Hello there. I want to reduce the noise coming from the engine compartment, so i thought of putting this product

http://fasterthansound.eu/index.php?pag ... 1&Itemid=2

behind the allready existing sound dampening/protective sheat sitting under the hood.

At first, i was worried that maybe during the summer, when it's really hot, the material would loosen, and perhaps even melt from the heat coming from the engine.

However after reading about it, specifically on the page i mentioned above, it seems its operating temperatures is from -45 to +130, and i doubt my hood will get a 130 celsius, even in the summer, when driving around in a city.

So then i thought of problem number two: What if the material increases the heat? the material has an adhesive plastic something something one one side, allowing it to stick to the hood, and the other side is made of what i assume is aluminum.

My question is, will the aluminum increase the heat in the engine compartment? I mean i plan to put the protective/sound dampening sheat back on top over the STP mat, and the hood itself is also metal, but, yeah, just thought i'd ask first to see if someone knew, as it would be sad to waste precious materials if its just going to melt, overheat, and destroy my car

Also, if someone have done this, or something like it, that would be interesting too.

I have thought of using some lighter, soundproof mat, you know, the kind that is nonsticky and made out of a softer material (gee, i have really run out words to use here to describe what i mean, so i hope you know what i'm getting at -_-)

yeah well, sorry for a messy post and all.

Thanks in advance - Jacob

erm, i looked further on the site and found this

And it actually says its used for the engine compartment. But also it says not to use at temperatures above 100 degrees. I'm worried that if it's 30 degrees outside, and i'm standing at a red light or something, temperatures will climb above that.

or perhaps, the cars fan will be on more often, and actually working against what i want to achieve by sound dampeníng the car. help! :P

You can get soundproofing like that specially designed for the engine bay mate = sure ive seen it on demon tweeks?

The one you mention is Vibroplast M1 is for hood and engine compartment.
I think you should look the opportunity to put damping sheet to fire wall which will give better result but it need to remove console

Ah, you mean putting it inside the car, and not on the engine compartment side of the bulkhead/firewall?

yes it been design to put inside of car
the engine compartment side already have a sheet of fibre glass to reduce noise from engine and difficult to put any damping sheet
But.....you need to remove console...........it will take a lot of time

Yeah, it will But eventually, it will have to be done!

really, the only question i have is: why?
it's gonna cost you money, time, and most of all performance (add the weight of the sounddampening stuff to your car weight, there ya go).

how much noise reduction do you plan on getting?

well i have about a 100 kilos of sound equipment in the trunk, so half a kilo of sound dampening material seems like it doesent matter

hehe well after all it's your decision. i'd recommend putting it in the engine bay though. soundproofing-materials work by absorbing sounds, rather than keeping them 'out' of a certain area.

thats why in, for example recording studio's, the soundproofing is on the inside of the room, rather than on the outside
