Installed the Frost King sound insulation on my 2001 C5 over Memorial Day weekend and am VERY HAPPY with the results. I used 7.5 rolls and included rear wheel wells, rear well liners and from the rear tub all the way to the front firewall and tunnel area. Then used 10lb 3/8" foam carpet pad for the driver and passenger floor area (not the tunnel but maybe could have - dont think I need I it) up to the shelf behind the seats. I cut the foam in two pieces where the floor and the riser behind the seat meet. Used plenty of aluminum tape to tape the seams and with FK there will be a lot of them.

FK worked great but was very time consuming to install. Take it easy on the 3M adhesive glue as the odor is not good. I understand that there is new spray now that is oderless and wish I had used that instead. I bought the FK and the 10 lb carpet pad from Menards. I used the oem carpet sections and a sharpie to trace out the padding and cut out the slots for the seat wiring and for the holes to the floor where the seats bolt in.

Whole project took about 24 hours by myself but the sound reduction from road noise is considerable. Easy to now have a conversation with the wife or listen to the radio or use the cell phone even though I'm still running the the oem runflats (which are over due for a change). Many thanks to all of the posters out there on this subject which gave me the info I needed to pull this off. Especially Mike Mercury's posts.

BTW, I hope you all sign up to be organ donors. Im coming up on my three year anniversery and wouldnt be here today with out the new parts. God bless.

UPDATE: I just performed a decible test on my c5 and here are the results:
65 DB at idle in garage
72 db at 40 mph - asphalt road in good condition
77 db at 65 mph = concete expressway

According to what I've read, the stock DB at idle is 87 and the DB at 65 mph is 93 (if my source info is correct). I down loaded a software ap for $7 bucks for my iphone from the ap store "SPL - Sound Meter". I was introduced to this ap by a person who sells sound equipment and was told that his engineers took the iphone and this ap in their testing lab and said it was spot on. I ran the test with A/C and radio off and for the highway test I set the cruise control for 65. Naturally the DB goes up with acceleration . My car has a 2001 Z06 exhaust but is otherwise stock. As a reminder, I installed Frost King in the interior as well as the rear wheel wells and even some on the rear well liners. I also installed 3/8" 10 lb carpet pad on the floor and riser for driver and passenger and am running on brand new General UHP tires.
I would think that from now on anyone wishing t oknow the impact on road noise should be able to duplicate my results if the work done and tires are the same. I would think that anyone selling sound proofing should be able to shell out $7 bucks to provethe value of thier product.

Enjoy.

 

Well first, congratulations on the successful transplant......
Second, congratulations on the soundproofing job...quality time with the Vette... Did the back and wheel wells on my Z and it was time well spent.....Now rest up and on to the next mod...

 

I need to do the same thing. I did the entire rear a while back with Dynamat when I had a system. I think I will leave that and do the front in FK.

Congrats on a successful self-mod. It's always the best kind.

 

INMHO i'd do the rest of the vette in dynamat just my .02 though

Is dynamat a better sound blocker than FK, or other mods? It's certainly expensive enough.

 

Dynamat is better than frost king, but is heavier and way more expensive. I just finished a weekend marathon of sound proofing with the Crazy Cowboy pre-cut kit (along with fixing the rocking seat and running wires for future subwoofer). I looked into Dynamat, but the price is prohibative. Maybe in the future. I also used some heavier foam with some kind of rubber layer on it. It is heavy as crap, but killed the drone from my BB exhaust a little, which is what I was looking for. After driving around a bit, I think I am going to add more Ensolite to the wheel wells as I am getting a bunch of road noise from that area. I may just double up in a couple of places with the Frost King also if it works that well.

It's amazing that it only took 24 hours. This sounds like a very labor intensive project. For us newbies....what kind of work is involved? Is there another link (with pics) that provides the detail?

 

Hi There:
Check out the price for dynamat on e-bay.

It's actually not that hard at all, just tough to get it all cut perfect. The entire interior comes apart super easy. All your real time is spent rolling out the matting and getting cuts and angles lined up to do a quality job.

 

I recently did a similar job on my car.
I was hesitant at first, but things turned out well.


If anyone is contemplating doing it... go for it!

 

I did mine in about 4 hours but that also included the rocking drivers seat repair while I had the seat out. It made a difference.

 

Are there any step-by-step (best order) instructions for this upgrade?

 

absolutely it's better. But the drawbacks are the higher price and it weighs a lot more.

If I wasn't so cheap - and weight conscience (was trying to break into the 12's) - I'd of went with Dynamat Xtreme, Quite Zone, Dead Zone, Drown Bread, or similar product.

FK works well for the price and low added weight; but there are other products out there if cost/weight aren't a concern.

The FK is already adhesive backed what did you use the glue on ?

 

heart, kidney, liver, lung?

Mike, I used the spray glue on the riser behind the seat and also some on the wheel well and whell well liners. The smell is toxic and gave me a headache so I've been parking the car outside for a few days to air out. Smell seems to be gone now and the lack of road noise is great.

Regarding the transplant - I had bilateral (double lung). Doc told me in Dec 05 that I was at end stage lung disease, lived a full life (at age 52 and 10 mos) and had 1-2 years tops to live unless I got a transplant. I went through the evaluation and had my new lungs about 6 mos later. Never smoked but had a degenerative lung disease call bronchiectisis which is similar to cystic fibrosis. Im told that they only do about 800 lung transplants in the US per year so I know that Ive been really blessed. It's Crazy to bury perfectly good organs when people are in hospital beds needing the parts. Dont take your Organs to Heaven - Heaven knows we need them here. Please register to be an organ donor if you've not already done so. You can make your passing a blessing to others. Thanks for asking.

 

sounds like you're doing well.

This July will be 29 years post kidney transplant for me:

Great job on the insulation.
Really wonderful to hear about the transplant. My step-father was diagnosed with Alpha-1 almost 20 years ago. He wasn't supposed to live five years without a transplant.

Congrats on getting the mod done. Nice sometimes to have a little quiet time while behind the wheel.

 

I did the FK mod when I installed the new sound system. I was very happy with how well it worked. Good job on your install!

 

Where did you get the frost king, I looked at lowes and could not find it.
