I need some help.
Im trying to get my car put back together. and so i need someone to explain our fuel system to me...
Im putting in a 454 LSX, shooting for ~600WHP....
I dont really understand how to calculate BC or whatever to figure out what injectors I need... I have 60# motrons and a walbro right now... which I imagine is enough... but is it enough that I can run E85....
I know when i was turbo 60# were good for 600WHP and I kno N/A takes less fuel... or... i thought i knew..
I got a little sidetracked... I dont understand return vs returnless.. not the concept, but why i would choose one over the other...
thanks i appreciate it.
