Max size injector on stock rails and lines but upgrade dual pumps?

[nasty_ss]

just wondering what stock rails and lines could handle as far as injector goes. or maybe max hp rating. planning on running 340 with a 255 secondary and want to use 80lb injectors on a pt88 turbo setup. not sure if i can run it like this or if it just needs rails or larger fuel feed line. car is 99 fbody

I would also like to know.

The stock regulator on the tank will be overloaded before the rails come into the picture. The 340 by itself is known to do this

so replace lines, regulator and rails all at once then?

Skinnies is/has run 855rwhp on E85 on stock rails. Thats the most Ive heard of.

could i get away with 60lb mototron injectors if i'm only shooting for 700-800rwhp?

If this is your goal I doubt 60's will do the job unless you're running high fuel pressure. Honestly, if you're at that point why are you messing with stock rails? Get an aftermarket set and do your fuel system right. What exactly is the build?
