I'm cannot fine e85 with in two hours driving distance. My local speed shop has 110 octane unleaded race fuel. I was wondering if the race fuel will give me the performance boost of e85? I have a Jb4 I am guessing map 5 would be the best to make use of the extra octane? Would I mix the race fuel like the e85 about 35% race fuel 65% 93?

thanks I have used the search and have read some older post from 5 years ago but it seems the jb4 has changed and now the race fuel is available unleaded. thanks again

For race fuel I would use map 7. I use map 5 when mixing e85 with 91.

OP race fuel is another option, obvisouly a much more expensive one.

You can use map 5 ... If you have the supporting mods(downpipe,intercooler and charge pipe) use map 7

is 30% a good starting point for the mixture
