Default PVC intake pipeing

Ive seen it before, and I know it works. I really like the price of pvc pipe too.. like 3 dollars for 3 feet. 85 cents for a 90 degree bend. Has anyone elese used PVC pipe? Id really like a few pictures if so.

He said intake piping... not IC piping. Intake it'll work fine for.

I have a 90 bend in my intake tract on my civic. Works fine and fit exactly what I needed for cheap.

The heat degrades the PVC and the fumes does something bad. It's been done many times and it works but PVC isn't rated for the heat of an engine bay.

I think it releases toxic chlorine gas when heated.

As opposed to non-toxic chlorine gas?

I used it on Beast (a 12" straight section of 2" PVC) when she was JRSC'd and I now use it on my wife's blue Miata with a 45 degree bend (JRSC'd). No problems so far...

I wouldn't hesitate to use it on the coldside IC pipes if I were looking to save money everywhere. Hotside, not so much.

BOV gas is different than fresh air intake gas (if that is what you are trying to say). Not sure if you are making a point about engine heat or just giving some FWIW <G>.

I have been using ABS pipe for all my intercooler piping except for a nice mandrel bent steel pipe coming right off the turbo. I planned on switching to metal piping originally but this worked so well i just never got around to it. It has worked fine for 5 years. I did try ABS with a silicon coupler right off the turbo and it kept melting and warping. For the coldside though it works fine. YMMV on the hotside.

Regards

I used the black pvc piping(flows better because how it connects) for my new intercooler setup, right off of the turbo it is steel, all the way down to past the undertrey, then it goes to pvc.

I really dont think it should present a problem, but if it does ill sure as hell let yall know.

Grey PVC = electrical. No PVC is rated for heat that I know of.

ABS handles more heat then PVC does. I had my first diy turbo ran in PVC. It lasted about 2 weeks (right off the turbo), the cold side from the IC to TB was fine. No reason PVC or ABS couldn't be used for the intake pipe on an NA car.

If someone would come out with a PVC like product that could handle heat it would be a winner. Pressure is no problem - schedule 40 is rated for something like 200psi- connecting and cutting pipes is a piece of cake, and the cost would be affordable. User friendly and eliminate all those clamps - it'd be great. Too bad it doesn't exist yet.

Make your intake! If it fails, melts, bends, falls off you aren't out much. If it works for years you're golden.
