I measured the PTO pulley, and then the spindle pulleys. The PTO pulley needs to revolve 1.11 times to make the spindle pulley revolve once, so basically 10% more times per revolution. That, along with all the other math, makes the BTS in FPM much less than 18K, and nowhere near 19K, when the engine is turning 3450 on load. This is why I want to bump it up to where it should be turning the BTS as advertised at 18K FPM.
