AEB fuel pump: how much can it handle?
AEB fuel pump: how much can it handle?
I am running a custom setup on my AEB.
To get A/F in line, I am currently running 70 psi (still a tad lean).
How much pressure can the stock pump handle, adding the boost (say 22 psi)?

Just back from last 'dial in' run.
At 70 psi, still showing Long Term Fuel Trim of 12%.
Also overboosting.
Had misfires passed 15 psi (NGK BKR7E gapped at 0.028).
Put in MBC in parallel to N75. Dialed in at 20 psi.
Reduced gap down to 0.024.
Running fine now.
Will log MAF etc. tomorrow to see what she flows. Hoping for 200+ g/sec.
Also see how LTFT settles (will live with 10% or thereabouts).
On the other AEB, running 76mm MAF (pegged the 70mm, K04 based custom turbo with big billet wheel), I won't get by with fuel pressure alone on current injectors. Will try 440cc (on the way) and dial it in.
Hope to flow 280 g/sec when dialed in.
