So what can the stock fuel pump support?
I know it depends on what type of boost you are running (Turbo/Blower).
And how much maximum PSI you run.
I'm just trying to get an idea of where my cutoff point is for my set-up.
I don't think I'll run any more than 10 psi when I go to the track, but I still want to be safe at that level of boost.

 

350 rwhp.

 

You can't go by boost levels. Because a 6.0L would probably make more power than a 4.8L at the same boost level.

I see you have 44lb'ers so you'll be good to go there.

 

Don't risk it. Get a fuel pump and play it safe.

 

i always thought it was over 400rwhp. i have sprayed a 150shot on a 6.0 and was ok but when i tried the 175shot the fp started to drop up top.

 

So basically I'm so borderline right now it would be a risk for my current set-up? I have heard things pro and con for the in-line pump, what opinions do you guys have on the subject of in tank or in line pumps?
Thanks for the feedback.

i had an inline pump on my last truck and it seems to work great. before i got rid of the truck i was up to 10psi and a 100shot on a 6.0. they are cheap too.

 

Get the fuel pump, I was going lean 2 8psi
