an 8-rib set up to achieve the same results?
Any opinions?
