800hp with a 044 pump?
800hp with a 044 pump? Has anyone cracked the 800 rwhp mark with a single Bosch 044 pump. Trying to figure out my fuel system and only wanna run one fuel pump. Not really digging the price of the top name fuel pumps. It has to be inline fuel pump due to fuel cell I'm running. Would twin 255's be better than trying to squeeze 800hp threw a 044? Pretty sure I have -8 or -10 feed line now but will have to run a -6 return. Billet fuel rails with aero motive fpr. Running a 5.3l with billet s476r.
From previous experience in using these on 2JZ setups, I am almost certain the 800rwhp make is above the capabilities of the pump. I know 800rwhp has been exceeded using 2 of these and gotten to the 900rwhp mark. -8 should be fine for your goals.
Here is an article discussing some pumps including 044's:

What fuel will you be using? Something else to keep in mind is the fuel consumption for different fuels.

Denmah made 720 to the wheels with a single 044 and -6 AN feed line and 58 PSI base pressure. I believe he turned it up quite a bit more at the track and was probably close to 800 whp. This is the highest I've heard of on a single 044.
Maybe he will chime in with more info. I have no idea if it was knockoff or true 044. I never even considered the 044 for a 700 whp build until I seen his dyno and track numbers.

Only in the US do people seem to get those sort of numbers from an 044.
Everywhere else in the world they're a genuine 650 flywheel HP in a typical fuel injected turbo application. Some may get slightly more, but it is really beyond its safe limit.
But no way will it support 800hp unless perhaps you fired 21v at it instead of 12-14v.
You could do a pair of inline Walbros, or a pair of cheaper Bosch pumps, 909's or something.

Verdad Gallardo Ok. So I guess one 044 won't cut it. I will be running 93 oct. pump gas and 50/50 methanol mix in water inj. What is max hp on 2 - 255 pumps running together all the time? Won't be on high boost a whole lot but figure ill be at around 600hp mainly on street with a little extra(up to 800) at the track every now and than.
Here's the specs stock 5.3l with martins new 4.8/5.3 stage 2 turbo cam. 660 lift springs, retainers, seats etc. stock heads. Chinese head studs. Ls1 intake. Built Th400 with 3800 stall converter. 3.23 rear gears in built 10bolt. Hope it holds lol. S476r turbo with billet wheel and 1.10 ar. 2.5 crossover with 4" dump pipe.
I have a fuel cell and those 400lph pumps are in tank pumps. What about those speedmaster pumps on eBay ? Look like a a1000 but say good for 1000lbs hour.

I'd want 85gph worth of pump to hit 800WHP. IMO it would take 25+lbs to hit 800whp with your setup. So you need a pump that can put out 85gph at 68-70 psi.
Multiple 255HP's are still your best bet for cheap power with inline pumps. $91 each with AN fittings. A single 255HP pump puts out about 58gph at 60psi at 13.5v. (116gph for 2)
This setup was around $212 to make with cheap china AN fittings and pushlock hose.

If denmah made 700+ with 80lb injectors and a single 040 with a smaller cam than I'm running why would 800 be to far fetched if i fueled it with enough fuel. This is what im trying to figure out and need help with i dont want the fuel pump or pumps to be my limiting factor. Martin from tick said 800 should be achieved with About 18lbs of boost. I realize there are some limiting factors with my setup. I like the twin setup that is pictured there and the cost is nice.

An 040 is a dedicated in tank pump and flows slightly less than an 044
And an 044 at normal voltages is never supplying 800bhp unless the dyno is sprinkled with fairy dust or something.
The 775 number quoted in the link above is still high, but probably based on dead end flow, and not factoring in that some fuel flow will still return out the FPR.
