Damn. I really want to see a permanent hardware solution come about for the people who would like to daily on E. Additive solutions seem to be working great but I feel like that's more added maintenance which I (and probably a good amount of others) would rather not deal with.

I'm going to look over the patent info for our pump and see if anything sticks out to me.

Edit: Wrong thread.

Ok so I read through the patent for our fuel pump, found here: Patent US20030017069 - High pressure fuel pump for internal combustion engine - Google Patents



And I've come up with the following for solutions (or at least help) with high Ethanol concentrations:

1. Coat the retaining nut and spill valve threading in a resin coating which would insulate the parts and keep heat from spreading.

2. Replacing seals with O, X, or K rings of superior sealing ability, or possibly adding additional seals.

3. Increasing the seal between the cylinder and the pump body. This could be done in couple of ways.
.......A. Increase the torque on the retaining nut to press the cylinder harder against the pump body.
.......B. Surface harden the cylinder so it can press into pump body to seal better. Possibly in combination with A.
.......C. Put some sort of deformable material such as part 70 between the cylinder and pump body to create a seal. Possibly in combination with A and ...........B.

4. Improving part 30, the seal between the cylinder and retaining nut could be improved.

Not all of these may work but that's what I came up with after going over the patent. If our pump isn't that different from the LNF pump then I think it's very possible to run full E85. The patent goes over the seals pretty extensively so I would definitely recommend taking a read of it.

Here is a picture to get a good idea of what I mean by sealing the cylinder to the pump body.

As well as a picture of seal 30 and 70.

Counter arguments for each; not trying to shit on your rainbow but I've thought about the pump design at great length as well.

The internals themselves have direct contact with super hot engine oil as well as a set of lobes on the camshaft; heat conduction will happen regardless.

Our pumps actually have *two* seals/oil control surfaces already. One is an X shaped buna ruing on the narrow end of the retaining nut, and the other is a little plastic scraper backed by a regular shaped o-ring on the fat end. I had my gunsmith drill this part out and plug it with a piece of PTFE that was also center drilled, but the tolerances are so fucking tight that when tightening the last couple of threads on the nut, the drilled hole in the PTFE was off just enough to seize the internals and prevent actuation, so that idea was scrapped. Yes, he used a drill press and lined it all up while installed in the retaining nut.

If you're going to increase the seal anywhere, it should be on the narrow end of the retaining nut. Closing off the internals from allowing fuel to flow around/through them will result in metal on metal contact and a hardware failure; I'm pretty (~99%) sure that the cause of the issue is oil entering the pump.

See 3.

Our best bet right now (both cost and effort wise) is oil + additive, which so far has been promising to a remarkable degree.

At what point (*) is this happening though? I know oil coolers assist in this but too cool of oil isn't good either. I'm sure someone has thought of this, just didn't see it.

It probably happens at a lower temperature with a hot pump due to the innate 40-60 psi the pump will see at resting preventing the e from boiling and removing heat.

Just found these fuel pump internals that I don't think have ever been tried on a MS

Integrated Engineering

Seems to come with a retaining nut?

Wonder if they can service a mzr pump. They appear to be like APR, requiring you to send in the pump to be rebuilt. Its nice that I have a spare pump here, just need the money to send it in. I love new testing opportunities.

They offer a self install kit

Pump internal kit only- This is the entry-level HPFP kit for builders who prefer to assemble their HPFP themselves. Each kit includes all necessary components and a detailed install sheet to get the job done.

You're right, my mistake. I skimmed through the article failing to look at the top.
$500... Fuck.

Yeah the price is the first catch, might be worth calling them? See if they know anything about e85 compatibility etc

I would but in Australia :-)

I'm selling my internals. Going to be on my stock fp internals for a while. My stock clutch is gone so I can't really go fast anyway. My next internal set will be these. I have to try them out.

Sent From a Galaxy, Far Far Away...

Upgrade the flywheel while you're at it.

