Is the number of ports in engine really tied to performance?
Hi guys,
I have a question, is there a direct relationship between the number of ports of an engine and its performance?
e.g. Is a 3 port .12 engine really slower than a 5 port engine?
My experience is that I have a Max S5 which is a 5 port engine, on a Mugen MTX3. Then later I got a Sirio Collari modified 3 port engine. Both these engines have been running on the same car and same exhaust. However, I feel that the Sirio is a bit faster than the Max. Well really I do not have a laser gun to check what's really the speed of the car, its purely based on my feeling and the observation of my peers.
