What are the gains that you're looking for that you're willing to trash your car?
i’m not willing to trash it first off, like i said i’d just be ready to fix what might go wrong. Secondly, i’m not really in it for the power, just want to see how it would run
E85 makes LESS power (by about 1/3) than gasoline unless you're running under extreme amounts of boost because it isn't as prone to detonation. That's why the guys with the boosted exotics run it.
Not sure where the 30hp figure comes from unless he is talking about the newer twin turbo C63 with a tune (which would make sense). Naturally aspirated engines will see no benefit - just the opposite. Your C55 will probably feel like a C230.
As to damaging the engine/fuel lines/injectors/etc., it should be a new enough car that it should have ethanol resistant rubber and seals, but I could be wrong. Just as an anecdote, I rebuilt the carburetor once on my 1978 Trans Am and didn't use the ethanol resistant parts. Worked great for about a week then wouldn't start. Took it back apart and the accelerator pump had completely disintegrated. That was 10% ethanol...

Reason: typo
30hp comes from the vendor who is selling the kit, they were talking about an NA C63. Took me 15 seconds to find that before I replied. Took me 15 more seconds to find many dyno sheets showing 10 to 15 to 20rwhp gains. Here's the most thorough, this is with a C6 Z06: http://v8muscle.net/E85dyno.html
In my more educated opinion not really worth it unless you have every single bolt on including cams and are trying to squeeze everything out of the M113. You also have to test your fuel each time you fill up with a special tester to make sure you are getting a proper blend, need to scale your fuel system to handle an additional 30% volume and long term storage (alcohol is hygroscopic).
Huh. I did some reading up on it and I stand corrected - thank you Fantomas. I don't think I would have ever really looked that much more into it. Apparently there are gains to be had for na engines.
What I had previously read still remains true: E85 only has 2/3 of the power of gasoline, but when presented with the larger amounts necessary to make a stoichiometric blend, there are gains - albeit small (1-2%). Octane varies but is in the 105-110 range, so less detonation so you can run more compression/boost. Works best with direct injection over port, but I could see maybe 10-20hp on our engines based on what others are getting on their LS Chevrolets.
May still be more of an investment than other bolt on power adders for the same gains though.

Best of luck really, but I wouldn't risk it just to "see how it would run". You should have a financial gain, power gain, something else gain, to make it worthwhile, no? Just think about it, is all I recommend.
An m113 will make very close to 20whp and 20lb ft on e70 to e80. It will need bigger injectors. A reflash and tuning for those injectors. Will probably make more on an E85 tune.
As i stated in another thread about this: the stock ME (ECU) does not hold more than one tune. OR have the ability to run a mix(like modern e85 cars do) so not ONLY: do you have the change your entire fuel system, you HAVE to:run e85 ALWAYS after you do it(unless you put the old tune back on) You CANT mix them either.(stock ME wont read that correctly) Theres not enough stations around to fill up on, it costs a good bit more than gas, AND uses 40% more fuel! so like 10MPG's! If you want temporary power: get NOS, it can make 10X that power for short bursts.

Yes it only holds one file. You use a flex fuel controller, from advanced fuel dynamics. All you need is a bigger injector from a m113k I know this because I am running E85 on my Me2.8.

Also I pay 1.90 to 2.15 for e85, when 93 is 2.95 to 3.30$
