Thread: Defender soundproofing

Welcome Duncan,
not sure in Oz,, but check out LRO mag for websites in Pommyland, they may distribute here.
If England is so cold,, why do Pommy heaters never work?

I found this site, but I dont know if they do mail order.

some of the testamonials are form the US so they probably do. the only question is how much $$$$?

Duncan I have a 2002 Defender with home made soundproofing and a Bruce Davis Chip upgrade. I purchased soundproofing material from a place in Brisbane which makes it for boats and just made my own. Seems to work ok. The chip upgrade actually gives better economy well drive as normal because the chip blueprints fuel delivery. However obviously when the extra power is required more fuel is used. Overall though my is just the same although my friends economy has improved (Disco 11)

If you are serious about driving a defender without hearing much engine or road noise...get the thickest peice of insulation you can find and wrap it around your head with Duc Tape!!

Seriously, I am looking at trying reduce a bit of the noise as the Defender is our "good" car and the wife bitches a bit (as they all do).

I am starting with some underbonnet insulation from that mod in Melbourne.

Then I will be looking at heat/acoustic insulation above the g/box and on the fire wall as the handbrake does get damn hot some time.

Once I have a go at these I will reassess what need doing.

Regards

Guys,
I'm dragging this out again as I am also investigating some noise reducing options. Bit of thermal protection around the transmission tunnel and firewall wouldn't go astray either .

I would like to know how you went.

I have scoured the internet and found several companies who have produts but I am still in research mode. If anyones want some links, here:

Material from where ?

Is the insulation inside or outside the cabin ?
If outside (eg under transmission tunnel) doesn;t it get full of sand or dirt and rubbish ?

How did you go about 'making' the soundproofing ? Was it just a matter of gluing it on in sheets? What adhesive to use ?

These answers would no doubt be of interest to others as well as my good self.

I have ordered the Noisekiller kit from the UK and am eagerly awaiting its arrival. It is said to reduce idle noise by 4db.

Also in the garage is a can of bitumen paint. This will go under the wheel arches, and on the doors after I pull the trim off.

I will do before and after soundmetering tests and keep you all posted. Stock, then soundkit, then paint.

More info, PM me. Anyone in Melbourne is welcome to come and see what difference it makes to my car when it's done.

Another good way to decrease noise would be a GKN overdrive. Now I've installed the tacho it seems we're doing an unsightly amount of RPM at 110.

Robert,
How much did the kit set you back if I might ask?
And where or who did you order it from?

I might just take you up on a peek later. I am in melbourne too.
