Sorry for the double post about the same topic guys.
your best bet would be to either run that single magnafuel pump or a weldon pump, i know for a fact a single weldon pump is proven on methanol.

if you can handle the noise i would go with a dual pump parallel 044 setup.

the weldon is also a possibility, will run about the same as the twin bosch units. i just don't know about it's durability for street driving and would be hesitant to use it for long periods of time since it is more of a race pump and haven't seen it used on street cars. they claim it can be used on the street with a modulator, but why would it need a modulator? because they are trying to cool the pump when higher flow is not needed, which doesn't sound like a good solution to me.

slightly off topic but...

retrieved my FD from Beyond Redline in Green Bay, Wi yesterday aft and drove it home. my first road trip w E85. actually around E77 according to the FFS.

100 miles, 5 gallons of fuel consumed. mostly 73 mph highway and in the 14s AFR-wise.

cage and race seat/belts w a race exhaust so it was an interesting drive. fortunately didn't talk to any people in uniform.

impressed w the MPG but won't be running E85 unless on track.

Why won't you use it unless its at the track?

I run twin 044s mounted to the back of the diff cross member with a sumped tank. Can barely hear them outside of the car, not at all in the car.

you are running to rich at bring your a/f to 14 at cruise and at full throttle mid 11 and you would get better mpg.

Hi Howard for your reference

136 W Scott St, Fond du Lac, WI
BP Station with E85
Around 3 Miles From the Taycheeduh beach location.

Has a Single E85 Pump, They dont list their station on many of the E85 Sourcing Sites.
In case it was overlooked

So what about a Fuelab 42402 pump? I'd rather keep it single and simple.

Fuelab pumps do look like a great option. One of the local guys is running one on e85 and very happy with it.

i am expecting delivery of my Borg Warner EFR 9180 this friday and am sure happy i made the switch to E85. i plan to be on the dyno as soon as possible after it arrives. it will be interesting to compare the output and other data with my GT4094r.

Can't wait to see the results! The EFR 9180 should be the ultimate compromise between response, huge mid-power and huge peak power potential.

Anyone dabbled with or know anything about the Pierburg 7.00228.51.0 E3L aka "Veyron" pump?
I just bought one to replace my 044 as an external mount. Looks good apart from the pissy little 8mm outlet.
There is some info here, a flow vs pressure chart (of unknown origin) about half way down Don't have enough fuel pump? How about one from a Veyron!

Walbro E85 pump PN 9000267

static 43.5 psi

let's use 30 PSI of Boost and see what it flows at 13.5 Volts

according to Walbro: 364.5 L/Hour

translated: 6075 CC Per Minute

that is NET FLOW.

grossing it up for lag and 85% max duty cycle means it will run 8200 CC worth of injectors at 30 PSI of boost at 13.5 V.

6075 cc per minute is 1.605 gallons per minute

doing gasoline, that is 10.19 pounds per minute of gasoline.

at 10.5 AFR we get 107 pounds per minute of air, 1548 CFM or 806 rotary rwhp.

converting to E85 on a BTU basis

82,300 (E85 BTU) / 116,090 (gas BTU) = .715

806 rwhp X .715 = 576 rwhp at 10.5 AFR

576 at 10.5 AFR
603 at 11 AFR
630 at 11.5 AFR
657 at 12 AFR

all of the above is at 13.5 volts as per the Walbro site.

hp was converted on a BTU basis. E85 may be more or less efficient as to conversion to power from latent BTUs. i look forward to empirically deriving this relationship on the dyno shortly. according to last year's data E85 is more efficient versus gas than the BTU relationship but i would like to have more data.

if you add a Kenne Bell Boost A Pump, which runs ONLY in boost and set it for 17 V you add more than FORTY PERCENT to delivery. just make sure you have large wiring, a sufficient relay and a 30 A fuse.

here's a great tech read from Kenne Bell.

Yeah, pretty stupid question but the ebay seller isn't likely to have much info on them, not much to be found on the net either except they apparently flow about 3/4 of a cubic ****-ton, and some supra guys think they are getting close to a 1000hp and 1200 with a ken belle gadget strapped to their ***** - grain of salt there AFAIK, I'm just wondering if anyone has any real world experience with them

here's a chart on my Walbro E85 pump running at 16 volts powered by my Kenne Bell Boost A Pump setup from last Oct...

GT4094r, boost around 25.5 to 26 at 575 SAE, 588 STD rwhp

from 7239 to 8911, the greatest difference between rail pressure and boost was...

seven tenths of one psi.

i will be further testing the fuel delivery of this setup shortly w my BW EFR9180.



fuel pressure is absolute on this chart so rail pressure was approx 39.

What wastegate are you running with the GT4094R and E85? I had mine on the dyno and could not keep the boost down over 5700 rpm. It started climing, even tho the ECU was set to only 12 psi. It maxed out at 17.7 at 7000 rpm. Im running a Tial 44mm now plumbed bak in right before the first mufler.



So we aborted as i realy don't want more then about 500 at the wheels. And as we now have 583 at the crank that's more then enough. And 593 nm wich is also alot.

This is a BP engine with 44mm runners and a 44mm wastegate with the 1.06 exhaust housing on the GT4094R

Whats the lag for fuel pressure for the Kennbelle? What I mean is, lets say the booster turns on at 7 psi and before the booster was installed you saw Fuel Pressure drop at 9psi. Is there some type of formula for setting it up.

Greetings Jan,

"What wastegate are you running with the GT4094R and E85?"

i run one Tial 60 MM. no problem controlling boost, it does re-enter the exhaust. i am currently running a 17 psi spring and can manage boost with no spikes to 29 psi using a 3 port solenoid.

it sounds like you are running one 44MM WG?

if so, my 60 mm has 86% more piston area.

4.38 sq inches to 2.35 sq inches.

most people running turbos above 65 pounds per minute run either two 44s or a 60.

BTW, 2 44s have only 7% more area than one 60...

as you know Tial offers an endless amount of WG springs. you could consider dropping down on spring pressure. were you running w the controller off or on? if it was on it could be the settings but i do think if you have only one 44 mm WG that could be the cause. i really like one 60.

you mention 44 mm runners... are you saying that your turbo manifold has 44 mm I D runners? if so, that sounds like a mismatch w a bridgeport.

fuel pressure problems generally are not associated w the early stages of a pull. they generally show up as the fuel injector on-time ramps w higher rpm and boost. for example you might be at 14 mS in ramp and 25 mS at full boost and rpm.

the BAP triggers as soon as you are in boost. it is not progressive but you are able to pick a setting ( from zero to 50% V gain) for V boost. i have always run plus 20% or about 16 V. a 20% increase in V adds around 30+% to flow. since FDs have a return system the unused fuel simply cycles back to the tank. if you aren't in boost your fuel pump sees normal voltage.

of course your fuel pressure regulator does it's job presenting the proper pressure to the injectors. the BAP simply makes sure enough fuel is present.

Thanks for the input Howard, im thinking that the 44mm is too small also. As the duty cycle on the autronic was showing 0% at 6500 rpm and 10% at 6000 rpm. 0% is fully opend. And it can controll the boost up untill about 5800 rpm. When it starts to clime alot.

Also another question, how much higher ignition are you running on E85? As you have like 150 rwhp more then me at 4000 rpm. I do have a big BP so it's got lower grunt.

The tuning is 50mm outside diameter, and i belive the walls are like 2mm or something. So perhaps 46mm inner tubing diameter.
