Static/Dynamic compression ratios/ boost and 93 octane?
Well after doing some digging tonight I discovered that my compression ratio may actually be a bit higher than I had originally thought.
I thought it was stockish around 9.5:1....im now being told its probably more like 10~:1.
Anyways, I was looking into static vs dynamic compression ratio and theoretical boost limits on 93 octane.
According to the calculator my Static compression ratio is 10.2:1
Your dynamic compression ratio is 8.25:1 .
Your dynamic cranking pressure is 165.44 PSI.
Your dynamic boost compression ratio, reflecting static c.r., cam timing, altitude, and boost of 18 PSI is 18.35 :1.
V/P (Volume to Pressure Index) is 110
These are approximate numbers but you get the idea.
I saw somewhere that 93 pump gas would support around 20:1 dynamic compression ratio.
Is there any truth to this?
