The biggest source of noise is undoubtedly the engine. Mainly because it's right behind your head. You can dynomat but in all honesty it'll still be noisy. It's something you get used to.

 

I Dynamatted mine and it helped... I also bought a new, thicker dead dog from rimmers and that helped too...

Still not quiet but at a steady 60 it is fine

 

Thanks for that. I'll have a look and see what I can find. The engine noise I can understand and live with it's more the road noise and general clattering of the car.

I went in someone's MGF a while back and I'm sure it wasn't as noisy, I would ask him but he was no MG expert and doesn't have the car anymore.

 

if its the clash and clatter set the VHS Bilstein setup on normal springs.. improves the crash no end!

 

With a hard top on in the winter, my TF is noticeably quieter (inside the car).

 

Totally agree with this. Pretty much all noises are reduced by a hardtop:-

The engine cover section behind you is filled with the hood that quietens the engine.

The window seals better and reduces wind/road noise.

The hardtop is better insulated, also reduces wind/road noise..... even improves acoustics.

Dynamat is good, especially applied to the doors inner skin. Builders flashing is pretty much the same stuff as Dynamat but works out a little cheaper,

 

Dynamat Extreme

I've just covered the entire floor, forward fire wall, and rear fire wall (including the engine access cover) with Dynamat Extreme and then Dyna Liner sound proofing. I'm waiting to remove the door skins and will also line the doors with Dynamat Extreme. One trap for new players is the fit of the OEM carpet, especially in the foot well and accelerator pedal with all this sound proofing. I may end up removing the Dyna Liner from the drivers pedal area due to interference. I haven't driven the car as the SCU is in the UK being refurbished but I will as soon as it comes back to Oz, and modify the lining accordingly. I expect (hope) that the road noise will be quite a bit less.
Best wishes fellas.

A hard top is the best sound proofing as most engine noise comes out of the boot lid grille and straight through the hood/plastic window. The more solid hard top and it's glass window significantly reduce this noise. It makes the car like a tin-top! No other sound proofing will do that much but may reduce harshness due to damping vibration of panels and doors,etc.

 

I used a dynamat type product on every exterior panel.. Applied with a paint stripper gun.. (Heat the product up until its near melting)

Also did the entire inside of my cabin.. (Complete interior stripped) every inch of metal

Both sides of the fuel tank cover

Inside the fuel tank area (tank removed then re-fitted)

Inside the engine bay

Inside the boot

Then applied 10mm closed cell foam over most of the areas on external panels

Then foam fitted all of the rear wings with fire proof expanding foam to reduce the engine noise in the car

Engine cover will be double glazed Lexan cover

I've spent about £1,000 sound proofing my car because I plan to do long Euro trips in it and want it as quiet as possible

My car sounds like concrete when you tap the doors/wings now..

No idea how quiet it'll be yet though as it doesn't drive yet..

Quite possibly the most extensively sound proofed F/TF yet..

 

Has anyone else done something similar to good effect?

Not interested in a hardtop only the hood down driving experience.


Cheers

Mike.:wink:

 

I'm also fitting brand new carpet.. New underlay and all new door rubbers..

Better not be any wind noise when I drive it!!! Lol

 

I don't have a hard top yet, but if that will help through the winter then I'll definitely get one. Again, any experiences?

I found no difference in noise levels with the hard top.
Don't get a hard top unless you really really need one, I kept mine for one winter and got rid of it.

 

When I soundproofed mine I noticed that when I did the wheel archers inside it made a difference I also did the floor, behind the seats and engine cover but the wheel archers made the biggest difference

 

I'm not sure what you mean with the wheel arches - isn't most of the wheel arch either under the bonnet or in the engine compartment? I have done the boot but haven't bothered with under the bonnet. I didn't want to add any where it was visible.

 

Dynamating everything, will give 100kg more?

 

That is the downside-this is quite heavy stuff.

 

Aside I'm completely bald, not by choice...

I agree that the car can become "noisy" in the wrong sense.

So, I think a bit of dynamite is critical places is a good thing.
Probably I would not do it capillary :wink:

I have considered this several times with my car too...
