i was reading an article about a swap done to a SC saleen, where they swapped the pump to a ford GT supercar pump, and they said it was good to like 600-700 hp WITHOUT a BAP?

just wondering how accurate this is. been doin alot of research, and right now it seems go sump w/ dual walbro return style, or attemp to find an 03/04 cobra tank and go dual internal with a returnless. and right now the return style seems to be winning the battle, in both budget and performance.

previous/current setup was 42lb ford green tops with a single SVT focus intake pump.
if i can swing it i am gunna grab some 60lb or larger injectors, and work out how i can get the fuel pressure there so they can go "squirt squirt".

i just dont see any reason to keep a returnless system? walbro pumps are about 100-110$ each, a couple of Y-blocks are like 30$ total for quality polished peices. a sump is like 50$, and a FPR is like 70-120$ depending on what you want. add in some lines/fittings for maybe 100$ and your talkin like 500$. last i checked a cobra setup was 600+.

 

the twin supercar gt pumps will support 600-700 hp. im running a single one right now

 

ah, see that makes ALOT more sense. still, return style seems the way to go. i just cant see upgrading when a sumped tank with a conversion to return style seems so much easier and budget oriented (assuming you do a weld in sump and not a whole new tank)

 

i completly agree with you there. it makes no sense in making it over complicated.

 

i am thinking of going with Fore Precision dual fuel pumps with two GT pumps maybe this summer that will fit stock mustang tank. Cost would be 700 bucks.

 

Yea the fore piece is nice, but i think its really a bandaid fix vs the cobra tank, since the GT tanks dont have any sort of baffle, you'd have to be careful not to get too low or any side to side or hard acceleration with lower quantities of fuel could starve the pumps. plus the fore piece also seems way too expensive vs a cobra setup.

i like the weld on sump idea, simple because when using the stock fuel level sending, the sump itself is lower than the tank is empty, so even if i did go E, then there would still be fuel in the pan. PLUS it acts as a baffle itself. seems like the simplest route, and i can save some cash on fuel lines by just converting the old fuel line as the return line to reduce the cost further. that means i can spend more cash on larger lines. i was planning on running a -8AN up to the rails, but i might end up running dual -8's from the sump to dual pumps that merge into a -10 line then run that up to the FPR/rails.

the only thing i have been thinkin about is a bandaid way to patch in the fuel pump relay. at some point i will be converting to a megasquirt setup and that will control the relay but i would like to be able to use the stock ECU for a backup if i absolutely need it.

best thing is, if i feel its necessary, i can run a triple pump system for even MORE fuel lol, siimply by adding an extra pump any Y-blocks. assuming i use external pumps, which is what i plan on just because they're so cheap and outside the tank i can swap them without having to drop/drain the tank.

 

i hear ya it seems like you know what you are doing for me not so much. I never got wot with less than 1/4 anyway. The cobra tank and pumps is much more than what I am thinking of doing but does give buffling though.
