To start off I don't want to do dual intake walbros just to get that out of the way.

I've seen people do twin 044's by using a tube in place of a intank pump, but I'm not sure a stock sock will give enough flow for my HP goals. Anyone have anything to add?

 

dual 044's is the way to go. check out this thread https://honda-tech.com/forums/showth...highlight=fuel

 

why dont you want the dual walbros just out of curiosity

 

had a buddy do it and its more of a hassel then its worth in my opinion

 

What fuel? Gas? or E85?

Twin in-tank 255's would support 800 whp on gas, only con would be 70 psi will be your max fuel system pressure (ex. if you're running 30 psi of boost, your max. base fuel pressure could only be 40 psi).

Without sumping the tank, that's probably the easiest & most economic way.

 

IMO you dont want both of those 044's drawing fuel up and out of the tank, although they dont need to be gravity fed it seems like alot to ask of them.

 

You're touching on why we always recommend gravity feeding:

I think we can all agree that "suction" is vacuum.
Now, when you put liquids in a vacuum, you lower the boiling point of them.
The more vacuum you put it under = the lower the boiling point.
This should be easy to understand since the cooling system in your car works exactly the same, just in reverse (pressure raises boiling point).

Now, gasoline is already volatile at room temp, this should be easy to understand as well since we all know how quick gas fumes will overtake a room. So it's very sensitive to vacuum and heat only compounds the situation.

Regarding inlet/pick-up sizes: obviously the bigger you go, the more volume they'll carry.
The more volume = more weight.
More weight = more vacuum.
More vacuum = lower boiling point.
Till you hit the threshold of cavitation (dependent on all combined variables)

And if you're parked on a 120+ degree blacktop parking lot or paddock, your fuel will already be pretty warm lowering the threshold of cavitation even more.

If you (OP) did twin 044's the way you described above, A. we still wouldn't recommend it, and B. you'd certainly want to use two tubes, one for each pump.

 

My buddy made 854 whp with the dual walboro setup on c16. I helped him install it and it was no hassle at all...?

 

dual walbro is the easiest thing to install, out of all the upgraded fuel options. the only problem I have with mine is I keep burning up one pump to a crisp and cannot figure out why, I am on my third pump, maybe I should change the gauge of the wire to 8guage,

 

I would also like to hear some more recommendations.

 

Just sump it and call it a day it's cheap

 

Damn that worries me Im thinking of going the dual 255's over the winter. Anyone else have this issue?

 

well after more research I'm just going to sump my tank and do dual 044's thanks everyone

 

never heard of that issue and have seen countless cars with it im currently waiting on my fuel lines to the car myself... the kit if self explanatory you jus thave to put the punps in one at a time cause of the size.. i think whoever otld htis guy the twins gave problems was being lazy or embeleshing

 

here you go op.. not bad price.

sure...we will see how many times you change your mind before tomorrow haha

 

haha screw you steve the Rrr will be waiting for your evo

love you buddy
