Thanks for the data Snowman. I have a question about the measurement technique though. A flow bench as I understand it is a large vacuum pulling air through a chamber. You can adjust the lift of the valve to see how it's travel impedes air flow. But to me that seems to be a static measurement. What I mean is that at low RPM these numbers are valid but as the RPMs increase I am not sure. Although most consider that air does not have a mass it really does on a microscopic level. To start it flowing in a direction (into intake or out of exhaust) there is a time lag (although maybe on the order of microseconds it could be valid). Therefore, higher lift may be important at higher RPMs to allow flow dynamics to occur. I will see if I can consult a friend who develops fluid dynamic software. That is really what we are talking about here fluid dynamics. At least in my mind. I guess it also depends upon where you want your engine to run best low-mid RPM or mid-high RPM. I would think the guys at Web-cam could help answer this question.
