Quote: the original design of the cowl hood scoop was to direct cool air by picking it up from deflecting it off the windshield
And it does function fairly well. There is a high pressure area at the base of the windshield.
And to those that posted they went slower, have you given any consideration that the difference in air (be it less or more with the cowl hood) affected your a/f ratio at certain speeds?
Just a though.....
Cowl hoods DO FLOW AIR into the engine.
I dont like the looks either.
but if you study the various configurations and placement you will see that many are too far from the glass to catch the air and let the scoop do it's job.
Since the advent of the taller heads/intakes from Indy, Preditor & B-1 as well as class rules its clear as to why so many are using cowls but some followup questions for the cowl hood.....
1) Should you seal the cowl scoop to the carbs?
2) How close to the front windshield should the end of the cowl scoop be for maximum air? I see some real close to the windshield almost touching it and others 6 inches or more away from the windshield.
