Nitrous Feed Line Size

[FAT460]

Hey Guys...

Has anyone documented the difference between running say a dash 4 feed line against a dash 6 feed line on the same setup???? What is the effect????

I think it would depend on how much nitrous you're wanting to push. If you're running something like a 50 or 100 shot, then Probably not all that much difference. 950 PSI makes it through the feed line pretty fast, and then it's just dumbed down by what sized nitrous jet you put in. It would probably make a big difference if you're lookin to running a few hundred hp.

General rule of thumb is that a -4 feed line is good for your average "street" shot up to 150 HP. It wont make much difference below 150 HP switching to a -6 line. From 150HP to 200 HP shots its generally a marginal gain switching from a -4 to a -6 feed line.

I have seen guys pick up some substantial HP switching to a -6 line at at the 200 HP and above mark. Before that is really a big issue, you need to switch out the -3 nozzle line for -4 though if you use -3 and make sure your solenoids are of the bigger nature as well, as most of the basic noids wont flow over 175 HP worth of nitrous anyway.
