Gas?

Even if it does, the difference between 89 and 94 isn't going to be noticable to the average street rider. Besides, how many of us are riding around at 12,500+ rpm all the time? It might be an advantage at the track, but on the street you're just throwing money away IMO.

my bike dyno with two diff grades of gas and i get two diff hp numbers... when my bike is tuned to 93 octane i put down a little over 110 to the wheel with the lower octanes such *** 87 im only around 106. same is said for race cars and so on. now the compression of our motors is not high enough to run say 107 that is excess but 93 and 87 there is a hp diff. ![Icon Doh](https://cbrforum.com/forum/images/smilies/icon_doh.gif)

like i sid before i had my bike tuned for 93. well im a little foggy sometimes and had thought maybe i still had 87 in the tank with the stabilizer since i had the bike tuned right at the beggining of the season. so i put some 89 in and guess i was right. my motor was pingign like crazy . back to 93 and she feels like a solid beast!lol oh and i think we should close this thread already. i mean DAMN!lol![Icon Playing](https://cbrforum.com/forum/images/smilies/icon_playing.gif)

the grade of gas is just the resistance to detonation, its no indication of energy in the gas, just a measurement, like temperature

higher grade gas ill only produce more power with the correct tune, youd either have to advance your timing or turn up boost pressure if you had a turbo or sc. the reason this works is because higher grade cause actually needs more to ignite. so unless you had more air and fuel in your combustion chamber adding a higher grade gas would do absolutely nothing for your horsepower.
