Fuel question
I am at the track, car is tuned on VP C85 and the car went several rounds today and we are down on fuel. There is no C85 available and a buddy has some E98 in the next pit. How much is it going to affect the tune if I put a few gallons of E98 in?

Re: Fuel question
How many more passes do you plan on making? I'm also using c85 and 10 gallons has lasted me a dyno session and 14 passes so far and I still have just under half a tank according to my fuel gauge.
I'm sure 3-4 gallons will get you 10+ passes if that's what you're concerned about.

Re: Fuel question
thats a big difference, you would want to add probably 5% fuel atleast to be safe for the first run when last resorting to something like that. Log it, Fix it.

Re: Fuel question
its math.. one c85 is 85 parts ethanol and 15 parts some type of fuel and additives, e98 is 98 parts ethonal 2 parts some other crap. if u want to make home brew e85 then mix 85 parts ethanol and 15 parts 93 or some type of race gas. or for 5ish gallons i think its 4.5 e98 and .8 fuel.. im converting off litres sorry. its 17 litres e and 3 litres fuel. i make my own e all the time cause we dont get it here in canada. as long as your not off more then like 5 points ethanol either way you should be fine.

Re: Fuel question
We actually just cut down the E98 fuel with 87 Octane to make it E85. Added 13% 87 Octane to the E98 and it worked great, raced all day and the car even went a bit faster.
