I am getting ready to put a fuel system in my car. I have all the parts needed except the external pump itself.

I know people have had problems in the past with some pumps malfunctioning or overheating. I have heard negative things about the Aeromotive A1000. What about the SX pump? Any others?

Looking for some success stories The noise doesnt really bother me too much.

Thanks, Jason

 

I am going with the next pump up the "Eliminator". I would also like to see what others are using or planning on using.

All said and done I will be over $1500 in the fuel system

 

i am running an aeromotive eliminator it over heated once had to small of a filter in front of it put a bigger filter in front of it no problems did install there electronic pump controller for street use just make sure you feed it with at least a 10 an hose and there 12302 filter

 

Hey Jason i'll sell you the A1000 i have had sitting in my closet for the last year... It just leaks fuel out of the electrical connection is all.

 

I've had good luck with a pair of Bosch 205LPH pumps, one internal in the stock location, and the other outboard off a sump at the rear of the tank. Second Street routinely uses these pumps... I have seen them use a set of 4 of them on a Porsche twin turbo running 30# boost. Each pump is good for 500HP at typical fuel injection pressures - I run 58psi.

The specific part # is Bosch 0580 254 984

 

i work in a speed shop were we sell various fuel pumps from weldon,aeromotive,sx,barrygrant,magnaflow,and others all pumps will have issues from time to time i bought my pump after talking with kinsler i looked at the weldon nice pump too pricey looked at the sx real nice pump i went with the aeromotive was the easiest to get i've heard the horror stories but have had no problems with mine once i got the right size filter in front of it little noisey but when you get to this level you have to take the good with the bad

 

thats a nice little bill to run up. what goodies did your fuel system get?

 

you need at least the 1104 jason, I prefer the dual walbro way tho.

also, make sure you run a STAINLESS filter before the pump, not a paper!

 

My planned fuel system. Prices are just what I have found looking and rounded up $0.01.

LS1Speed #CAS447 Fuel Tank $475
Aeromotive #11104 "Eliminator" Pump $420
Aeromotive #16302 Billet Fuel Controler $260
Aeromotive #13109 Bypass EFI Regulator $132
Jegs #128-10810B 1/2 inch Aluminum Fuel line $27
Jegs #128-10820B 5/8 inch Aluminum Fuel line $33
Aeromotive #12302 -12 Stainless Pro Fuel Filter $130
Aeromotive #12301 -10 Paper Fuel Filter $80

SOOO...$1557 Plus Fittings AND the following

Edelbrock Series #1 N2O kit $760(Hi pressure system)
Holley #36Lb/Hr Injectors $640
Hogans Fuel Rails $200

I have a long ways to go

THAT is JUST the fuel system!

 

36lb injectors for $640??

Ive seen 57lb'ers going for 480 new, was that a typo or ?

 

I chose Holley (mutec II) injectors on purpose. I would rather have a good injector and not have to fight the radical tuning differances then go with a cheap set and spend ten times as much tuning it in gas

I have tuned a few cars on the Bargan brand injectors, heck even on y own car. The diferance in the way you have to tune them is a major PITA.

I guess I just want to do it right the first time

 

I run a fuel cell for both the engine and nitrous. For the engine I have Magnaflow Pro Star EFI 600 and for the nitrous a Magnaflow Quick Star 300.

The info I have heard about Aeromotive pumps has been mixed both good and bad. I was told Aero pumps do not like heat and if near a heat source the pump will start to make noise?

I switched to Magnaflow after I spoke to my nitrous tuner about fuel systems. Series of test where done with multiple brand fuel pumps that where commonlly today and to make a long story short the top two pumps that performed the most consistant and provided stable fuel psi without fluctuation via a large fuel line dia. not to mention kept up with fuel volume demands under strong take off's and so on. The two pumps that where recommend to me to use was Magnaflow or Weldon pump.

Check em out.

 

If you want a reliable pump go with a Bosch pump. Right now they are probably one of the best. The biggest however is the 044 Motorsport pump...which I believe is only a 420LPH pump so if you are going to really be putting down a lot of power I don't think one will do it. I'm going to talk to some more people this week about putting a good pump in there. There was a guy in Austraila that was using a pair of them to power a 700+rwhp blown 347 Cobra kit car.

This is the problem I'm having right now working out the fuel system on my car. The one problem with the Weldon pumps....and probably the only problem is just how loud they are. If its a street car, it'll be louder than the motor. I've only heard a couple of them but my god its like a little power plant working back there. The Aeromotive and the such....there seems to be a reason many use 2 of them...in case one dies. While I don't have personal expericance with this I have seen it happen and have had to help friends swap them out. Good for a strip only car but thats probably about it. The newer stuff like the BG and MagnaFuel stuff....dunno...just haven't had any experiance with it.

Currently...my fuel system is pretty involved.
$1280 for a Fuel Safe 22 gallon Pro Cell (with level sending unit, 1 gallon internal surge tank,
$85 20' of -8 feed line
$80 20' of -6 return line
$120 Aeromotive boost ref. regulator
$60 in fittings and o rings for said regulator
$60 in 1x1 tubing for cell cage
$725 in Earls AN fittings (thats just the start of the list so far)
$350 for a low imp. driver box

Hell thats over $2600 right there and I still have injectors to get, and fuel pumps.

Granted now...it isn't a drag race setup and you could probably get away with some cheaper parts since you wouldn't really need the cell and all if it was just a street/strip car.

I'll see if I can't get some of the pics and stuff up of the progress in the next week or so. Once its all said and done I'll get a final list o parts and pictures

 

Odd.... the Bosch pump I mentioned above is "only" 205LPH, and it supports 500HP. Maybe I'm missing something here, but

420LPH / 3.78 = 111GPH

111GPH X 6#/G = 666#/HR.

Assuming you want 20% recycle/reserve:

666#/HR X 0.80 = 533#/HR

Assuming a thirsty 0.55#/HR/HP BSFC, the 420LPH pump will support 970HP.

Of course all that is assuming that the pump is flow rated at 3bar (43.5psi), which is where the Bosch 205LPH figure is arrived at.

Where am I going wrong?

 

You know....I don't even know myself anymore (hence why I'm still looking for a pump). I don't see how a 205 can support that much (at least not a FI car) as I ran the RaceTronix kit on the car and it died at 570rwhp (on a Mustang dyno) hence why I'm looking for a new fuel system because the car was only at 4500rpm when I saw the pressure drop. I've done calculations, I've seen other people's and I've heard everythign under the sun when it comes to pumps in the last month or so. When I orginally sat down and did all of the calculations the first time it would work out that one pump would just be shy of supporting 700rwhp. The 420LPH rating is at like 75psi or something like that, best I could find the pump is around 68lb/hr at 50psi...when I talked to Kinsler yesterday he said it was around 370 LPH at 50psi. This pump....as I have heard it is what was used in the Porsche 930 turbo Cup cars and has also when by the name of the 044 Motorsport Bosch pump. So if that was the case....with a 700rwhp motor you would need roughly a pump that would go 100GPH as you stated above. The biggest problem that I am having right now is the fact that I have not seen, nor can I find a set in stone answer to the ratings on the Bosch pumps. Maybe Speed Inc knows, because they have them listed on their web site.
