poly line vs. steel braided

[afterhours]

what are everybodies thoughts on this.....i was worried about the poly line getting damaged due to the engine heat, when i am fogging the box??

Your concerns are valid. All poly lines are not made the same. Some of them can withstand engine heat but unfortunately most Nitrous kit suppliers use poly lines that cannot. If you use stainless steel lines make sure is it wrapped. The stainless can rub holes in electrical wiring with can cause shorts or fires.

Go to this website http://www.mcmaster.com do a search for Wire Sleeving. Once there look at Convoluted and Spiral wraps if you go stainless. Look at the operating temps on them both. Some of the wire wraps operate up from 500 - 999*F

the heat cycles of engine heat/nitrous can turn the line ultra brittle... stainless/teflon line is suited to this use far better than any poly..

+1 - if you take your bike apart much you'll soon tire of messing with polyline. It's fine at first to get you rolling but once heat cycles harden it like Bogus said, and once you've taken it apart and put it back together a few time you'll grow to hate it. I run steel braided and it's much easier to deal with.

Poly lines are fine as long as they are inside the Airbox.

I am looking all over the place but so far have not found any poly line rated for -150 to 200+ F @ 100psi (realistic operating temps) if you come across any, I would like the white sheet on it.. thx..

Did you look for Polyethylene or Polypropylene?

I use a black industrial poly line inside my airbox to route the spray to the V-stack spraybar. It works fine there. But I use ss/teflon line everywhere else...as Mr. Bogus said.

I ran all braided stainless but had the guy at the shop that made my lines give me a strip of protec ballistic nylon wrap to cover it its rated to lik 800 degrees so far so good.

Both have their ups and downs. Poly line actually distibutes better than braided lines. It all comes down to installation. Take your time and install it correctly and route it correctly and you will never have a issue with it. Braided line has more durability but can collaspe inside the braid and you will never know it. Its harder to fine faults with it if a problem occurs. Always test all braided lines anytime you disconnect them for good clean flow.
