RC K9 Posted July 11, 2012 Report Share Posted July 11, 2012 HAs anyone here made their own intake pip using PVC? More specifically, for a turbo application? If so, did you have anuy issues with it? From what I have read, PVC melts at 400f, so for most of the pipe I am not concerned about the under hood temps, but with the end feeding into the compressor housing being so close to the turbine housing and exhaust manifold, I don't know if it will get that hot or no...

I used pvc and the silicon clamps from jegs on my old 5.0, was great and the price was a plus. If you're concerned, you could always run regular piping away from the compressor and then use pvc. Why the red green fab though? Quote Link to comment Share on other sites More sharing options...

Nickey4271647545519 Posted July 11, 2012 Report Share Posted July 11, 2012 Haha... I wonder how much boost you could get pvc to hold anyways... PVC and any amount of air pressure is an accident waiting to happen. Quote Link to comment Share on other sites More sharing options...
RC K9 Posted July 11, 2012 Author Report Share Posted July 11, 2012 Haha... I wonder how much boost you could get pvc to hold anyways... I am not talking about using it post turbo, I am talking pre turbo. It wouldn't see boost. My FMIC piping is all aluminum. http://i1038.photobucket.com/albums/a461/RyanCorlew/DSM/IMAG0772.jpg http://i1038.photobucket.com/albums/a461/RyanCorlew/DSM/IMAG0767.jpg http://i1038.photobucket.com/albums/a461/RyanCorlew/DSM/IMAG0771.jpg Quote Link to comment Share on other sites More sharing options...
MattKatz Posted July 11, 2012 Report Share Posted July 11, 2012 PVC and any amount of air pressure is an accident waiting to happen. Are you serious...lol. Do you eve realize what kind of pressure they are rated for? More than most turbos on a car(gas) will make. And that's just schedule 40. This is hilarious.

When PVC fails (With gas/air) it turns to shrapnel and is extremely violent. If you'd like to discuss further feel free to PM me Quote Link to comment Share on other sites More sharing options...

If you'd like to discuss further feel free to PM me Serious question, how is liquid pressure different than air/gas pressure? Do not tell me about how liquids are non-compressible etc. etc. - think about what pressure means. If you don't exceed (or even approach) the rating, then you're fine.

MattKatz Posted July 11, 2012 Report Share Posted July 11, 2012 It is rated for liquid, point is it would work and I've seen it done many times for cheap intake. Do I like it, no...would it work...yes. Quote Link to comment Share on other sites More sharing options...

Liquid takes the force of the pressure with it, where as all the pressure in an air setup is transmitted through the pipe. The plastics designed for air/gas use (ABS/HDPE) will form pinhole leaks rather than turning to shrapnel when a failure occurs. Quote Link to comment Share on other sites More sharing options...
Smokey Posted July 11, 2012 Report Share Posted July 11, 2012 I did it when I had a DSM and was cheap and in college. :fa: For pre-turbo as an intake as you described I had no issues. I wouldn't want to be using it for a pressure pipe though. 1 Quote Link to comment Share on other sites More sharing options...

TurboNova Posted July 11, 2012 Report Share Posted July 11, 2012 just get some mild mandrel bends and make one, or out of a dryer vent and have someone make one for you. Quote Link to comment Share on other sites More sharing options...
RC K9 Posted July 11, 2012 Author Report Share Posted July 11, 2012 Mandrel bends are more expensive than PVC. DSMer ='s Cheap. The intake is already built and installed as of yesterday, just trying to figure out how it will hold up. Quote Link to comment Share on other sites More sharing options...
justinwebb Posted July 11, 2012 Report Share Posted July 11, 2012 I used it for my Oldsmobile cutlass ciera as a joke lol, had it on the car for years. Never melted or anything Quote Link to comment Share on other sites More sharing options...

351mach11647545510 Posted July 11, 2012 Report Share Posted July 11, 2012 on a serious note, that would be something that would be kind of cool/expected on a true rat rod Quote Link to comment Share on other sites More sharing options...
Benner Posted July 11, 2012 Report Share Posted July 11, 2012 this is something Grand prix guys have been doing on the supercharged 3800's for a while. I did it as well with doulble walled 4 inch piping. It's a $20 intake that outflows anything on the market. Quote Link to comment Share on other sites More sharing options...

Miller Posted July 11, 2012 Report Share Posted July 11, 2012 I bought my old type s bov off of a guy who ran pvc on his cold side @ 8 pounds. He sold me the bov because the engine let go, piping looked fine If it can do that why not use it for a cai? Quote Link to comment Share on other sites More sharing options...
