Inliners International Forums General Discussion Hi Performance Flowbench experts, what's a good figure?

Most of these will ask how many cylinders your engine has. As long as you have a port for every valve they work quite well. We don't get into trouble until the siamese ports come into play. To my knowledge no one has came up with a way to model them. For the most part, that only hurts when we try to get into the "tuned" intake and exhaust lengths and volumes for a particular RPM.
