Hi Joe,
My take is the end to end method, coupled shafts or on
the same shaft, would essentially be zero coupling
loss. And the side by side method would have some
coupling loss, in the chain or gears or whatever. But
that loss should be very small and be associated with
just half the total power.
Overall, if you use a good chain or gears, I really do
not think you'd be able to tell the difference in
efficency between the two methods. My guess is
something maybe like 1 percent. Choice is usually
dictated by space constraints in the vehicle.
The Killacycle uses the side-by-side with a chain.
White Zombie uses the end-to-end, on the same shaft.
Take a look at those web sites.
Hope that helps,
Jeff M
