what does it take to run e98?
#16
Bumping this back up. Found a local supplier that will sell me e98 for around $3.20-$3.50/gal. I've been told that I need to run e98 really fat, like 10.8/1afr fat and since I'm now high compression, I can't run really anything besides low teens for max timing, even on e98. Does this sound right? On my stock block I was running 18* up top with 37psi and made 630whp.
Need some direction from people who have tuned on e98 please.
Thank you.

There's an ethanol plant down the street from me. I called and left a message to see if I can get my hands on some E98, if they carry it at all. If they do, might be calling Aaron at ER and stepping up to the 98.

If you live in a cold climate, or seasonally cold, be ready for some rough starting. Probably best to buy the E98 and mix it with some 91 as others have suggested. Most of the E85 tuning stuff i have seen suggest ~ 8.0:1 AFR for WOT tuning. On an 02 calibrated for gasoline lambda this would read as 12.1:1 or so.

Then who were you talking to? Unless you're talking to yourself, trying to get that post count up. I'm looking for info on timing/afr maps, not where you get your e98 in TN.
Anyways, I am just wondering why there is such a big difference in the info I got in person vs what I'm getting back in here. Hes also running 9.00 in the 1/4 though, so probably a little different ballgame than other setups.

I'd call it thinking out loud, as in you sparked an idea in my mind to look local to find E98 and did and figured I'd make it known for anyone local who was reading this thread. But since you went out of your way to make a snide remark I figured I would too. I could care less about post count.

You are probably going to need to get it on the dyno and just see what it wants. Cross linking this from the E85 sub forum MIT study on Ethanol as a fuel,
