Crank keys for blower applications
Whats everyone runnin for crank keys spinnin blowers. Factory woodruff, full length 3/16. Full length 1/4, dual? Whats the experienced opinion?
Personally I have a single full length key, if it survives the season i plan to possibly double key. What boost level do duals become necessary. I see where many have sheered a factory woodruff key. Not sure I've seen anyone take out a full length key with a proper fit steel hub though.

Full length 1/4 key will handle most things as long as the press fit On the balancer is tight!
