its theoretically if pushed to the absolute limit by parts swapping between the varients to get a setup that will pump as much fuel as possable. We discussed this a lot in the dieso room at ALTC and I think from memory we came up with a max fuel of nearly 450ml per pot per 1000 deliveries. I have no idea how to squeeze that much air into the chambers to effectively burn that much fuel very very rough guestimations worked it out at each pot would need nearly 20l of air inside it prior to the upstroke on compression, Thats a very very big and very very angry turbocharger or supercharger.
on a stock pump its nearer the 250ml/1000 mark but in reality you almost never go past half maybe 3/4 of that even on a worked up turbod version. the stock version has the absolute max set as something like 125ml and the governor limits it to about 95-100ml to the 1000.
you can check you pump deliveries without pulling it down and Ive been known to do it with a specially distorted injector pipe on each pot as part of a major service if low power is complained about even tho every other possable source has been investigated.
ive also been known to install injectors upside down to do a spray pattern test.
