Some how this thread is starting to turn in to "I hate ethanol in my pump gas" thread and this topic has nothing to do with the (e10) fuel you use in your passenger cars - period. clearly I see the interview in a different light than some of you do, I guess I chose a bad example cuz we are getting in to government amongst others that are not related to this subject mater. The point I am trying to make is corn is not the only source and is actually one of the lowest yielding crops to use for ethanol. You people are ignoring that with what corn that is used the "by product" is still a viable feed (even enriched) for cattle so it isn't "just thrown away" as a waist material. Some how most everyone ignores this. More over there is a common mistake that people associate ethanol with methanol and there are not the same alcohol.Lets talk about e85/E100 and leave your dislike about your passenger car fuel out of this please This is in the race section for a reason and not the street area


p.s fact is the government does pay some farmers to "not" grow crops ......hmmmm

Im back on my meds and feeling much better. :o
It's a great topic but IMO the videos may have been better suited for the Lobby. :)

so political interest debates aside... I have seen a few articles on converting Holley carbs over to e85, has anyone come up with general formulas for converting the qjet to e85? I have an AF gauge in my car, so maybe something I need to experiment with next spring on a spare qjet...

I would imagine with the small bowl that's on a quadrajet it'd be a challenge. Ken Jones Performance in southern IL. did my holley and it works great. He has a web site, might want to talk to him. I know it takes a lot larger needle & seat than gas. I had my rear needle/seat leaking on my preped carb back in the spring so i just went to a local parts place and bought a new SS needle, wrong size and was running out of fuel on the back of the carb right before the traps. Had to buy one for alky cause a gas one won't flow enough. Remember it has to flow 25/30% more fuel everywhere.

My Chevelle was on e85 for 3 years. Lots of street mile and track passes. Worked great. As long as I kept a couple cans of seafoam in the tank I never had a problem. Without the seafoam, it would gum up the nitrous plate. E85 on both small and big block combo proved to make less hp and run a tick slower than gas.

My red truck is on e85 for two years now. It's injected so I see absolutely no problems. It picked up 100 hp because it's turbo.

Ethanol does not collect moisture in the oil, especially if the tune is correct. I saw no negative effects of ethanol on either vehicle except for the nitrous plate gum up. Everything else has been ****. Just keep a couple cans of seafoam in the tank .

Very helpful information in here. I also here the benefits of E85 is the you can run higher compression motors with no issue boosted or NA. what would the limits be there? As far as compression limits. I had a local engine builder tell me you'd be safe to run 13 to 1 compression on n/a build with E85

I have 14:1 in my motor and no issues at all on E85. I could use a little more static comp actually. If I would build my engine over again I would go with 15:1 static.

Staying with 13:1 will be plenty safe.

On paper you can run as high as 16:1 but the norm is around 14.5 for the most part. Naturally the higher the power level & cr you run the more critical fuel % is going to be but 13:1 is a very easy/safe cr with e75-85 for NA motors. This current build we are at 14:1-14.5 depending on what head gasket we use.

So far gains from going to e85 has been netting about 15-20ft/lbs across the board on the dyno (4000+ rpm). Even though we are using two of same model carbs they are in fact different carbs so it is hard to truly quantify the exact gains. Ideally an injected system would be the most accurate to do a back to back comparison.

I haven't read the entire article but it makes a few good points, there is however at least one flaw and that is they say you need to go two heat ranges cooler on plugs - this has not been the case with NA & ethanol but has merit with methanol. You should however use a recessed tip plug. I could see how a closed camber iron head (IE:670's) could start to be a bit picky though at the higher end of cr's

I used the same plugs I used on gas with both my engines. Even used the same carb, 406 Pontiac, 406 SBC, although the Pontiac liked more fuel. Pontiac is 12.5/1 16 headed street dominator. Seems my Pontiac always liked more fuel, even on gas.

Man you got to love the E85 So far I have heard more pros than I have heard cons with the 85 How are the high compression cars running on the street and with nitrous ?

You should see lower engine temps and your "butt-ohmeter" should also detect some added umph. And yes there are people that run NOx and maybe we can get a few to chime in on this.

Thanks WARPed as far as fuel pumps go I have a Aeromotive A1000 and have read that the E85 can eat the glue away from the magnets on the pump but have fixed it on the newer models does and one have the know the dates that aeromotive had fixed this problem?

I have sprayed ALOT of nitrous with e85 in different customers cars. It's a little tricky but not bad. On all motor and nitrous they make a touch more torque down low, but a touch up top. In every case, if we switched back to gas they went a small amount faster average et for the season.

But it's worth a little power jet for jet if you only give 3 bucks a gallon for the stuff. Just spray more nitrous!!! Hahah

BrandX,You have a PM

Did you ever run e85 on your old nitrous set up?
