There's been some pretty good dyno results out there after shoring up a carb, manifold, and head. What general method for calculation do some of you YT posters use?
What ever the choke points minimum cross sectional area cfm is usually makes 1 hp for 1 cfm conservately usually 180 cfm per cylinder will make 200 hp around 2000 rpm with piston speed being equal to or higher in fpm than engine rpm.
