As I suggested before, if you can increase the travel of the power tube you can expose more of the ports. That could be a problem though because your hammer would need to sit further forward using the standard location of the face of the valve nut.
I had the idea of counterboring the valve nut inlet on the first or second page.... Would that work to increase the amount of valve surface area exposed?
