Speedmaster Flow Limits

Then there is the case where you get to a point where you hurt the low end lift pretty good and pick up on the high lifts pretty good. This, to me turns the head into a drag head where the valves are just simply shot open as fast as possible and then just hang out there for a spell before closing.

Not really a street head anymore at that point.

Having a nice fat curve is where it’s at and will make the most of the head in most every application.

IMO of course.
