b2200?
OK, new pump installed. Bit of a mission swapping things around, making fittings, and getting it to seal up. But I have swapped my rear pump (044 equiv of unknown history) to the front and installed a new 044 on the rear and a new fuel filter. My pump differential pressure has gone up from 2 bar to 3bar -a good sign. The new rear pump will be better than whatever I had before, and it is still receiving a higher flow of fuel than previous.
My previous pump flow before the FD was 1700/30sec. New flow is 2000/30sec.
Old flow out of FD was 1350/30 sec, new flow 1500/30 sec.
Injector flow is 940/30sec, 820/30 sec was old flow.
So I have picked up a bit of extra fuel, but not huge and still no where near Brian's 1400/30 sec injector flow.
The fuel head is much more stable tho and easier to tune - half a dozen shots and within 3% variance. Not sure I will get it much better. I guess all I can do is try it out.
Any ideas at what flow/HP you need bigger injectors/lines?
Regards
Alan
