How High With A -4an Supply Line?

What hp level is a -4an line capable of? Im running a nx dp setup pilled at 250hp right now which seems to be doing ok. I didnt buy a kit,I just collect parts and put a system together,so i dont know if the kit ive got is supposed to have a 6an line or not.The pills that I got with the nozzles where up to 500hp.:death:

Much of that is dependant on the pressure you run. I got right around 300 rwhp thru a -4 line. But I had the pressure jacked up to around 1150 psi.
It also depends on the line manufacturer and the fittings you use and wether they are 90 degree bend etc etc.

But right around 275-300 usually.

If you want to step to a -6 line let me know and Ill get you good price on one.
