Yeah have had a few make that much on a single 044. The fuel pump isn't the only piece in the puzzle though. Make sure you go slightly overkill on the injectors and make sure the tuner knows what he's doing. I recommend EFI Performance for tuning. Sean there is a tuning god second to none

hmmm... i have a nismo intank pump in my car at the moment and i'm making 285rwkw pulp and 325rwkw on e85...

injuectors are nismo 555cc

i have an 044 and surge tank setup in my ke70 that i'm stripping and was thinking of moving it to the 33... would this flow enough?

Lots of factors, the lower pressure the pump is pushing against the more it can flow. Bosch and other fuel pump manufacturers have charts of this. Ways to lower fuel pressure, ensure your injectors are large enough so the fuel pressure doesnt need to be raised, run lower boost pressure etc

The nismo pump flows more than the 044. Not sure. The only way to know for sure is to calculate the fuel usage by knowing how many ms your injectors are open for at their peak value in the tune you have. So basically if you can tell me what the largest ms value is in your tune, then I can tell you how many L/min of fuel you are using.

Your engine will consume more E85 than it will 98 so the pump will have to flow nearly double to achieve the same power.

i really wanted first hand opinions not hear say.

seems like theirs a lot of hear say in here :(

As has been said in many of the posts there are a lot of different factors.

If you want first hand opinions get off your butt and go read the dyno threads for 30+ pages of 'first hand opinions' at least 50% of which will have the 044 fuel pump.

We build these cars day in and day out. Some make more than others, some where the customer supplies shit injectors or whatever. Every car is different. You are only EVER going to get estimation when it comes to this sort of stuff. If you plan on making more than 450hp at the wheels on 98, consider a better fuel pump like the Pierburg which flows 6.5L/min

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
