Reliable 450whp fuel setup
#27
for my 450hp set up im using a dual walbro all four 1600cc injectors. upgraded fuel rail and lines and fuel pressure regulator. using e85 of course. only 15psi. and i have yet to have a problem with my walbro or any issues with this fuel setup. soon to be 25psi

i'm running an FD motor with to4s .86 turbo at 15psi, an estimated 400hp (street tuned)
walburo 255, earls fuel filter (35micron), marren FPD, 720 side feed primary, 1680 top feed secondaries and areomotive rising rate 1:1 FPR all -6 SS fuel line.
at a 65% injector duty im using about 190 LPH, the walburo has a rated 255LPH. but when you factor in the pressure:volume loss (38psi base pressure), my fuel pressure falls off at 7300rpm.
i'm going to upgrade to a parallel system. my question is that if i'm using This Aeromotived FPR do both fuel pumps have to be the same, or could i put a stock TII pump for the primaries and the Walburo for the secondaries?

I disagree. -6 and standard 3/8 fuel line are identical as far as ID. the only real difference is the outer steel braiding. My car had an identical setup the OP was describing with -6 (stock sized) lines an i had no problem whatsoever. I only went to SS lines so i could connect everything with AN fittings to be sure i wouldnt have any leaks
however, the age factor is something to think about. not necessarily for dirt and grime but for old fuel turning into varnish and the hoses cracking and leaking.

2 fuel pump hangers built into 1 duel hanger. bt i'm not sure how i'm going to feed the wires through. i'll have to try damn hard to find some insulated terminals or bolts.

nobody answered my previous question though. on a parallel fuel system do both pumps have to have the same output? I still have the stock TII pump, an FD pump and my current walbro, so if the answer is no, i saves me having to buy another pump

I'm holding a reliable 400+ hp. The motor has only cost me 4500$ the fuel system and engine management $2800, kinda helps when you do all the work yourself and fabricate what you can.
