My engine pad is crumbling. I was thinking of replacing it with Dynamatt. Has anyone done this? I think it looks a little nicer and the sound deadening properties are nice. What are your suggestions?

Any pics would be appreciated. Thanks again all

Pelican parts have an option that I used, I am pretty happy with it since it fit and was easy to install.

Don't be surprised at what you find when that pad comes off. I had a hole on both sides.

I'm using a dynamatt copy.

I'm using nothing

If I do sound deadening it will be inside the weatherproof cabin behind the backpad.

I also do not use insulation or a pad on either side...no problems here. Between the two choices you listed - I'd choose Dynamat hands down.

Mine is inside the cabin. Nothing outside to trap water.

As others have stated, do some form of dynamat (or other vendor sound deadening product) on the inside. There are some good threads here on this board of people doing dynamat all throughout the interior.

Here is what was behind my engine pad:

914 Rubber has a nice Velcro removable one. Just took it out of one of Mark's cars.
I just spent 2 days removing the residual Dynamat tar from one of the rally cars we're building at Rothsport. Nasty .................

At $86 these are the best value I've seen

So I.m wondering.

I can only wonder what the engineers were thinking when they put the pad there. My quess is that it was to stop heat transfer as well as sound...with more emphasis on the former.

What say the collective?

I striped mine both sides and used DynaMat plus the 914rubber one shown earlier, keeps the heat out but I add Webber to my 2056 and drive mostly with the top off,, Ive got lots of good sound.

Posted by: carcus Sep 1 2016, 12:43 AM

Thanks all. I think I might go with the 914 Rubber one.

Any one try a spray on sound deadening? ( Lizard skin or the likes)

Mine also had surface rust underneath it on the passenger side. I ended up just using dynamat on the inside and dumping the engine compartment one. It also gives me more clearance to get to the 914-6 fan belt.

I had holes that needed to be repaired on both sides of the firewall from moisture trapped by the factory pad. It's gone, and I used GMat on the inside under the backpad (and the rest of the interior). It worked well. I still have plenty of engine sound, but I can hear the stereo too!
