back on topic....

Dano 08-01-2011 04:45 PM

well VW/Audi is where our best CDFP internals come from so there's that.

KMD and Autotech IIRC.

bewsted 08-01-2011 04:47 PM

And now i begin recon.

djuosnteisn 08-01-2011 04:52 PM

Cp-e uses APR i believe.

They hpfp's work well, cause the pistons are also herrarflushy.

Dano 08-01-2011 04:56 PM

I stand corrected :)

bewsted 08-01-2011 05:12 PM

Yea i was under the impression they were ARP internals as well.

Oh well either way we are all accomplishing the same damn thing.

UPS site says my new fuel pump assembly was delivered today :)

I can't wait to see it, especially f it's a drawing of Dustin's cock.

By the way, do we know what company actually makes our injectors? We might be able to contact them directly for options on upgraded injectors.

isnt the problem our HPFP getting gunked up?

bewsted 08-01-2011 05:39 PM

No problem is @phate fuel pump gunking up. I haven't seen anything like what he has had....Guess the 50% 93 dilutes it enough to stop the corrosive act or makes the Ethanol percentage low enough to not be able to penetrate the gunk or fuel lines.

Pretty much. Unfortunately, several members have already spent quite a while looking for replacements, and so far we have only one hope that has no ETA or really any substantial information of any sort other than "not yet."

So, we have to make due with what we have.

SilverDemon 08-01-2011 05:49 PM

I think I remember 06speed6 getting kicked in the gonads a few times with the response he received from them.....as to say they will never produce bigger injectors because we were not an "automotive manufacture".......

Good theory just manufacturers that size don't fuck with small fries LOL.

phate 08-01-2011 09:22 PM

Injectors...nothing like beating this horse again.

I haven't found anything of value in the VW/Audi forums. I hate sifting through their forums because it's a lot of ethanol bashing with nonsensical reasoning. Actually, I've done hours upon hours of reading through forums about running ethanol. It's pretty difficult to find anything substantial, especially anything pertaining to direct injection :(

bewsted 08-01-2011 10:37 PM

I spent like 2 hours reading the VW forums saying "You can't run it" "Yes you can" "Evo's run it"

Those guys aren't trying to hard for having a year on us to have figured things out.

Haltech 08-01-2011 10:39 PM

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.

bewsted 08-01-2011 10:47 PM

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.

JacksonMS30 08-02-2011 06:38 AM

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:

ccspeedsix 08-02-2011 07:01 AM

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.

ccspeedsix 08-02-2011 01:19 PM

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.

Maybe they can give a different perspective about this.

The injector size issue is not unique to running E85. Like @superskaterxes mentioned, he is pushing the fuel system as hard as I am, in terms of injector duty cycle, but with gas. There are plenty of other threads discussing this.

The gunk build up is unique to running straight E85, and that is the issue at hand (along with potential in tank pump problems).

I received the new in tank pump yesterday. @silvapain, depending on what my housing situation is this weekend, would it be possible to drop the tank at your place?

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

phate 08-03-2011 07:33 PM

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.

Mizzle 08-05-2011 12:23 PM

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.

Enki 08-05-2011 10:29 PM

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

phate 08-08-2011 11:15 AM

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.

bewsted 08-08-2011 11:19 AM

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.

phate 08-08-2011 11:32 AM

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 :)

bewsted 08-08-2011 04:16 PM

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....

Then... e40 here I come!

cld12pk2go 08-09-2011 06:58 PM

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.

http://i77.photobucket.com/albums/j6...R/080911-1.jpg



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:
http://i77.photobucket.com/albums/j6...R/080911-2.jpg



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:

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



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:

86AmishMs3 08-11-2011 10:41 AM

On a semi related note with the sludge, I'm noticing on my integra that pure e85 is drying out the gaskets and causing to become brittle when they go dry. But then again they are 150k miles and over 15 year old gaskets. Replaced them today when I switched back to stock injectors and gasoline was shooting everywhere. Sooo take that as you will.

