I just bought a splitter that has a 5x24 inch ram, a single stage pump, and an early 75 hp Pinto engine (1600cc). I cut a few pieces of hard stringy elm that any of my Mauls couldn't touch and at Maximum pressure just before splitting I got 1500 psi at 2200 rpm on the worst stuff. Most cuts were at 500 psi and 1200rpm high idle. The stuff was so hard and nasty I think I'd have broken or bent the ram on a smaller splitter. I had to drive 340 miles to get it (Craigslist), but only paid $1500 and it's professional quality. I'll try to post a picture and video this weekend.
