E-85 383 LT1 Questions?

at a relitivly low 10.5 to 1 you can just put in 4 or five gallons of e85 and top it of with regular unleaded 87 no mods needed will still net you a few ponies save a few bux and not a bad hit on MPG ether . you will need higher compression or forced induction to take full advantage of e85.

First off WOW e85 is cheap by you, i just paid 3.66 a gallon here in central florida.
now e85 isnt easy to get where im at so im kinda hating having to alwasy worry about running low on fuel on trips but for power/durabilty i love it. For a everyday driver i hate it. If your not a high compression big hp guy i would just stick to 93 and make it simple.
dont know if i helped you any but ya there ya go

In Florida it is pretty limited, there are only 4 stations between Tallahassee and Orlando. The other constraint is that "e85" can mean anywhere between 70% Ethanol and 85% Ethanol. Different stations use different suppliers, and as a result can have different mixes.
I recently took a road trip down to Orlando to have access to an AWD Dyno, and had to continue adding fuel to my tune as I continued to move south. My OL Fueling Map required almost 10% additional fuel on the big end by the time I got my car on the dyno. It is definitely a practice in patience, because if you fuel up with e85 from multiple stations, you will be adding random variables unless you feel like testing the ethanol content each time you fill up.
To the OP: I will echo everyone else's feelings regarding not being able to really see the gains that e85 offers with your current setup. e85 burns cooler in the combustion chamber, has cooler EGTs, and is less likely to detonate. That is what allows you to run more timing (which creates more torque).
Switch to forced induction, and that is where the addition of e85 will shine. I am able to run 25 psi on my turbo car, versus 18 psi on pump gas.
I don't have much experience with tuning e85 on N/A cars, let alone anything but opposed-4 cylinders anymore, but I don't feel the ends justify the means in this case.
Unless you tune yourself, you are looking at the cost of tuning, injectors and fuel pump at the very least.

adding E85 isn't the same as dumping 112 octane race fuel in. if it was then you could just go to the pump and fill up with E85 and be just fine, which isn't the case. lol
14.7/1 for E85 is very LEAN.

Nitrous2fast, the answer (you declined to answer) is that E85 stands for 85% ethanol and.... 15% GASOLINE!!!!
So, explain to all of us ignorant fools how mixing in more gasoline is going to cause problems with stoiciometry oh mighty one.

so even if the computer ran the mixture at 11.0/1 with a tank full of E85 you might as well kiss that nice engine you just built good bye...
If it was as easy as just filling up with E85, everyone would do it... oh mighty one!!!
Oh and its not about mixing in more gasoline it's the large amounts of Ethanol.

The stoich of E85 is 9.87/1. Which is a lot different than the 14.7/1 of gasoline.

Otherwise, you are a blithering fool. Lambda is Lambda, no matter what the mixture of gasoline and ethanol. Lambda is also what your OXYGEN sensors read, no matter the scale they are calibrated to translate A:F into.
