Sound Deadening the G.
#92
To be honest, I don't really know. I never weighed it before. Originally my plan was just the doors and a little bit on the trunk lid, but it spread to the rear deck, trunk walls and floor, rear doors, wheel wells, and the hood. I didn't feel my car being much slower, but I did put on a bit of weight I assume. I think I put on about 2.5 gallons of liquid deadener and about 80 - 100 sq. ft. of deadener mat. The trunk lid had the most layers, but nothing would make it rattle. I had 2 layers of Damplifier, 4 layers of Spectrum, and 2 layers of sludge. Stiff as a rock.

one of my favorite things about the G has been how quiet it is. i feel like sound deadening it would be overkill and just add a ton of weight, although i could completely change my mind in a couple months when my stereo is completed. either way this thread presents some very inventive ideas. props guys!

I painted 3 layers of just spectrum on the front wheel wells and fenders and 2 layers on the rear wheels. 1 layer of sludge of the front wheel wells and fenders and I had quite a bit leftover. Enough to do the top of the rear deck with 1 layer of sludge, the bottom of the rear deck with 2 layers of sludge, the trunk lid with a layer of sludge and still having leftover. It will cover quite a good amount of area, but doing 2 layers of sludge for all the wheel wells or even 3 with all sludge, you should still have some remaining deadener.

So, yeah, the weight does slow it down a bit, but not incredibly so.

I just got my 05 G35 MT as my DD and it isn't fast enough. I'd like just a little more. I would like to quiet it up a bit(mostly a tire problem which can be addressed easily) but not at the expense of performance. 300lbs will slow the car down quite a bit imo.

Correct, could be a bunch of feathers, but 100 lbs in feathers is still 100 lbs. But the amount of deadening isn't overkill IMO. It's annoying to hear little pieces rattle, even faintly. Plus, when it rains, it's nice to have it where you don't even hear it coming down. Only place you would hear it on a well deadened vehicle is the windows, other than that, it can be virtually silent.
I'm not personally into performance, though some people are. It is a sacrifice, but there are other ways to gain back performance...turbo for example
IMO, it's a toss up and really depends on what is more important to you. When I had 200 lbs in my Accord I didn't notice too much of a difference when I downgraded and had less than two thirds that amount. If I went on the track, then I'm sure the numbers will show the difference, but every day driving, I didn't really notice anything, or possibly I got used to it.

yeah I dymamate my two doors and from the rear to the trunk.weight is no big deal to me since I'm not racing my car,but I do have a audio system and it really does sound alot better.it still rattles but not as much as if I did'nt have any dynamate.I heard this one car he has a okay system in it and no dynamate, just sound
dynamate I think while inside your car will improve the music and sound of the system plus lower road noise by a little..

Ok, let me rephrase. I track my car well.
The approximate performance reduction is about 11 lbs to 1 hp. This of course only takes into account straight line performance. However, most of the weight you are adding will be low on the car, so it won't hurt the center of gravity very much, either.
So, that 300 lbs of sound deadening (or audio equipment, or extra body fat that you carry around, or whatever) will cost you approximately 27 hp, or 10% of your overall hp. A fair trade off, in my opinion. Yours is obviously different.

first off, unless you're taking out the headliner and deadening that too, you're going to hear rain. second, it's true, 300lbs is 300lbs, regardless of if it's in the form of bodyfat or stereo equipment, or soundeadening. however there is a MAJOR difference in that the 300 lbs in stereo equipment can be easily removed, and for what its worth, if you have a man with 300 pounds of body fat, he's going NOWHERE fast except in a lear jet, as his total weight would be close to if not over 5 bills.
