I've not needed to duct airflow before, but finishing my Wild Hare 35%, I think I should. Location of head and holes in cowl front look very direct, so I think I have to manage "exit area". I'm not running canisters, so was thinking of opening both exit holes at the rear of the canister "tunnel", and putting a 45* one inch deflector in front of that opening. The rear of the tunnel is angled, so between it and the deflector, I'm thinking I'll have pretty good "ducting".

Question - should I still open up more area under the fuse?? Thoughts?
