Has anyone seen a dyno test showing the horsepower difference between 10% ethanol fuel and non-ethanol fuel. I've always had to run the ethanol fuel, but a local station just started selling premium non-ethanol. Just curious.

not sure about that but heres the website that tells ya every place that sells it.

Thanks. Already now about that site. But nobody close had premium until now. I understand that the sled's settings change the timing. Was wondering if the combination of better fuel and better timing makes any real difference.

I think the non ethanol resistor adds 5% more fuel. No timing changes I don't believe.

Non ethanol fuel will make more power and is less prone to DETO.The power increase will only be able to be seen on a dyno tho.the biggest thing is it is less prone to Deto and holds its RON/MON rating longer (doesnt break down as fast).
However due not trust stations that claim they are non ethanol without testing.me and my buddy bought test kits and went around testing fuel in our area and you would be suprised at the results.1 out of the 10 that claimed non-ethanol were actually non-ethanol.all the rest were between 8-10% and some were even higher.
I'm confused. The non ethanol fuel will make more power (I have noticed this) and is MORE prone to DETO. I experienced this when I changed my head and the sled was hitting DETO with non ethanol plug. By going to the ethanol plug the DETO went away.
To answer the original question, go see www.dynotechresearch.com, and don't be afraid to pay the subscription price.
One product we found that helps with ethanol issues is Star Tron. It's an enzyme fuel treatment that stabilizes and prevents phase separation. We use it in everything from vehicles to toys. Some have gained mileage in their vehicles. It even helps rejuvenate old fuel.
Now I'm confused. You added a head and had detonation problems.
So you you changed the plug to Ethanol Plug (+5%) and the deto went away. (It should your drowning it out)
Maybe you need better fuel. Mix in some AV Gas and see if it goes away with the higher octane.
Kind of defeats the purpose of a higher comp head if you add more crap=low octane fuel to keep it from detonating.
The whole range is running rich and you arent getting the full potential HP out of the motor.

We are saying the same thing. I thought TrickedXCR was referring to the non-ethanol plug in his statement, but he was actually referring to non-ethanol fuel. My bad.

doubt it....Ive got a buddy that has run straight ethanol free fuel for about 400 miles and his engine went down at 600 miles. It was a crank bearing though.
88 ethanol free fuel VS 91 with ethanol
So which would be better for our snowmobiles, an 88 octane straight ethanol free fuel or a 91 octane with 10% ethanol? Our local distributor only offers straight ethanol free fuel with an 88 octane. In the past, I've only run the 91.
Thoughts?

Given equal amounts of liquid, there is less energy in ethanol than in E-0 gas, so factoring in phase separation and poor storage traits, if I was standing in front of that pump and having to decide, I would choose the non ethanol fuel every time.
