500rwhp fuel set-up
I've been searching and still very up in the air what to do for my fuel situation.
Im looking for hopefully 500rwhp with my aspec gt3540r with 2x850prim. and 2x1600sec. injectors, aeromotive fpr and right now I have the rp competition fuel pump. I realize I need to either to duel in tank pumps or an external. Im leaning towards the a1000 aeromotive external pump and I would like opinions on line sizes and any other usefull information!
Thanks

with stock fuel lines.
Ive written a post on my findings a while back.

edit: boby that dual pump setup you have looks very easy! Can you tell me how you have the pump wiring setup? I see you t'd into the main fuel line from the secondard witch is way easy however the wiring just has me a bit confused. Did you just splice into the original ground and positive? Oh and is it better to have two of the same pumps or could I use my rx7.com pump and a walbro?

I am also looking into the making sure I have fuel for 500RWHP. I guess I am very leary of dual pump setups. If a pump goes down you would have lower fuel pressure than expected at boost, and wham bam rebuild time. I am going to stick with one pump or may try the MSD boost a pump. I know several have you used the boost a pump with success.

it really is crazy how much more fuel the rotary needs compared to equal power output from a turbo piston setup. we can get 650whp from turbo hondas on ONE... yes ONE walbro!!!! i prefer the dual intank pump setup as we have had a few a1000's die on us

I run dual intank walbros, put them in parallel for the wiring. I run them with 100% success using a 30 amp fuse and the haltech relay.
The pumps draw a lot of power even at idle; at my 1300 rpm idle you can tell there is not a lot of voltage. I have an FD alternator as well.

He said the specs are 1000 -1200 n/a on a piston car 800 turbo charged on a piston car and 500 maybe a tad more on a rotary. Can anyone confirm this? I thought it was a little strange. www.wwrturboinjection.com

Quite simple to hard wire the relay to the battery if you’ve relocated the battery in the back like I have.
Yes I have T'd the two pumps inside the tank so that the tank inspection cover does not need to be modified.
I don’t see the harm in running your stock pump in parallel with a single Walbro instead of two new pumps, apart from being old and tired and perhaps ready for retirement.

A1000 is loud but will flow the fuel you need for your setup. As long as you setup it up correct and never suck any air through it then it will work well. Whoever said the A1000 isn't enough but to run dual walbro's is a moron. Look at the flow charts and you will see one A1000 will flow more fuel than dual walbro's.
Another nice pump to look at is the Bosch 044, very reliable pump that alot of track teams run.

THey fail because people reduce the line size and restrict too much flow...
Going from -10 outlet to -6 outlets will make them capsize. Easy way around this... run -8 to the firewall, and then use a Y-block to run dual -6 if you want to stick with -6 to the rails.
I will be using -8 all around, but I am using the eliminator pump and feeding it with a -10 inlet (normally -12). I've been told the pressure drop on -10 is just ridiculous - the pump can flow that just fine, but it's going to be a pain in the ****. I've decided to run -8 hard lines, and feed it with a -10, have -8 to the rails, and probably a -6 return (return never needs to be that large because you're using a lot of fuel anyway)
Just my $.02
The A1000 will do 600hp on a rotary, since LUPE did that and he had an A1000. He made 603whp.

i like simple wherever possible. i don't know what Ari Yellen is running in his 700 rwhp drag car at the moment but i do know he was running OEM steel fuel lines recently. he said they worked fine.
i run 850/1600 and i digitally log fuel pressure so i know EXACTLY what's going on in all 400 Power FC cells. i have run 90% injector duty cycle w my setup with no decrease in fuel pressure.
i run a cosmo pump and a Kenne Bell Boost A Pump ($200). the BAP, in boost only, juices my cosmo pump from an adjustable zero to 50% increase in volts. i run plus 20%. i have run the BAP for 3 years.
visit kenne Bell's tech rich site for additional info.
since adding my methanol injection in july 06 i am now down to around low 70s injector duty cycle making the balance up w methanol.
no knock. 1100 preturbo egts.
happy motor.

Also for the record, I was making 490whp with 850/1600cc and methanol.... stupid, stupid, stupid rich. Running stock hard lines and -6.
I mean I'd get into boost and my AFR's were in the 8's - if it wasn't tuned so rich, I'd easily make 50hp more at same boost level. I've seen people make 600hp on stock lines as well.

I know all the big dogs are running mechanical fuel pumps but your talking 800 bucks for the one they use so I'm not even going to go there as I'm not seeing near that kind of power. Seems like the kenne bell boost a pump or the twin intake pumps would work the best and have the best results for the buck. I'd still need some sort of diagram before I'd want to wire up the two pumps.

I am wanting a pump myself that can do 550rwhp or so. I am wanting to do an external that is reliable. I have been also looking at the a1000 and would love more input.

I have 4 x 1680cc injectors and a highest rating SARD racing in tank fuel pump that is rated at 280L/hour @ 12.5 volts
Will be keeping stock hard lines and not changing these, looking to run 35psi on my fully built 13B & TO4Z 1.32 set up on 60mm HKS GT2 gate, expecting around 800~850bhp (what ever that is in your rwhp language *take your pick*)
