Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Sound deadening material.

i got the ones from "phonak". swiss company.
i use them for driving the m3w and for pistol-shooting. they are great! you can talk to each other but the "bad" sound is turned down!!! excelent

Bevel box and belt noise.

Thinking ahead, I contacted Dynamat and this is their reply;

'...... using our Dynamat Xtreme on all areas of the interior and cargo area, and Dynaliner on the floor and firewall, the vehicle will feel more tight, solid, and cooler.

Xtreme is a peel and stick product that will damp vibrations in sheet metal and/or fiberglass and will give the vehicle a more solid feel when driving, and make the doors sound more solid when closing.

Dynaliner is a closed cell, peel and stick foam that when used over the Xtreme will reduce the amount of engine heat felt through the floor/firewall . Dynaliner is available in 3 thicknesses: 1/8, ¼, and ½ inch. Use the thickest one possible in any given area for the best results.'

Many would keep the noise and feel as this is what Morgans are about, and some would say that is why you have one. But I offer Dynamat's reply for those who may like to calm things down a bit.

A traditionalist, I am not sure yet.

Neil, I lined the footwell, floor, sides and back if the passenger compartment on the Roadster.

Dynamat Xtreem does exactly as it says, the reduction in noise and heat was significant, even without the Dynaliner.

Fitting it is tedious and you need a lot of new Stanly Knife blades as the backing is quit thick, soft aluminium sheet. The stuff is also very sticky, once fitted it isn't easy to remove! Measure twice and cut once and make templates from card where needed.

There is a thread here with details. I'll see if I can past a link to it.

I suspect it would help a lot in the M3W, but I'd add the Dynaliner on the floor and rear bulkhead.
