Noise levels for a 2.0 L FI set up - interior vs exterior padding Options

[Tdskip]

Good morning, hope everybody’s having a good week so far. I know that from the factory there was padding in the engine compartment as well as having an interior back pad. My question is if I put additional sound deadening on the inside and then the back pad is that roughly equivalent to the sound pad that was in the engine bay originally?

I’m sure not having the pad in the engine compartment does lead to increased noise, but not sure how dramatic of an increase that would be with a fuel injected car.

I know this is a subjective topic, but looking for experiences and thoughts if you don’t mind sharing them. I’d like the car to be civilized and usable for fall day driving without feeling overly fatigued ( which I am comfortable doing another vintage cars and don’t feel the need to have a modern vehicle to do ).

Thanks!

I have not tried this. But since the dynamat is a tar type bonded to an aluminum backing, could you paint over the dynamat ? sanding it and treating it as an aluminum panel?

I have the Dynamat all over the interior under the carpet and backpad. nothing on the engine side though.

That is exactly what I did. Not Fat Mat, but Noico. Same thing just less expensive. I etched the aluminum face with phosporic acid then sprayed with reduced epoxy primer and then top coat. The result looks very close to the factory tar. You can read the whole process here: http://www.914world.com/bbs2/index.php?s=&...t&p=2659673
