E85 on 997.2 C2S. Possible?
Hey guys, I've done a good amount of searching and can't find anything conclusive. Would it be reliable or even possible to have our C2S's with 3.8 DFI to run E85? Has anyone done this? Thoughts?
I'd love to get input from tuners or higher educated individuals who've dealt with this prior.
I'm interested in having this done and adding IPD Plenum and FVD Street Sport to have it all tuned together. Please chime in.

It's long been thought of as "poor man's racing fuel. It's all way over my head, but has something to do with running cooler and potentially getting more power out of forced induction systems. That's probably a gross oversimplification.
I don't know what the point would be in a 911. Especially a naturally aspirated one.

OK. After reflection, it appears that you are attracted to the burning qualities of Ethanol.
When I lived in Brazil, the majority of cars were "Flex fuel" cars. My 2006 Peugeot SW
was one. For sure it felt faster and a bit more powerful with "Alcool" as they call it there.
The down side was that the mileage suffered quite a bit. Most cars and trucks there are
Flex and Diesel is mostly banned. In the USA, it is difficult ton find fuel that is more than
80% Ethanol but they do exist. Now comes the question: will its use do damage to the Porsche engine?

The ethanol blend runs cooler for most FI cars but The better note is that you can advance timing a tad bit to make more power; and there’s less chance of knock than with regular octane. There are many cars on the market that have flex fuel kits being offered on NA vehicles and they are making good gains for the money.
I’d like to save myself from spending ridiculous money for other bolt ons to achieve similar power that I will with ethanol. Sure it, does go through fuel faster BUT it’s also cheaper. And the best part is that I have one of the best ethanol stations in SoCal at .08 of a mile away from my house so the convenience for me is there

Sometime in the last year or so excellence magazine did an article about using ethanol in Porsches. I don't remember the advice or conclusion but maybe you can locate the article for another point of view. Their web address is www.excellence-mag.com

Here's another interesting exchange from Renntech

- looks like changes will be required throughout much of the fuel system to try and do this, not just stopping at an E85 station and filling up.
