Going back in time a bit LOL

[Speedy!]

You guys on the forum know I've been working on flex fuel for a while, and had some content for the channel on that. However, I didn't wanna publish it until I understood it myself, pet peeve of mine to see people with stuff on their channel they obviously know nothing about.

SO, even though this was just published, it was shot exactly one year ago.

How timely

I'll watch in a bit.

Very timely, I might be moving to this fuel soon as well. Did you change injector sizes. Last I was tracking you were on 1000/1050x injectors?

So I was under the impression that E85 separated on its own, I didn't realize water was part of the test.

Will E85 separate on it's own if you leave it long enough?

Watched the vid, very informational. You mentioned it smells like moonshine, did you give it a sippy sip off camera. 🤣

Speedy is on it!!! Always bringing us the latest R&D..😂

A really old article, but a couple of key points in there. One is the mention of the difference in knock versus pre-ignition

The research octane of ethanol is impressively high, which is a beautiful thing for high-compression and high-boost applications. However, its motor octane (the more extreme standard) is relatively low when compared to racing gasolines of similar (R+M)/2 octane. What this means is that E85 is highly resistant to knock but somewhat sensitive to preignition, comparatively speaking. (Knock and preignition are two different conditions: Knock is spontaneous combustion in the end gases before the flame-front can arrive, while preignition takes place before the timed ignition spark occurs, typically due to localized incandescence or hot spots in the combustion chamber.) But it's no huge deal: Simply know that when running E85 and other ethanol blends, you need to step down one to two heat ranges cooler on the spark plugs, and watch for other potential hot spots such as sharp edges on the piston domes and chambers.

@Speedy!

I just read a quip about centripetal separation. Absolutely unsure about the validity of it working or not.

My IRL friends are giving me shit about a 15gal fireball in my backyard.
