Default E60 LPFP identification - 08-31-2014, 04:43 AM

Hey all,

I need to ask for your help. I rebuilt an E60 pump and have been waiting to get results back. Unfortunately the beta tester had some bad luck with his car and a tough schedule so they haven't installed it yet.

In the mean time I came across this but I can't tell from the pic if this is exactly the same as what you guys run. I've never had the drivers side assembly in my hands and would like to have one as well as a core passenger side assembly. The passenger side looks correct.

Can anybody verify this is correct and if so I'll pull the trigger on this. Then we'll get it out to another beta tester and see how things go.

Thanks,
Steve

Not sure if this will help

But these are from my car when I had the AEM installed

Thanks,

I think that's it....I'll order it and then I'll have a completely stock unit.

Sorry guys,

I have been away on several business trips and have been battling other maintenance issues with both cars for a while.
I will eventually find time to install the new bucket and lines with the Walbro 450 and post separately on performance.
Plan is then to run E60 blend with 93 and develop a custom Cobb tuning map for it (using ATR software.)
I ran E50 on the AEM pump, so I look forward to the expected power gains provided the pump performs as we hope it will.

Unfortunately the assembly I just received is damaged and it doesn't have the y connector...consequently it is going back.

What is the ETA for the working pump? When do you think you will come out with your new product?

I'm still waiting on Peder's results.

The other pump I just got in was slightly different and one of the lines had been cut. I attempted to return it but the seller just refunded it and said to keep it. It'll probably be good for extra parts but isn't a complete unit.

Once I have results from Peder...he's going to send me his old assembly and I'll start acquiring a few cores so customers will be able to swap out there pumps without any down time.

Steve, if you still need an OEM passenger side bucket with lines Andre said he has one laying around the garage. If you do let me know since I'm meeting him for lunch on Mon.

Also, just a best guess, with the stage 2 upgrade that Peder is going to test you think 100% E85 is possible with stock snails?

On stock snails it's always hit or miss. It really comes down to your tune, the HPFP, and a few other variables.

As far as the bucket, absolutely. I still have the one I recently got off ebay that included the filter. I believe the filters are the same so it'll give us a full system for bench testing. Let me know and we'll work it out.

Thanks

Cool. Andre is giving me the bucket tomorrow. I'll snap some pics and post it up so you can see if its what you need. Also I know Peder has the first setup for a E60. However if you need someone to test it if he can't I'm taking 2 weeks off work at the end of oct and wouldn't mind guinea pigging it. Just saying.

That's what I'm hoping. Right now im on the edge with my LPFP running a E45 map which is easier to fill, half e85 and half 91. I guess I'm lucky since the E85 stations out here are pretty consistent at being at E85.

You need meth. I can't run much e85 at all unless im spraying. At ~e37 I had issues with fuel trims, but pressures were great... 100% meth and a DO14 nozzle really supplement the fuel system nicely

I need a flash BAD

A quick update on this....

We received jwdominick's pump and filter assembly that he had sent to us (thanks!). We did some preliminary testing prior to disassembling everything and got flows of .8GPM @ 13.5V and 72psi.

We then installed a new Walbro 450 pump and tested that under the same conditions. The flows with the new Walbro 450 installed were 1.0GPM under the same conditions for an increase of 25%.

The stock pump in these buckets is an oversized Bosch turbine pump that is much larger than the 1 and 3 series are utilizing. Just like the 1 and 3 series, there are 2 venturis and the configuration is fairly similar with the exception of a Y adapter that splits the supply between the filter assembly and the venturis. This likely explains the oversized Bosch pump and the reduction in flows with the Walbro pump as this system seems to be less efficient. Not sure why they did this other than potentially due to the larger tank, deeper drivers side well, and the lift required to return fuel from the driver's side to the passenger side?

We are ordering in some additional tooling and hardware to button everything back up and hope to have this out to Jeremy for testing in the next week or so.

is that 25% increase with e85 or just regular pump fuel?

Neither...we use mineral spirits for our bench testing.

That was also a 25% increase in flows...not 20%

FYI the specific gravity of:

Mineral Spirits = .74
Gasoline = .74
E85 = .79
Water = 1

Yes it was, sorry bout that

So if our pump flows unleaded fuel just fine, and ethanol requires about 30% more flow... is it safe to assume that this pump would allow us to max out the hpfp on e85 since it flows 25% more... obviously not straight e85, but perhaps 80-85%?
I honestly have no issue relying on meth as a fuel supement, so all im looking for is something that would let me run enough e85 to take care of map 7 boost levels, and I could go more aggressive with map 3 for track days or if I upgrade turbos in the future

Good info. Just curious Steve what setup is Jeremy running on his 535? I didn't see his post to check his sig info. Also thanks for continuing to try to help us out with our elusive fueling solution.

So you want to know if you can run 85% of an 85% ethanol blend...or 72% ethanol?

On greater percentages of ethanol content I'm assuming you'll also be running a more aggressive tune and making more power?...I didn't see that in your equation.

Our expectation is that you'll now be able to max out the HPFP. Beyond that, your individual variables are going to come in to play.

Lets see how Jeremy's testing goes and go from there.

I'll let @jwdominick give you his mods as they aren't listed in his sig. If he doesn't see this...I'll ask.

And no problem

Are you not able to use a E30 mix for some reason? From my logs I can usuAlly run up to a E40 mix with no issues. Currently though the E45 mix and aggressive map I'm using is putting my LPFP into a early grave so a upgrade is really needed for me to keep ripping it up.

Well in the past I had issues with not much e85 at all so I gave up. This summer I found that my limit was about e37, but only bc im spraying meth... I never had a flash until this last week, and now everything is e70 junk so I haven't got a chance to figure It all out yet

I think I could probably pull it off, but not enough to replace straight race fuel

You should be able to run a E30 mix without having to use meth. If you are using the backend flash via a AP then you should be able to just change your fuel scalar to a E30 mix, iirc 1.10 banks 1&2, using the cobb ATR. If there is a more involved process I'm not sure since I only run a Cobb flash map using ATR.

Ahhh okay. Well I can't help you there. Maybe reach out to Ken to see if he can help you with getting a proper E30 flash so you can have fun. Also make sure you test the E85 in your area because I just tested the place where I get mine and it is still around E85-88.

@SteveAZ - if the testing goes good Andre already hooked me up with a bucket for some fuel lovin!
