I'm seeing a difference in the percentage of alcohol in the local pump E 85 I use to race with when testing it, it seems to gain alcolol when it has sat in the plastic jugs during the winter from 2 to 3 %, from 85 to 88%
I bought some 98% ethanol medical alcohol and want to make all the race fuel the same by adding more ethanol to what I have.
What are your thoughts on this and what do you think of making it 90% and will I need to jet up or down
I haven't done much testing on the jetting on my carb. yet, shame on me
The car does run very consistent with the E85 pump fuel no matter if I run the 85% or the 87% with no tuning changes .I will and do mix them in the 7.5 gallon fuel cell at the races while racing after using up each jug
I'll add another post to the bottom on this
