Has anybody installed a noisekiller soundproofing kit?

I'm considering installing a soundproofing kit for my Bongo. It is made by noisekiller.co.uk, and they have a kit specifically for the Bongo. Has anybody on this forum bought one of these? -- I'm curious as to whether the centre bit between the front seats with the AT gear shifter has to be removed to install the 'engine blanket' part of the kit (which looks like it would be a pain to do). I'm also curious about whether the engine blanket would create a build-up of heat under it. The blanket is lead sandwiched between layers of acoustic foam.

In my opinion, the Bongo is fairly quiet for a van -- but watching DVDs or listening to music without turning the volume up quite high at 60+ mph is more difficult than it was in the cars that we've owned. I know I shouldn't be watching DVDs while at the wheel but...

Anyhow, I'd appreciate forum readers' views on the merits of Bongo soundproofing.

Funny you should say - I was looking with interest at their stand yesterday at the NEC - seems like a great idea, and I think I may well go with a kit - couldn't believe they catered for Bongos - there really must be getting popular.

I also asked them about heat retaining kits or material for putting under the interior panels, stuck to the metal sides. They said they can supply a needle-woven self-adhesive material called ANG3 - although they couldn't give me any prices for it, as they supply it to motorhome manufacturers - but it sounded ideal for the Bongo.

My experience of the Bongo, such as it is, is that wind noise (partly due to the sidescreens I suspect) and road noise esp. over bumps are the main culprits. In the cruise at 60-65mph the engine is surprisingly quiet considering it is situated right under the 2 front seats. What do others think?

I agree Mike - I wouldn't bother with soundproofing. I quite like to hear the engine so that you can hear if something goes wrong, and I don't find mine particularly noisy.

I think any soundproofing under the cab is going to be difficult, and as for the back - i'm never there when I am driving so who cares!

Seriously though, there is merit in insulating the van if you are using it for camping, and there is plenty of space behind the rear panels to give a decent insulating layer.
I was at a show recently talking to a rep from 3M. He was showing me 20mm thick 'thinsulate' as used by many of the big names. Its basically a blanket type material without the itchyness of traditional insulation. The idea is that all the pillars etc are stuffed with the offcuts so there is little waste and good overall insulation.
Not sure how easy it would be to do the front door panels without affecting the windows, but sure its possible.
Incidentally there is a post on the vw forum, they recon that just waxoiling a panel does quite a bit for sound deadening.

I lined the side panels and door skins with 3M bitumen adhesive pads.
They stop the panels from "drumming"

I had a kit from these people in my first Landie which had a very noisy 200TDi engine and was basically a commercial vehicle with no carpets at all.

Made a huge difference. But I can't see the need in a bongo, really - I guess you can always make a quiet vehicle a bit quieter. Diminishing returns, I would say.

I agree that the Bongo is relatively quiet, but my 6 year-old doesn't think so when sitting in the middle row. It may be that she has much better hearing --I knew I shouldn't have gone to that Motorhead concert...

Noisekiller quoted me £175 plus £9 shipping (or 'carriage', as they called it -- from this I assume the kit will arrive in a horse-drawn carriage, a very quiet one). I wonder why they have two prices for the Bongo kit?

The fact that noisekiller even make a kit for the Bongo surprised me also -- it suggests some demand.

When was that quote?

I got the quote on Monday -- and just as I was posting my last message a few hours ago, I got an e-mail from Noisekiller apologising for giving me an incorrect quote -- it is £190.

Thats a lot of money to insulate around the engine - it does sod all behind the engine, so your 6 year old will still moan, just that you will be able to hear him better !:lol: .
