My gti doesn't have any insulation under the bonnet, but is it worth getting any? Does it make much difference?
-
nope no need for it
-
Mines in the bin :cool:
-
mines in my garage, jinks (my cat) uses it to sleep on while i work on the car
-
Not really needed unless you have a diesel.
-
Doesn't it reduce noise while driving along? :undecided: Was thinking of getting one considering the noise reduction
-
I noticed quite a significant reduction in noise after fitting insulation to mine.

hold too much heat in the bay
-
I found it transferring heat to the bonnet do put it back in.

Did you use a heat gun? Did you take a engine bay temperature before and after? Or just place your hand on the bonnet and thoughts that's hotter than before, it must be taking heat away from the bay and transferring it to the bonnet?
I think you will find that it's holding heat in and the bay and bonnet temp will raise.
It does not transfer heat from the bay to the bonnet! :rolleyes:

Think its just sound

:grin: agree with tweed

Remember I have a turbo at back creating more heat than usual.
After getting bonnet painted, I noticed the paint needed polishing again after a short while. The painter mentioned something about too much heat causing faster paint curing or sinkage. The only thing that I'd done is removed bonnet insulation. So replaced it.
Just like a phenolic gasket it doesn't stop heat transfer, but I think it slows transfer And for the phenolic gaskets on my inlet manifold test l, I measured temps before and after as shown in my thread. . :wink:

That makes sense! Unlike your first reply :grin:

Iv never had issues with my paint on my bonnet Russ, and as u know I have a big turbo on mine
The insulation on the underside of the bonnet keeps the heat in the bay too much IMO and that's not what I want
They also hold moisture too and go damp if the car is not used for a few days (in colder months etc) leading to oxidization of parts of the engine
This is just what I found personally and that's why mines not fitted, oh and also because my engine cover is pretty close to my bonnet as it Is :grin:

Cold and damp! The joys of northern life eh?? :evil:

Hahahaha :grin:
