Oh.

Then, never mind

Sounds like a very efficient set-up if that's at full boost.

Thankfully I've never had any heating issues and I live in South Florida. Oil cooler and that's it.

you could do what the EVO guys have, hook up some intercooler sprayers, that should help bring down temps a bit, especially at speed

I often wonder if our intakes were Plastic (since metal acts as a bad heat soak) how much that would effect the IAT's.? Referring to the entire tube from the throttle body passing through the engine area to the intercooler.. It is possible because most cars now have plastic intake runners just for the heat soak..

The problem I think might be plastic can expand and with forced induction you do not want that.
If you want to counter any heat soak you can do thermal coating, intake pipe wrapping, or even do the gold wrapping stuff.

Yea I didn't think about it expanding but do you really think it would at a low to medium boost? Considering the plastic would have a decent thickness too. I would think a heat wrap would hold the heat in considering isn't that what its made to do?

The expanding part wouldn't be that big of a deal..

Schedule 40 PVC (the white, cheap stuff) @ 3 inches is rated @ 158 PSI operating pressure...

So if you had some piping made that was maybe half that thickness, you'd theoretically be in the 78-80 PSI range for operating pressure. That's @ 73 degrees f.

PVC wouldn't be a good choice for this application, it can't really handle the temps for any length of time, but I just wanted to use it as an example of good thermoplastics' pressure handling characteristics.

At the very least, plastic cold pipes could be used, but the tooling to manufacture them would likely be prohibitively expensive. Same goes for a composite design.
