Pulley rpm calculations
Since math isn't my strong point, I figured I would ask the experts.
I am trying to figure out how to calculate the difference in pulley rpms when you change the belt size on a thunderbird.
For example (all hypothetical)
7 inch main pulley
3 inch alternator
5 inch ac pulley
6 inch water pump pulley
84 inch belt
= what rpm for water pump and alternator
Now exchange that for a 65 inch belt and recalculate.
Any help or onllne calculators?
