Just my take on this snorkel inquiry. I previously ran a
snorkel...currently run the same size opening in a hood scoop on my Comp
Coupe. I believe David Visards 1 sq. inch to 25 HP would work fine in Drag
Racing. My experience at 200 MPH plus at Bonneville has that equation more

down a small hole at over 200 MPH. Placement of that opening is also
critical to this discussion.
Love that Daimler idea. Again this is what makes Bonneville so cool.
Lets see the F/BFCC record is 230 MPH...now if I....
