Just about all car manufactures are using multi v belts these days.
I am sure Power Sport adapted something.

On the subject of V-belts vs. Multi-V-belts there are differing philosophies
floating around out there relative to their use on aircraft, and I was
hoping you guys might have some thoughts on the subject.

    Some say the flat multi-v-belts are more flexible, have less slippage,
are quieter, and put less strain on bearings and brackets than the older
thicker standard V type belts.  They also say they break easier...

Proponents of the standard V-belts say they are narrower so a pulley of any
given width can handle more belts and rarely require an idler wheel, and
they say more selectivity or redundancy can be applied where it's needed.
They also claim they're stronger, and perhaps most importantly, they claim
they are less likely to knock adjacent belts off their respective pulleys in
the event a belt breaks in flight and starts flailing around under the
owl.  ---  And the real truth is I  DON'T  KNOW  WHAT  THE  REAL  TRUTH  IS
!!!  I hope you guys can help :-)

Thanks,
