Sound Deadening.......what's Everyone Using?

Recommended Posts

In my enthusiasm to put the car back together I forgot about sound deadening....before I dive into this I'm keen to hear what people think of the various products on the market.

 

Looking at products like : http://trufitcarpets.com.au/index/resomat/ and http://www.dynamat.com/automotive-and-transportation/automotive-restoration/dynamat-xtreme/

 

or are they a waste of time?

 

Thanks.

 

David

Dynamat off eBay USA. I got two packs for what autopro were selling for one set. Added maybe 15kg but quietened everything up heaps!!

I ummed and ahhed about this for some time because I changed from an original idea of a full leather interior, a la road Ferrari, to a spartan interior, a la race Ferrari, after seeing real GTOs at Goodwood and Pebble Beach.

 

I liked the Spartan look (and it was cheaper!) so I've decided to try using the car with no insulation nor sound deadening for 12 months. So far I've only been on 50km runs but I haven't found the noise or heat an issue - I do have Vintage Air installed but I haven't run it.

 

The extractors a ceramic coated which I was told would make a big difference but apart from that I'll be starting from a raw base (except for 2 pak paint and anti-stone chipping underneath) and observing how it goes through a Summer and Winter before considering further options.

My audio guy that does my high end stereo installs uses dynomat, But only in specific spots to reduce resonance.

That's all the experience i have as i often take the weight out of my cars :)

Dynamat, have only done this in the foot well floors when I had the rails replaced, the rear area still has the original tar deadening. Then under all carpet Dynaliner stuck to the bottom, finally had the carpet loop edge bound to look original. This has given me a good result. Photos are of a test section I did for the passenger side with some house carpet.

David, we used 'Car Builders' on my mates Escort:

http://www.carbuilders.com.au/

 

It's exactly the same a Dynamat, but it's quite a bit cheaper. The Vic supplier is in Dingly village.

Installation note: work out how much you need, then add half the amount you need again - my mate worked it out, but we still ended up needing more...

Sounds like they are much of a muchness....all do the same thing.

 

Peter, I contemplated the same spartan interior but I know what Im like and the chances of me pulling everything up to do it at some time in the future isnt high!

"Carbuilders" , great product & relatively easy to work with . You wont beat the price anywhere .

Apart from the "Sound deadener one" they have an additional rubber water proof product that you can incorporate with it . Talk to Brendan at the suppliers he'l advise you .

Yup Carbuilders and then finished it off with silver insulation ducting tape from bunnings...

Holy Sheet! You know its not a Bentley yeah?  Why are you guys so keen to add so much weight to your car? Like i understand a bit around the transmission tunnel and foot well area as it can get quite hot.

But its a zed? you dont drive it to work and back everyday?

I don't have any insulation in my car and honestly it is not bad or loud. I would put a tiny amount in the footwell where the exhaust tucks up along the firewall and maybe on the sides of the transmission tunnel to reduce heat. Anywhere else in my opinion is overkill.

Thanks for all the responses guys.

 

I kinda agree with Agno and Peter Allen, one of the concerns I have with the BMW engine is that it will be too refined and lack any "character" so allowing a bit more NVH may enhance the experience....and as Jake points out its not a daily!

Dead easy...pardon the pun!

 

Without it mine would have been almost unbearable on a long trip.

I used fatmat rattletrap xtreme (the more expesive butyl one) throughout the entire car ontop of KBS killrust and spray deadener...car is still loud.

 

Im running twice pipes with no resonators and triple carbs with open trumpets which probably doesnt help.
