So I did cr test while eng. was in temp ranges early last month and got much higher psi readings then what this is showing. Is "Dynamic cranking pressure" what my cylinder should be in psi with cr tester. Using this website and just putting 0 boost in. And all my specs I am getting dynamic cranking pressure 217psi But when I took my Oreillys cr tester with engine hot I got 245-250 with 6 cranks. he also states on website to take cr when eng. within 140-180 Deg. F. Am I missing something here? also has me at Dynamic cr ratio @ 10.23:1 with my IN valve closing 44.5* ABDC. Thanks for any help.

what is "this"?

 

What I'm saying. Could there possibly be something wrong with my IN closing ABDC notes/#'s cause the Dynamic cranking pressure does not match up with this when I did an Actual Cr. test. Playing with the Calc. I was only able to get numbers up by messing with IN valve closing ABDC to match what I saw on a Cr test. (PSI) My notes say I have IN closing 44.5* ABDC which dropped my Dynamic cr to 10.58:1 and my static cr is 11.69:1 and it says my dynamic cranking pressure is like 224psi - 212psi // Now when I did an actual Cr. test My gauge read 250psi ... sorry does this make any more sense?

 

Calculator vs real world are very often skewed
