That is the whole point of E85, you can run a huge amount of boost. Its like running C16 and expecting to get more horsepower out of it without raising the boost.
What does it take to go E85? Advantages/Disadvantages?
- Thread starter Turbo Habanero
- Start date

Ya. Water meth you can do the same.
But the boost it what gave the gains. Not just simply changing fuels. And a lot of things need to be changed along with tuning to run e85.

IDk, its a hit or a miss. Roomate is running on e85 in his talon for 8 months now, the ONLY thing he did was shave the % of fuel in his SAFC, that and go from 12psi on a 20g Knocking, to a hx35 at 36psi, no knock. (already had big injectors)
Me on the other hand, just to be safe ran the "correct" stuff that everyone recommends:
Pro-efi
dual 044 pumps
-6an feed, -8an suction
PTFE lines on everything
Flex fuel sensor.
Viton O-rings on 1200cc injectors
crush washers to replace o rings.

Of course the higher boost made the difference, that's the whole point.
As I stated in my original post, we're seeing 15-30rwhp gains when compared apples to apples at the same boost.
It's like comparing pump gas to race gas; the gains are due more to the ability to be more aggressive, not just a straight fuel swap.
On MR2's we're not changing anything but the pump and injectors to ensure we have enough capacity in the system.
The factory feed line has some sort of coating on it, so I haven't seen any issues when running that. I ran a -6 PTFE feed, but I'm using the stock return line.
This is all broken-record type information, there are plenty of good E85 articles and reads out there, just do some googling.

e85 will ruin rubber and plastic components. that said, there's a local shop tuning evo's and dsm's on it with GREAT results.
the shop owners evo puts down over 800whp on a mustang dyno, and runs mid 8's at around 165.

Running E85 here..
6262 1JZ, BC Cams, PTE 880s, two walbro 255s, -8 feed, -6 return, Haltech...
Really depends on what you are trying to do with the car, can be the best and worst thing for you.

I know, the dreaded question that no one actually cares about (but deep down everyone does. Atleast a little, right?)
What is the gas mileage difference between regular gas and E-85?
What is the gas mileage difference between regular gas and E-85?
I see E85 as affordable race fuel. I don't even factor in mileage, unless the Supra is on an hours long enduro. Van
If you freakin' google it, you'll find independent tests on which is cheaper. I've read that although e85 costs less per gallon, it costs more per mile. Not the point of the thread anyways, we want race fuel for daily driving

I forgot about this thread.
mecevans: the gain from E85 is because of the higher octane number and the 30% higher fuel consumption is
because E85 contains 30% less energy.
Typhoon seems to know it all
Good to see that Nick M corrected him.
The future for E85 is not looking so bright. Perhaps the E100 will take over if it's not to late.
There are too many problems with production cars.
Then we have Zach who says that there are no power loss yet the energy density needs to be calculated for.
Zach: There is a power loss and you are saying it too. If 1 kg of gasoline gives you a certain amount of power,
then you need to put in about 1,33 kg E85 get to the same power, so it's a power loss.
And yes, once you start to change the ign. timing to utilizes the higher octane number you will see gains from that.
Crypton2006: It's correct that ethanol is being added to most gasoline based fuel, but that is up to 5% ethanol.
5% vs. 85% is a big difference.
We now have a fuel called E10, so 10% ethanol, but far from every gasoline driven car can use it.
The manufacturers have lists on which cars that can use it.
Going from 5% to 85% will make a huge difference in how aggressive the fuel is to materials in fuel components,
cyl. heads and so on.
It's recommended by the manufacturers to run the car on gasoline every now and then to protect the engine.
Adding a tiny bit of oil every now and then will also help maintaining the engine.
Backlash2032: it's already posted in the thread. Your car will consume 30% more fuel to remain at the same power.

Lower. The BTU content is lower. Which is why e85 makes less power unless you run more of it and an agressive tune. And it costs a lot more. It uses a large amount of HC's to produce it, which you pay for with your taxes. It costs more, not less. Your taxes paid the percieved difference in price.

Took a long road trip this past weekend, Averaged 17 mpg.
Not too bad IMO

You can let it sit as long as you want as long as you're prepared to overhaul everything it touches.
^^^ like what?
Stores just like anyother fuel, only oxygen ruins it quicker over time than regular gas.
Sitting over a winter shouldn't screw anything up...

There are those who think they know it all because they can use a search engine (like yourself and Nick M) and those of us who get out there and do it. The rise of the internet forum has also given rise to people such as yourself, full of half truths and misinformation, but hey, it was on a forum/ came up on Google, so it's true:nono:
Those of us who have done it know the facts, and the rest of you just sit there wanking on about how much you think you know.
As I said, I've been running E85 for near on 10 months in a daily driver. If you'd like to know facts, talk to people who've done it.
I could also tell you how to get within 5% of the same fuel economy on E85 as regular fuels, and have much more power, but you're both too ignorant to listen, so I won't bother.
How long have you been running an engine on E85, and what makes you qualified to comment? Thought so.....
