i thought that e85 was bad for rubber fuel lines, and you need synthetic oil, also you need a sensor to read the fuel mixture so the engine can adjust the ratios and timing.

while it has alot more detonation resistance, e85 contains less energy than gas, and you get about 25% fewer mpg, and e85 is not 25% cheaper than gas, so there is no savings to be reaped from it.

 

That is what I was affraid of. I remember reading an article about it from before and it mentioned how corrosive it is. It also stated not to use rubber or plastic fuel lines.

 

Some states already use 15% ethanol, its fine for any new car. Its corrosive to ____ty rubber made 15 years ago. And yes obviously if your running 100% ethanol you need bigger injectors etc and a tune. And there is a benefit, you get a lot more power and its cheaper than race gas. There was an article in super street i think where they tuned an evo x on e85 and got 70whp increase on the e85 alone.

 

Brendon PSi racing, cant remember where i bought them

 

corrosive to old line from 1987 and older cars

 

Oh yea!!! Its like a new car ultra responsive and much more power

 

I looked and only found a few gas stations around where I live that have this. When more gas stations come on board I will.

 

SOoooo a bit of an adventure.... I was bored last night (like i often am) and decided to play with e85 on my n/a tc - just to let everyone know - i have a fic and 550cc injectors - it will be boosted again soon It has basic i/h/e along with a few oher things ;) Pnp head and balance shafts removed I already had the tank aout 40% full so i filled it with about 60% e85 - before starting i began my mapping I started adding around 20% fuel at idle and under load adding arond 6-10% during cruising load up to around 18% at full load (wot) I than tweaked the map a bit and gah im really impressed - i didnt think id see any gain from using e85 on my n/a car ut ive seen a nice pickup in throttle response - it drives soooo much smoother than it ever has - and the mid range torque (what i always felt our cars lacked) seems to have noticebly improved on the butt dyno Id like to get it on a dyno to test - i think id maybe see 2-5whp gain and prob 4-7wtq but just the way it feels driving it makes it worth it - i cant wait to see the real advantages once im boosted again in another month SO now it looks like ill def be going with bigger injectors (1000cC) and a 255lph fuel pump hehe

As for the people talking about corrosion - it will only damage old ruber lines - any car newer than about 98-00 is usually safe - the biggest problems are non f/i cars - carbs hate the stuff.

Also do to higher octane if you run 100% e85 alot of the guys say you can get away with runing a lambda of around 1.1 while cruising throttle - so fuel mileage actually isnt THAT much worse.

As for 02 sensors - they dont care about "AFR" all they care about is lambda or difference from stoich - afr is calulated based on a known stoich point for whatever fuel youre running than multiplying by lambda. So the stock 02 sensor will auto calibrate to run the car stoich regardless of fuel. The problem comes in that if the fuel trims get to high to create stoich thats where problems arise - thats why some kind of fuel management must be used

 

oh so your the guy he was tuning. i spoke to him and he was telling me he was tuning a TC with a standalone.. cool where did you dyno at? Lujan?

 

hey where did you get tha tube mani from? and how much? do you have a picture of it out of the car? i was getting a vulcan turbo manifold but i havent heard from the guy at vulcan turbo and left him alot of messages and called him 1000 times lol he pretty much took my money

 

I am totally for e85... I have seen cases where the fuel pump o-ring failed. I believe this was due to the alcohol dry rotting the rubber. No all the lines will have to be replaced. And the damage will not be immediate but over time it will dry out many of the stock fuel seals.

As for power output, e85 has less chemical potental energy just like race fuels (between 20-30% depending on engine dynamics). At any rate, because has less potential energy it is harder to ignite because it requires more energy to start the ignition process. This is good and bad. If you run this in your car with stock injectors on a stock map you will become the proud owner of a 100whp tc. But if you make the right adjustments, you are able to run ridiculous amounts of timing advance which is what really makes the power.

The entire purpose of timing and exotic fuels on any type of performance motor is to get the air fuel mixture to combust and completely burn by the time the piston reaches the bottom of its stroke. Any further burning is wasted and this is what drives up egt's when timing is retarded to much.

More and more people will start using e85 and realize its proper and full potential over time. And we will start seeing some really interesting hp numbers from the users... The rest of us that don't have reasonable access to the stuff will just have to play the sidelines until then.

 

Yup

 

Sorry to hear that brother damn thief. Juan did for me cost me about 1200 total.

 

Juan? From? Yuh I'm still dealing with the bank about my money

 

I switched over to E85 in my N/A TC about two weeks ago. I used injectors from the trd supercharger kit and a 255 walbro high pressure pump. I also changed out the plugs for one heat ranger hotter. I was surprised to see that the car only needed minor adjustments to correct the AFRs. I made these adjustments on a mustang dyno using a camcon fuel controller. I picked up and average of 5 whp across the board. The car does run much smoother but does start a little harder when its below 15 degrees F.

Haha where does it get below 15 very often???? lol well i guess the northeast lol Im in oklahoma - itll get down to like 22-25 like MAYBE 2 days out of the year So i see you have proof of what i found while tuning it on the road - obviousely though people need to understand u cant just dump e85 in the car and expect this. It must be tuned and bigger injectors are a must

 

I also thought about the 1 heat range hotter plugs - copper is cheap so i might go try them out

 

can u run e85 on stock 420 injection with if its tuned for it with an N/A setup..?