Which option are you going with? Have you contacted them yet about ethanol compatibility?

I'm asking Santa for a new clutch. I'm debating on a few.

I'll call them after I lean all I can about them. If they don't work out I'll just pick up another set of at's or CS internals.

In the meantime... I'll be running the stock fuel pump on full E. I won't be putting a lot of load on the engine, fuel pressure "should" be OK.

Sent From a Galaxy, Far Far Away...

Zero your VVT, drop the boost. You'll be fine.

This sucks not only am I a slow fuck, my RV is failing too. 10 months of straight E is taking its toll on my fuel system. I'm going to have to run a few tanks on petrol to clean it out.

Normally after shutdown, my fuel pressure would climb to 1875psi then the RV would open. Now after shut down it immediately starts to loose pressure without climbing. Joy

Sent From a Galaxy, Far Far Away...

Is the engine hot? If it's not hot, it may not build pressure because there's no heat in the injectors/rail to cause it to increase in pressure.

I ran it for a good 20 mins... I take it for a longer drive tomorrow to Make sure

Sent From a Galaxy, Far Far Away...

Did you dial your hpfp pressure settings in to keep em below the RV crack limit? If you just leave them all at 1700+ psi or whatever your RV will be constantly opening/closing throughout any WOT pull. Mine is set to 1700 or so for only a short window then tapers down at redline to prevent pressure from running away. Usually only one blip above 1800 or so for a 4th gear pull. Rest is mid-high 1700's.... Good pressure AND happy RV!

Well, I decided to get back to testing e85 death solutions. Last week I ordered Integrated Engineering's internal kit and it finally came it. This kit is beautiful. Check it out!http://tapatalk.imageshack.com/v2/15...7e8339c17e.jpg

These internals come pre broken in, literally install and WOT (according to IE). Everything was individually wrapped in sealed plastic soaking in assembly lube. I can't wait to get them installed.

I have searched high and low on the audi/vw forums looking for a failure. There was none. I don't know of any Mazdaspeeds currently or ever using this Fuel Pump internal. So should be interesting.

Wow, these things are quiet. Sounds like I have stock internals. Throttle tip in sound is not Audible. I wish I had a way to monitor fuel pressure.

Assembly was simple, much like the autotechs except for getting the piston through the seal. The seal was tighter the a 16 year old virgin.

While it hasn't been a problem for us, cam follower fail has been a serious issue for the VW/Audi 2.0TFSI. I'm not saying it will be for you, but please take a look at your bucket now and watch for signs of wear. I know we don't have the oiling holes, but I also don't know if this is going to increase friction / resistance to the point it damages our cam follower. Just an FYI.

http://i.imgur.com/47WLNewl.jpg

These internals were said to reduce cam follower wear on the 2.0t. I am sure I'll be okay. Besides, ran my pump for 400 miles with sticky internals. My cam follower still looks fine. I'll keep an eye on it, it's good to be cautious.


Sent from my iPhone 6

I came from the 2.0T platform and the cam follower fail is very real in their world. Some vendors/manufacturers have gone so far as to offer reinforced cam followers. Replacing the camshaft in an Audi is EXPENSIVE and thats what this leads to. Interesting enough, the Audi community absolutely swears by Welcome | HPFPUpgrade.com and we dont hear a mention of them in ours.

Curious to see your experience with these loogie.

Edit: Just opened hpfpupgrade.com and they even have injector seals.

Ohhhhh we hear mention of John/PTP/HPFPUpgrade/DFDD and whatever other name he's selling under these days....

I believe he was referring to @Enki; 's response of someone needs to resolve the fuel level sender and its compatibility with corn.

Yes, but see below.


In the past, gearheads were nominated by other gear heads. I don't see that as the only possible way, because the gearheads cannot frequent every thread on the forum to keep up with certain people. My suggestion is to start a nomination thread, because randomly suggesting it in a post will get lost quickly.

