View Full Version : bosch 044 pump

so, the 044 has flow rates of 300lph at 72 psi as compared to the walbro's 244 at 43 psi

the 044 can be found as low as 200 bucks and the walbro half that but at 72 psi it IS half that

injectors are tested at 43-45 psi but we all know the flow much better at higher pressures. the walbro pump at 72 psi flows something like 145 lph....

also on certain setups under boost you do get to 70+ fuel pressure.

i want to hear all imput on this pump from you guys from theorys and calculations to experience with this pump and the walbro

It flows more at higher pressures than both the supra and walbro, and it is more reliable than the latter as well. I intend to run a base pressure of at least 53-55psi and peaking around 20-22psi of boost.

lol exactly my plan, whats your settup again?

My setup isn't much. Mostly stock stuff with a td06. Overall goal for my project from the start was to make as much power on the stock ecu, reliably, as I could and do it cheaply. But fueling isn't of those areas I wanted to cheap out on.

Denso fuel pumps are the shit and don't worry about it bumping the pressure up, ATS tunes at a base pressure of 50psi.

i c, still look at the specs for everything if you plan on a lot of hp the 044 can handle 700+hp the walbro can't that is alone not dual pumps. i know that denso units are really good but this is the best pump to go with period.
