You dont expect VW people to actually know whats going on, do you?

Id say, we cant run 100% E85 in the current state. Something is obviously happening after the E85 hits the HPFP and becoming crude oil.

Yea i think @driver311 and I both (maybe even @cld12pk2go) have been running 40-50% e85 without any of the issues @phate keeps running into.

I guess it's just the right amount to not become crude oil in the pump as you said.


And no I didn't expect them to figure anything out with anything. Anyone who explodes in there pants over upgraded to T25 or K04 is MEH!

I now have ~6 tanks of 6-6.25 gallons per fill up, which is ~E40 with no issues.

I haven't gone to 50% ethanol.

Here is a link to the cobalt forum where they are talking about solving the 100% e85 issue on their platform. Apparently they solved this cause I know of a couple that are running 100% and benefiting tremendously from it.

May have solved 100% E85 on LNF puzzle - Cobalt SS Network

I read through this thread several months ago and there is some pretty good discussion. The turbo cobalt is direct injected like us so some of the issues they were having might be similar to the issues we are having. If anything, at least it will be better info than what can be found on a vw forum... :buttkick:

If you would want to look at possible injector, there is the RS4/R8 injectors that are being used as upgrades in the vw platform. (FSI)

And man the vw guys all are lame. There all okay with cookie cutter chips, and think anybody who owns a vw is incapable of tuning their own damn car. Because of this development is left up to the companies, who in turn charge a shit ton for 'stages'

but like i said. RS4/R8 injectors are disi but flow more fuel then the fsi/tsi injectors. Tsi's get to 430 hp before fueling is maxxed.

All fine and dandy but their injectors are machined differently and use a different sealing system to the head.

Until we get bigger inj e85 on a big turbo is a waste of time . We don't have enough inj as is now we will have to ramp yo the p/w to make it richer. Unless we add port inj I don't see this being viable on bt cars.

Are you refering to 100% e85 not being viable or any mix of e85 in general not being viable on BT cars?

really its any mix, im out of injectors on pump gas and meth alone on a 3076.

I knew the injectors were different, but that would be a place to start. But i know that the vw/audi forums are useless, so that doesnt suprise me that they have been no help.

And as it stands, Im with super on this. BT guys cant use E85 as a viable option. I think E85 would be a good way to max out the stock turbo, like on srt4's or cobalt ss's or the EJ platform in subis.

Most comparable to the cobalts though as they are DI. All the others can really do anything they want because of port injection

Why not substitute the meth for a e85? Just to try it

WMI cools the incoming air charge while E85 cools the combustion chamber. It is two different causes that have similar yet slightly different effects. I don't think you can truely substitute one for the other.

However, if a BT happens to get installed on my car next weekend, I will definitely be testing out the effects of an e85 mixture stacked on top of WMI. And I may go ahead and test the effects of each on their own.

What?

I sent them an email like a year ago... Don't even remember if i got a reply. But if i did, it probably wasn't any better than no reply at all.

I was just saying to test the benefits of E85 vs Meth.

all relevant AUX fueling posts moved here to keep this thread strictly E85

Where were we?

Oh yeah! E85 FTW!

My son's birthday party is Saturday, but I'm free Sunday. Give me a call.


Tapadatass

we were at Phate removing his ITFP and inspecting things....

More info on the gunk I should have posted earlier:

The "gunk" has been a sticky tar like residue every time I have dealt with it. Every time I have dealt with it, though, has been immediately after pulling it from the car.

The stock internals from the second pump were never cleaned after I did the testing with it. When I went to put them back in last week, they had been sitting out (out of the pump body) for 6-8 weeks. The gunk had become a hard, carbon-esque material. Next time I pull the solenoid or pump and it has substantial buildup, I'll take a sample and keep it in a clean container to give everyone a better idea of what I mean.


@superskaterxes - thanks for cleaning up the thread, lol.

Have you considered contacting Blackstone to see if they can test it?

LOL, no. So I just called them and talked to Randy. He said they might be able to test it. If I can get a decent sample size and send it in, they might be able to dilute it in kerosene or something, and then run their tests.

He mentioned seals, and said it could show up as silicon in the mass spectrometry reading. From there, other tests could be run, but I'll have to talk to them once I send in a sample.

Long story short, I need to gather some of it and send it off. Once they have it, we'll talk about possible tests and possible pricing.

@Mizzle - thanks man, good idea.

Looks like someone's possibly going to find out where that new-found engine bay fuel spray is coming from.

Haha!

There is definitely an issue with the in tank pump. Over the weekend, I saw the fuel pressure drop to almost nothing while cruising at steady speed. Opening up the access hole is becoming more and more appealing.

Hate to say it but I may be going back to just 93 for a bit.....Waiting for more results as I can't afford to have anything go down atm.

Once I pull the in tank pump, I'm switching back to 93 octane for about a month. I'm headed down to the tail of the dragon labor day weekend, and there's no E85 close to where we are staying. This seems like a logical point to switch back.

The whole pump assembly is plastic, and there are a few rubber-ish parts in there as well. The fuel filter is a cloth material, so I'm interested to see where the problem lies. I'll take lots of pictures when I do it :)

God i want to cry....my car has no balls....Not that it had alot before but....with no e85 on a fairly agressive 93 tune it feels so slow....

Still rocking on with E40 here...

I really need a 3 bar MAP sensor though as I am pegging the stocker around 23 PSI...

I won't last long on 93...Im like a crackhead phoening for some rocks aka cornjuice!

same thing happens when your "dealer" runs out of meth for the winter....I'll be stocking up this fall LOL.

poor @cld12pk2go is hooked on both hahaha

I do like getting 26 or 27 mpg.....But i think after this tank im headed back...

I get more smiles per gallon with my current mix...

true....I'm bout to go top off with e85 tonight LOL....I can't take it anymore LOL

I haven't gone full throttle in weeks, now :/ Talk about withdrawal.

Months here... 2 to be exact! Stupid leaking DP! I'm fixing it (hopefully) tomorrow though!



Then... e40 here I come!

So more E40 love on the way to work today.

Everything is cool. Still pegging the stock 2.5 Bar MAP sensor around 23 PSI.

Loads in check around 2.05 as desired.

On the way home I got a heck of a surprise when I saw my boost gage shoot to 28 PSI!

Nothing like 28 PSI and 2.3 load at 2400 RPMs to get the sphincter puckering... :smileeek:

Fortunately I lifted immediately (not a bad reaction time between recognition of problem and lifting or perhaps I just got lucky) without issue and found the following when I got home:

http://i77.photobucket.com/albums/j6...aponnipple.jpg

I had lost the bottom cap on the WG nipple some how on the drive to work after the initial pull, which makes sense given how the ECU was forcing the WGDC to zero trying to decrease load in the afternoon pull.



New one is clamped on tight with a hose clamp:

I do not wish to think about how this might have gone down on 93 octane...

However, this is another interesting data point showing how strong the stock bottom end is when you aren't knocking...

Also it would appear that my new clutch is going to be able to handle what I am planning to throw at it. :drive:

Im back on the crack...LOL

so phate when u gona reach in and fondle your INFP?
