E98 Information wanted
(OP)
I am based in Minnesota, and need some information about this fuel.
We are currently running a Mitsubishi 4G63 with a 71mm Turbocharger on it. We were running E85 last year on a 61mm turbocharger and made 541 wheel horsepower on 25lbs of boost. Beyond that the clutch was slipping, so we called it a day and ran 11.0 @ 135mph. No knock.
About 2 weeks ago a fuel called E98 was brought to our attention. We did some searching and found a local distributor for 3.20 a gallon.
The fuel system is designed to run E85. Everything is okay to run it, and it has been running E85 for over a year.
My questions:
1. What would the Octane of this fuel be? E85 is 105ish octane, and I know from dyno experience that it takes a LOT to get it to knock.
2. Is it going to overly corrosive? The car has an aluminum cylinder head, and this is going to be a mixed street/strip car.
3. What are fuel consumption requirements going to be over E85? I'm guessing there won't be that much difference between the two, but I'm sure Stoich is different.
4. How hard is this going to be to ignite? Am I looking at an upgraded spark system? It does fine with E85, but it kind of stutters when it is cold (doesn't do this on VP C16), and I'm thinking it might be too cold of a spark or a spark blowout type deal.
Mainly I am worried about Corrosion.
Thanks!

RE: E98 Information wanted
I would also expect the sums on octane will be reasonably accurate, but it does not always follow that a mix gives an octane equal to the mathematical average.
This site will provide all the basic data you need.

I think it will start as long as its over 40* outside on E98. Below that it's probably iffy.
One guy not too long ago tuned max power on 110 Gasoline and made 601whp and then put in E85 and made 663whp.
There is a 2.3 liter motor running on E98 running in the 7 second range in the quarter mile now! (Honda)
How is the cooling of Ethanol as compared to Methanol? I know with Methanol you don't need to run an intercooler in a drag racing car. How close is Ethanol to this?
Thanks.
RE: E98 Information wanted
If so why do you ask questions it answers.
The 2% is almost certainly water. Pure ethanol is very hygroscopic and quickly absorbs a small amount of water from the air.
