I can build a splitter to run at just about any speed you want. The question is how much do you want to spend. I have found the 3 seconds out and 2 seconds to return is about as fast as you want to go and still be reasonably safe. 26 gpm with a 4" bore cyl running at a TRUE 3000psi is a nasty splitter and will give you that cycle time. If the round is off set on the shoe it will leave with enough force to become airborn. CJ
