2019 Polaris Titan Sound Deadening

Builder: North Dakota State Clean Snowmobile Challenge Team

Type of Project: Annual competition to quiet down a snowmobile

Products Used: 27 Sq Ft of Damplifier Pro Deadener, 2 gallons Spectrum Liquid Deadener, 18 Sq Ft of Luxury Liner Mass Loaded Vinyl, 8 sqft of Mega Zorbe Melamine Foam, 16 Sq Ft of Thermal Block

What to look for: NDSU team strategically uses butyl to stop vibrations and strengthen panels. Spectrum is applied to the core body of the sled and also to the skis to further reduce those structural vibrations. The team then installs Luxury Liner on top of the Damplifier Pro, below the seat, and even on the side as a skirt like you'd see on a military tank.

Installing Damplifier Pro on the Polaris Titan. Look at that t-shirt! He's a pro.

The snowmobile panels were fully skinned with Damplifier Pro. This stops the vibrations, and maybe more importantly strengthens up a very flimsy part of a snowmobile.

The panels and body of the snowmobile are fully lined with a layer of Luxury Liner Mass Loaded Vinyl to block the loud air borne noises generated by the engine, exhaust, and tracks.
