I've noticed that there are no vacuum lines routed to the chargepipe on turbo setups eg( the line from the valve cover to the intake arm on NA setups). i've also wondered where the temperature sensor that normally is placed on the intake arm goes on a turbo setup. i've looked at many setups on this board and can't find what happened to that sensor. Anyone know what i am talking about?

People let the IAT hang in the engine bay or tap them into the mani. The Type-r mani already has it on there.

 

on the valve cover they put a little air filter looking thing, look at the pics of turbo set ups and youll see a little air filter lookin thing instead of a hose to the intake arm

 

So does the LS manifold too right? but is it a good idea to just let it hang...Why is it not a good idea to mount it into the chargepipe? Because boost can still leak i am assuming? Well...what about that vaccuum line out of the valve cover.....where does that go...I see some people just get breathers for the valvecover...but do some people route that to somewhere else?
