More Is Better
A 9.8:1 compression engine, at 18 PSI has an effective compression ratio of 21.8
My 11.5:1 compression engine, at 13 PSI has an effective compression ratio of 21.67
In other words, using the above numbers, cylinder pressures should be nearly identical.
So...I think I can run this setup at a boost not to exceed about 13 or 14 PSI and be safe...at 13 PSI I'll be making the same cylinder pressures as someone running a 9.8:1 engine with 18 PSI of boost.
