TO OR NOT TO USE <<e-85
I bought my C-320 in Aug. of 2018 (Limited crossfire with a wagon skin) in other words the C-320 has the same engine, transmission, and rear end as a limited crossfire.used high test as recommended in July I started using reg gas yes 87 octane after three or four tanks full and about 1000 miles, and after much research I added some E85, 3 gal to a tank full of reg. the power increase was very noticeable , by adding 33% E-85 every thing in the fuel system is safe, google it and ask people that race and want more power ,,no people that sell or just work on cars., one of my source's is a Ford engineer , one is a nascar mechanic, mercedes shop and others,,, power not gas mileage ,, maybe this is a cheap was to gain hp in the limited as well as the srt6 jim
Re: What did you do to your Crossfire today?
Thanks Jim, that is really good information to know. I may just try that in my SRT6. I have seen your slips listed (I have to skip by the numerous slips you have there to figure out my car's "rank" in the "fastest" category). Didn't know you sold your car. Any idea if an E55 with an EC tune can handle the 33% E85 without a retune? My SRT6 is down right now while I investigate a boost loss issue, so I am bringing my E55 to the track in 9 days. Could use the additional advantage! ~Crystal

Hopeully my SRT responds well to it.
Also wondering if haveing a tune and pulley would effect this...
Re: What did you do to your Crossfire today?
My next trip to the drag strip i was going to do the same thing,, if you have some old time slips to compare it to.
full tank of gas is to heavy use maybe 5 of gas and 1 &1 1/2 of e 85 the % of the ethanol is + to the E # e 10 is 10% ethanol and e-85 is 85% so set yours around 33% and your car can take it not sure with a tune and pulleys my C320 has a afr reading of 10.2 and with the 33% it reads 11.8 ,,which is good NOT LEAN my black V8 the afr's were in the low 12's could not add anything over e15 in it. good luck,, maybe we have come up with some cheap hp and only need it when we want to go fast... jim

Re: What did you do to your Crossfire today?
alright I’m gonna go be a guinea pig and put 7 gallons of 91 and 3 gallons of e85. And see what I can come up with. It’s probably gonna run slightly leaner then what you’d typically want. Since e85 requires more fuel to burn. But 30% seems doable.
Hopeully my SRT responds well to it.

I was led to believe E85 fuel isn't compatable with our fuel systems. Did I read something wrong on this topic? .
Re: What did you do to your Crossfire today?
I was told by two mercedes mechanics ( both race e55 and e63 both mix e85 they use 35% because both have bigger injectors they said only if you go e85 only do you need the o-ring changed on the bigger injectores and remove the fuel filter/regulator and add a manual fuel regulator hoses are ok.. he is talking about Mercedes not the crossfire ???did they use the same hoses on mercedes and crossfire ?? in a few months we will know how it works ,,track time and pump and hose inspections, jim

Re: What did you do to your Crossfire today?
Have a larger supercharger inlet, throttle body and DCAI coming from Needswings for Jim's old car (My new car) installing that along with a supercharger pulley and then off to the dyno for some tuning. Looking forward to dyno numbers and the track as soon it's warm enough.

lf your afr's are low enough maybe add a gal of E-85 anything over 12.3 is too high ( for those that don't know)
thanks for the update jim
Re: TO OR NOT TO USE <<e-85
As far as the ME2.8 can handle it would be up to a maximum of 40% E85 safe without adaptive tune. The Bosch is capable to handle that. As for 100% E85 you’ll need to get a tune. In Europe many running E85 to save cash at the pump. We have ridiculous prices. For those who say it will kill the engine well back in 2004 Mercedes made a C320 sedan FFV. FFV as flex fuel version and have same internals as our N/A. I crawled diagrams parts list etc etc and the main difference is the Bosch ME2,8 had a different fuel map and bigger injectors. On my N/A I’m on the work of a conversion. The only thing needed is specific injectors, a tune and AFR reading. That’s my 2 cent for doing it good. Some uses piggy backs and it work but I don’t like to trick the ECU. Regarding fuel lines, and seals they all are from NBR and therefore E100% résistant.
N/A would need 240cc injectors, for normal driving application or 300/330cc injectors for racing use.
SRT6 would need 550cc for normal street use and 730cc for racing application and powergains.

