I finally did some datalogging to find out what my fuel problem was. Just to clarify my setup for my 00GT
-42lb injectors
-dual focus pumps
-zone 5 stage 2 fpdm
-full wire upgrade from battery to fpdm to pumps
hitting 100% duty cycle at 5500rpm with around 475rwhp. Fuel pressure drops at 100% duty cycle to around 30-33psi.
I reconnected all my wire connections at the relay to make sure they were good. When I datalogged, my actual volts at the pumps were 11.5v (WOT). First, is that normal? I thought it should be around 12.5-13v. Altenator output was fine.
Next, I heard that there are SVT focus pumps and regular focus pumps. Is that true? I bought the car with the focus pumps in there so I don't know for sure. I heard that ppl were buying the wrong focus pumps. Is there anyway to check to make sure when I drop the tank?
Next, if I do have dual SVT focus pumps, could one be failing? Is there anyway to check if one pump is not working? This question is the important one I would like to know.
Solutions. Can I just add a BAP (KB 40 amp) to get more voltage and get more fuel. I know how to install, just wondering if it would work. Next, I heard that 42lbs of injectors is fine for my setup, but, does anyone think that I need 60lbers? Last, could I just throw in a Ford GT pump? Can one Ford GT pump handle 475rwhp?
Thanks a lot.
