A little known trick when racing your M15 is this:

get the crew to wrap their lips around the drain (takes some practice) and have them blow gently. This introduces air bubbles to the flow thus reducing drag. conservative estimates range from 1 to 2 percent increase in speed.

I'm getting visions of top-secret air pumps hidden below, one way valves, variable electronic control..... Steve Tyree
