I’m confused on this part sorry
I think you meant no.... yes...
It's OK - I speak confuzzle...
In question answer, powerslide the transbrake and shift blue on the wheelspin for max torque!
No. The first question was can you run 85 in stock hellcat.
Yes, you can…
No… it won’t add power. On the contrary, you will lose power
You are thinking NO you can’t but YEAH, it would add power if you could????
My 2018 Hellcat owners manual says "no".
Do not use E-85 flex fuel or ethanol blends greater than 15% in this engine. These engines are designed to meet all emissions regulations, provide optimal fuel economy and performance when using high-quality unleaded “Premium” gasoline having a posted octane number of 91 as specified by the (R+M)/2 method. The use of 91 or higher octane “Premium” gasoline is required in these engines.
With an otherwise stock engine, albeit with an E85 system installed and with a suitable tune along with it, E85 might eliminate any timing retard. This can increase HP and maybe enough to show up on the dyno maybe even at the track.
But you have to install a proper E85 system -- which voids any warranty. Obviously the E85 system costs money. And while E85 costs less than 91 the engine will burn more E85 than 91 octane gasoline. This affects the payback from switching to E85.
This is wrong.

I had to look this up, then I had to post this if only for the pic:
Does E85 Damage Engines - Or Injectors Or Fuel Lines?.

Great post
Care to elaborate?
He asked 2 vague questions. I answered both. I was vague with my responses but both my answers are correct. You definitely CAN run e85 in a stock hellcat and you definitely WILL NOT see a increase in power
Dude didn’t ask what his air fuel ratio would be, or need to be to be safe for maximum power at wot, or how or what to do to get it there
You must be talking physically not technically. Which is non productive.
You can but it wont work so No. He needs larger pumps and injectors and a tune to run properly which would not be stock.
After said modifications he will gain hp, 50+/-
Read my signature, i know what Im talking about.

Damn, seems like people just look for reasons to argue.
WILL A HC RUN ON E85? YES, BADLY BECAUSE IT'S NOT MADE FOR IT BUT IN A PINCH IT WILL RUN.
The reality is don't do it without a conversion, so Sick is right it will run, he wasn't saying to do it. RedKey says no because it's the equivalent of using machine oil instead of motor oil, 87 Octane would probably be preferable to E85 and your car will sound like a drummer having an epilithic fit on 87.

So that brings up the question I have had for quite some time:
Just how lousy is the 15-50% (lol) gasoline that they are blending with the corn liquor?
After all the refining they have to do to make gasoline how low can the octane be and it still be considered gas?

Would expect the gasoline used to make E85i is the same gasoline used to make 91 E10 or even 91 ethanol free.
With 91 to get the octane iso-octane (octane rating of 100) is used in some ratio to n-heptane (octane rating 0) to get the desired octane rating. If ethanol is being added iso-octane content is reduced as the ethanol boosts octane some.
With E85 (with 51% to 83% ethanol) I'd have to believe little to no iso-octane is used. All the octane comes courtesy of the ethanol.
The ethanol brings octane with it. But it can't make up for lousy gasoline, even if the gasoline represents just 49% to 17% of the E85 blend. The gasoline in E85 plays a critical role in how the fuel performs. One function gasoline performs in E85 is to improve cold start behavior. Ethanol doesn't do well in cold weather. Which is why the ratio of ethanol varies from 51% (E85 winter blend) to 83% (summer E85 blend).
If the gasoline was lousy cold starts would be lousy and acceptance of E85 would tank (no pun...).
