Single-Belt crank pulley conversions go even further to
provide you with the highest possible power gains. They are also a
requirement in many of the Acura-Honda engine swaps where the stock
pulley will not fit because of clearance issues. The single belt
design only drives the alternator (includes any accessories also
driven on the same belt). This makes for an extremely light piece that
will provide you with excellent power gains. Single belt crank pulleys
are also perfectly streetable and can be use din applications where
the A/C and P/S are being removed for street or track use.
