REFLECTOR: Getting Air to the Engine

[Keith Hallsten]

Aach!  What unfortunate positioning of the fuel servo for a pusher
installation!  I think that some sort of external scoop/expansion chamber is
going to be the way to go for that.

I'm also thinking about some sort of air scoop for induction and air filter
housing.  So far it sounds to me as if Rene' Dugas has the best
installation, so I'm thinking of trying to emulate that.

Subject: REFLECTOR: Getting Air to the Engine

I am trying to find a way to get air from the runner to the rear facing 
(forward relative to the engine) air intake on the engine. I cannot get 
a 3" scat hose from the runner to the intake since there is not enough 
room below the engine or above the plenum in the cowlings. I would like 
a solution that does not mean putting another bubble in the cowling.

I was wondering if anyone built a flat slot under the engine with 3" 
fittings in each end in order to attach the scat to the runner and 
engine intake.

If that is not a good option, then I guess I will put a P-51 style scoop 
under the engine intake on the cowl with a filter and have air enter 
there for the engine.
