my fuel set up sucks....it was put together with used parts i had laying around. worked great for a while but doesnt like big power.

ive probably talked to 100 people on this subject.....and what one person says is awesome...the next person says it sucks. trying to get an idea of how much money i need to save up to redo mine for next year.

i have an sx pump on the car now.
i have an aeromotive pump new in the box.

both of these pumps seem to drop all of their effeciency at higher psi levels. look good on paper for an all motor car....but throw an extra 30psi of fuel pressure from a turbo car and they seem to suck.

weldon? expensive.....but seems to hold up good at high pressure.
ive been hearing of people running multiple bosche pumps?

are mechanical pumps legal? i doubt it.

i like racing too much to build just a T4 car...so whatever route i go i want it to be nhra legal also. im def. left scratching my head since you can't get 2 people to agree on the same stuff. i guess my question is.....who is running what, and whats working good? i know there are a few guys in the class making huge power. unless its top secret, post whats working for you!

 

Joe try looking at one of the more top end Aeromotives if you are having an issue with the SX (which I haven't really heard of even under 30 psi). The following pumps are top notch for Aeromotive (which was started with guys that used to work at SX).

http://216.242.145.16/products/product.phtml?p=2
That is the 11104. $425.95

http://216.242.145.16/products/product.phtml?p=1
That is the 11102. $609.95

http://216.242.145.16/products/product.phtml?p=10
That is the 13109. $134.95

http://216.242.145.16/products/product.phtml?p=9
That is the 13110. $265.88

The 11102 and the 13110 are meant to work together.

You should run a minimum 100 icron filter before the fuel pump and a 10 micron after the fuel pump.

http://216.242.145.16/products/product.phtml?p=41
12302 (100 micron for use with the 11102): $134.95
12304 (100 micron for use with the 11104): $94.95
12301 (10 micron for use with both pumps): $79.95

There is also a booster for the fuel pump that will boost fuel pressure in two (2) different conditions:

MAP pressure
Voltage

Always remember to run everything off a minimum 30 amp relay with 10 gauge wire ran for both power and ground.

Other than that you can go with any type fuel line that you want. Standard stainless steel, or the Pro-Lite hose form Earls as well.

Rough estimates that I can give you is about $1500 for a complete fuel system. That is what it has cost a few poeple that I have done them for.

Good luck Joe,

The Aeromotive Eliminator pump is AWESOME, it is what I run and has worked great for my power levels. Alot of people IN MY OPINION are close to MAXING out their Aeromotive A1000 since it is only rated for 800hp for Forced Induction, now that is CRANK HP not wheel.

 

are you sure that the pump is getting full voltage when you are making pulls. most large pumps require at least 8 guage wire from a 30amp relay connected directly to the battery. im running the sx pump and have no problems with pressure loss. also sx recomends at least a -8 feed and -6 complete return system. running the stock lines and filters can cause funny fuel pressure problems. i would try these first before trying a bigger pump. but if you allready have this setup then i guess the begger pump is needed our sx pump has no problem at 560hp, and we plan on using it with our new bigger turbo setup wich should be around 700. i think they rate them to like 1000hp or something huge like that.

 

If you are having trouble with pressure drop you may want to step up the voltage to the pump. This can be done by wiring the pump to the 14V alternator output with 10 guage wire.

Say your running a base pressure of 45psi + 30psi of boost. 75psi head pressure at the pump.

At 12 volts you get ~50 GPH
At 14 volts you get ~75GPH


This method is proven here:

Just make sure you have good lines and a proper fuel pressure regulator and you wont have any problems. Cortney green is make ~760whp uncorrected on the same pump, so it can make big power.

Joe,

personally I like the bosch pump set up that Art and Stan run.. We havn't really made big power w/ it in art's car, but I don't think it is part of the problem. I know stan has made some pretty big #'s so far and it hasn't had any trouble. They are really good high pressure pumps..

I like the Bosch 044 pump. It's a good high pressure/high volume pump, and doesn't cost a ton. Plenty of them on ebay.

 

Aeromotive Eliminator,10 gauge wire to 2 relays, powered directly to the alternater for an extra volt,1600cc injectors.

The SX line and the A1000 is crap over 550whp.

You really dont like the a1000? Cortney, Buck, and i think Jasen all run this pump w/ the full race sump set up. They are all putting 800 plus whp w/ no problems.

What problems did you see?

I think the A1000 will work just fine with a dedicated relay.

 

I'M REDOING MY FUEL SET UP AND I WAS THINKING GOING WITH THE TSUNAMI PUMP WITH A SUMP TANK AND -10 LINE WHAT IS YOUR OPINION ON THAT SET UP

Sorry Cort i swore when we were talking a few months back you said to get the a1000 from summit because thats what you and buck were running. Did you change or did i just have a brain fart? LOL Sorry man.

So when you getting a better turbo?

 

I just recently redid my setup with a A1000. Seems to be working just fine.

 

What works for some,may not work for others,it's all trial and error.

 

Joe,
I think you should look at the Bosch 044 pump, has the quality of being relatively quiet, can be mounted intank in some cases, and can do 650 wheel per pump. And the best part it is factory reliability.

Do you think running the bosch 044 inline with a walbro intank would do any good for more fuel or would the stock lines and walbro be a restriction?

 

I picked up an eliminator. very nice pump. that and a good set of injectors and even at 600whp i can damn near drown the engine with fuel.

You don't nessacarily have to run the bosch pumps inline, they can be run intank or external w/ a siphon tube(i guess is what you'd call it?) and you wouldn't need the walbro.

I agree with Sean. Its the pump I use. Tony1 calls it the baby pump, but I feel its better than the aeromotive.

 

wow..after seeing that SX fuel sheet Iam glad I went weldon!

mine (DB2025A) at 100 psi and 14 volts is 782 LB/HR with a 20.7 amp draw. according to http://www.kinsler.com

782 LB/HR is roughly 120 gallons per hour..

What relays are you guys using?
I burnt my relay with SX pump .

 

I hear people say they go straight to the alternator for more voltage. Has anyone measured this? I don't see why there would be more voltage there than at the battery, unless the wire from the alternator to the battery is too small.

For what it's worth, we went through 2 SX pumps on Allen's car and finally put a weldon on it. Been great since!

 

I think the reason people are picking up fuel volume by running a wire from the alternator is the previous wiring they replaced was probably factory(i.e. not sufficient for a high flow fuel pump)

 

Yeah, definitely, but picking up power for the relay from the alternator rather than the battery shouldn't make a difference in power to the pump.
