11-1 comprssion, 93 octane and spray Im building a forged 346, im looking to use 11-1 static compression with a 64cc head. Im not sure of dynamic compression as im still researching parts so I dont know what cam im gonna go with. What would be the highest shot I could run? Ill more then likely use a stand alone fuel cell later but now what are the limits on 93 octane. The reason for the higher compression is that I want a motor that is pretty stong off the bottle but to have the bottle if I need it. I know there are alot of factors involved in saying XYZ is this compression for this and ABC is the max for this. Im looking for a general rule.
the shot would be limited by the strenght of the motor and timng....you might be able to run a 250 whp shot but only be able to run 20* of timing. which would probably hurt you're NA numbers..or you might be able to run 125 shot and 118 octane and not affect your NA timing that much, not giving up any or much NA power ....the question is how much do you want to run or how much are you willing to give up NA to run it ?

ya im looking at the MSD timing twister. Its designed just for mod motors and will retard timing when a nitrous kit is activated. I will be investing in a stand alone later but wanted to know the limitations.
