Since lower compression engines are needed to avoid detonation when boost is present, could you then get by with higher compression and boost if you adjust to higher octanes? Whether race fuel or Ethanol (E-85)???? I'm talking compression levels between 10:1 to 11:1 ??? If so, would the boost pressure (lbs.) have to be somewhat lower?


Yes, with the right octane and cam you could run high static compression, but with relatively lower boost than you could with lower static compression. Is your motor already built with high compression and you want to run a blower?
