Tom, I think the second statement is more important than the first.
Specifically "1.5 inches of water column". If you drop that standard to
.5", you will have more power. The throttle will lose responsiveness
and control, but except for formation flying, I don't think there is any
need in an airplane for the type of throttle control a car generally
has. I'd gladly accept a few more ponies for the ability to perfectly
trim for 180kts vs 181kts. 8*)
