listy Posted February 23, 2013 Share Posted February 23, 2013 Looking to Dynamat the whole floor of the supra, including under rear seats, boot, up the rear quarters, and do the doors,(pretty much everything up to window height really) to try and make it a bit quieter on the inside. Has anyone done this and know how much I will need? It's not overly cheap stuff, so don't want to buy too much more than I really need. I'm sure there was a thread on this a year or so ago, but I can't find it Either the above, or has anyone soundproofed the supra with anything else?

Josh42 Posted February 23, 2013 Share Posted February 23, 2013 Use flash tape from B&Q mate, same effect and a lot cheaper! Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted February 23, 2013 Share Posted February 23, 2013 Lee at SRD has recently used it on one of his builds Quote Link to comment Share on other sites More sharing options...
Tyson Posted February 23, 2013 Share Posted February 23, 2013 I believe Jamie P had it on his supra. Quote Link to comment Share on other sites More sharing options...
Littler Posted February 23, 2013 Share Posted February 23, 2013 It's all bin fitted to Jay's car (or an equivalent) so Lee will be the guy to ask Link here I've done all the rear have of my car and the difference in road noise was quite dramatic, also helped with my sub which was the main aim. Can't remember for the life of me how much I used though Quote Link to comment Share on other sites More sharing options...
hackin_n_bashin Posted February 23, 2013 Share Posted February 23, 2013 Use flash tape from B&Q mate, same effect and a lot cheaper! I'd go with this mate, use flash banding. Quote Link to comment Share on other sites More sharing options...
Rob W Posted February 23, 2013 Share Posted February 23, 2013 I got about 4sq.m and with that I managed to do the boot, rear quarters, under the rear seats and the doors. Still had afew sheets left over. When I get more time I might do the floor and the roof aswell. Quote Link to comment Share on other sites More sharing options...

listy Posted February 23, 2013 Author Share Posted February 23, 2013 Cheers Josh. Perfect I also need to 'rain proof' the doors, as when I had the door cards off the other week, they were damp at the bottom. Would that weather proofing tape do the job, if put around all the door edges? Quote Link to comment Share on other sites More sharing options...
Alex Posted February 23, 2013 Share Posted February 23, 2013 I did mine with dynamat thin n lite - pictures are in a thread in Ice section. Ive now gone to town on the doors with Skinz and they now feel proper solid and not tinny :-) Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted February 23, 2013 Share Posted February 23, 2013 I am thinking of getting mine dyna-matted as the noise created by having TRD engine and gearbox mounts is annoying, road noise reduction as well, I am also keen on getting the car fully undersealed Quote Link to comment Share on other sites More sharing options...
Abz Posted February 23, 2013 Share Posted February 23, 2013 I need to do this as well, the less "road noise" the better for me when I am doing long trips. I'd like to sit at 60mph & for it to be a bit less noisy though it could be the Falkens causing some of that! Listy check out some YouTube video's if you are planning on doing it yourself. Also JamieP mentioned to me something about a foam thing in the arches area. For the life of me can't remember what he told me but apparently reduces road noise by quite a bit!

imi Posted February 24, 2013 Share Posted February 24, 2013 Use flash tape from B&Q mate, same effect and a lot cheaper! How effective is this as compared to Dynamat? Quote Link to comment Share on other sites More sharing options...
Lee P Posted February 24, 2013 Share Posted February 24, 2013 How effective is this as compared to Dynamat? It can work but not as good. You need to use alot more of it so the saving isn't worth it. The stuff I use is cheaper than the branded Dynomat and is very good. Quote Link to comment Share on other sites More sharing options...

Abz Posted February 24, 2013 Share Posted February 24, 2013 What sort of cost to dyna mat a supra Lee, could you quote a cost on this too? Fitted? I'd imagine to reduce noise doing the rear boot & door cards would be best? Quote Link to comment Share on other sites More sharing options...

Stevo Posted February 24, 2013 Share Posted February 24, 2013 If you want it quiet, you need to approach it from a 2 layer solution - 1st layer down needs to be a sound 'dampener' then that is followed up by a sound 'barrier'. The dampener has weight to it (such as dynamat) and reduces sound resonation by deadening the vibrations. Using this on a metal panel will help stop noises being amplified through the panel. Very good results can be achieved by covering only 25-30% of a panel without going hell for leather and covering the whole thing! This is cost effective and avoids adding unneccesary weight. The noise barrier goes straight over the top of the deadening material and is usually made from a closed cell foam structure (in varying degrees of thickness) which absorbs airborne noises and also acts as a thermal insulator. The barrier ought to be laid without any gaps and using acoustic edging tape where sheets meet each other. They are typically cheaper to buy than the deadener mats. I've done my doors, rear seats and floor so far and its made a big difference to my NA running a HKS Hi-Power. Especially low-end sounds when on the motorway.

Stevo that is fantastic information, thank you!! I wasn't that fussed at first but now with the little one I want to make the cabin as quiet as possible when we do the long trips. Do you have any pictures or recommend any products? From what you have done? Quote Link to comment Share on other sites More sharing options...

listy Posted February 24, 2013 Author Share Posted February 24, 2013 You nutter!! An also sorry for the thread hi-jack Lol I figure the more I do, the quieter it'll be. Lets face it, my car is 20 this year, and it isn't exactly quiet in there. And, like you, have a little one, so the quieter the better. I won't do it all at once. Start with the back seats and floor first, then boot, then doors. Spread the cost Quote Link to comment Share on other sites More sharing options...
