Stock fuel rails

[bottlefed97]

Does anyone know how much horsepower stock 4.6L fuel rails can handle?

I am going with 60# injectors and a 40 amp boost-a-pump. I expect around 550 to the ground, so i'm wondering if I need to upgrade my rails as well. Thanks!

im not sure man. im sure some high volume fuel rails wouldnt hurt @ all though. might as well spend the $ to make sure since uve spent that much so far!

all the misfits guys I know of run stock rails and a few other ppl with larger injectors run stock rails. Ill ask a few people tomorrow and see if i can get an answer for you.

if you decide to get rails. get the fore's they are bad ass. i have stock rails on my car but i have a returnless system. did 500 rwhp and 570rwtrq on a mustang dyno. dual cobra pumps boost a pump and 60#ers

I got the MMR ones just for insurance. Good quality pieces, bolt on brackets not the crappy clamp ons.

pretty sure they are good for right around 600whp, but for as inexpensive as they are i'd go aftermarket.

I ran stock rails at 500 rwhp, injectors were holdin me back but not the rails.
