Not a 'traditional' ecomod, soundproofing!

Why? We all know that the biggest mod is adjusting the nut behind the wheel - with new cars the mods are few and far between. If the nut behind the wheel has an easier/ more comfortable time behind the wheel, they're likely to get better results.

A quieter cabin is more pleasant. A stripped out race car might be lighter, but it soon gets tiring, and a tired nut soon loses focus.

So I've added a bit more comfort, I sound proofed my doors. The floor already had really thick (almost 1") of foam on it. The difference is noticeable but not night and day.




I've done a few cars now. I've learned that even though today's doors are really tricky, using as few pieces is still the way to go. Aluminium tape seals the edges to prevent them pealing and creating sound paths.

I also added a little mass loaded vinyl to the door skins.

Any economy lost to weight is likely gained back by improved thermal insulation:

Comfort is king! Two cents of tartar sauce could save us millions in productivity.

Radio on mod while cranking mod:

https://ecomodder.com/forum/showthre...tml#post578648

I also added a switch while I was in there so I can enjoy solar powered radio all day. Modern cars won't let you listen to more than about 20mins as a battery protection feature.

I had some Sony speakers bought on sale for another car, but decided to leave that car alone. I was really disappointed that the new van only had two door speakers, not even tweeters! The old model had dash top speakers (not really 'tweeters') and even the much cheaper Renault Kangoo I had before had tweeters.... So something had to be done.

I thought I'd share my install as I think it's quite clever.

The new speakers were slightly too small, I hate the idea of MDF spacers (MDF really has no place in a car), nor did I want to wait for ABS spacers that still might not fit. I also hate cutting factory wiring on even the oldest jalopy.

So, I cut the speakers







The old speaker becomes the new speaker spacer. Don't have to drill out the rivets. The new speaker connects to the old speaker terminals, so all the wiring is intact. Only need a small hole in the speaker spacer to run your wires through, foam sealing tape and screw in the speaker.

Didn't get a pic of the finished job, but you know what a speaker looks like.

I used Milliput:



To reshape the tweeter mounting cups to fit my sail panels. I thought a textured finish would look more OEM, but the truck bedliner I had was too rough for my taste:



So gloss black it is, matching the vent rings:



Carefully chosen music assists my hypermiling.

Onto a more traditional mod, a wiper delete

I hate rear wipers, there's absolutely no need for them on a street car in Australia. Maybe on a flat rear screen like a Prius they still have some value, but not on vertical van rear windows.

The Traffic has twin doors, so it has twin wipers, but the wipers aren't mirrored, which would look better, but instead the look like this:



All they really do is add weight and make cleaning more difficult. Because they're in sheet metal, simple rubber plugs weren't really an option.

I chanced across stainless steel blanking plugs for kitchen sinks. They're available in raw stainless, or white powder coat. If you plan on painting them, go for powder coat. You'll get better adhesion than etch primer on stainless.

Since powder coat is a plastic, I started with adhesion promoter, then primer, and finally colour, the turned out like this:



Although they have a rubber backing gasket, I still wanted to protect my paint (should I ever want to fit the wipers back or it I find smaller blanking plugs - these are just a tiny bit bigger than they need be), so I covered the holes in my sheet metal with helicopter tape. This should also keep any water out as only the threads penetrate the tape.

On the inside, I didn't want metal to metal contact either, so I used a big rubber plumbing washer. This further helps the seal and means the wing nut is unlikely to back out.

The finished mod from inside:



and outside:



~2.4kg (5lbs) saved, looks better and the windows are easier to clean

The van is still missing green tires, green steering wheel cover, green dashboard!
Green seat covers, green carpets..
I refuse to believe that it's the greenest, unless if it's totally green.

"Is that helicopter tape?"

"Nah, it's clear, brah!"

Looks sharp. And oh so green.

Genius! I wish I had seen this before I replaced the speakers in my VW.
