I have roughly 1/2” of travel. Using a mark and a tape measure. Using a blow gun to feed it air the dial indicator spun too fast for me to count the times it went past 0

The arm on the turbo, you’re asking how far did it travel? It seemed to travel the same distance with the actuator on or off, moving it by hand

That’s probably not precise enough to give you the answers to what you were asking me