Tag @Raider; to let him know about the potentials and the ensuing discussion, because he is likely the only one who can actually make changes to the group in the absence of Haltech. Tag the other gearheads, because I think they should weigh in. Cite work (link threads) accomplished and state why you think they are deserving of the gearhead title. There is a thread in a separate part of the forum that has these outlines for gearheads:

Pshhh I already solved that one.

Sell PU
Buy 'Won.

Over 6k miles full E85 without a single fuel level issue.

I R GearHead now?

Your doing it wrong. It takes months for them to forclose then once they do you can just break in and continue living in the house for months or even years while they try to sell it.

Also you can live in a car you can't drive a house.

There are two ways to gain admission to the club

1) blow Haltec..fairly easy BTW.
2) blow all the existing GHs, more difficult but you gain greater respect.

dealers choice.

but seriously at one time it required a nomination from a GH then we all voted then it went to Haltec for approval...I am fairly sure that is no longer the case. We all used to be mods as well but there was a bad apple in there somewhere that got that taken away. So basically I am out of the loop and don't know shit...lol

Can all the blowies be rendered at once, for time saving/efficiency?

What was this thread about again...?

It used to be about modifying our fuel system, now it's more about me bitching about everything.


Sent from my iPhone 6

So.....MSF?

Anyway back to my next project that I will be working on this year.

I have always had problems with fuel and E85. I like to push my K04 at 20 psi all the way to redline. The problem with this is I always seem to run out of fuel at about 5300 RPMs. Some of you have told me it's spark blowout, others have said that the problem is the HPFP. I personally think that the injectors are taxing out.
So, I decided to try to tackle a project that will benefit everyone. I am going to take my injectors and open them up. @Enki; suggests that I shoot for a 30% increase for people running E85. Though that would be nice, I am going to take things slow and not push it.
I opened up a wanted to buy add in the classified for some broken/used injectors and not one person has tried to help out. Kind of the same boat with the last project I did with the HPFP. So naturally I had to buy more expensive injectors that actually work so I can break them. So whatever.

Also, I sourced a laser welding shop to seal the injectors back up after mods are complete (if they need be opened up at all)

Please discuss, call me crazy, give idea's, Draw me a picture, I don't care.



Sent from my iPhone 6

OK- You're crazy :biggthumpup:

but, you know, in a good way


IIRC, wasn't it PTPJohn (spits...) that farted around with just enlarging the injector opening? Also, IIRC, it was determined that changes, as he was making them, only resulted in bad things happening to the spray pattern and essentially a total loss of any decent atomization.

I'll search around some if I get time today and see if I can find those old threads unless somebody else beats me to it or more relevant info comes up instead

Gearheads nominate gearheads in their section. no mods, no haltech, just GH.

OK!



http://www.mazdaspeedforums.org/foru...1&d=1429272447

IIRC both John and SSInstaller enlarged the injector orifices and fucked up the pattern to the point gains were meaningless.

I wish loogy luck but the injectors are much closer to rocket science than the relatively simplistic CDFP.

IMO both the needle and orifice need to be extremely precisely matched to make a good injector. I think in the two above examples they may have achieved marginal IDC overhead but drivability went into the dumper, Idle, CL and PT operation suffered. I would not be surprised if ran very long the wall washing would have caused motor damage.

going down the injector road will be a journey for sure.

ssinstallers worked fine but he stated after the fact that it wasn't worth the headache or expense for the marginal increase in headroom.

Who knows what to believe about johns adventure.

littleloogy; does this mean that we won't know results on the IE fuel internals for a while?

Got my car back last night, roof paint is flawless again. I am still on petrol. I am going to open my AP tonight and get a base E85 map started for my car. I'll drain my tank tonight and should be on E for my NATOR drive tomorrow. We will see how it goes.

ALSO, SP63 has posted about messing around with porting the injectors. They've got some photo stuff on their instagram but as per the norm they ain't said nuthin about it.

AND, I think Total MPS managed to make an adapter to use EcoBoost injectors on our head. But don't quote me on it.
