what do you wrap your intercooler pipes with? do you use exhaust wrap? thanks for any advice

 

I chose to use dei cool tape and their turbo jacket kit to cover that and exhaust wrap for the decat downpipe.

It's available from most subaru specialists i used flat4.

 

I used some heat insulating foil wrap. It's basically super sticky on one side, then a sandwich layer of fibreglass weave with reflective aluminium foil on the outer. Works really well on my FMIC pipes. I did my usual 15 mile commute this morning and the charge temp at the throttle body never got higher than -2 degrees C! I have the turbo outlet pipe taped, all the way down to the first joint under the air filter. From there to the FMIC inlet it's bare. From FMIC outlet to throttle body is all taped.

 

Same as the dei tape then.

anyone got any pics of this sticky DEI stuff

i used heat stuff but not the sticky stuff and fixed it with small cable ties, does the job but looks a bit messy

 

by the way

HUX - there's the pics of the murray clips
think it was you who asked,

 

If you hang on a week or two i'll have the stuff on my car, im hoping a 15ft reel will be enough.

Those murray clips look interesting, cba to go all the way to plymouth for them anyway so i'll wait to see what the ones flat4 supply will be like first.

The dei stuff is called either cool tape or heat barrier tape.

 

used exhaust wrap did the job

 

Aha, someone who monitors charge temps and might be able to answer my query

Does the wrapping actually affect the charge temp on a FMIC? My thinking here is that the air flows so fast over (say) the hot turbo, that it doesn't have time to warm up before it's in the engine anyway. Did you notice a drop in charge temps when you went 'wrap'?

 

why not just wrap the turbo?

 

here is some of mine, same stuff as silent running. very good stuff, but very sticky as well

 

Looks good mate, where did you get yours from and how much ?

Yes that's exactly the stuff I use (as in the pictures above). As someone pointed out, it's the same as the DEI stuff - but it's a lot cheaper. Not there's not a time and a place for the proper DEI products, (e.g. the exhaust wrap) but with a basic item like this, I think one heat tape is much the same as another. The idea is to tape up everything within the engine bay which IIRC took me a couple of rolls of the stuff, maybe it was about £15 the lot, I can't remember exactly.

Now unfortunately I didn't do a 'before and after' on my FMIC pipes. When I installed it, I didn't want to pull it all out again and it seemed obvious to me that it was going to put more heat into the charge on the way into the FMIC from the top of the turbo, and the general warming effect of the offside of the engine bay, making the FMIC have to work harder. It also seemed obvious that the returned air from the FMIC was going to pick up heat before the throttle body, negating the work done by the FMIC.

So the upshot was, I taped the whole thing up before installing so I've no idea what the charge temp would have been without it. But having measured charge temps with various combinations of pipework, heatshielding, TMIC etc I have a pretty good idea of when something's keeping charge temps down and when it isn't. With the tape on, if I don't give it any boost, I can literally drive for half an hour without the charge temp rising from exactly what it was when I switched the engine on. It will soak up some heat if you park up for a while but within seconds it's back down to close to ambient again. However, once it's had some heatsoak it never quite gets down to what it was before, but it's still within 5 degrees of ambient in normal driving. On a track I might see 10-15 degrees above. For what the tape costs, if you're installing an FMIC it's a might-as-well job.

 

Good price, its a win win situation, i'd like to do it, does anyone have any links to the stuff?

Cheers

I'm sure I just got it off ebay.

 

I used Exhuats wrap with ally foil tape over the top of it on my original Autobahn88 pipes but haven't bothered doing the ones on my new Hybrid one yet.

Only did the bit direct above the turbo and the return pipe:
