I have a new idea. Since 99% of the footards I run into do not know the difference between RWHP and Flywheel HP I thought about figuring my FWHP numbers for my 17# pulley (seeing 18psi), using the guestimated 15% rule to come up with just under 725 FWHP. Since it is just a plate and for kicks and shiggles would it be wrong to put "725HPSVT"
