Should I upgrade my fuel pump?

Hey guys wanted to get your opinion on whether I can get away with a stock fuel pump or if I should just go ahead and upgrade while I'm at it. I know this is the FI section and I'm NA but most of the fuel pump questions I've seen on this section of the forum. So I wanted to get your guys opinion on which direction I should go. I'm shooting for 650 hp at the flywheel not at the rear and I'm wondering if the stock pump could handle it or if I should upgrade? If I should upgrade what are some of the recommendation as far as alternatives.

Thanks in advance for any input I really appreciate it.

Boost a pump or even better is the ZL1 pump.

^^ I concur! The ZL1 pump is cheap (relative to what you've already done) and you already have the tank out. I'm surprised your not making a custom fuel cell... I should probably keep my mouth shut before you get any more ideas...

ZL1 fuel pump and ADM FPCM. I hold steady pressure a 600+ to the ground so it will be plenty for you.

Def. go with the ZL1. You could use your stock pump and go with a BAP, but then you'll be shortening the lifespan of the stock pump, so +1 for the ZL1.

It also goes to say that if you ever want more power, upwards north of 650+ at the wheel, you'll be good to go.

Way to go lol, now he's going to want to make a pretty perfectly welded and fully polished fuel cell

He is naturally aspirated. Takes less pump to feed a na motor then a forced induction motor. But still might as well throw in a zl1 pump for 230 bucks

You upgade everything when you add a supercharger,go to 1/2 diameter line as well.You don`t want to lean your engine out ,that can end up being expensive.

When it comes to modification. There will always be more. By the time you buy a BAP and ZL1 with ADM Controller it would have been worthwhile just to buy a LPE twin pump. That what I suggest to my customers. The ZL1 pump just doesn't give enough of a window once you start going a little heavier into the motor.

I'd go with the ZL1 pump, I have had terrible luck with LPE stuff.

No need to change anything if in fact you want to stay around 650 crank hp. That comes out to about 550rwhp which is doable depending on if you are stick or auto.

Before the twins went in I dyno'd the camaro and it made 464rwhp though the auto without any problems.

If and when you want to take the next step go with a Squash twin pump setup. That will let you go up to 1300hp.



Don't fix it if it ain't broke!

Go with a squash setup when you are ready for a fuel system.
Just installed mine. Twin dw300 pumps wit ptfe lines and aeromotive rails.
Thing performs flawlessly.
