The intake depicted would make for a pretty bazarre cowl.  I doubt you could bury

applications, I would need some really really convincing evidence that inertia
wouldn't sling the atomized fuel to the runner wall on the outside of the turn(s)
from whence it would just sort of dribble into the chamber.
Just a theory ....       Jim S.


The first 12 to 18 inches is straight so I imagine that is where most
of the evaporation will take place. Mecanair has the 180 degree turn in their
pipes so apparently that is not a problem. It is sure to dribble into the
chamber if you have the injectors near the port. 

It is fairly easy to have injection bosses in both places and check 
your fuel burn each way.
