What can a ls1 stock fuel system handle?
 

discuss...

Why don't you tell us what you have in mind and we discuss why we would or would not recommend certain components in the fuel system otherwise there is a lot of variables

w/37lb injectors(@43.5psi), cammed,bolt on ls6... 425rwhp and had room for more mods.

5 pounds of boost

Thats pretty low pressure, are you running a carb?

at the very least you should install a bigger pump like a walbro, cheap insurance for $120

yeah since my fuel punp is on an occasional scream session ill install a bigger fuel pump
im putting down a bit over 400 on stock fuel and ignition now
just wondering if it can handle a little more

If your going boost I would get a Fuel Pump and some 42 lb injectors @ least.

I have stock LS6 now with only a catback, and planning for 9psi (eventually). Two tuners both recommended at least 60lb injectors. With that, I also got a racetronix fuel pump and hotwire kit for it as well.

i guess ill add another 5 benjamin franklins to the pile. i just hate going back and forth to the tuner paying 400 at a time
anyone recommend any programmers?
