how hot do...
external wastegates get?
or more to the point, the bit where the vac hoses go?
as i am thinking about using them pnumatic push fittings on mine, and they being plastic might melt lol
i will of course use some of that heatproof sleeve stuff

Looking at how manufacturers do it is a good idea.. I'd try and route stuff as far away from the hot parts as possible - putting that sleeving stuff over should be adequate. Worth checking every now and again though for blistering (don't want a nasty overboost whilst you're flat out).

looking at that, i imagine that the bottom one of the 2 will get well over 200 deg. C due to the proximity to the exhaust turbine housing (although it's hard to see how close it is from just 1 angle). the top one should not be a problem, although both depend on airflow through the bay

Thing is, braided hoses act like heatsinks so aren't really what you want. Audi use a solid metal pipe about 6" long off of their external wastegates before going to a rubber/something hose. That's a sign.

are they the type that i linked jonnybravo to on a different thread? if so, they're the nuts. they look very tidy and IMO are probably the best way to deal with pressure/vacuum pipes in an engine bay

certainly are mate, i had seen them before, but not all the fittings in the same place - cheers

a shield between the 2 will probably do the job - it's the air gap that's the insulator.
no way to know really dan unless you try it. manufacturers instrument the entire engine bay to find out things like this and then tow a trailer up a hill in a hot climate to put maximum load on the engine to be sure - and that's after months of thermal simulation work on super computers. you will just have to trial and error it and see if it melts
