Slightly strange head flow question.
I want to bring this thread up again! its a interesting question!
-Where is that edge where the engine not answering to more cfm?
usually for me(read backyard tuner) I used to stick to known combos, or hack together something and test:cheers:, but now,
I have this program called PIPEMAX, it cost a few bucks but is worth every cent. just type in some basic numbers about the engine and this program calculate cfm needs to make the power the camshaft is capable of!
If you look at the pic, you see the one row (3. from left) that is piston CFM. This is the cfm value the piston is capable to "suck" ... so I guess there is no need to go beyond this number. (sure you have to use correct area and length on intake runner! this is the hard part:D make alot of cfm out of a small and not optimised port)
