I have a Ford Transit (2005 2.0 diesel) which is unpleasantly noisy to drive in compared with my Ford Focus (2003 1.8 petrol). I want to install sound proofing in the van, but I am wondering if this will get it anywhere near as quiet as in the Focus.
For example, if the Transit simply does not have soundproofing foam or vinyl in places equivalent to the Focus, then I can install it and be happy with the result.
On the other hand, if the engine in the Focus has, for example, an engine mount designed to reduce sound in the cabin, then clearly I cannot hope to match it in the Transit.
So my question is, will adding foam and/or mass-laden-vinyl to the Transit get the noise levels down to roughly the same as the Focus? Or is there a major structural aspect which I cannot hope to overcome? (Aside from the shape of them which is obviously different - not that I think that would make much difference?).
