bonnet insulation?

just a quickie... the insulation on the bonnet is there to what exactly? keep noise levels down? keep heat in? protect paintwork from heat?

if the paintwork is fine without the insulation and its sole purpose is to keep noise down then wouldnt it pay to remove it to allow more heat to be disappated thru the bonnet resulting in a cooler engine bay?

just something thats been on my mind.

noise is really not a problem to me, i dont mind it. if the paint would be damaged by excessive heat (i muchly doubt) then fair enough. if not its going.

paint operating temps are like a foreign language to me... know sod all about paint!

can anyone give me a genuine reason the insulation/lining whatever you prefer to call it is there?


oh, and yes, i do have *force every possible hp out* on the brain!

Re: bonnet insulation?

Older cars do not have an insulation, so I'd figure it's there only to remove noise...

I'm not so sure it would actually make the engine pay any cooler
