Am I crazy for wanting to Dynamat my Vert?
It seems like it would cut down on alot of the road noise as well as keep the sound in. Granted it won't make a big difference with the top down, but with the top up I think it will still make a worthwhile difference. Anyone have any input here?

I'm particularly interested to hear from someone who has actually done it to his vert, if anyone has.

 

I'm no 2nd gen authority, but I did use dynamat to keep my rear speakers from rattling the cover panels. I say give it a shot. It will definitely reduce rattles, but I don't think it would reduce road noise. Just my fifth of a dime (.02$)

 

I would agree that it won't have much impact with the top down. It will have a major impact on the body panels that are not already treated.

Which product are you planning to use? and where?

I have authority by the manufacturer to distribute Dynamat products to car groups on the internet. If you would like a quote, let me know what product, and I will work one up for you.

That **** is heavy and the verts are already the heaviest 7s in the bunch. Why add more weight?

 

It's just road noise, who cares? As far as keeping the sound in, it's not like you're creating a concert hall in there. Like 605 said the vert is already a portly FC, and it seems like a lot of trouble to go to just to insulate a few Db.

 

Still looking for info from a Vert owner....

 

It would have many advantages, even to a vert.

- Better insulation,helps keep hot/cold out
- Quieter car overall
- Less interior rattles
- Creation of a more "solid car" feel
- Better resale value (due to lack of rattles and quiet drive)

As far as material, I beleive dynamat to be far overpriced compared to similar product available. I have used many sound insulation products including dynamat, but so far the best bang for the buck is Edead:

See their website here: http://www.edesignaudio.com/ep/edead.htm

I also recommend a spray type insulation for those hard to reach places:

Hope that helps

 

has anyone added heatshield on top of the area above the exhaust in a vert?
my 88 radiates a LOT of heat from that area.
any advice on what I can apply...

TIA

I used Cascade on my Vert and it made a big difference in cutting down the road noise. The area behind the seats, where the spare is stashed seemed to make a big difference. I chose to use Cascade because less weight, like the vert isn't already a tank, no fumes, and it won't burn.
I think you'll be glad if you use any of the sound proofing out there.

 

Good advice.

For those touting the wieght issue, do you seriously think that the amount used would seriously amount to much? You could make up for the weight by adding a few HP anyhow

 

That stuff will not make the car "more solid" it adds no chassis stiffness. That stuff is also like ten pounds a sheet. If you line a good amount of your car you could be looking at 60lbs or more. True that is not a lot on the grand scale but it could be like driving with a passenger all the time. 60lbs is a guess on the conservative side it may be more. Yes more horse power would help.

 

I think he meant that a car that is "solid" doesn't rattle...not chassis rigidity.

 

The amount of weight gain you guys are quoting is nowhere near that high. I bought a 40 sq. ft. roll of that edead for another car of mine and the entire package weighed a little less than 15 lbs. Granted, if you were to apply 40 sq. foot of something like dynamat extreme you'd be looking at a little more weight, but nowhere near 60 lbs. Keep in mind, the 40 sq. ft that i used coated an entire trunk once over and twice in some spots....i couldn't imagine a vert using much more than that. I'd say that you can't go wrong with using any kind of sound deadening material..whether it be for audio purposes or to just quiet road noise which it is very effective at doing. I've had both dynamat extreme and the edead and i'd say that for the money the edead is just fine...but its not dynamat, not by any stretch.

 

Or, you could skip hamburgers and eat salads for awhile. Another though at how to reduce car weight.

 

Weight gain is only 20 lbs.

That's alot of dynamat extreme too.
Since I'm going to have to pull the carpet up in spots to run wires for the sound system I figured I might as well do it anyways. Someone told me there was like a coating of stuff on the metal beneath the carpet??? When we did my friend's interior I didn't see any?

Anyways, main objective of this post was to say that the weight is not a big deal.

 

Exactly. If you've ever driven in a FC that is rattle'less, whether or not the car is more solid structurally or not, it SEEMS more solid and better built. Just the way cars work.

 

there is no coating on the metal in the floorboard of a vert, there is padding on the carpet, pretty thick padding at that.

 

Sorry I must be thinking of a different kind or band of dynmat, because the stuff I saw came in sheets of 1sq foot and the box of 5 was about 15 lbs. Yes I too have a lot of rattles and noise from my 2nd gen. Good luck on the noise damping. I will leave you all alone now.

 

I have the "dynamat super" (with the silver foil on it) in the trunk area of my 89 t2. Probably added about 10 to 15 lbs. I didnt notice any difference in road noise, just that all the rattles went away. Also, i found the dynamat super (if thats what they still call it now) is much higher quality than the regular dynamat. It conformes to irregular shapes better and the glue backing is much stickier.

I would say dynamat is more for stopping rattles than drastically reducing road noise.

I know someone who had a old tacoma truck that had a huge stereo in it. To cut down on road noise and rattles, he put plastic "skins" inside his door and filled them with super expanding foam (not the 1:4 kind at home depot, stuff that expands much more). It made his doors tight as a drum and really quieted stuff down. Plus there is almost no weight involved with that. Just something that i thought id throw out there.....

I can't remember the name of the stuff, but saw a hot rod show a year or so back that they used a ceramic paint (I think). Anyway, the stuff was like twice as good as any mat you could use as far as sound deadening and heat reflection -- plus you could put it anywhere you can paint, and much lighter. Lot of hot rodders will paint a frame-off resto -- basically any bare metal they can find that won't have colored paint on it (i.e. covered up by something).

I think it was a bit pricy, but prolly worth it based on what they were saying.

Sorry for being so vague -- I'll try to do some searching, but maybe someone knows what I'm talking about.

 

Dynamat more or less will quiet rattles.

If you want more sound deadening, the best way is to spray a rubber undercoat across the bottom of the car and in the wheel wells.

Theres not a whole lot of room to quiet an FC down more since they are actually very queit and well insulated cars in the first place. But every little bit helps.

 

So.........

The insulating coating that is on the floor, firewall, trunk area, and rear wells in a coupe is not in the vert?

I took about 20 pounds of the stuff out of my race cars.

Very interesting...............

I pulled the carpet back on my 88 vert behind the drv seat, and I could see the bare metal,


on my 90 gxl, it has more insulation and hence less heat conduction from the exhaust pipe from the area in between the seats
