i have e85 right now, but thinking about switching to e47. what kind of #s are people seeing on e47 oppos to e85? how hard is it to mix the fuel at the pump? 3 gal premium and 1 gal e85?

 

E47 is 50/50 not 3:1. It's been proven that you can make the same power on E47 that you can E85. I think once you start reaching higher horsepower, like 450+ it's probably beneficial to use it straight. I'm not exactly sure where the turning point is tho.

I've been running E47 for a while now. I just pull up to the middle of both pumps and put equal amounts in. Simple as that.

 

Stock fueling on a fully bolted LNF runs out around 65%-70% E if running 24 psi boost. I know people that can run full E85 on a fully bolted LNF but normally the midrange torque has to suffer to get enough fueling. E47 is the bomb. 360 whp/400wtq on a fully bolted stock turbo LNF.

1:1 93 & E85. 24* advance. You'll need a clutch. lol.

 

^^ Reading your research is what made me want to run E47.

 

sounds like a good idea to me. thank you for the advise. i ordered it from vince, hopfully get it soon. fully bolted=?
like intake, turbo back exhaust, pressure pipes, fmic

 

yep.

 

Hmm so maybe ive been mixing my e47 wrong by the way your saying you mix it 1:1...I fill with 6 gallons of e85 4 gallons of 91...is this wrong

 

Are you guys DD your cars with e47?

 

Yes this is indeed incorrect for e47, unless you have a different blend other than e85 you are mixing with of course. I know in my area they switch to e70 in the late fall, winter and early spring so I have to make close to a 2:1 mix of 93:e70 at that point. Anyone who runs an eblend would be wise to invest in an ethanol tester so they know exactly what you're dealing with in order to get the correct blend you are tuned for instead of guessing and coming up with all these random mix ratios I keep seeing. Otherwise your trims will be through the roof.... or through the floor depending on what you're blending more of.

 

I wanna Run E47 soooo Badly but it sucks cause the closest station around my work is 30 mins away and I would have to get a bunch of 5 gallon drums/containers filled up at once to make it work and I dont have a way to transport it safley, How do you guys do it?

 

The closest e85 station for me is an hour away so I'm kinda in the same boat.

I actually have a 35gal container with a 15gph Fill Rite pump that I use to fill my tank. When I run low I just drive my truck to the fuel station with a few 5gal fuel containers and fill them up to top off my tank. I also don't use my balt as a daily driver so this has worked great for me for the past year and a half that I've been running an eblend.

 

im on an e47 tune from css3 and im on a 24lbs steady at 26* of timing. I dynoed a couple weeks ago and my numbers was 331/397 BUT my IAT's was 125+ and the car pulled 5* of timing out and i spun on the dyno for about 1000rpms, lol Or else my numbers woulda been in the upper 360's area But all in all, im loving the tune. As far as the mixing like stated above its a 1:1 but my tune is setup conservative as a just in case i mess the mix up (like i did last week) lol I ended up putting almost 2 gallons more of e thatn 93 whoops, lol. I daily mine as well.

^^Was there a blizzard blowing in your face and you were walking up hill with no shoes on as well? Lol

So you mad less whp due to kr, yet you still spun on the dyno? You must have some strange luck my friend. How do you know your IAT's were that high anyways?

 

are their any drawbacks on the effects e47 has on a car? I know it's more corrosive would seals for the fuel system degrade at a rapid rate because of it?

 

Where do i get an ethnol tester? Is it easy to read? I dont really understand the whole gas and ethnol stuff. Just thought it was an easy mix. Lol but i am trying to learn as i wana kno as much as possible.

 

There's a theory that it eats away the old-style injector seals, like on the '08 cars, but I've been running E85/E47 for over a year now and haven't had any problems.

IamBroke up there (Tom) tuned my car and he comes highly recommended from me.

 

I have a dashhwak in the car and was watching the iat and the kr at the same time on the screen. I spun at the beggining of the run when the boost hit full spool, but in the upper rpm's is where the timing was taken out on the run.

Gotcha.. I just wanted to bust your stones a bit. I like when folks give a million reasons as to why they didn't make a certain power level, and guess as to what they "should have" made if xxxx conditions were perfect. All that matter is what you actually made in the end..

What intercooler are you running btw?

 

E47.5 rocks in a DD, all year round...

 

in for results,in person or in the next lane when we run again lol. you pulled on me by a car with an e85 tune and i want to see if the e47 make a big difference or not.


good luck,mark!!

 

I still win!

 

I think a possible downside to E aside from possible injector seals is the DI pump getting over taxed. My hpfp is on the fritz now. Seemed to start acting up after the BNR went on. I'm wondering if the extra flow required just stressed it out on E47. I dunno but I am pretty sure Cumbow had the same thing happen but not sure if he is on E tho...

 

LOL it cool, no worries on my end. Yea ik at first it mighta seemed kinda ricey for me to say"shoulda" but ehh oh well, lol.

Im running the MPx intercooler. Ive had it on for year and a half now and havent had ANY complaints to it other than the inlet and outlet was smaller than the oe 's. Which i fixed by just using tapered couplers.

Explain plz?? lol

Oh, haha. You hinted to me once that since you have upgraded pistons you would make more power than I did on E47. That's all. I know it's all based on various factors, just having some fun with ya.

 

haha really?? i did??? Hmm drawing a blank on that one, lol. I know ive said that i was hoping to be up in the top spot for stock turbo. But dont recall saying i would be more than a BNR powered car, lol. But oh well ive slept since then so who knows, lol
