take motor one and motor 2…
motor one has 9.5 compression, motor 2 has 12.0 compression.
both motors are exactly the same except compression ratio (yea ik, but lets just say they are the same… fine. they have the same brand parts, but the low comp pistons and hg in motor one, regardless)
which motor should make more power n/a? obviously #2 (ask anyone who has driven a turbo car with low comp w/ a blown coupler)
now add boost and a good tune to both motors. lets say 12psi each. which will make more power under the same conditions? again, #2
a higher compression ratio in either case allows you to get more air and fuel in the combustion chamber…
low compression is easy to tune, dont bitch out and go low comp. jack that comp up!
