I developed a toothed belt drive that reduced the pump speed.
My research showed it to be more efficient than a "V" belt.
Bearing shops have the info; center to center, max speed, etc.
aluminum toothed stock is sold per length; was quite expensive.
I have seen Formula Fords with very small pulleys and belts; I went much
larger.
The block pressure was OK on the dyno, and it survived pace and victory laps,
and many very hot ambient races.
I slotted the pump mount holes and the housing to block holes, so that I did
not need an idler pulley (No charging system) with a std. length belt
Perhaps the FOT archives have my posts?