Edit: fuel filter on my integra looked on par for 150k miles.

On my mazda, loves a 30% mix.

bewsted 08-11-2011 10:43 AM

30% is your knock eliminator and gives a lil extra pep for sure.

superskaterxes 08-11-2011 12:59 PM

so howd it go phate?

phate 08-11-2011 02:20 PM

So we dropped the tank, all went well. It only took a few hours. Everything in the pump assembly looked fine, except for the filter. The filter, which is a tiny POS on the inlet of the pump, was almost black with nasty dirt. It had so much sediment, it was very heavy compared to the one on my replacement pump. I am 99% sure it was the filter causing a huge restriction on the inlet of the ITFP.

But, I went ahead and replaced the entire pump assembly, only reusing the fuel level float. So we dissected the pump and regulator to look for anything odd. Every bit of it looked fine. All plastic pieces were intact, the pump motor spun freely, there wasn't buildup anywhere inside of the pump. The O-rings on the regulator looked brand new, and the rubber flapper valve was intact and functioning properly.

The filter material was still intact, and obviously doing its job. I am pretty confident in saying the ethanol is not eating anything in the fuel pump assembly. Though, it may be an indirect cause of the fuel filter clogging. I am unsure if this was 55k miles (total on car) worth of dirt, or 5k (total on e85) miles worth of dirt. In 5k or so miles, I'll re-inspect the new filter.

Aside from that, I have noticed significantly more buildup in the HPFP since the stock internals went back in and the ITFP started to die. It could be dirt getting past the ITFP filter, or it could be tied to cavitation in the HPFP due to lack of supply from the ITFP. I'm going to pull the HPFP tonight and clean everything. Hopefully I'll see this buildup subside from the current rate. I haven't been running the in-line filter for a few weeks, now, so I may put it back in.

On the positive side of increased buildup, I scraped together a good sample to send to Blackstone. I used a brand new razor blade to prevent cross contamination as much as I could. I'm going to compose a letter summarizing my entire experience. Hopefully they will be able to get some results. I'll post a copy of my letter here.

I have many pictures of the fuel pump assembly pieces. I don't have internet access at my new place, yet, but I should get it hooked up tonight. I'll post pictures of everything as soon as I can.

phate 08-11-2011 03:45 PM

Letter to Blackstone, sent today with the residue sample, 8/11/2011

Quote:

August 10, 2011

Dear Blackstone Labs,

What the heck is this? I recently spoke with Randy on the phone about this buildup I am seeing inside of my high pressure fuel pump. This is from a 2007 Mazdaspeed3 direct injection fuel pump. I recently switched the car to E85, and have been seeing this buildup ever since. I have been running E85 for almost three months, driving approximately 5,000 miles in that time.

Initially, I suspected it was dirt being dislodged by the ethanol. I put an in-line fuel filter in place, just before the direct injection pump, to no avail. The buildup continues. After 3,500 miles with the fuel filter in place, I dissected the filter to find not even a trace of sediment. I have found, however, that buildup occurs much more quickly without the in-line fuel filter in place. This leads me to believe it may be filtering some, but not all, of the contaminants.

Also, I recently had an issue with the in-tank filter getting clogged. All other in-tank pump components (pump/regulator/o-rings/rubber parts) looked unaffected. These two issues could be tied together, and I hope an analysis can point me in the right direction! Randy has already told me this is not in the normal realm for any Blackstone analysis. Please call to discuss possibilities – xxx-xxx-xxxx (cell phone).

Thank you,

phate – my client ID

PS – from what I can tell, after many hours searching through Google and online forum use that is bordering on obsession, I may be the only person running straight E85 in the Mazda MZR DISI engine. When the buildup isn’t causing a problem, the car runs better than it ever has. I, and the MazdaSpeed community, hope you can help us identify what this car will require to use E85 consistently, without the issues I am seeing.