Re: TO OR NOT TO USE <<e-85
for almost 5 months now i have added 33% E-85 to my C320 (same motor as limited) i had two encounters with two different limited crossfires, one fron dead stop at red light . ran for about 100 yds I was ahead all the way. the second one was two weeks ago,, we were on I-95 doing 60 ,,,up to 100 i won again. i can only say it is the 1/3 E-85 that i have been adding, both cars limited and C-320 weigh 3400 lbs and have the same engine, transmission, and rear end (327)
I am still modding my V8 crossfire, and making test at the track after each mod,,, so far it is V8 as most know i ran 11.78 next will be 2.5 down pipes from engine no cats to 3" exhaust will have a 3" flow through thrush in the middle( to reduce the noise),, to my SRT 6 muffler.

To john, the only problem I’ve seen with doing the FULL e85 with the tune (and changing to larger injectors of course) is that from then on you HAVE to only use e85. You can’t switch back to regular gas unless you get a retune for the car.
Niw this points me in the direction of the kits that companies make to convert your car to e85. Doesn’t require a retune because the kits run sensors for e85 % and they have PWM changers that run inline with your injectors to increase the PWM single to use the correct amount of fuel for e85.
With that ^ you can use pump gas or switch back to e85 on the go. But... I don’t know any draw backs to it and would like your guys input.
Also AMX I have been using 30% like you had said and I do notice a slight improvement. Especially in the mid power range.

Re: TO OR NOT TO USE <<e-85
I use Shell 91 or Nitro 93, no ethanol in it, anyone using regular gas in Canada gets 10 to 15% ethanol, to maintain a 10% across the board ethanol usage in gasoline.
Gas with ethanol has a shorter shelf life so you have to add Stabil or equivalent when storing your car. Ethanol does cause damage to your car no matter what they say and gas wth ethanol gets poorer gas mileage, dries out rubber, any water in it causes corrosion, if you had any water in your gas tank it will get absorbed by the ethanol.
I prefer my ethanol in single malts, beer or whatever.

Re: TO OR NOT TO USE <<e-85
December 2007 Energy Independence and Security Act signed by Congress and the President, which requires the use of 15 billion gallons of renewable (ethanol) fuel by 2015. In 2007 about 6.5 billion gallons were produced. 2007-2008 Surge in individual states mandating the use of 10% ethanol E10 gasoline.,,
they wanted 40% but President Bush, a oil man from Texas, said no ,he would sign off on 10% ,,not 40 %
yes you can still get ethanol free at 20% higher price,
so David please don't use any ethanol in your car. jim
Re: TO OR NOT TO USE <<e-85
for a few other facts:
In January 2011 the U.S. Environmental Protection Agency (EPA) granted a waiver to allow up to 15% of ethanol blended with gasoline (E15) to be sold only for cars and light pickup trucks with a model year of 2001 or later.
In 1896, Henry Ford designed his first car, the "Quadricycle" to run on pure ethanol.[27] In 1908, the revolutionary Ford Model T was capable of running on gasoline, ethanol or a combination.[27]
[28]
[29] Ford continued to advocate for ethanol fuel even during the prohibition, but lower prices caused gasoline to prevail
As of 2005, 68% of American flex-fuel car owners were not aware they owned an E85 flex.[9]
[10] Flex and non-flex vehicles looked the same. There was no price difference. American automakers did not label these vehicles.[10]
[44] In contrast, all Brazilian automakers clearly labeled FFVs with text that was some variant of the word Flex. Beginning in 2007 many new FFV models in the US featured a yellow gas cap to remind drivers of the E85 capabilities.
not everyone agrees that it could or should be used in a crossfire I for one think 33% could be used if not all the time then at least on race day. I am not telling any one to use it. read everything you can before you do. here is where it was posted in years before. jim

Re: TO OR NOT TO USE <<e-85
I am not the first , in fact our government made all oil co's. add E10 to your fuel (that's 10%) and E85 is 85%
