Mythbuster: continuing project thread of my 1303 '75

[judgie]

it wasn't as much the amount of lift i said the turbo responeds to but the amount of time its open. the valve needs to be open and flowing for as long as pratical but big lift numbers are not allways needed as long as the flow is there.
hence why i said a faster ramp to get to the max lift would poss work better than just more lift, but you need the valve train to support the faster ramp.
the amount of boost will also play a big part in this. at a guess you could almost stall the airflow in the port with high boost, this would cuase a lot of turbulance around the back of the valve and poss even fuel seperation.
i have no real data to back any of that up just info from what i have seen and been told.

Thats just the point Rob: more lift usually means more flow, especially in my case: I have 46mm intake valve and just 0.50" lift, which just isn't optimizing what the port can flow, at all.
A turbo engine really responds to that the same as n/a, maybe even more so.
YMMV of course
