What do you think about running this set up ...
Image


the fuel pump will be the Aeromotive Eliminator with 160lb injectors... Will be running a fuel pressure of 35psi at idle and 70psi at max boost. And the fuel pump will have a constant voltage of 13.5volts...

Let me know what you guys think ...

Justin...like the setup its similar to what I want to go with except I won't have the dual draw and I'll run -10an to the block then dual -6an out (I don't need as much fuel as your crazy butt :lol: )

What is the reason for the split draw?

ok ok ok... now you are just showing off. :)

I agree on the dual draw setup - it seems that you should choose the 'best' spot and stick with it. How are you going to make sure that no air is drawn from one of the ports if it is exposed to air?

Well If you any of you have actually seen the fuel tank of the camry/solara/avalons ... Its a saddle bag design; the driver side is the lowest point to draw fuel. Now If you look at the center of the tank... on the driver side... it is the absolute lowest point of the tank. The problem with that is if you accelerate off the line the fuel will sloush backward and might cause a low suction pressure ... Thats the reason why I'm running a split draw because of how the camry/solara/avalons fuel tanks are designed...

if you look at the diagram thats why theirs a sump draw... Which will hold at least 1 gallon of fuel in it at all times and it is placed at the lowest point on the tank. The problem with this is it might be too low and might have clearance issues... sooo I have to really sit down and look at the fuel tank for about 10 minutes with the WRaith on the floor...

Charlie your just jealous that you can draw as good as I can on paint program... :nana: :wiggle: :lol:

ok i'll officially never quesiton Justin again :lol:

Wraith, how come you dont run a surge tank instead, say about 2L, so it'll be tank->draw->filter->pump->surgetank->pump->filter->fuel rail...something along those lines...that way any sloshing of the fuel doesnt affect the fuel draw. also you might want to have a spiral design in the sugre tank also. if you need any clarification just tell me, i've got the info some where on my home comp and i'm at work right now...

Cheers :)

I know what a surge tank does but that setups are more geared for road racing cars. And it has alot of flaws that could be costly. One flaw is your relying on 2 pumps ... What do you think will happen when the puller pump stops working... The pump after the surge tank would still be able to pull just enough fuel to keep your car running. But once you hit boost, then there goes your motor. You have to remember these pumps are self priming and can work on dry start ups.

Another thing with this design is your have to think of the horsepower I'm going for... With the configuration of my setup, I would need to run 2 Aeromotive fuel pumps to keep everything full and not sucking air... Which would be too much money...

Trust me .... I've looked and research ever avenue of doing a fuel system.

I believe this system is similar to the fuel sump that Fullrace makes for Hondas? That's how most external pump setups run from V8 guys to Supra folks. This system will work great and possibly the best system in the performance perspective. But again, I am not a fan of external pumps due to a couple of reasons though. First you mentioned ground clearance problems, second is having all the fuel components under the car is not practical for a street car. Some people say it's dangerous especially for a lowered vehicle. For every day car, having all those wiring exposed to severe weathering is not the best thing either (which is why there are barely any wiring in the undercarriage on OEM cars).

Well, I guess this doesn't apply to your Camry that much...rofl Since I doubt it will be anything near a street car :naughty:

Good stuff :thumbup:

hey tony ... I wont have everything under the car... I'll have it in the trunk soo no problem with ground clearance... just have to cut up the spare tire bin in the trunk to make it work

i was asking him. i dont want to hear anything from you. your post is useless. it has no info in it. it adds nothing to this thread. if Justin thinks that it has too many drawbacks i would like to hear what they are, because thats the setup i will be using, with a 12 or 15 gallon fuel cell in the trunk instead of the stock tank like he is stuck with. i would like to hear his opinion about it.

why not run 2 pumps, 1 on each line with 2 filters or 4, and then the return setup the same.

i just briefly looked at your diagram. and havent read the posts yet. but on my civic, i did 2 -8 from a sump to a y block to a -10 to a 100micron filter to pump to -10 line to a 10micron filter halfway under car(fitment isues is why its not right after the pump,it used to but but exhaust was too close) to -8 line to fuel rail to fuel regulator to -6 line to stock return line. thats how mine is set. and i think the -12 is over doing it. aeromotive is a -10 fitting on the pump and filters.


*edit*
ok, i have read the whole thread. i wish i just did that at first. im going to be quoting alot. haha
dang. just noticed this isnt like other forums with the thread underneath anymore. so sorry since i have to do multiple posts.

are you saying that it works dry also? from experience, just dont let your gas tank get too low. it will mess with the fuel pump. it wont push enough pressure out to start your car or run your car for a while. you would have to let it sit and prime itself up. like an hour or so if its completely drained while driving. now if you just installed it, and prime it you are fine. but if it pumped through the fuel system on empty you will have some down time where the car wont get enough fuel even after you fill it up with fuel. it will take a while for it to work again.

ive been driving my civic fine. and lately oklahoma has been having reeally hash weather. and i ghetto wired up the wires for temporarily. not knowing the weather would be this bad for the past 2 months. its fine as long as you check on your stuff every once in a while. theres no problem with it being too low.

when you say that, you mean you are still going to install it on the outside correct? im asking because, i believe it is against nhra rules to have your lines and pump inside your car. you have to have it on the outside underneath, or somehwere located out of the interior. thats what i have been told from whom i bought the system. i have really looked it up. but im hoping you are meaning you are cutting up the wheel bin to raise it and have more clearance correct?



other than those. i dont think there is anything else. but good luck with your setup and what you are doing. i still think its overkill for the first 2 lines. haha
