Was thinking about getting one of these. Its apparently 220amp's, but uses a smaller pulley to generate more current at lower RPM. Just wondering if anyone knows what belt size it would require.

Not sure if he will know

Generally speaking the belt usually rides on half or less of the circumference. compare old and new, get the difference and divide by half. subtract that from the belt and it should be close enough to work.
Otherwise, your current tensioner may be able to handle adjustemnt under 1/2 in,

Side note, most things spinning have an effective useable RPM range. A larger driving or smaller driven pulley may bring top RPM out of range at high engine RPM.

Side note, the required HP to spin anything will increase with a larger driving or smaller driven pulley.

luck

Excellent, thank you for the suggestions!
