Holy Dynamat.

bam-a-lam!

You don't have to remind me :(

How much weight do you think you have added?

The factory sound deadening I took out weighs about 50lbs

Assuming I use up everything I have:

2 boxes Dynamat = 44lbs
2 rolls Dynapad = 30lbs
5 rolls of Dynaliner = 10lbs

Total = 84lbs

I expect to be in the 70lb range when I am done as I will not be using all of the Dynamat Extreme sheets, so it would be an extra 20lbs of weight compared to OEM but I end up with much better sound and heat rejection.

I'd pick Betty, too. Veronica looks like a prude bitch.

Now that I have some extra Dynapad in hand I chose to recycle the pieces and use them in the hatch area instead of 1/4" Dynaliner.

This will help a lot with reducing the exhaust noise even more and I save $$$ since I can return the extra box of Dynaliner I won't be using now.

So we begin with my favourite chore of making templates.






The passenger side footwell piece trimmed down fit the width of the left hatch area, but it was too short, so made another template.






Now to solve the spare tire well… I was happy with the end result.

[MC Hammered]

The Dynamat does get warm to the touch as it absorbs the heat from the transmission tunnel so I will be installing a layer of 1/4" Dynaliner to act as a thermal barrier.

I am trying to keep the seams between each piece as tight as possible.









Both sides completed and I used one roll of Dynaliner






Test fitting the OEM carpet to make sure everything fits with the new products installed




Unfortunately the OEM carpet does not fit back in with the front pieces of Dynapad installed. The foam on the OEM carpet is molded so well that the 1/2" of extra material prevents the carpet from seating properly.

I did anticipate that this may happen and that is why I did not use any adhesive to attach the Dynapad to so the pieces for the front driver and passenger side footwells were removed.

Wow that car is going to be silent on the inside with that much sound deadening. Nice work!

diggin the rides man

Starting on the hatch area where if you rap the metal with your knuckles you can just hear the metal ring.





One of the worst vibrating parts is the bottom of the spare tire well.

I didn't want to use multiple Dynamat pieces for this so I made a template to maximize the coverage.





Hatch area done and next step is to put Dynaliner in the spare tire well and Dynapad on the upper flat surfaces.

Rear seat area done and taped up




I chose to use Dynapad in this vehicle to help block/absorb noise. It is a sandwich construction of foam and heavy vinyl material.




Making templates and cutting the Dynapad





Pieces fit together perfectly and they are heavy so they just lay there.

Total Dynapad used for the front & rear footwells and the rear seat top is 1.5 rolls.

Today we start doing the driver side of the car… just like playing Tetris



The driver side layout is not as pretty as the passenger side but it gets the job done.

This is how much one sheet of Dynamat Extreme will cover




Finished with the second sheet




Starting the front console section



As I am rolling around I realize the butyl is squeezing out of the edges of the Dynamat pieces and sticking to my coveralls… the butyl is nasty stuff and isn't going to wash out so I decide to start taping up all of the seams with aluminum tape.





Front driver seat area all taped up so I can move around in there again without any more issues



Front console section done with Dynamat





Now all taped up






Front driver section completed



Working on the rear console section




Now all taped up





Driver side section all completed.. I probably have the same amount of aluminum in my car as a Russian satillite.






Taping up the passenger side before calling it a day





Everything done today took 7 hours, I used up 6 sheets of Dynamat and have 50% of the car done.

[MC Hammered]

There is nothing like necessity to light a fire under your ass and get things done… a dose of procrastination from doing any more work helps a lot too.

So while there was some light out I decided to start installing some sound deadening into the car.

The sound deadening products I have selected are Dynamat Extreme, 1/4" Dynaliner and 3/8" Dynapad. For the doors I will use 1/8" Dynaliner to replace the vapor barrier.

Here are the high tech tools for the job



Some people like installing the Dynamat in big sheets, I prefer to cut them down into smaller pieces and them fit them together.




If the pieces line up then that is great, if they don't I won't let my OCD run out of control since this much Dynamat is overkill anyway.

So this is how much one sheet of Dynamat Extreme will cover




Sometime you just have to make a hole




The sun has set, the temps have dropped as I can feel the Dynamat harden up. Two sheets took 90 minutes to install and the J-roller does come in handy making the sheets conform to all of metal.

This is how much two sheets of Dynamat Extreme will cover.

Since I have an s52 swap, unless I lower/drop the engine, I am unable to extract the blower motor in order to put some sealant over the deteriorating 20 year old seal.

If water can't get past the driver side grill opening then the water leak problem is solved right? So I decided to seal up the drive side grill.

First I had to flush cut off all of the little plastic nubs




Sanding them down smooth



Using some cardboard to make templates






I used an old vinyl chequebook cover for the waterproof barrier








Pulled out the tube of PF224 sealant, spread it all over the vinyl piece with a plastic knife and put the piece in place and let it dry.
