I would be starting at 12 with an open end cap
If you don't have a sense of humor you probably have no sense at all.

An open end cap is equal to 8 to 10 discs according to SuperTrapp. I don't know how the relates to the difference between 3 1/2" or 4" discs but it is a start point to understanding the effect of the open end cap..

A simple leak by test on front then rear will provide a answer,  before a hot comp test

crummy comp tester.  that Chinese junk seems to work ok up to maybe 100 psi, then the gauge goes off.   I tried a couple different ones last year, then finally got an OTC (supposedly they make them for Matco as well?), and it was right on.  Chinese gauges said I was at ~175.  OTC said 210, which is right about what it should be.
