Insulation for heat and sound.

[skullandbones]

Short story: Rented a little car in the Cayman's to explore the island. It was like riding in a "tin can". It was so bad (got worse the faster you went) that my wife and I couldn't stand it. Returned to the rental place and exchanged for a real car. I guess you can see where I'm going with this.

This can be posed to anyone with experience (good or bad). You coupe guys may be a better sounding board (ha) as you are in an inclosed space.

I'm insulating with Ultra Hussmat by Summit Racing. It has good numbers for heat and the dampening works for sure. I had a friend who used it on their GS and it rode and sounded very solid. I can't get over how it dampens areas next to it that are not even covered, yet. Next, I am using a dense rubber closed cell underlayment used in flooring about 1/8 in. Next, I have a premium carpet mat about 1/2 in also very dense. Of course, the FFR carpet is the last layer. There may be a couple of areas where I have to fudge a little like the accelerator pedal area.

So what do you think and how well has your treatment worked for heat and sound insulation?

Thank you, WEK.

I'm happy with mine, after finally getting to drive it in the heat of summer.
Floor and foot box heat transfer was virtually non-existent.
There was heated air from the engine compartment, passing along between the body and the foot boxes, as I haven't added anything to block this area off yet. (In the cooler weather this isn't all that bad, as a supplement to the heater)..My foot box cooler fan was only turned on a few times, and this was only when I was stuck in traffic..

I used double sided aluminum backed insulation everywhere in the cockpit, as well as adding Dynamat to the flooring in front of the seats. FFR carpet finished it off.

I forgot to mention that I think there is a difference between "sound dampening" and "sound transference". There is probably not much that will eliminate the latter based on what I have heard in past discussions but maybe this will muffle it a little. Thanks, WEK.

With the side pipes, I couldnt hear a rattle if you paid me. Fiberglass doesnt rattle, and with rivets and silicone, neither does my aluminum. With out a top, you will never have a quite car. :)
