how much deadener?

[BarnDog296]

I am working on putting sound deadening material (like dynamat) in my car, and I have NO idea how many Sq ft I need to do this. I have an S13 Fastback and i plan on doing the ENTIRE floor, from the firewall to the trunk and all of the doors. Has anybody done this can help me with a rough estimate for what i need (more is better)

Alright, since no one seemed to have an answer for this, if anyone else is going to do this, they may want to know.

You are going to need about 100sq ft of deadener.I did my ENTIRE hatchback with 100Sq Ft. and in the trunk, I put 3 layers for the exhaust. If you have a LOUD exhaust, you are going to a need sound dampening material as well. I used B-quiet, but I have a 3" exhaust on an NA/KA and its LOUD AS FUK! so i need some lead dampener now. I DEFINATELY recommend B-Quiet, it is amazing stuff.

buy their stuff, specially when they sell it on e-bay, which they do alot.

Thanks for letting us know. I have actually looked at the B-quiet stuff before and wondered about it. How much weight did you end up adding to your car in the end? I have really been planning on lightening up my car, and I wouldn't want to add too much weight back in, ya know.

I didnt feel like it added much weight at all, but its about 35lbs for 100sq ft and i used it all. its like .35lbs per square feet just take that number and multiply it to figure it out, but i did my ENTIRE car in it. I thought the 35lb add was worth the noise drop.
