Best fuel setup for 800+ without a sumped tank??
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

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.

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,
