Its a Tomei 280lph pump, have the same in my car, its 1 step down from a Bosch 044, its a £300 pump lol the car it came out of must have been pushing a nice bit of power to need an upgrade like that on it, I got mine as I was going for 600bhp.



Stock pump left, Walbro 255 middle, Tomei 280 on the right

cheers mitch, you are a font of FC related knowledge!! yeah the car was running 720 primaries and 800 secondaries and t04r, with Vcon pro 2 silver, the rotary tuner in japan stated 450ps, but that might have been a bit optimistic.
Anyways removed it as i am putting in a bosch 044, plus my uk fc was in need of an upgrade

cheers again

Thats probably about right also look into upgrading to a parallel fuel setup if you are going big numbers, plus, make sure the fuel filter is new!

with 720\'s and 800\'s you can probably still get away with a serial fuel setup - the stock lines and fuel rails are quite \'flowy\' (is that a word? )
 
But as M1tch says, if you want to push much more than that a parallel flow setup is the way to go, and  you may want to think about beefing up the hard lines after 500 horses, as they can begin to be the limiting factor.
 
450PS - not likely !  Even with the injectors maxed to 100%, those sizes would only net you 430 horses at the fly, a more likely figure is high 300\'s (390 ish).
 
I am planning on 400 bhp with 800\'s all round, with a small increase in fuel pressure for some additional headroom
