I was curious. I have a fully built bottom end with 9.5-1 compression. What should I get for psi number? I just did a compression test and it is 150psi across the board. The motor has a thousand miles on it now and it seems kinda low to me. I had regular oil in it for about 500 miles then switched to synthetic. I think that I might have to put regular oil back in it so that the rings will seat. Let me know what you guys think.
