The new one is a 30+ year old beseler 4x5. The old one is a 20+ year old Omega B66. I wasn't thinking enough to use the same negative. Honestly I was just trying to make a print more then doing any real testing. Let me put it this way. I screwed up the first test strip by leaving the lens wide open. With the lens at F/2.8 16 seconds was almost enough time. With the other enlarger a normal negative takes between 8-12 seconds at F/5.6. Hopefully I'll have some time this weekend to try again.