Back in the day when I was running mid to high 12s on just a few bolt ons I was running mid 12s for afr and car ripped. Now I run 12.0-12.2 on pump 93 when Its in my tank.

It all depends on how efficient of a setup you have and keeping the bats down.

12.0-12.2 is farthest i've gone on 93 pumpzilla....

So I chopped the filter apart in layers:

The inside portion (pickup side) of the filter is dirty:

Just found out my new HPFP internals will be here next week.

So we all know what that means...because I don't, as they say, 'fuck around'. [LOL]

DYNO TIME

Just sent an inquiry to schedule for Thursday or Friday.

Looks like you might be just fine with a filter replacement and a good old fashioned scrubbing of the gas tank (if that's even possible). Maybe toss a gallon of methanol in there and swish it around for a few minutes to really get all the nasty shit out.

If you do that, take a pic of the result :)

Edit: New internals? What happened to the old ones?

Dano 08-12-2011 09:47 AM

Excellent idea!!!

The inside of the gas tank looked clean. There was a little bit of debris floating around, but nothing serious for 55k miles worth of fuel. Gas tank is back in the car with the new fuel pump assembly. It was definitely an issue with the ITFP, as I'm seeing 1900psi out of the stock pump when I get into boost a little bit. It can't supply enough fuel, of course, but I'm seeing way more pressure than I was before.

Internals were my first though, so I sent them in to KMD for warranty. Apparently they tested bad, as well, so I'm getting a new set.

Enki 08-12-2011 09:57 AM

Hmm...I'm wondering how they tested bad. Did they say? Hopefully they are actually still good, and KMD is just covering their bases and being awesome.

You could be right. Before I sent them in, I was told they would be tested for approval/denial. They just sent an email saying my warranty claim was approved, without explanation. I sent in a letter explaining how I tested another set of internals and they held pressure, along with a graph of my pressure loss over the rpm range.

PS - while Ethanol is not much more corrosive than gas, methanol is more corrosive than both, AFAIK. I don't think I would ever attempt methanol in a stock fuel system.

Enki 08-12-2011 10:22 AM

Yes, I'm aware of how corrosive methanol is, and I would never suggest running it in the stock fuel system; which is why I suggested you flush the tank (alone) with it, which should eat away anything loose inside.

Ergh; Edit:
That is pretty strange behavior by KMD. If I were you, I'd grill them a bit further.

phate 08-12-2011 12:25 PM

Ugh, no time available at the closest dyno. I'm going to call around, but it may be after the dragon trip when I dyno. I need to switch back to gas for the labor day trip to make sure all is well with it.

Dano 08-12-2011 12:49 PM

Don't they close the highway to let ppls run it?

socks 08-12-2011 03:28 PM

I did notice buildup. it was significantly worse than in the pictures above.

i didnt cut my filter apart, all i noticed was on the outside.

phate 08-12-2011 09:52 PM

So, I just spent most of my Friday night cleaning my HPFP parts. Everything was pretty bad. The housing and spill valve (minus the spill valve solenoid) was caked worse than when I first started on this venture. I haven't cleaned everything like this for many miles - probably over 1,000, but the buildup got much worse in just the last couple hundred miles.

Hopefully I'll be able to see some difference in build up rate with the new ITFP assembly and ITFP filter. I'm a little skeptical of the new ITFP filter, as it seemed like there was much less filter material compared to the old one. It was a different design, just like a single layer of thin cloth material, whereas the old one had a thick layer plus the woven mesh layer on the outside. We'll see, I guess.

phate 08-15-2011 09:24 AM

I've got some dyno time this Friday up in Seneca, IL @ Snowdance Enterprises. For any of you Chicago folk, this shop only charges $100/hr!! It sounds like they don't have any sort of tuner, so you'll be on your own, there.

Edit: looks like internals should be here tomorrow.

phate 08-15-2011 12:29 PM

I just realized they sent them to the wrong fucking address. WTF

Edit: Holy hell, I just realized this post is #601 in this thread!
