Lol, I hope not. I'll have to check it out when I get home. It was 12am when I finished and fired it. I was not in the mood to start troubleshooting. Hell, maybe the stuttering was my fuel pump failing.

Need a log of the issue to know for sure what's going on.

I am honestly scared to start it again. I'll give everything a once over when I get home from work and give it a shot. Looking back I wish I would have logged the original startup, fuck.

It's probably either disconnected O2 or MAF issue like what myself and a couple other speeds I know of have (MAF harness has to be moved slightly to make a good connection so the car will run properly)

@littleloogy; that socket set is shit. I broke 2 sets. I'm on my third and now just use it for light work no torquing or breaking stuff loose

I am so fucking stupid. This is why you don't work on your car late at night. My down-pipe was not bolted on all the way, no wonder my car sounded like absolute ass. My O2 sensor is definitely leaking though. I hear a tick in my engine bay. But at least I can drive my car. I'll try to fix the threads once I get another primary O2 sensor. Thanks @JgamB; for your help!

If you spend more than 1 hour at full operating temp and still have smoke in the cowl area, you have a leak from my experience, regardless how much solvent you sprayed. Unfortunately it looks like Friday for the O2, so hang in there.

at least it was stupidity on your part instead of a real problem

Loogy you get the primary 02 and coil pack today? Looks like you've cleaned up your issue in the meantime - just Nator that shit out as needed.

And run more boost and less timing, puppy turbo should behave better that way if it's really flowing more, and you can drop down to 25% or less Eth.

Yes I did! I can't thank you enough. What you did there was true NATOR spirit. I have not installed it, but still intend to later on. My old one is literally hanging in there by a thread. I just could not wait any longer, and wanted to drive my car.

I will push this puppy as far as I can with the available fuel headroom on full E, as I am still testing these internals. I will then temporarily change to a mix for testing purposes. :-)

I am traveling to Tahoe with the Puppy and IE internals installed. I forgot to pack my spare pump, SI-1 and my spill valve repair kit. 600 mile round trip. Kinda worried.


Sent from my iPhone 6

Haha, wow, this is the acid test now!

I have to be honest and say I'm already back on a 50/50 mix, because power. I couldn't really get more than ~305/~330 @ 19psi/5k RPM around without my IDC's reaching 100+. I was already quite aggressive with the timing to offset the lower boost, and didn't really feel like pushing it further, because I want to keep my engine in working condition.

On another note, how is your fuel level sender doing? I feel mine started to get a little weird today, not sure if that's because of it being out for so long and still "learning" (I doubt it), or if it's starting to mess up again (I hope not).

What AFR are you targeting? My IDC can hit 120 without problem. Plus you can tweet your Latency of you IDC to give you a bit more head room. What MODS?



Sent from my iPhone 6

330 whp should be easy with 12:1 afr target...which is what I'm targeting at well over 70 more horsepower than what you're making now (stock block). On full corn, just about everything you can do is "safe."

12.05 AFR. I was leaning it out to 12.2, but didn't notice any difference, and didn't want to go any leaner. I know we can go above 100, but with mine, above ~105 it starts to stutter a bit, and above 110 quite a bit more (plugs are good, gapped correctly, etc...).

Plus, with most of my driving being city/town driving, FL heat so A/C on all the time, MPG's were horrible. So 50/50 helps with that some also (read MPG tooning thread, modified cruise load afr's/timing, still sucky). When it starts getting cooler I'll probably go back full corn, just because I can now.

I will probably go back to my tune and try again, just not now here in summer. I step out into the sun and instantly become unmotivated to do almost anything.

Probably just need to throw some timing at it.

Okay. You make some valid points. You do what makes you happy and what you feel comfortable with. I just don't want you to give up on 100% E85 if that what you truly want to run. James and I are here to assist if you run into problems.

Something to think about: before I knew how to tune correctly and was fucking around I beat the living shit out of my car. I leaned to 12.4 targeting 20 Psi at redline. Car bucked like it was a nut tied bull. Calculated load was at 2.5 at 3500 RPMs. Drove that way for a while trying to get as much power out of it as I could. I still have the same compression I did when the car was new. So, I don't think you will hurt anything. There are reasons I run E like @Enki; said, It can protect your engine. When you start running mixes, that shield goes away.


Sent from my iPhone 6

We just don't know at what % you lose that bombproof feeling full corn gives; 50/50 might be just as good, and I might wind up going back to 50/50 for reasons of power as well. Time will tell, however.

Car made it to south Tahoe, and back. I am so glad I fixed my fuel level sender, makes driving the car on long road trips much more enjoyable.

I lost track of my mileage do to my turbo upgrade. I'll have to read through my notes and find my stating mileage. I know I am getting close to 3000 miles. No problems... Having a great time playing with my mid sized Air compressor. Up to 320whp with fuel headroom.


Sent from my iPhone 6

Puppy sized.

Both you @littleloogy; and @Enki; have definitely helped already, and I thank both of you for that.

I went and filled up full corn today, said fuck it and going to try this out. Aiming for 20mpg & 300hp just to start (300hp easy, 20mpg will be tough with my "conditions"). I've done some more re-reading in the MPG Tooning thread, changed up some things in the tune, and will be seeing how that works. If I didn't have to use the A/C so much, I'm sure 20mpg would be easily attainable.

Also, fuel level sender still works. Was acting a bit weird when around the empty level, and then stopped 1 bar short of full after filling up, MID range at 326. Then drove away from the pump, and about 15 seconds later that last bar filled and MID changed to 349. It may not be 100% accurate, but it works well enough, and that's good for me.

so these internals seem to be the fix for full E... looks like im selling my autotechs lol

For now, sure. If the seals wear enough, that might change.

