Please DO NOT Post In The General Section

From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.


The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.


For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.


Everyone will get a couple of warnings from here on out, after that I just start deleting threads.

Again if you have any questions, PM me or one of the other mods.

        honda's highest compression is 11.7:1. i'm sure with a good tune you could pull of 12.5:1. I'd stay under 12:1 though.

          i would go with what your tuner thinks he can get it running at if it was me. if your tuner is not very good its going to be lower compression, a really good tuner can get the power and reliability at higher compression though.

                    bacically it all comes down to tunning. you could run 13.1 on pump gas if tunned right. id go with something like 12.5 or even 11.

                      13:1 starts pushing the boundary of retarding the timing too much to compensate for the increased cylinder pressure. You can run higher than 12.5 and just lower the timing to rediculous numbers but its counter productive seeing as you may also have to run rich a/f's to help compensate; VERY counterproductive.

                          I've always been interested to see people running 100 or 104 octane Sunoco or other brand gas for a N/A application and what compression ratio they use. There's a ton of info for maximum CR on 93 octane but I haven't found much for 100 octane. Expensive, but still available at some local gas stations around here.
