Alright looks like I will be picking up the injectors we'll see how the stock pump keeps up when we get the boost going. Thanks for the help. And yes it will most likely be under 10 psi most of its life. I will do it in stages and upgrade when I need to.

 

which injectors are you going with?

 

P# 30507-8 50lb from an ls7, the same ones I was asking about, I'm still not sure if they plug into the harness but they work in the fuel rail.

 

Could always get a set of stock e85 flex fuel injectors for your truck.
I think they are 54lbs. Don't quote me. LoL
Btw. Your kit will be ready next week.

 

I have been trying but can't find anything around here I have also been looking for an e85 pump but can't find one of those either.
I CANT WAIT! Lol great to hear

 

Come on man!!!! This is why I made this thread

Thank you!
So does anyone know what stock e85 injectors are for Lb/hr? I see that you are maxed out at 8psi I would like to make sure my 50's will be big enough

 

I've got 42# on my brain for some factory Chevy application. I thought flex fuel inj's were 42#. Or are the 8.1's? Somebody on here knows.

But maybe this will help.

I guessed i was approaching the limit of the flex injectors and was already thinking about doing more boost so I upgraded to 60s. At 8 psi my tuner said I had enough fuel pump and my injectors were keeping up.

I don't know of anyone that has done more than 8 psi on stock flex fuel pump but I know I did 8 all day long w mine.

 

Ok, and how much power or boost are your 60lb injectors supposed to be able to keep up with?
