06 Gix 600 w/ Some Testing
1 Attachment(s)
Check out these interesting results from an 06 gix 6 that they were testing out at wcw. I'll let the graph speak for itself. Check out that dip with the regular pump fuel and how the race fuel alone smoothed it out...pretty interesting.
Pump Fuel - 108.7 U-4 Race Fuel - 112.2 MR-9 Race Fuel - 114.7 MR-9 w/Leo Vince slip on - 115.7(I don't have the graph, but thats what it made.) |
What are the octane ratings for each fuel Joe?
Are the motor's internals stock? |
the octanes are problably in the 104's and higher for those really nice burning numbers...
|
Actually, the octanes are quite lower than one would think. U4 is 92 and the MR9 is 87...but they're both leaded oxygenated fuels. Stock motor.
Check it out. |

The oxygenation
|
Joe, does that bike have a PC? If so was it mapped for each fuel?
BTW, Ron needs to upgrade his dyno... |

i was told that NJ oxygenates the fuel in the winter to keep stuff from freezin up and what not. and when i reaced MX i was told to either run race gas or add octane booster in the cold months because of the oxygenation, so was i fed a line of BS or os it different with the 4 strokes than with the 2smokes i use to run.?

I guess it just depends if Ron is going after that business... |
Octane ratings are just resistance to detonation. Race fuels with proper tuning make more power through more energy in the fuel. If you think about it, higher octane slows burn....slowing power made. With today's 15K redlines, higher octane really isn't the answer, sometimes it's counter-productive.

ya i know about the octane situation, if you try to run race fuel in most stock 4 strokes it usually makes less power, but that's mostly with dirtbikes from my experience, i haven't messed too much with race fuel and street bikes. but i would think it would be the same situation since the basic design of a 4 stroke is the same whether it's drit or street

There's a big difference in the quality of fuel you can get out of an 87 octane pump fuel and MR9.
But for all intents and purposes yes, you only need as much octane as is necessary to keep your engine from detonating to make max power. |
Race gas is usually quoted as Motor Octane and pump gas is the Research Octane + Motor Octane divided by 2. Motor Octane is a lot lower then Research.