Love these internals. Group buy?

Can't u just buy extra seals? Or do they not sell them seperately?

I am happy that the Puppy was able to suck more air then my fuel system can accommodate and that I did not waste money on expensive intakes.

Got my IE internals in the mail today...can't wait to install and see the results. I am reluctant to remove the kmd v3 internals that have about 50k on them though :( been working flawlessly.

Barely tickle 21 psi
Hit 1850+ multiple times during the pull
... put some of that normal people fuel in the tank, like 8 or 9 gallons of it - THEN you need a 3 bar *and* a 3" intake.

Although I am curious how you intend to spray Eth - none of the meth pumps are compliant, so carry on.

I almost went to a mix today actually, but I ended up leaving the pump on and walked into the gas station and buying some skittles. Maybe next time.

I have my eyes open for a 3 BAR with PNP harness, but the Warden saw my turbo bill and flipped the fuck out. So I must tread lightly on my car spending.

In the HPFP mod thread I'll be doing something funky with the HPFP. My goal is to modify the HPFP pump in a way that will allow a secondary fuel supply where I will be able to control injection with a valve set to open at a certain boost pressure. That's the plan anyway.

Take your time on the install. You only get one seal. Mine was really tight. I worked it in ever so gently.

Well, didn't even last 100 miles with 2 gallons 93 and 8 gallons e85. This is of course with no SI-1, nor the fancy RP oil. This was just with rotella.. Ill be taking the pump apart tomorrow to see what it looks like.

Damn, that blows. That RP dexos is some tough shit it seems.

Did you use rotella to lune the internals during assembly?

I doubt he did. The kit comes with a piston pre lubricated with assembly lube. I did run these internals on gas for a few hundred miles before making the switch to E85. Maybe the assembly lube is what caused the failure?


Sent from my iPhone 6

Sooo. To answer your question @Easter Bunny; I used the supplied grease to lube the piston. Took the pump apart, no black death. Pulled everything apart to find the piston and the inside of the cylinder lightly marred. Happens to be right where the hole is on the cylinder. I cleaned everything up real good before the install so I doubt anything metal was left on any of the parts. Only thing I can think of is if maybe the inside of the hole had a very small burr on it from being drilled from the machining process? Im going to email IE and see what they have to say. Hopefully they take care of me. I can run my fingernail over the piston and feel where it is marked up.

Installer error.

Could very well be. I've only installed about 20 sets of internals for all the locals. Maybe I need to do some more so I know what I am doing :P

I am interested in this big time. I only run 25% e85 right now but if I can up it, I certainly want to!

Well thanks for clearing that up. We have identified the problem which it is good to know was not black death. However for you its a much worse problem. Hopefully you are taken care of.

I ran 50/50 for over a year with no issues. Gen1 so no fuel level sensor issues.

Little Update:

IE just got back to me a few moments ago. They want me to ship the internals back to them so they can check the tolerances of the piston and barrel.

It's something.

Update, Just got this email.

"Hi Jake,



We received your pump a few days ago and were able to inspect it. It appears that the problem was associated with a tolerance inside the stainless nut being slightly out of spec, which caused the cylinder to move around, causing wear on the piston and cylinder. This is not a common point of failure and the first of its kind with our fuel pumps. We have been able to measure other nuts that we have here and they are all within specification, leading me to believe that this will be the only one.



We have gone through each and every component in your kit and replaced all items necessary, including the nut, seal, piston, and cylinder. We should have it boxed up and shipped back out to you no later than tomorrow.



Thanks for bearing with us on this and I'm sure you will be happy with the performance to come in the future with your IE HPFP!



Thank you,



Cassidy Williams

Forgive me if there are logs on other pages.
How close to commanded pressure does you fuel pressure stay?

@Tokay444; I'll have to compare to what they are now, but the last time I looked at it was within 100psi above target. At times I would get one cell that would spike to 150psi above target. I would not fall more then 30 psi below my target fuel pressure of 1669

I thought the nitride coating was what made this work? Black death doesn't adhere to the nitride coating or something like that. Chemistry fix!

I will probably try these eventually. Wish the price weren't so high.

Its the seal for the most part...keeps fuel and oil seprate, its a slightly different design from stock. Check out the website in op, worth the read.

Got my 3 bar installed today, and a catless downpipe on the way.

hmmm well I don't want to sell my internals just for this.... mayb ill wait a lil longer... Ima just try and use the redline s1 and see how it holds up

No good news to report yet, Apparently these are supposed to already be "broken in", but I am dipping down into the mid 1400s and I can feel the car stuttering. This is with 11.5 gallons of E and whatever was leftover from my previous mix. I am going to give them some more time to see if they need to be broke in further. May also try to use a different pump to throw these in but had no issues before with last set of kmds.

When you installed them, what did you lube them with?

Very light coat of the supplied grease

How many miles before you noticed the drops in fp, or was it from the start?

Put 17 miles on it new set before first WOT and it happened. Also took a Log at 50 miles and same thing.

This was also with a shot of red line in the spill valve...

Maybe try the whole SI-1 bottle in the tank, see if that helps fix anything?

I'm not gonna try that, as I don't want to waste what I have left. I'll try a different pump housing, and try a 50/50 mix. Idk so far I'm not impressed. Wish I was as lucky as @littleloogy;

I did run petrol for the first couple hundred miles. Before switching to E. That's the only thing I did differently.

Probably from the same batch as Loogy (I think) where the tolerances weren't right. Pull them and check for scoring. If damaged, get them replaced.
