ply33 Posted May 22, 2016 Share Posted May 22, 2016 My notes at http://www.ply33.com/Models/PB/specs.html indicate it should be 74 PSI at cranking speed. Link to comment Share on other sites More sharing options...
hchris Posted May 22, 2016 Share Posted May 22, 2016 Although its not an exact exercise, if you just multiply atmospheric pressure (nominally 14.7psi @ sea level) by the known compression ratio, in your case 4.9, then you will have a ball park figure to work by.
