ehh....all i know is that you can run leaner w/ e85 (i believe it ends up being 100+ octane), and you don't get as good of mpg... Local guy has his DSM running on e85...
a lot of people do it because of the fact that when Ethanol fuels came out, they were a lot cheaper than regular fuel. not everyone gives a shit about conserving...You don't run E-85 and Hybrid Vehicles to save money, you do it to conserve
that would be me (check out the engine rebuild link in my sig)Somones working on 1 right now, just drawing a blank on the name. Look for a thread with "cornfed" in the title.
I don't know how much horespower you planning to make, but i have a tuner here that tunes e-85. He told me that the 450cc injectors was only good for 201 whp. That is alot of fuel for just using e-85. I'm not sure how much the 310cc are good for on your build, I'm pretty sure you know what you are doing. I was going to go that route too but the more I think about it, it is probably not worth it. And yes, you are right about using e-85 on a 13:1 compression. E-85 is everywhere in Minnesota. Good luck on the build though.that would be me (check out the engine rebuild link in my sig)
i never got around to doing it though, because while i got the bottom end of my motor build (PDN pistons/LS rods/A6 block) i ran out of time to get my head built (y8 with crower 3) which would put me at almost 13:1 compression. The reason i was going to run e85 was to be able to daily drive that car. sure i wouldnt get as great fuel mileage and shit, but whatever. Being able to daily drive 13:1 without pulling a bunch of timing or being dead on with the tune is worth it IMO.
When i get that head built, it will go on, as will some 310cc injectors (whatdyaknow, abotu 33% larger than the 240cc ones on there now, so i should be good to with my current tune on e85, since you need 33% more fuel to make the same power as regular unleaded..)
so yea, built head and 310cc injectors, and i was gonna run it with that. maybe an upgraded fuel pump but tahts it.
as of 1988 every car sold in the us had to be prepared for 10% ethanol. i choose to believe that any parts that could be affected by that 10% would be upgraded to ethanol safematerials, so that 85% shoudl be no problem. maybe im wrong, only time will tell..
