Safe dynamic compression for boost?
I am getting conflicting results from my research as to what is safe and what is not for pump gas. I think the confusion comes from whether or not people are refering to their dynamic compression ratio with or without their boosted pressure influenced on it.
I have calculated my dynamic compression ratio at 8.1:1 and with every bit of information available using the wallace racing calculator I got 12.6:1
What octane is this safe to run on and should I rely on a meth/water injection to be safe or would it be just additional protection?

Give us some details, bore, stroke, rod length, SCR, altitude, and intake valve closing ABDC (mention if .050" values or what).

Yes sir, ayousef.
bore:4.03"
stroke: 3.75"
rod length: 6.0"
SCR:8.162
altitude:100 feet
ABDC: 66 (http://www.compcams.com/Company/CC/c...?csid=204&sb=2)
the two calculators I used for dynamic.
