GN7, thats a good idea. I might go that route. I think that is the best way to add something without tearing apart the motor. Maximus brings up a good point though that a v-drive only uses one keyway for the prop and propshaft. They also see alot of overdrive, so they spin even faster.

even when we don't run a blower we still run the blower type setup including the ATI blower damper and a six bolt adaptor for the universal joint take off.
