Hi everyone,
Those of you who have built up a Type IV 2.0 with higher compression, what is the safest compression ratio to use 93 octane pump gas? |

I strongly disagree with the above. Go with the CR that your cam dictates unless you know what you are doing. I've built more than my fair share of motors at this point and I still tend to fall within those CR numbers. While all those variables do change what static CR you can run, all the cams I run (WebCam) come with a recommended CR stated.
Deck height, displacement, and head CC will dictate CR. |
