E85 conversion?

[NoRemorse]

So I was thinking.... with the LC-1 and HPT available....I could reconfigure my LC-1 to change the cruise AFR for E85, and use HPT to add the fuel needed for more alcohol in the fuel... And being in Michigan, E85 pumps are VERY common (2 with in 1 miles of me right now)

I could swap out my fuel lines to some that are a little more corrosive proof and run E85, which is cheaper and would allow for a lot more timing/compression/boost because it is the equivalent to like 102 octane...

any ideas guys? I am just toying around with this right now

Hell, corrosion wouldn't really be a problem from what I have been reading. Cars of recent years have been designed to at least accommodate 10% ethanol, and should be able to handle a lot more.

From what I understand you have to use more fuel to go the same distance as you would on normal gas.... but from what I can tell, if you do the conversion properly, that is the only downside

Indy (the racing league) is convertering their vehicles to run on like 93% ethanol (they add just enough gas to make it fuel) and one of the test drivers said it smelt like a deep fryer in the pits..hahaha

so the E85 has more alky which increases octain rating which allows you to run more boost, timin ect ect. so what are you waiting on???????????

MPG could go down because there is about 15% less energy in the ethanol, but if you can increase timing and compression in the engine, you can get MORE usable energy out of it, and about the same mpg.

But it is cheaper anyways, money does not go to OPEC, but the reason i like it... 102 octane!!! bring on the boost!!

I seriously think I am going to do this in about 2 months. I will let you all know how it goes. E85 is sooo available to me, it's not even funny.Worst case, what could I ruin? my fuel system? lol..... I'd just try to warentee it if it does happen...lol

so in a nutshell fuel consumption is the only downside which dosent matter at the track right? git er dun brian. let us know how she goes

E85 is half the price of race fuel.

Well fuel consumption is sort of a downside...like NR said you can get the same mpg if you tune your car for it (hell Indy cars are getting a 20% increase in fuel mileage so they had to make the tanks smaller so they have to pit just as many times...)

Exactly, if I do my build around 85% ethenol, I can get the same millage.

Right.

Commercial E85 vehicles are seeing a 20 to 30% mileage drop (real world numbers, not sticker numbers..and this is on average, some are getting the same), but at the same time are the vehicles tuned to run specifically on it? No, as they have to be ready for normal gas to be pumped in..

If you tune for specifically E85 you can achieve the same, if not better mileage with more power on tap...but if you have to put normal gas in, you better have another tune ready to throw on (all that extra timing likely wouldn't do you so good...haha)

they just need to come up with a set of tires that dont wear out and they would be all good. who needs to pit anyway


N/R you going to try this and get your damn car on a dyno?
