    8-AN feed 6-AN return. If you are running Eth or Meth from a tank 10-AN feed and 8-AN return. If you are going to run solid hardpipe stainless lines 1/2" ID supply 3/8" ID return.

    Don't know about the nology wires. I've seen a few subi's and evo's with them but have never used them, tuned a vehicle them, etc. In for the info on the nology.

    One -6AN feed won't work with much more than BPU. I have run two -6AN lines into one -10 and two -6AN lines into one -8AN line and two -6AN line from the tank to the fuel rails. The last option is my choice for overall simplicity and ease of installation. One -6AN line return is good. The entire system (less the cost of fuel pumps) can be done for about $500, including AFPR. Just my 1.5 cents worth.

    i take it that if you run 2 -6 an lines, you don't need a loop--but you will need 2 FPR's and 2 filters?

    -6 can go very far, we have a couple evos running the stock hardline making 600 wheel on ethanol.

    My car was on -6 feed slit into both rails then out of both rails into a fpr and then used the stock return.

    How much power are you going for? -8 feed with- 6 return is about the farthest you will need to go.

    -Ricer Evo 8: 8.75 @ 166 Best MPH of 167. Quickest 4G63 Powered Evo in The US!!!
    -Chris Cessna's Stock short block Evo 8: 9.76@150 Worlds Fastest Stock Motor Evo 8 and First Stock Block In The 9's!
    -Shawna's DD Evo 8: 9.97@143.88 Best MPH of 145 Full leather interior, A/C, navigation, stock brakes, cruisin 9's in style
    -Cory's Stock 7 bolt talon: 10.3@136 No crank walk here...
    -STM Stock turbo/motor Stealth RT: 10.95@127 Worlds Quyickest/Fastest and most powerful Stock turbo/ motor 3S
    -James STM built Pump gas Evo8 stock motor: 10.2@137 Stock long block, and only on pump gas!
    -Mike Faggiano Evo3 16g stock motor 1g 11.0@124 just a 16g knockin on 10's door.
    And the list goes on...

    peak power from this setup (if tuned on race gas) would probably be around 650. i plan on running pure pump; but i want to have the capability there. for argument's sake, let's say i wanted 1000hp on e85. how big would i need?

    p.s.

    austin, you never got back to me on those fuel rails. i'm needing a set.

    Thanks for the reminder, ya -8 feed with -6 return would be plenty, we are running that on our shop evo with 2 in tank walbros, and almost maxxed them out on e-98 (which uses more than e-85) at just under 800 awhp on a mustang dyno. If 650 is about your max then you will probably be fine with -6, but if you want the extra room, go -8 and you wont have to ever change it.
