2.5" Flexable PVC intake pipe

[Rock2610d]

I did a search but came up with 1000s of posts on the Pcv valve. Sch 40 is good to 92 psi at 140 degrees. Anyone ever tried it? Comments good or bad. It comes in blk or white.

i have not tried it. i would worry that under-hood temps could exceed 140 F and melt or warp that pipe.

The standard "Schedule" rating of PCV pipe only applies to solid pipe. Even though the flexible hose is labeled "Sch. 40" it has much lower ratings. Your typical 2.5" hose has a working pressure of 50psi and burst pressure of 125psi at 68*. However, as the temperature increases, the hose strength decreases significantly. At 140* the working/burst pressure is only 22% of the original rating, which gives you 11psi/27.5psi of working/burst pressure. In the engine bay of our cars, reaching 140* is not difficult to reach. So I would highly recommend against it.

I have used it and it has not failed me yet.

The risk too high for the low reward (little bit more flow). You don't want it to melt or burst and have your turbo suck it all in. Either go stock or use a more typical aftermarket type piece. I use the extremepsi intake, think it was about 80 bucks. Not a bad piece at all, pretty decent.

Sounds like a disaster waiting to happen. I used it once on a n/a motor. However that was a lot easier to find and a lot cheaper to replace than these motors, so I really wasn't concerned. Not to mention I was 16 and a cheap a$$. Do some trial and error. Cut a foot length and place it under the hood somewhere close to the stock intake, give it a few days to a week and check to see if it has distorted at all. If not, it's your car use your best judgement. Good luck. Let us know how it works out for you.
