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! |

Thanks! I think it helps, that's my subjective opinion, I drove it some after putting motor back in but before the new outer pad and inner pad went back in. I have the 914rubber.com new pad in engine bay and the stock rubber pad on inner firewall and then of course the back pad which is a recovered but original back and foam. fyi my car also is a 2.0L, d-jet with back dated SS he and Triad muffler dual out exhaust. has a nice sound with acceleration but is pretty quiet cruising on the highway. at one time I had achart with decibel levels I took with and without top on and with and without the pads, etc but don't remember the numbers. I can tell you the Monza muffler that had the quad tips on it was horribly loud and more raspy, like those ricers and suby cars with their bad loud raspy mufflers. anyway, I don't tire of the sound of my system it does not get on my nerves.
