How high boost on pump gas?

[OmniLuvr]

its all in the tune, from my experience, it doesnt "need" that much percent at cruise, idle can be a little strange sometimes, but wot is where it really needs the extra fuel. you can also crank the timing to gain back the power you "lose" from running it, can take some time to get it right, or get lucky! so mileage can vary depending on how and where you drive, around town depending on traffic can ruin your mileage. if it takes 20 min to get to work, but 10 of that is "sitting" in traffic, idling will ruin you, if you like fast food, the drive thru is the worst for gas mileage... i always shut my vehicle down while waiting...

in the 1 1/2 years ive ran it in the charger ive had no "goop" or any sort of build up. now i did "use" the vehicle and never really let it "sit" for more than a couple days. i had no issues in fuel filters, pumps or fuel lines. but im wondering if the "black goo" you are refering to is from fuel line breaking down in the fuel system and depositing itself inside the intake track? but ive had the strange black goo oiley build up in intake ports without e85? PLUS our current gas is at LEAST 10% ethanol already, sometimes 12 to 15%...

and i wasnt trying to "attack" you, just wondering what "your" personal experience was with it?

also, not all e85 needs to be made out of "food", they have yeast now that can break down woods and grasses, plus it can be made of of old, "discarded" food, as long as there is sugar in it and its not "rotted", apple cores?

ive even made some out of "old skunky beer"...

also my charger when still running log setup and stock cat, the emissions were "almost" half of avg for my "vehicle", stock cal, slightly adjusted fuel pressure...

My personal experience revolves more around the use of E85 in racecars (checkout the discussions on yellowbullet.com) and you'll see what I'm referring to when I'm talking about "black goo",etc.

I also agree that there are WAY more efficient means to produce the "E" in E85, switchgrass for example, will yield many more than corn, but Congress (by way of crony capitalism, something I despise because it undermines the free market) mandated that a percentage of corn be turned into fuel for E85, so while there are better ways, those were legislated out of the running, and I have a real hard time with that!

It's a good illustration of how those in politics don't really care about actually being "green", as much as "looking green", if they were genuine, they'd tell corn to take a hike, simply on an efficiency basis.

But I digress. Because the OP is looking to get started, I think the added complication of learning to tune E85 and the changes that should be done to run it on a regular basis, out weighs the very real benefits you've mentioned, it definitely has higher HP potential. That's why I referred to it as "poor man's race gas".

Hopefully the OP doesn't mind our diversion, sorry if I /we were as distraction.

I used E85 for a while, even have a post on how to do the tune.

Yes, mileage does suffer, but the power gain is well worth it.

[Ondonti]

Pump gas setups will always want a larger turbo to make big power, its just a matter of weather you can live with the powerband moving to the right. Most people can't.

Choosing a power level, boost pressure, octane, turbo, depth of engine modification blah blah is a very dynamic decision. The only way to make a sensible decision is to come up with a goal that involves performance and not just a goal of what you want in your combination. Do you want a successful marriage or do you want a partner who has 1 or 2 desired attributes?

[RoadWarrior222]

You can have your cake and eat it if you wanna do some engine work, as in, thoroughly radius and de-edge the combustion chamber and pistons, get rid of hot spots ... well that gets you a bit of cake back. Then you've got a be a bit anal in plug selection and tuning, and while richer mix might seem like it's the thing initially, it will bite you in the arse with carbon, which will tend to make glowing coals in there after a few thousand miles. Then you can also go anal with improving coolant flow, insulating ---- to keep/get heat away from the head, add oil cooling, get the cam timing "just so". Anyway, it all works as a system and there isn't a magic bolt on.

so do you actually have personal experience using it or just on the internet? i have personally used it in 4 of my cars and converted 3 other friends cars. not trying to be a dick, but that was my original question? and im just trying to defend the fact that e85 is pump gas.

so i visited the site, i thought that yellowbullet.com would be referring to the "yellow" in corn to make e85, but that didnt seam to be the case, the 8 threads i read through quickly in the fuel and turbo section that said e85 had no such indication of black goop? one guy said he had been using it for over 4 years with no problems? others have said they have been using it in motors up to about 15.1:1 fcr (final compression ratio). one guy said something about 12:1 compression and 40psi of boost in a 4cyl, another 11.5:1 and 25 psi in a chevy ls motor?

i still believe e85 is a very viable "pump" gas if the fuel is readily available? politics aside, besides the small amount of fuel mileage you lose when tuned right and the shelf life, what are the drawbacks, how long does it take for this goop to build up? what was the state of there engine before? what was the cause of engine tear down to find the goop?

i ran a stage 2 cal with flexfuel inj and timing turned up to 16 degrees if i remember correctly, and ran that setup on e85 for 6 months, but my mpg was down to about 26 mpg with that.

what is the "max" boost you can run on "pump e85" ?

id call e85 "cheap" race fuel, not "poor" mans, should we call the leaded race gases earth destroying ozone depleteing fuels? obviously im being a little stupid, but im not about to spend $10 plus on race gas when i can make similar power on e85 that i can "pump" directly into my gas tank for .50 cheaper than 87?

Black goop might be what happens after it starts removing the hard black crap the 100% dino put on there.

I may be being a bit sensitive, but I'm not going to qualify/justify my opinions/expertise here for you. Just like anyone's opinion, folks can make their own minds up as to whether or not to give them credence, and although I don't think either of us set out to change anyone's mind on the subject of E85 "qualifying" as "pump gas", it is clear to me that we will not meet a consensus on this topic.

So in the interest of not further mucking up the OP's thread further, I'm moving on to other subjects.

Cheers!

E85 has nothing to do with the question of this thread. Might as well go into E85 threads and start posting about 92 octane pump gas blah blah blah blah.

[OmniLuvr]

so e85 isn't a pump gas? we just got 3 more stations within 20 to 5 minutes away from me, the price right now is 2.69 a gallon, ya, doesn't sound like a good pump gas to me...

[x.Gen]

give some thought to the fact E85 isn't readily available everywhere. can't even find E85 here, but race gas is within reach of almost all parts of my state. you would have a stronger argument if that weren't the case (nationwide).

[contraption22]

I can edit the thread title to "Max Boost on Premium E10" if it would put the discussion back on track. Let me know.

[wallace]

I currently run 20 lbs and 93 octane with no indication of knock. 2.2 with a GN compressor wheel and stage II turbine. The manifold is a ported 2 piece lower with a box upper.

[RoadWarrior222]

Though some premium doesn't have ethanol ....

[shackwrrr]

There is a station close to my house selling 110 CAM2 at the pump, is that pump gas? lol

[OmniLuvr]

do they let you pump it into your tank is the question...

[krut]

You can pump it yourself. It's also around $7/gal.

Nice, I went on there making sure they listed Columbus Oil in Swansea, MA. Pretty close to me, and they have VP right at the pump!

[OmniLuvr]

they wont let you "pump" race gas directly into your tank around here, has to be in a carb approved gas can, good times...

[jonnymopar]

Yeah sometimes I'm thankful to live in only the second-most-environmentally-anal state instead.
