Heat shielding for under the bonet

Not my best work but doesnt do a damn thing.
So the question is, should i have NOT push it down theough all the nooks and crannies, should i instead of just stuck it to a few places and left a gap between the hood and heat shield creating a barrier?
if it doesnt really matter then i can tell you this stuff i got doesnt do a damn thing, infact the outside feels like its hold more heat than inside outside is about 130F and inside is 105F at its max’s and turbos hottest unshielded area is about 230F
this is after about 20 min after ahutting the engine down

Looks like you have put another lid on the saucepan ?

ie it's holding heat longer, and reflecting back into the engine bay

That’s the whole point of a heat shield it’s to protect the hood from getting too hot but it’s actually having the opposite effect

A typical heat shield does not contact the surface you don't want to get hot. You need to have an air gap between your "shield" and the hood.

The best thing you can do is to insulate the hot side of the turbocharger, it'll drop the under hood temperatures dramatically and it is good for the turbocharger, increasing tit's efficientcy.

This is what I put on my car. http://www.waymotorworks.com/wmw-turbo-heat-shield.html

This. I bought a PTP turbo blanket from Detroit Tuned and that did more for under hood temps than my AEM intake, AEM heat shield, gold heat tape, removing the hood scoop grill. I can do multiple back to back hard pulls, have a red hot downpipe and put my hand directly on that blanket and it's mildly warm.

Not sure what heat shielding material you are using, but I find Zirotec do good material for this kind of work

The turbo blanket really helps and then you add the stock shield back in place and it really cuts down the heat and holds in place very well! https://www.detroittuned.com/mini-co...turbo-blanket/
