What sort of cylinder pressures occur under varying boost levels ?
Im curious to kinow what cylinder pressures are occuring under say 6 psi boost and 15 psi boost ... on an LS2 or LS7 motor ? I tried to find a chart online but couldnt locate anything.

Basically, low side 1200 PSI - high side 2000 PSI -
here is a BMEP article/formula ofcourse the tune and setup are some of the factor to consider when considering a "safe" area in referance to cylinder pressure
There is no formula for this. It must be derived from a pressure transducer in the combustion chamber.
A ballpark number can also be back calculated from engine torque
After all, pressure * piston area = connecting rod load. Rod load * distance from the rod centerline to the crank centerline = instantaneous torque.

Ball park figures were already given. See post #2
Have you run your engine on the engine dyno? Probably not and 99.9% of the guys on this board have not. It would be pretty hard to get anywhere with in a baseball field of the correct values with out the correct data to back calculate from.

No, I run a single cylinder Hydra engine on the dyno for my job, that's how I know that. Cylinder pressure on an LS-engine is not very important for me
