Dynamat Weights

Dirtbag · Post by **Dirtbag** » Sat Aug 25, 2007 3:10 am

Could anybody give me a general idea of how much weight would be added to my ae101 trueno by dynamating the floor from the pedals/firewall to backseat?
Im really only looking for a guesstimate, eg less than 10kg worth of dynamat, <20kg etc etc

about 20-30kgs.. entire floor = 2xbulk kits (if not more)

what are you planning to do ? there are a few options out depending on what your trying to achieve

is it to cover up a loud exhaust ?

Nah, just to cut down on road noise. When i had my doors dynamatted I noticed that the car was a little quiet inside.

Was looking at doing from the upper footwells at the front of the cabin back to the start of the back seat and maybe some of the boot with the offcuts from the rest of the car, how effective would it be at reducing the noise?

very. but it sould be even more effective on your monies to find a cheaper alternative for the whole floor. bostick? even just using de oxidised sand

There are products better suited to doing your floor than Dynamat, PM DeeCee for answers

Or I may reply later when I have more time.

why PM me?

and don't listen to pjay and his sand rant = bad idea! (i keep telling you PJ

)

anyhoo..

mass loader, dampening, barrier, absorption - whats your flavour?

if you trying to cut down on road noise, then we should be looking at barrier/dampening and absorption.

Dynamat is barrier and dampening. Will decrease noise by creating a barrier that noise has to get through and transfer noise energy to heat (apparently)

Foreman insulation have a couple of different materials for noise reduction, but overall, DX would be easy for you to obtain and buy over other different materials that require a bit more installation thought over peel and stick.

if you are on budget and want to save weight.. at least cover areas near the wheels - front foot wells and rear arches to minimise noise from tyre contact with road

Fill footwells with concrete???
