Thanks for confirming, like i tought in the air collector manifold.
Maybe silly question but did the Shop had an estimate how much fluid the injection would draw per miles?
Since my car is a daily driver, trying to estamate how big of a tank i would need to add...

[finance-nick]

i use around 5 litres every 4 weeks with occasional blasts, but when really going for it, id use 4 litres per week in summer months - just fyi

Thanks for the info (rough idea how much miles/km you drive a month ?).
Kinda lean throughwards the snow performance stage 3 kit here.
It was bit a shocking moment when i stopped after driving the car..big smoke clouds, but luckly i knew it was normal.

Big smoke clouds? not sure that's normal? please elaborate
also best set up you can buy IMO is Devis Own, its incredible !!

[dasquade]

The manual clearly said some smoke (insulation settling itself) is normal . I might need to clamp a few parts where the tape released itself...

[finance-nick]

What manual?

[dasquade]

The manual of the heatshield material...

[dasquade]

You’ve finished installing your freshly wrapped headers and exhaust, but a few minutes after firing up the engine, you notice wisps of smoke coming from the engine bay and exhaust. You open the hood and nothing is on fire, but your freshly installed exhaust heat wrap is smoking like it’s going to catch on fire. Not to worry—this is actually normal for newly installed exhaust wraps that haven’t yet been exposed to heat.

The manual of the heatshield material...

Ah yes, that will be grease from your hands burning off

[finance-nick]

Considering the manifolds/turbos/downpipes shielding a wrap .
Sadely run out of material to cover the underside of the turbo's, not sure if that is a bad thing or not (will be difficult to do it anyway) but should be better then nothing i think?
Will try to log some more over the following days....

how many sheets of heat sheild did you use in total?

[dasquade]

I had bought 2 sheets ½" x 10" x 36".

Great thanks, how is car running?

Are you planning on rolling road before and after to see what difference this makes?
I get the lower temps you are recording but does that actually translate into anything useful?

You got lower temps? Can you elaborate

[dasquade]

Any body an idea where i could find the lava heat sleeves online? I tried to find them on ebay etc but couldn't find anything :s.
*not sure if it is better to just sleeve the 'cold' oil/coolant lines and leave the 'hot' oil/coolant lines unwrapped so some heat can already escape before getting cooled (and so putting less stress on the heat exchanger)? I think the manifold/turbo/downpipe are the biggest heat producers, so that should already help alot...

Well, i had my 'before' temps i recorded some weeks ago and already have some 'after' temps, but didn't wanted to push the car too much (after seeing that BIG smoke cloud this afternoon :p). So i'll let it 'burn in' slowly for a week i think and then do some simular testdrive/recording to compair. Like i posted before, a lot depends on ambient temps for starters, but the 'delta' (overall difference) should be some what of an indicator where it helps .
The main reason i did the heat shielding was the high intake ambient temps (IAT) before it enters the charge cooler. Those went up to close too 140°C, but offcourse gets cooled down to roughtly 50-60°C by the heat exchanger. Any lower IAT (especially before the exchanger) would help as the system already is under big load since there is only 1 cooling system for everything (coolant is 1 system and not divorced, oil the same).
Do a little test, open your hood and let somebody rev the car and place your hand on the rs airbox holes and feel how much air it sucks in!! Imagine you driving and engine bay is filled with manifold/turbo/downpipe and all other hot air it is blasting out in that packed place.
Heat shielding is one way (all in all it wasn't expensive so far). Next will be most likely adding water injection system as that helps cool down IAT (after charge cooler) big time and if we can use logs 'forgot username' posted, that system apperently can provide stable results .

Personally doing it mainly for better stable performance/maintance.
SO basicly, the aim is to get heat out the car as it is supposed to be, through the exhaust pipes and not radiate into the engine bay, resulting in lower IAT that will keep performance more and lower stable. Heat is a big killer!
