Here is a 944SSie I built with big valves and intake ports filled in with a bit of epoxy, to pump the midrange. (blue line) The red line is a ported 944SSie built somewhere else that was claimed to make 107hp by the builder. The great thing about a dyno is, it can be a a good B.S. meter. Back to the subject at hand, it appears the 944 kits like a smaller port, if ultimate peak hp is not the goal. A great street engine!
