Jman1991 Posted February 18, 2017 Share Posted February 18, 2017 I recently tested my cylinders in my Loyale with a SPFI EA82 the PSI I recorded was Cylinder 1 - 150 PSI Cylinder 2 - 140 PSI Cylinder 3 - 140 PSI Cylinder 4 - 135 PSI I,m looking for the proper PSI for this engine so I can compare it with recordings that I took. If anyone knows the specifications I would greatly appreciate it. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 18, 2017 Share Posted February 18, 2017 That's a 9.5:1 engine. Ideal numbers at sea level would be 190 psi. But the number isn't important as much as the difference between highest and lowest. Ideally you want less than 5% difference between high and low. It's most likely low due to valve sealing. Probably needs a valve lap/grind. G Quote Link to comment Share on other sites More sharing options...
