Full mod 32cc read case obr engine

[Crazy4baja]

Ok I have a gallon of 110 octane and a gallon of 91 octane if I add 1 gallon of 91 to 110 does that break it down to 100 octane?

What octane did you tell them you were going to run?

 

[Crazy4baja]

I thought 110 was ok but it's not

 

[John Parks]

I would just run 91, your best bet is to call obr. You don't want to burn an engine up trying to get .5 hp more.

First you need to calculate the percentage of each fuel that will be in the final mixture. Then, use this equation to find your octane:
( [ % Fuel A ] x [ Octane of Fuel A ] ) + ( [ % Fuel B ] x [ Octane of Fuel B ] ) = Octane of Mixture
Here’s an example. Let’s say you mix 3 gallons of 110 with 2 gallons of 100 and you want to know the octane of the resulting 5 gallon mixture.
The percentage of 110 in the mix is 3/5 = 0.60 (60%).
The percentage of the 100 octane fuel in the mix is 2/5 = 0.40 ( 40%).
Plugging the information into the equation:
(0.60 x 110) + (0.40 x 100) = 66 + 40 = 106
So the octane of the resulting mixture is 106.
