I estimate approx. 96 square inches of inlet opening on my S1S cowl. I est. approx. 196 square inches of outflow opening at the bottomthe cowl (1 to 2 relationship). I've heard that the rule of thumb to provide the best flow is 1 to 3. I can enlarge the opening at the bottom of the cowl a bit, or bend alip to help increase the low pressure vacuum.
Any advice?
Thanks
Dave
