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!

Havent seen it mentioned yet so ill bring it up...

I have quite a few 914s but the one that has the factory undercoating is by far the most quite/comfortable ride. With or without the engine pad in.

Not a popular option due to the rust potential so a lot of people strip it off, but a noticeably different experience. The car has a much more "high end" feel/sound to it and less like im rolling around in a tin can. Curious if other with intact undercoating have noticed similar?


When i ever get around to stripping another one for paint I want to hit the entire pan of the car, and interior firewall with lizardskin to see if i get similar results.
