Under Bonnet Deadener

[jase33]

As it says. what is its purpose, and is there any harm in removing it? Its taking the shine of my piping and stuff. Its on a series 2 r33

You can remove it, it acts mostly as a rattle deadner. Perhaps a little as a heat barrier. Im thinking not to refit mine for a cleaner look.

i always thought it had some fire retardent thing also. that doesnt make sense now that i think of it.

anyone know where to grab a new one??

Just something to think about, if its taking the shine off your piping, then if you remove it wont it scratch your piping instead?

[PsYLoR]

Mine was haggard and loose and was marking the piping & strut bar, took it off and all is fine, no scratched piping.

Nissan will sell you a new one.

it also acts as heat resistance, if you take it off the paint on your bonnet can heat up and crack etc

your piping shouldnt be touching the bonnet anyway, should be mounted lower if it was done properly

When my car got checked by my a friend at xspeed, i ask him the same thing, as i know the car engine will run cooler without it, but he mention what karl said in regards to the paint. So left mine on..

its been removed. no more scratching. the piping is fine where it is. the old liner was just a bit gay. if the paint melts or cracks, ill just get a respray. crisis over.

Many cars don't come with liners either (I realise that the cars I refer to are generally n/a runabouts not turbo performance cars)

Funny you mention that,

I just got back from a track day in the 33. And after 5 hot laps and a cool down lap, i usually pop the bonnet right up and let it idle down for 3-4mins. Both with the Skyline and my Integra R.

I noticed straight away that the immediate heat under the bonnet in the ITR was suprisingly ALOT hotter than the Skyline, IC pipes and Intake manifold were "cool", and so were the brakes! ( brakes being able to actually touch the caliper for a few seconds, but in the ITR, i couldnt even touch the wheels they were red hot, to the point the wheels changed colour to a burnt yellow/brown, lol.)

Possibly because the Headers are at the front giving of the most heat, but i found it a little odd.

Aftermarket CF/Fibreglass bonnets dont have shields do they? Havnt heard about too many heat related problems. Anyone has?
