E85 Injector And Pump Size?

Discussion in 'Fox 5.0 Mustang Tech' started by montyd, Apr 1, 2014.

  1. I'm doing a 351w swap in my 93 lx. Going to run and on system with a 70mm turbo. I think I need 80lb injectors to run e85 but I'm not positive. Also wondering what size fuel pump to run and what mass air to run or if everyone goes to speed density at this point. Shooting for 600rwhp. Thanks for any help!
  2. 80lb injectors may not be enough for 700hp on E85. you may need something larger, perhaps a 110lb? as for the fuel pump, you should be ok with something designed to feed a gas engine making 700hp.
