Default Engine Sound Pad Advice?

Should called this 'sound advice', anyway - -

I searched for info on the various different engine sound pads out there, but came up pretty empty.

Seems we've all had experiences with this semi dreadful component, shedding its crumbled contents all over the engine bay. As I've now scraped mine clean and was ready for re-install, the one I ordered showed up pretty much exactly like the OEM version. Very light, but that same godawful foam, set for self destruction.

Went online, saw various upgraded versions, heavy versions, 'heat shielding' versions, you name it.

I'm just looking for effective and 'more' permanent than OEM.

Any input greatly appreciated.

These things deteriorate over time. You'll probably have to pull the engine.

Not sure I'd actually replace it if you are not doing concours.

If you live in hot climates such as Fresno or Montgomery, then heat is a consideration. The factory pad does provide some crucial heat insulation as well. It does not block much sound unless you get the heavy one. And still, most sound comes through the floor and the front windows.

I cut the sound inside my cabrio in half with a simple thin layer of felt sound padding from Pep Boys when I did my carpet. The cabs do have an extra layer of fiber sound pad inside the back seat area so your results may vary.

I'd put in the pad and give it a go for five years or so. They are what, like $50 - $60 so it is a negligible expense. Mine will come from Bob at www.appbiz.com when I get around to doing it.

I went with the foil type... kinda ugly, but better looking than nothing. Its gotta last longer than the foam stuff.

I heard some glue strong magnets to the backside of the sound pad (rare earth magnets) instead of that glue so they can easily yank it out again. Once you get that glue off it's difficult to want to do it again.
I am facing this choice as well and was going to try the magnet thing with foil type so I could yank it easily if I don't like it. Was planning on using some kind of plastic stay to give some rigidity to the outline of the pad. I don't trust magnets alone not to bunch up

I worked at the Porsche dealership in 88, 89 and we had cars coming back that were 3-5 years old with sagging problems.

Had a longish talk with Pelican and AppBiz yesterday, and it appears Pelican still sells the OEM, which is super light, but the same foam. AppBiz has a 'sealed' version that won't/can't soak oil though is a bit heavier and I plan to go with that. (I also called Pelican to suggest they add this to their product line.)

Reachme, I read that too and wondered the same, also resisting the desire to respray glue everywhere I just cleaned it off!

AppBiz mentioned using heavy duty peel and stick Velcro which he said is in many of his customer's cars, stuck firmly after judicious de-oiling and cleaning. We shall see.

Thanks guys.

Cool. I sell double sided tape to a couple customers and never even considered it for this.

I always figured that the mat got sprayed with 3M Super 77 contact cement before it got put into place.

That is awesome. Now, Adam..... Can you work on getting them to open up a "Will-Call" window?

No one has measured the sound attenuation by any of the pads made to fit a 911.

The new ones from the dealer are lighter and may well last longer than the older ones.

Yes, it's a good idea to drop the engine every few decades...

I suggest it is not a good idea to reflect radiant heat back onto the engine.

oh man. I had a detailed response all written out and this lame-*** forum logged me out and it was lost.

So anyway, here's a pic that I was going to post about the topic. No way am I going to spend money on a "premium" membership here. lol

Window? They should have a lounge with big comfy chairs or failing that a system like Sears guaranteeing you order will be out in five minutes from the time you arrive.

Are they Pelican or Pelican't?
