PVC/ ABS snorkle....anyone concerned about the 175 degree F melting point of PVC

No concern....If the air running through it doesn't cool it down, nothing will. Might be a slight heat soak issue when you shut it off, but I doubt it unless its right on top of your turbo 
Thanks. I was thinking...just for insurance to wrap the PVC/ ABS section under the hood with insulation, or use another material under the hood and then transfer into PVC/ ABS (90* elbow) as it goes through the body.No concern....If the air running through it doesn't cool it down, nothing will.

since you are thinking of doing PVC or ABS DWV pipe, you could stay in the same class of pipe and do cast iron DWV pipe under the hood. the stainless no hub bands would look pimpin yo!

I used a piece to run from the airbox to the intake and smooth out the flow, after a bit of time the clamps holding it together would deform the plastic from the tension around the outside.

i would be more concerned with UV degradation of the PVC pipe outside the engine compartment due to exposure to sunlight. After a while it gets pretty brittle.

don't use PVC. The gases given off when heated is the same chemical used in the showers of Auschwitz.

Yes, use ABS. PVC will also get brittle as mentioned above. When I was young we had this big potato gun. The first one was made from pvc and eventually shattered. The ABS version never broke.

http://en.wikipedia.org/wiki/Pvc#Health_and_safety can be a start for sources, although a readthrough doesn't directly mention releases in gas form. I will have to find that one later. There was a big discussion on it on revscene.net a few years ago.

theres an additional drawback to ABS plastic, after poor temp resistance, and toxic offgassing.
ABS has very low oil resistance. It softens in the presence of hydrocarbons. PS fluid, motor oil and ATF will eat it.
PVC resists oil fairly well, but doesnt belong under the hood.
It also resists sunlight fairly well because it has UV inhibitors added.

I've been running an abs snorkel on my daily driver for more than 6 months and haven't had a problem. I know thats not the longest amount of time but I drive quite a bit and I ran the abs under the hood and into the back of the the stock airbox and haven't had any issues with it at all.
