Decided to order 2 sheets Heatshield Armor Downpipe Shield Kit ½" x 10" x 36" (155.82£ shipped to Belgium).
In the first place to wrap the manifolds and hot side turbo's. Not sure if wrapping the cold side is a good thing (the aluminum might be better of unwrapped).
I'll see how far i get with those 2 sheets, maybe with the rest i should be able to cover half of my downpipes and the oil/coolant pipes of turbo's. Altough maybe again it is best not to cover the hot lines so heat isn't trapped, but cove the inlet lines and prevent them from heat).
Will see how it goes...

epic, well done take some before and after shots and heat measurements with a cheap laser heat gun, will be so interesting. no need to wrap the actual turbo, just the manifolds will create the seperation needed ;)

when can we look forward to the results?

Well i mailed heatshield aswell and asked more detailed info what best to do and what not. Keep you updated.
Might take some time, might do it when i swap coils (and the new NGK plugs). Won't be easy and don't want to remove too much items to get to the manifolds.
But will see what i can do. Definatly will wrap the hot side of turbo's aswell and see what is left to cover DP's. I don't expect miracles but hope i can enclose most parts decently and reduce surface heat (some heat will still excape here and there i guess but better then nothing).
I have cheep laser heat gun, so will try to at least make some before and after data (but hopefully also with internal engine temp data).

For what it is worth, got some feedback from heat shield itself.
No mentioning of the manifolds but i guess it is fine to fully cover them (will be a tough one to do but guess anything better then uncovered).
For the hot side turbo, they recommand not to fully cover it but only half side. I assume it is safe to cover the side that is facing the cold side (more or less where it is covered but unisolated atm with OEM heat shield). That side apperently needs to be able to "breath". Cold side, as suspected, is not allowed to be covered (as it would have the oposite effect). They advice our product for the oil/coolant pipes, but just as it would be easier to work with (not planning to take out the pipes to slid over a sleeve, so will see how the heat shield is to work with).

Just a quick overview of the temps i'm getting atm after 15min dialy drive (normal driving + a few WOT's), stopping car and infrared surface temps...
Ambient air: 11°C
Oil temp: 102°C
Cats: 390°C
Manifolds: 300°C
Turbo: hotside 260°C / cold 90°C
Intake tubes (heat wrapped): 75°C
Airfilter: 50°C
Coolant reservoir: 80°C
Metal air-water charger: 55°C

A guy on here is selling the plugs you need because he sold his car before using them. If interested let me know and I'll find his message.

I'm booked in for the aquamist system installation on Thursday.

Emailed loads of turbos options. Let me know if you need some direction.

How about the manifold itself after a hard drive? that's the big question !!
take the measurement just under where the air intakes go across

My bad, forgot to add the manifold temps...added to original post as reference. It was 300°C (guess it cools of quicker then the turbo/dp metal as it it thinner, but that makes me wonder how warm it gets during load! Exhaust gasses around 880°C, offcourse double sided shield construction the manifolds but suspect it gives of A LOT of heat.
Cool about the aquamist :). Will you be running water only or water/meth combo. I was thinking water only as meth needs tune.
If possible please review and pictures (especially where they plan to feed it, some did it after charger inside the plastic air manifold on the front, 2 nozzles.
No real plans for turbo's here atm, atm all the 'mod' are more to get a more reliable and longer life engine :). But never know...(a set of RS turbo's instead of me S turbo's would already be nice).

*it was me ended up buying his NGK R plugs ;). Altough i had just bought OEM NGK "M" plugs and installed those 200km ago, will be replacing them together with RS coils (and keep the M plugs as spare or try to sell them, they are the same in OEM RS and S these days).

WOOOOOW, once those manifolds are covered, we should be in a different world !!

im struggling with Heat Shield Products to get a straight answer about why they recommend the manifolds should be half wrapped to "breathe", but when i asked "why do they need to breathe" they were quite rude by saying;

"Ive already told you twice, it can invalidate the manifold warranty"

Great customer service i'd say, they did say their product holds in more heat than others, but they won't tell me the consequences of fully wrapping a manifold. :FIREdevil:

Water cools better than 50/50, but the octane gives extra power, you can run without a tune if you don't spray too much

Hmm thanks for mentioning! They didn't told me anything about the manifolds aswell and i did asked too.
Like mentioned earlier, i used to read a topic (maybe not audi related) about manifolds and some said it is good, some were against it :s.
The last thing i want is indeed do more bad (in the long term) then good. For the turbo's i kinda understand that it is not too good to fully wrap them (on the other hand, i have seen a lot of thermo coated hot sides and what is the difference with those turbo bags altough the bag don't cover the underside i think).
I might try to look it up a bit more before i add the shields ;).

Yup it was in the first please to cool and get better ingition (and steam cylinders). It is still on the wishlist, once the kit is installed one can still choose what you do :).

My bad, the manifold they call it turbo fold :) and that was what they recommanded to only cover half and it makes some sense.
The thing that can cause an issue it that the heat doesn't escape too fast and starts to heat up the cylinders head or start cracking the manifold itself.
Think it is best to indeed only cover the top side (inner V side). I noticed the throttle body actually has a thin layer of heat reflection material...
So i got it wrong on the hot side of turbo, looks that can be fully wrapped. In the end you will end up with some gaps anyway i suppose as it won't be that easy to get in all corners and under it.
In an other topic they did a test with those turbo blanckets on a mazda Miata. Turbo inlet temps (outer surface) got reduced by 27°C (from 110->83)! That alone is a good gain in my eyes as that was more or less what i was after: reduce IAT before throttle body (normal driving around 50-60, but peaks to 140°C under boost and still cold outside atm). Any drop in material heat soak will help :).

Think i forgot to say it...but it was me who bought them ;). They should be on their way :).
I might do the heat shielding when i do the plugs (need to make space in engine bay anyway for that...).
