cowl hood and carb tray type setup

[trkklr77]

in some of the more serious racing apps i have seena large sheet metal tray/scoop type deal to forcibly guide the air [typicaly from a hood scoop] to the air cleaner. it basicaly creates a air ram and incoming air has nowhere to go but in the carb.

?????????

1 has anny tried that on a cowl hood, say a 4-6" hood.

2 do you think it would help or hurt the air flow in a cowl hood setup where the air is being sucked off the windshield and not forced down a scoop.




i have the tools and materials to do it, i just wanted an oppinion on the idea.
