title pretty much says it.

on a stock Eaton...

the higher the RPM's of the eaton are the more power it takes to spin it.

With an 8# pulley, 10# pulley the eaton is way over spun, but how much hp does the eaton take to spin that fast at high engine RPM's.

 

To damn much.

 

i think i remember reading somewhere that at max rpms, the eaton takes something like 60 HP to turn it. the KB advertises that it takes 14 less HP than the eaton (60-14=46hp)

 

i dont know about the eaton but a 14-71 roots takes 300ish

 

I remember seeing the 60hp figure too. Don't remember if that was overspinning it or not?
