Cylinder pressure will vary depending on the size camshaft used.Less overlap increases pressure. More reduces pressure. It's based on duration and LSA of the cam. For instance, my cylinder pressure varied about 10psi with a camshaft change of only 6 degrees of duration on the same LSA on a 10.8 CR. Cranking pressure went from 214 to 205. I'm guessing with a reasonable and suitable cam for your 11.1 engine, you should probably see any where from 200 to 230.
