Cheapest/easiest fuel pump set up for 800hp?

[cschepp]

Ok but say you would only go for for more the 5-600hp range for a dd, would a single if not two tomei pumps suffice? I understand the purpose behind it but would this be needed? I understand it's a safety measure to do a swirl pot.

And yes Daryl Jon isn't from Ontario but I think he ended up making between 500-600awhp anyways and I'm sure he is happy with what he accomplished based on his videos.

So here's the poop on my car.....

NOT twin Tomei's in the tank.......twin stock pumps and stock hardlines...........see my sig....


If my car can do that on such pathetic fueling equipment then an A1000 is a cake walk. I know of 4 dudes running the A1000 and not one of them use the speed controller and not one of them has hot fuel. I don't think it's that big of a deal, especially with a surge tank. Using a return line that is the same or bigger than your feed will help this too.

If I was to go that route I would use a Kenne Bell Boost-a-Pump. That way you are totally covered up to 1200hp at a fuel pressure of 70psi (45 base plus 25psi of boost).

Jon is right. the controller is not needed. i got a little excessive on my fuel system but im happy i did, its beyond enough fuel for my set up and it adds a safety layer that helps me sleep at night. only complaint is that the pump is pretty loud.

I didn't read all the way threw the post but has anyone suggested just running a 400lph walbro or the dw/aeromotive 300lph in tank and maybe upgrading the lines. should be enough fuel.

The stock fuel lines with a Nismo FPR are good for over 500awhp. I don't think they will limit you running -5 turbos.

Funny you mention that, I held an in tank 300l/h pump in my hand at lordco the other day and it was the same size as a stock Nissan pump. Twins would be good to 1000hp easily if "hotwired" and be only a little bit louder than stock. The best part is that they are dirt cheap.

I see in your pick that you have the pump screwed right to the trunk floor. That pretty much is like hooking it up to an amplifier and turning the knob to 11. Use some insolated rubber mounts and the noise will be much less.

I threw away the stock rail and lines 3 years ago. Went with -6 all around with Tomei rail/fpr, 800cc injectors and tomei intake fuel pump. Was told by the tuner I didn't have enough fuel for 550whp so rather than arguing or looking for a new tuner (due to ecu having limited tuners nearby), I'm making sure I can't be turned down for ANYTHING (other than stock gearbox lol). If my tomei pump with water meth gets me to near 550whp lets say (on -5s) and my meth failed, there wouldn't be lots of fuel available to dump in for safety... I'm too cheap to run race gas and a separate cell for it. The meth is more for safety and a bit for added power.

So, I took off the abrasive -6 lines, tomei rail, 800cc injectors and tomei fuel pump which are for sale.

Now (for the time being unless I roll back to the thought of a single...) going with:
Bosch 040 intank pump to 4L swirlpot (no pump controller)
twin Bosch 044s (since more than 90% of big power GTRs in the world run twins and not big singles) feeds a -10 (or 2 -6, not sure on this yet, I have enough hose for either), through a framerail mounted fuel cooler then split to twin -6 and a -8 return.
ID 1000cc
HKS rail
Tomei type L fpr
I might run a fuel temp gauge more out of curiousity really...

A1000 or 1100A flow too much for my hp goal and would circulate excess fuel for nothing.
Should I have issues with the twins (if it doesn't kill engine #3), I will swap a few lines and go with a Weldon 1100A and controller.

Yes I'm crazy... No it's not a race car, just a hobby for the meets on sundays rofl... probably wouldn't pass a safety at the tracks since I don't have a rollcage.

Im running 2 in tank deatschwerkz 320 lph fuel pumps to 2 -6 feed lines and a single -6 return. Works perfect. Also 1 fuel pump failed on me and caused no issues just replaced it on warranty and off I go again. I'm also running a check valve system.

My setup definitely recycles the fuel and I've never had a problem with so called hot fuel...

I thought of that but because I like heavy cornering and don't always have a full tank, I have to do an external pumps and a swirlpot, don't want to run dry. The factory tank is poo.

At 320lph each, you probably didn't have issues when 1 failed cause you don't make 500+whp

[newalliance123]

I can't do a pull below basically 1/3 tank. That's why if I have time this winter I will switch to a swirl pot way better then being on top of your gas ALL the time.

GTR_Dad was making over 500whp on -5s with no water/meth injection, stock fuel line and Nismo FPR. No water meth injection either, just 94 octane husky fuel.

That being said, upgrading to the -6 line and 800cc Injectors would be plenty of fuel to make running out of water/meth safe. Might have been cheaper to buy yourself a boost controller that can react to problems and drop boost pressure on the fly.

[newalliance123]

Husky has 94 Octane now? I always heard from my VP rep that husky had the best gas but last time I checked it was only 91 or 92. 94 at husky would be awesome, I hope its like that in BC now.

Husky/Mohawk gasoline in Alberta is an ethanol blend. I'd rather have straight 94 octane gasoline but nobody sells it here. Still decent for making good numbers without water/meth on a GTR.

The water/meth would be good backup if you had to run a tank of 91 octane fuel if there wasn't a Husky/Mohawk nearby.

[gtrjon]

since i drive my gtr in the states alot i got retuned for 92 octane which is the best that is accessible in the states. it also contains ethanol which is in comparison to the 94 octane i originally got tuned on from chevron with no ethanol. this way when i go to the states i can run 92 with no problems and when i drive the car up here i can run 94 and run a little rich. its better then the other way around where if i went to the states id run lean. however i lost 25awhp at low boost switching to 92.

[Willis]

I think I will get tuned on Shell 91 for the same reason. I have a 6 port water/meth injection system, so might as well use gas I can buy anywhere. The water/meth should let me run full boost no problem.
