I am not looking for this. Unless this is what also results in my actual goal.
What is the limiting factor on the motor I am building? Cylinder head sealing? The block? The rods? The pistons? The crank? The mains?
If it is cylinder head sealing or the pistons/rods I think setting a hard limit on cylinder pressure and tuning for max power while staying under that limit might result in a motor that makes a large amount of power and stays alive.
Currently my timing is in the 16-20deg range depending on rpm and that is backed up by the dyno and what most other people seem to run. I see nice gains going from 16-18 and much smaller gains above that. What should that timing look like at 30psi? How about 40psi? Just using the add timing as long as there are good gains might not put you at the same spot at looking at cylinder pressure and keeping it under a certain number.

Very interested in this also. A mid 9 sec 5.3 approx 4700 race weight I think was at 11 deg timing. As in other post sbe 5.3. BTW been following you since the old Honda bike vs turbo Silverado vid days. You're an icon. I'm new here but not new.
