Anybody know how high the temp gets in the pipe work of a fmic before and after the intercooler. Cheers

 

Also has anybody Made carbon fibre intercooler piping for an impreza before?

 

Wrap it and you shouldn't have a heat problem, and i don't mean carbon wrap lolol

 

I know I can wrap it but I was gonna try making pure carbon pipes the only alloy being the end inch so it doesn't crack the carbon when you clamp it down.

 

As above heat wrap and turbo blanket and you should be OK

Something like we have:

How are you gonna join the carbon to the alloy buddy.

 

I guess it does the job but that heat wrap is normally used to keep heat in! Logically, I would have thought reflective tape would be preferable?

But you want to keep the heat inside the pipe so that it doesnt heat up the engine bay.

 

With a bonding agent. Im gonna take the ends of the piping (3inch) and bond it from the tip down so it will from the outside be seamless carbon and the inside ends with be lined with 3 inches of alloy so it won't crack if you get giddy with the clips.

 

before intercooler, anything between 130deg c up to 200deg c depending how hard the turbo is working, 150c is a good average but these are peaks and temps can drop by half in a split second once off boost. Post intercooler, should be within a few degrees of ambient.

Great. Cheers mate. The resin works to 180 deg c so il stick to post intercooler for now.

 

Exactly correct. If the turbo is stretched beyond its efficiency range you wiill get 180-200 deg.C. at the compressor outlet.
There is no point heat wrapping the pipe from the compressor to the intercooler. All that heat wrapping this pipe does is ensure that the air temperature entering the intercooler is higher than it needs to be. The temperature in the engine bay and in the inner wing ( ie. the pipe route from the compressor to the FMIC core inlet ) is below the compressed air charge temperature in that section so there is cooling to be had naturally without a heat barrier ie. exhaust wrap.
Also note that black is an abosrber of heat so anything wrapped in black will absorb temperature from the surrounding area. On the cold feed to the throttle body you would be better to heat wrap with exhaust wrap, buff colour with a silver reflective heat sleeve over the top so you do not absorb engine bay temperature on the cold side.

 

See Harvey's post!

If he does job,in my view yes,if doesn't job its not fitted/wrapped and still we are not running any kind of cold air feed

Underbonnet temp are OK

"Hear wrap" is a thermal barrier. It keeps cold in or heat in. It keeps heat our just as it keepscold out. Don't thonk of itas anything else but a barrier to heat.
