HP(dyno) = 0.285 x CFM x 8(cyl) 0.240 for average bracket engine 0.250 for very good bracket engine 0.285 average factor for SS engine (low compression/high cubic inches a bit lower) 0.300 for high compression comp style engine 0.310 for very good comp engine funny, where is the cubic inches in that equation? ![]() Cylinder Head Choke Equation CSA(min) = bore x bore x stroke x RPM x .00353/614(fps) CSA = minimum cross sectional area of intake port Choke = point at which velocity impedes horsepower None of these are perfect, but we have been modeling them for the last few years and they make a lot of sense. Using cubic inches in Super Stock isnt a good idea. There is a reason Hemis make over 900HP and 455 Olds make 600. If you look at the Choke equation it will tell you why.
