This is me, picking up my freshly repainted 914 from PMB Performance.
Now that it's home, it's time to start putting things back together. I'm looking for sound deadening solutions for the floor and interior back panel. I'm planning on keeping the interior back panel, but figured this would be a good time to enhance it with some sound deadening capability. My searches haven't been very successful. I'd appreciate it you guys could offer some advice or point me to previous threads on the subject. |

I have a roll of Dynamat for my car when it comes together. If I recall it is about 1/8" thick of a semi-sticky black tar-like substance with a heavy foil backing. No odor no glue required. Just cut and using a smallish roller lay it out and roll it nice and smooth and flat. I like to color and the paint job looks to be top drawer.

I've used FatMat on several cars over the years with terrific results. It's virtually the same as Dynamat Extreme without the high price.

I have these two options on my list.
Sound deadener (Heavy) 50 Sq Ft Noico Self-adhesive Foil & Butyl Mat 50 Mil (Same basic product as Dynomat, however much cheaper and in easily workable squares) NOTE: They do sell this in 80 mil, but state that the 50mil is the best weight to results. http://www.amazon.com/gp/product/B00URR4O5..._dp_o_pC_nS_ttl Heat/sound barrier (Light) EZ Cool Automotive Insulation http://www.lobucrod.com/ Basically i'll use the Sound deadener sparingly on large flat panels and over gaps to help deaden the tinny noises. I will cut small strips and place them on every piece of metal to make it more "heavy". From there I will use the heat/sound barrier (lightweight) over that and create a full barrier as this will be my total seal, doubled up at the engine firewall. |

+1 on the FatMat. A lot cheaper than DynaMat and just as good.

I used a 50sq ft roll of 80mil on my 914. Made a big difference . Bob |

Lots of good info here and online.
My two cents. Sound deadening is about stopping both sound waves and vibration. Certain materials stop certain sound waves. Product like dynamat at rubber-foil which blocks two types of sound waves. It also builds up the thickness of the metal to reduce vibration. I would suggest a multi prongs approach. Ceramic spray on sound deadened on the engine bay side.( lizard skin is on product) 1/2 inch foil faced mat on the engine bay side (914 rubber has that) Dynamat on the inside. Then both blocked more types of sound waves, but reduced vibration twice. After all of that, the window is really loud. A double pain would fix that.. In the end, a loud stereo or earplugs work really well. |

I wear these on the highway when I have the roof off and the windows down (which is usually all the time). Really cuts down on the fatigue factor on long trips.

Hi Ernie,
Just had to say hello and the car does look great. It has been a couple of years since we moved to Oregon. I have used Dynamite and the only thing is that it is expensive; I believe I will go the Fatmate or what Andyrew suggests. I personally want to stay away from the spray ons since over time they appear to collect rust. Underneath I have used rubberized adhesive paint. Again, the car looks great. Steve Hurt |

Even if it would be helpful, no treatment on the engine side for me. I just finished paying to fix rust in the firewall so we're not going there again. I have pretty reasonable expectations of how quiet a 914 can be so I think I'll be fine with interior treatments only. |

Earplugs, like Elliot said, work wonders, especially on the highway next to trucks.

Your car looks great! (IMG:style_emoticons/default/beerchug.gif)
I went with Fat Mat Rattle Trap and installed an aftermarket heat/noise pad from 914 rubber (that won't hold water) on the engine side of the firewall. I am very happy with the noise level in my teener: http://www.amazon.com/FatMat-Self-Adhesive...rds=rattle+trap |

I suggest not one huge sheet on the floor boards. Leave the channels on the floors open, so if moisture collects in them, it can dry out.

I used the same as CAIRO (Dynamate), it is very easy to work with and dampens any vibration I was having. And yes my dynamite came with a handy roller. I used heavy 2" AC foil duct tape at the seams and it really came out nice. I like you choice of color. Nice car. Mike |
