506whp Stock IX turbo E85
All those different blends will vary in octane in accordance to the percentage of EtOH, which is predictable. The range of E70 - E98 should span a range of effective octane from ~100-110.

Leaded race fuel kills O2 sensors, not E85 or unleaded gasoline.
Retuning the ECU for E85 is easy. I did it the basic tune yesterday in a few minutes (literally), and it worked perfectly from the get-go. However, even stock frame turbo cars need a 255lph pump and 850cc/min injectors to be safe.

Theoretically, it should reduce the range on a tank by 25-30%, but I read the actual reduction is typically less. I do not have enough first hand experience with it to either confirm or refute that claim.
From what I have been told by the guys who run it here, your cost of driving is about the same. The E85 is cheaper, but with the amount your burn (I'm sure a LOT due to the sudden heavy right foot disease lol) you come out about the same. I don't drive that much, and I can control my speed so I'm hoping I WILL save quite a bit, while making more power. Double bonus! I should know in a matter of days, my injectors just arrived today
Mileage is between 16-20 mpg (stock or green turbo) with E85 depending on how often you get on it. That assumes you run 26-28 psi.
Mileage on pump gas with alky at 26-28 psi and same turbos is 18-23mpg. Not a whole lot better.
Mileage difference between running 28 psi on E85 and 21psi on plain pump is of course bigger, but comparing that is neither fair, nor logical.
Cost in dollars is very similar, because ethanol is cheaper than premium by an average of 75c.

DAYUM dude nice job lucas does it again
dang you guys got johnbradley on the team too, good stuff
x2 mrfred, premium is 3.99 @ some stores here in FL FTL
def about to covert to e-85 soon.
how is the MPG with e-85

I've read through this entire thread and the information has been worthwhile and very enlightening. I do have several questions and/or concerns that I would like the English Racing Team to weigh-in on.
1. For the ETS 5" FMIC, was any trimming, cutting, etc. needed in order for it to fit properly?
2. What are the benefits of using the MAFTPro 3.5bar system and is the AEM EMS mandatory?
3. What is the "BS" as it was mentioned in the original post that it was removed?
4. What are the benefits of running an electric water pump?
5. Is the BR ported head being used?
6. What is an intake "spacer"?

Yes, the bumper needed some extensive trimming (the 4" doesnt however) because we not only added the 5' core but 3" piping everywhere as well
2. What are the benefits of using the MAFTPro 3.5bar system and is the AEM EMS mandatory?
It removed the MAF as a potential restriction in the system. In the DSM's using a MAF-Translator or MAFT Pro has shown to be worth 15hp or so. You do not need an AEM to convert to speed density using the Pro. Otherwise the MAF-T will use a GM MAF which is larger and is generally placed in the UCIP removing the restriction pre turbo
3. What is the "BS" as it was mentioned in the original post that it was removed?
BS refers to the balance shaft
4. What are the benefits of running an electric water pump?
Less hp loss since the belt drag is not present. This was looking for every last bit out of the car. It requires some custom fabrication to work properly so its not just a bolt on and while the car ran with it for 15k so far its streetability still has yet to be proven in my mind. If it can go at least 30 then its not a bad investment. For roadracing though this might not be the answer.
5. Is the BR ported head being used?
No, this is our "Street Version" ported head.
6. What is an intake "spacer"?
A phenolic spacer between the intake manifold and the head to limit heat soak of the intake manifold and ultimately power loss due to intake charge temp increase.
