Will this be okay?

It won't cause any problems?

Cheers,

Michelle.

It will (at the chance of being a complete Muppet) make the noise level go up for your car.................

Not the children, won't somebody just think of the children. All that noise coming out of your car...

Seriously thought it may also allow heat marks to be created on the inside of the bonnet, therefore perhaps more heat will get out....whose knows eh...

Michelle - That isn't sound proofer - That is a 'ickle blanket to keep your oil warm on frosty nights.

Seriuosly though - you should be OK taking this off as long as you keep two little peices the size of a thumbnail

Cool

Before applying the blanket, prewarm it with armpit displacement. Preferably w/o anti perspirant. The salts will cause small deterioration areas in the reflective surface.
(does this help?)

I'm not sure about any mechanical effects but you my find the 'sounds' aren't as well 'deadened' as they were!!!!

Depends on what tool you use... an axe might cause problems in the long term.

Not entirely sure on this one, but you may find it does bad things to your paint. The heat is distributed by the sound deadener. If you remove it, you may get "hotspots" like on the bottom of a thin pot. This may cause the paint to discolor unevenly with age, or even perhaps to peel in some places. I'm really not sure of all this, but the thought comes to mind.

'Chelle - are you doing this for weight saving purposes? You might get some paint discolouration on top of your bonnet as well. Much better to lay off the mars bars and ice cream..

Indeed. Helps avoids those nasty stains on the seats as well, assuming they are ice cream...

I've taken it out off bonnet, I did notice more people turning around as I came towards them.

It seems to improve safety as the peds and cyclists notice me more.

Chelle, don't remove it!!
The removal of this will cause your car to never warm up on cold wintery mornings, thus resulting in freezing windows and freezing ar53.

but it will allow the engine to run cooler, especially beneficial for track days.
no discolouration on my *****, but it is black.

Cryptwalk - I put a blanket over the engine at night, it starts okay in the mornings.

I was thinking of taking the lining out of the boot as well to see I could amplify the back box more as well.

If you are a resident of a tropical or semitropical area, then the removal will contribute to the overall cooling effect needed to enhance the engine performance.

A better idea (worked on mine) is to remove the backbox, get a drill put a 10ml metal drill bit in and drill a series of holes in it. Thus resulting in a louder and deeper sounding backbox. Result.

Billbill, would it be possible to further enhance the engine cooling by supplying a cooling agent to the engine as a whole?

Do you know where I could get hold of some liquid oxygen, or at a push liquid nitrogen?

Cheers

Liquid oxygen is not recommended because of the corrosive affect upon the exterior surfaces with the engine compartment. Especially when used as an open spray. Also there is a distinct possibility of ignition of this flammable product.

But what if it was piped around the engine bay in a sealed unit?

I would highly recommend the liquid nitrogen concept. Emitters for same must be placed to apply the inert liquid gasses in the appropriate areas.
You may obtain bottles of Nitrogen, reasonably priced at: LiquidNitrogenofIdaho.com
A subsidiary of one of my many companies.

Don't like the sound of the paint discolouration, how about if I leave bits where it is likely to occurr?

Does it affect the MY94 paint? (code 406)

70deg.C., is that an excessive temp in deg.F?

I found my car so loud without the sound deadening that I had to replace it. Unfortunately I couldnt run to the IM price so in best Blue Peter fashion I have used the 13 tog duvet off my bed, which appears to work really well. At least it did until for some strange reason I met with a really helpful bunch of chaps in a big red lorry, who were all wearing really sexy yellow plastic trousers.......

So there would be no long term negative effects with liquid N? That is great news, thanks for website, I'll go there now.

Of course introducing the cooling agent may actually avoid any chance of paint damage, so the benefits are massively increased.

May discolour your interior.......ever thought of that............

Also the surplas material could be reused as 4 mudflaps for your car cut to fit perfectly. This would also reduce the noise from your tyres as they would be sound deadening..

MichelleWRX1994, I am sorry to inform you that code 406 paint is adversly affected by both oxygen, nitrogen, carbon dioxide, H2O and various commercial wax preparations.
Would recommend you contact Scoobypaint.com to rectify your embarassment.

'Chelle - the paint discolouration shouldn't matter to you specifically. Do you not normally get the front end sprayed every three or four weeks anyway?

Stop there's a cheaper way!
Simply re-route your blowers using a load of piping from b&q into your engine area, then slap your a/c on full.

Cheaper than liquid nitrogen and less explosive!
