Hi,

The original engine from my Beetle will shortly be removed. You can tell how original it is by the diagnostic plug sitting there unmolested and the tar board still in good nick despite its 37 years.

Purists would cry that I'm pulling it all out if it weren't for the fact that it's a Superbug!!

Anyway, rather than stick the daggy tarboard back in, I'm considering other options. What I don't want is:
* More tarboard, because I'm going to be putting carb access panels in the side.
* Stainless Steel firewalls, because I just don't.

What I am thinking of is this:

What are other people doing, or do you not do anything and just have the painted metal?

Thanks

Craig

Hi
as You will see in many car shows...
many people go for the bare metal look..
but its much better to put something in there and dynamat is an excellent product
I did all around and under My engine bay and above the gearbox with the PVE yoga mat type of foam.. and painted it matt black
You cannot actually see it... I do however have the stainless louvered rear firewall piece on there...

If You use dynamat everywhere You will end up with a very quiet car ...

cheers

RELATIVELY quiet car. I think the truth is if you want a quiet car, buy something else, but yes, Dynamat will make it much quieter than it currently is!

Given that I'm going for maximum functionality for minimum weight, Dynamat might be the go.

Doesn't this promote rust?


Craig. I have done the rear parcel shelf area in dynamat. Made a slight improvement. The thing with dynamat is that it's only a vibration dampener, ie it stops the panels from vibrating. If you want the car to be properly quite you need to add additional sound deadening on top of this like mass loaded vinyl.
The engine bay in my Baja however is bare. One less thing to hose the mud off 😂

your new motor will be noisey , so I would go with the dynomate stuff, the new after market vw tar stuff that you can buy for your bug doesn't hold its shape .
and the steel look doesn't stop the noise,
I would also fill your back seat with some foam from Clarke rubber.

Painted steel may look good but lets heaps of noise through. Mine is currently bare because the tar board came loose and sucked on to the fan so it had to go Although I havn't installed it yet, I bought some boat engine noise insulation from Whitworths. It is designed to quieten down inboard motor noise in powerboats. It is peel and stick one side, layer of tar like stuff then layer of acoustic foam then fairly thick aluminium foil on the outside. Looks to me like it might work ok

Foam in the back seat also sounds like an excellent idea. The engine noise without any seat is very loud, so a seat plus foam may well make a big difference.

Thanks Guys,

Yes, the engine bay is only part one. Once the money tree regrows the entire interior will get a refurb with Dynamat everywhere, soundsystem, carpet, headliner, new back seat etc etc etc.

I think that will probably be at the back end of next year.

I just figured it's noisy enough inside already and given the tarboard will be gone and the engine bigger the noise will be greater, so I'd better do something while the engine is out.

So Dynamat underneath, then the hoodliner, then down the track all the extra goodies inside.

The question I have about the marine stuff is whether it also reflects heat. Nothing in any of the blurb mentions it, but in the Dynamat stuff heat reflection is specifically mentioned.

That wasn't particularly a thing I was worried about, as I then put a stainless steel firewall lining over that.
