Maximum Compression Ratio
There is no maximum safe. Every engine is different. Be as smart as you can with your build and back it down from maximum. Or be prepared to tear it down and fix it.
Exactly!
There is as safe Max but it just changes with every combo, that now, the question is answered with a general statement of..... Ratio. And
in and on error to be safe. What can be run and what is run as well as what is available to the fuel tank where the next guy lives is all part of the generic answer that is slightly lower than what could be possible.
Is it possibleto run a 13-1 iron headed engine on the street swill of 93 octane gasoline?
(Young guns and novices, careful, loaded question above!)
But seriously folks, standard pump swill is what we run so......
Many years back, in the MP books, Larry Shepard gave us tips on what to do and how to do it. His ugide lines were oin the safe zone. This way, everyone stays happy. Could you push his published numbers? Sure. Would you be happy. Probably.
But don't complain and ***** when you are not.
