Possibly an intercooler problem as the top of my intake is dead cold after a good thrash, although it is a bigger turbo.

I dont see how it could be a intercooler problem, since the piping
jst after the cooler is cold, yet the piping going into the intake manifold
and the manifold itself is hot. I think it is a radiant heat or hot air exposure
problem thats leading to heat soak of not only the piping but of the
whole area in the engine bay.

Nah il just wrap my whole car in tin foil and squeeze a bit of lemon over
it and let it simmer till medium rare. 8)

its just heat soak from the engine bay, nothing to worry about andy, your engine bay cant be cold like the intercooler.

try touching a normally aspirated intake manifold once its been running for a bit or light thrash .. you will find the temp to be not much different.
you can use the exhaust wrap on the intake manifold side of the piping if you are real worried.

mine(NA 2zz) is stone cold unless I really rape it, then it gets to "can't touch it" temps.

Have seen it done, it looks bad, but seemed to do the job.

Infact, the weirdest one I've seen had all piping from turbo to IC, IC to plenum all heat wrapped, looked ghetto as.
They assured me it helped, I guess it would cut down on heat soak.

How is that ghetto - its called "functional" :D

I did it on my last VR4 - dropped intake temps noticably around 15 degrees, actually gave an improvement you could feel. Plus I rate go faster type stuff in the engine bay above having chrome pipework 8)

I was thinking of cutting up a windshield sun shield (you know, those
large reflective ones) and wraping that around my IC pipe in order to
save money. If those sun shields are designed to reflect radiant heat
away from your car's interior, why cant it work for your IC piping?
My plan was to wrap the pipe with paper towels first
(since paper is a insulator) then wrap with sun shield, thus providing
a multi layer surrounding. Hows that for ghetto? :P

how bout
you rapp it with pink bats then use alloy tape to hold it all togethier taping in a continous sprial

thats wat we used to do with planes and it looks damm cool

with a little thought not everthing pratical needs to look getto

kinda looks liek this

arh well

that looks like rather large chilled water piping
that says acoutical insulation tho...
maybe its steam pipe.

yea haha i realised the pipes arnt that big in your engine bay.....
thats my job to deal with that sort of piping.. thats a nice big solenoid there also.

you can actually buy pipe insulation called armoflex with shiny tin clading.. quite cheap also.

Would it be cheaper than cutting up a sun shield? :P
Where can you get it?

forman insulation i think is the name of one of the places that has it..
price : i just priced a small job and we allowed 360$ for about 10m of piping.. (price included labour).. i cant seem to find the rates.. so yea..
probably similiar pricing to heat wrap.. (but would do better job probably)

Oh ok.
I think il probably give my sun shield idea a go since I have some sun shields around somewhere.
I'l let u guys know how it works out :P
