Message	Total lag time = time to get into positive manifold pressure + time for turbos to hit target boost. Most dynos I see have the car already in boost, this doesn't account for the amount of time it takes to go from vacuum to whatever that boost was. Real world example: two identical z32s, one with say 530 turbos, the other with big ones (who cares), at 3,000 rpm they both stand on the throttle, whatever you envision happening is real world lag. So, smaller turbos (stock, 500s, 2554s) will provide more low end torque for drag and especially road courses. Mark
