E85 Who has done it?
I use it in all of my cars other than all out drag/dyno.
Example: (88mm, 408ci) we went from 803rwhp to 891rwhp with nothing else other than a complete re-tune.
Due to the swap we could run a couple psi more and still be on a safer tune than with our 98 octane (your 93) and that car gets driven around 900km (550 mile) a week
Its cheap, you get huge power gains, cooler temps plus its good for the the globe
DO oversize your injectors. I like the ID2000s. PM for a good price. If Nick is tuning it, he will love you. He and I have known each other for 6/7 years now, so feel free to use what I have learned so far to reduce your learning curve.
DO run a big feed line. I always oversize atleast one size up. Its never hurt. Its always hurt when I run into pressure drop or improper line sizing because I went too small.
DO run a BIG stainless fuel filter. 25micron or smaller. I like the Monster Mesh from Kinsler.
DO test your E85. It takes a 125$ tester to test it and an ohm meter. Ive heard of less than E70 at some pumps, but have tested personally, E70-E86 at the local pumps here in dallas all across the last 6 months. It just recently changed end of november to a winterish blend.
E85 starts out life at E100. Naturally, with no liquor license, it gets cut with crap to E98.
From there, you can purchase E98, and cut it yourself with your own 93, or 100 octane to achieve your E85, or what ever Ethanol content you wish.
E85 at the pump is cut with what ever, 87, drippings, refinery trash, what ever they pick.
Having said that, in a typical spark iginition engine, E70-E85 have virtually the same Antiknock qualities between them, with in 2%
It accepts the same timing as C16. You will usually melt parts before it knocks. Thats been my findings.
Other than that, use good Ethanol rated stuff, hard anodized aluminum, and stainless in your fuel system parts, and go to town!

I test at the pump, takes about a minute, and a few goofy looks

The Kroger in Sachse and the Kroger on frankford/midway both are currently E73-E76 as of a week or so ago
The pumps in Orlando for War of Imports were true E85
Looks like this. It looks like this one.
I think it was cheap. Like under $50 bucks.
E85 is working great for me so far. It takes 30-40% more fuel which is tough with an electric pump. i ran out of fuel at 850ish rwhp with a 4303 magnafuel.
i just checked my BS3 log, with 160lb injectors i am at 76% duty on E85 with a base fuel pressure of 50lbs. that at 14psi of so. 800rwhp.
not knowing much about your car make sure your fuel system is alky compatable. any filter with paper in it will gum up. it happend to me, mesh screen filters are the ones that work best. Easiest way to tune is assuming your gas tune is good. add 30% to you VE. thats what i did in Big stuff 3. then tune it to 11.0 a/f, i know my car seemed to make more power in the 10s a/f. some say its to rich. its up to you, a dyno will tell you where it is best.

That said I'm sure he would love those injectors but my bank account wouldn't. I already have the impedence converter in place so I will be trying to stay with a low impedence injector. Thank you for all of the other tips. I have been talking to Lonnie at Lonnie Performance and we have some plans for the fuel system. I will keep all of your tips in mind as we upgrade. Your experience is much appreciated. E85 is working great for me so far. It takes 30-40% more fuel which is tough with an electric pump. i ran out of fuel at 850ish rwhp with a 4303 magnafuel.

the 4303 is the largest magnafuel for street use. i bought another 4301 to run in parrallel but decided not to use it. i figured you need 2.8-3.0 gal/min for 1100-1200rwhp on E85 through a th400. the 4303 pumps out 2.5 gals/min. i added the alky kit which is 0.5 gals per min. to get me to 3g/min. my buddy ran a big magnafuel pump that is 3.1 gal/min and had good fuel pressure. You could also run a boost a pump. i might do that to mine in the future. a guy did on yellow bullet and it increase about 200hp worth of fuel.
hope this helps

It looks like I still have a bit of headroom then as I kind of go off of the same calculation that you use with a single 4303 at it's nominal flow rate would be around 1000 rwhp with a manual trans. The bigger magnafuel pumps seem to put quite a bit more heat into the fuel and they don't recommend them for much street use. I certainly wouldn't be opposed to using a KB Boost a pump on this thing if I need to just because it's one device I haven't seen fail yet so I consider it to be pretty damn reliable unit and it's not like it would be spiking the voltage all the time so I wouldn't think of much additional wear to the pump at all.Thanks that definitely helped!
We use two bosch 044s, and they are right at the limit at 1100 rwhp. Enough to push a 3300 pound car to 160 in 1500 DA. I added some larger wiring, changed up the feed line a little bit in hopes to extend the pumps further. If that doesnt work, I will add a boost-a-pump. Its still a street car, we dont want to run a Dial-a-flow and a weldon, so twin intank pumps is where we want.
I forgot about the fuel filter- Stainless mesh is the only way. Paper will gum up for sure.

I saw things on the dyno that would have caused any gas engine to disentagrate instantly.with e85, the engine held up fine.
