Default I need some help.

Alright guys, 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.

NO the single pump is only good to 600rwhp NA and E85 requires 33% more fuel delivery. So about 400-450rwhp on E85. You will need to up the pump to duals or something else before you can convert to E85. give me a call I can help you with your setup.

You will have to significantly increase your fuel system capabilities to run your car on E85.

Give me a call & I'll be gald to explain the fuel system options to you.
