How about you prove everyone wrong. Empty the gas tank and fill up with your regular 92 or 93 octane. Run it for a bit and then put the bike on a dyno. Empty out the tank and fill up with your "super" blend and repeat the dyno test. Be honest and post up pictures of the two runs to show the "performance" increase.

I don't know what is so hard to grasp. if you regularly run 93 and drop it to 91 you will probly notice a difference unless you have a dead ***, so what is so hard to accept that there is a difference between 92 and say 98? Ill say it one more time, I'm not saying anything about running 105 except as a mix ( 1 1/2 gallon in a full 5 gallon tank).
I don't have a dead ***, I can tell a difference, and a pretty good one at that, my head is really f*&(king with me to imagine the benefits I claim, I really need to check into Terrel asap and get on some Xanex or something I think I'm loosing my mind. I don't know if or how much actual HP (if any) is gained, but it runs a whole lot better.

As I said earlier, in the post that you chose to ignore,.... he has a canned map in there that is likely favorable to the higher octane.

It's really not that complicated.

Advancing the timing does not always give you hp. People think more advance gives you more rpm WRONG it does not. You guys could do your self a favor and do some tuning research. Then you will save some money by NOT buying race fuel and other gimmicks that claim hp and mpg.

I had one cam (SE 204's) that actually gained power from taking away timing. But that was against the norm, that cam has +8 out of the box built into the cam.
But in many cases, adding timing will indeed add power (not rpm). The tuners often add timing til it pings then back off. High octane fuel allows them to push that limit a lil farther.
The only way to find out is to get it on the dyno and start playing with the AFR and Timing.
There is a place for high octane and don't try and say that there ain't.
But if you aren't playing the 1/4 mile timeslip game, it's best to tune it for the fuel available conveniently.

You cant tune in compression! And thats what it takes to use octane.

But back to the issue we were all responding to at the begining of this thread; I think you would agree that your engine needs to be tuned to benefit from 100 octane.

If there is more boost, isn't it compressing more fuel mixture into the combustion chamber? BOLD dosn't make you right.
