E85 VS 93 with octane booster like Torco

[Silver50Pony]

What kind of pros and cons would it be running 1 over the other especially for long term effects like fuel system damage? I know Torco does add a lot of timing due to the added octane it has proven to provide , but will it cause more problems in the long run com pared to E85? Especially if it's not someone's daily driver which I'm sure E85 can cause moisture and gumming of internals.

E-85 is where it's at if you have that as an option. Much cheaper and can support lots and lots of power.

You think our cars can handle e85 long term ?

Absolutely, no reason why they can't.

E85 has it's drawbacks. Any water at any stage becomes a much bigger problem.

If you are boosted then you will love E85. NA, personally i didn't. I tried E85 with the flex tune but it gave me the same 30 degree spark advance as the 93 octane. E85 specific tune can push your spark timing to 32 degrees. I honestly get better performance and driving experience with the 93 octane. My dyno also showed power and torque loss with the E85. It may be due to the quality and the real alcohol level, but that was from shell gas station. 93 octane car put down 404 whp 375 lbft, and on E85 395 whp 367 lbft. I know energy density of gasoline is alot higher than E85, so just to match the energy you have to consume 20 30 percent more E85. I will never run E85 NA with this car! So race fuel or 93 octane plus torco or lucas may be a good choice.

i eaw 31 degrees of timing with 93 and torco.

Ethanol is cheaper. Can run a lot of spark and boost. But keep in mind, ethanol doesn't have any lubricating factors to it. Some areas it's not available or very inconsistent. Even if you could find good E85 Everytime. I'd still run a tank of premium every so often. Plus E85 doesn't like be stored for long periods of time.

We don't have much E85 in my area and don't drive my car very often, so I went with the torco tune. Still gotta do some data logging though.

Vp fuels sells x-85 which is a true 85% ethanol. Not to mention c-85 which is good for a 5% bump in hp over x-85. These 2 will be my track fuels...and pump e-85 gas will be my street fuel. I go in for my flex fuel dyno tune june 5th...

What's the worst case scenario running octane boost like torco to get similar octane that E85 provides and just have Lund bump up some timing with that... maybe some fouled spark plugs? I'm sure if I don't over mix torco the plugs will remain ok
I'm NA no power adders

You can ask Lund to give you 32 degrees of timing with high octane fuel. That way you can run 100+ octane and gain from it if you would like. Running regular flex tune with a good 93 octane plus octane booster will also get you good spark timing.

Plugs will be fine and might have light orange coating from the MMT but still really no drawbacks unless you still have your cats. It's supposedly bad for cats and O2 sensors. I ran E85 for roughly 10k miles but prefer to run Octanium and 93. Timing ramps in a little faster on my flexfuel tune over the E85 and I don't have to drive out of my way. It is a little more expensive though.

I prefer e85 for its cooling properties, especially now that I'm boosted.

I have run and dynoed both setups. I run torco in my 93 in the colder months for better starting and to keep from any moisture issues or build up. I run e85 in the warmer months because the car is effected less by the heat and it just plain makes more power. I have run on two different dyno's by two different top level tuners and in both cases the e85 made 10+whp and 15+wtq over 93 with torco. The torco is great to ensure full timing advance for what is commanded but most tuners are not adding that much timing on a 93 tune unless you specifically have them tune with your exact torco mix. Remember everyone that 30* of timing on 93 does not make the same power as 30* on good e85. Advantages of e85 go beyond just the timing. That being said gas mileage sucks (usually 12-16mpg for me), its not always around and its good to run a tank or two of 93 through the system every now and then.

Will octanium fry the cats and o2 sensors ? Looks like good stuff
