The velocity pressure (pressure required to accelerate air to a specific velocity) of 7000 fpm is 1.3 psi. The static pressure or friction losses along any reasonably aerodynamic pathway that is only about 2.5 ft. long are going to be small compared with this. So the strategy would be to avoid any unreasonable pressure drops.

Slade what about installing an electrical air ram device, it would compensate all the loss you are talking about... isn't it?
