PVC Pipe for Free Flow Exhaust Coupling
I just took out my baffle and went straight from the watebox to the exhaust pipe using a 2 inch x 6 inch long schedule 40 PVC pipe as a coupling between the two hoses. Will this melt or will it be ok. I ran the engine on the hose for 30 minute and pvc just felt a bit warm. I also spinned the waterbox so that the neck was in line with the exhaust pipe to get a straight run, the position on the neck shouldnt matter. correct??

really?... have you put it in the water yet? If it were me, I would turn that waterbox back where it belongs.

I wouldnt think that the pvc would get too hot as the exhaust is watercooled. but...it might?? I would run it and see...
I dont understand what you are saying when you say that you rotated the waterbox. pics would be nice. how do you rotate it and get a good seal?

what is so wrong with using a steel pipe?????? you KNOW it wont melt.
and i feel that the waterbox should be in the correct position instead of turned.

24th edition of Machinery's Handbook says PVC is rated at 180į F without pressure.
My experience is that it will handle pretty high temps.
However, my opinion is that the off-white color would not compliment the cool blue hoses in the back of my ski that came with the R & D cooling kit...

The 40 grade pvc may work ok to start, it is thick wall pipe. However, the heat may cause the pvc to become brittle and even crack.
If it survives the heat o.k then at least replace it a few times a year or every season.
