Build Thread of Roach my 1959 Volkswagen Double Cab - Page 4

VWGuy · 03-23-2012

1776 (forgot the cam, I think 110) dual weber 44's, counterweighted crank, lightened fly wheel, 009 with pertronix ingitor, 75 amp alternator, merged headers, j-tubes instead of heaters. Not super beef like yours, but a solid reliable engine with a little zip and carb overkill.

Sounds like a nice dependable engine. Not a huge fan of the 009 personally, but it'll run better with the duals than it does with the stock carb. My favorite vendor is in Murray, UT. Good luck with the build

Well pretty much done with the engine. Originally it was chromed out, but I came to my senses and tore it down again to replace with some original german tin. After some sanding and some painting, I had a nice set of tin for the build. Here is where it is at today:

The DC will be home Monday and then this thread will blow up!

wow, nice,cant wait to see it finished,i remember doing a bus about 13 years ago, all alpine except the subs,if i recall it had a 7930 cd player ,dd drive seperates, 2 jl 10wo,the subs were in a downfiring box in back ,dd drive seperates in the kicks, yes it took a lot of listening to get them to sound right,but they sure did sound good. the amp was the big v12 four channel,fronts powered kicks and the rear bridged to sub.no rear fill didnt need it once the kicks were right.that was a fun install.thanks for bringing back those memories.happy easter to you and everyone!

awesome stuff

VWGuy · 04-17-2012

Thanks for all the well wishes!

Here's another update. Dove Blue Applied.

Engine picts re-uploaded:

VWGuy · 04-20-2012

Ok more updates!

The Build will begin full swing Saturday. Paint is done.

Now...LET'S TALK AUDIO!!! I am going to lean on you experts especially when it comes to installing the Second Skin AlphaDamp. I'll post some images of the inside of the cab and ask for suggestions for install.

Here is what I have for my audio setup:
SecondSkin alphadamp .060 Dampening
Tsunami 4g amp kit
Tsunami Battery Terminals
Stinger 6-channel Twisted Component cables
Audiocontrol Three.2
Kicker ZX700.5 Amp
Alumapro ALC 5.2 Component system
Alumapro BP-12
Running off an ipod touch with no head unit.

What are your audio goals?

sinister-kustoms · 04-20-2012

There's no better color than Dove blue on a commercial!

Looking GREAT! Can't wait for the install to begin, I need some inspiration to get stuck back into my dub!

No Rattle, low road noise. Solid bass with balances mids and highs. The truck really helps bass resonate, but makes the mids and highs hard to hear. I listen to all kinds of music from Oingo Boingo and Social D to Bassnectar to DeadMau5 and Daft Punk, but typically like bass.

What's with the engine? Did you change anything on it?

You have an opportunity that many people don't have.... A 100% empty car.

If you want low road noise and no rattle.... Deaden at least 25% of the entire vehicle and cover every square inch with some Ensolite.
I envy this.. my ultimate dream for car audio involves two things...
1) Access to every tool i would need.
2) a clean slate like this.

Enjoy.

Do you have ur mind set on speaker location right now?

It's bigger than a stock engine and has dual 44 carbs. The heater boxes have been removed and replaced with j-tubes and it has a merged header. It also has a 75 amp alternator.

What is ensolite? yeah, The sub box will fit exactly in the space behind the rear bench. Speakers up front will be in some custom pods.

As per above here is a chance for you do this right. Allow me throw in my 2c but lengthy peice of advice.

Lets firstly allow to have a comon understanding in tha there's a few types of different noises. 1. Mechanical, ie the engine, gearbox, heater fan, etc. 2. Resonant panels/surfaces. ie the skins on doors, quarter panels 3. Road noise, ie windm, tyres, air entering/exiting car.
Next we simple need to accept that noise is air, stop the air, stop the noise.

There are generally two ways to go about making a car quieter, ie cover every surface in the hope it captures every possible rattle. OR find them and trear individually.
I think your better off with the second option. So here is my recommendations

I would set up a temporary subwoofer in a box and have playing loud whilst you listen for rattles and shakes, vibrating panels, both inside and outside of the car. The idea is, shake and make the car noisy now with a sub to try and find the rattles. You can do similar by taking it for a highway drive whilst some one else drivers you can feel/hear for noises.

Either way, however you start "making noise". When you find an area that is making a noise, put you hand/fingers on it, if it stops vibrating/making noise then you will know that that is an area you need to treat. Generally speaking, stick on deadners add weight, meaning more energy is needed to shake that panel, because now it is heavier. Your doing the same thing with your hand. Your turning one form of energy into another. No need to cover every single area, just the ones that need it. You may decide you dont want to cover that rear quater near the engine, but you may want to treat it too.

Once every rattling panel is cured, both inside/outside. You would do well with covering the large flat areas of the cabin, ie roof, front wall, back wall and perhaps floors and doors with a foam, the foam sit between the panel and the trim. The idea is to trap air in place, in the foam. This layer of trapped air works well at helping reduce noise. Many modern luxury cars have similar. There are several companies that sell such product.

Next, how many "holes" do you have to the exterior? Even little holes can let in noise in different places. Basically the less exterior air/noise that enters the noisier your cabin will be. Don't go blocking up air vents though, a cabin that moves air in a controlled maner is a nice, healthy place to be, you also need fresh air to replace the cabonised air content that inevitably builds when you have people in a car.

Also think about the materials you will use for triming. More fabric like material, more noise will get absorbed (to a degree). Generally speaking a soft foam covered in cloth acts as a good buffer & can traps some noise... think about your seats?

Next I would cover the exterior side of the wheel wells (mud guards?) of at least the front wheels, with both a deaner product (stick on, brush on or spray on) and exterior carpet. Yes, carpet, many luxury cars again have that in place already. This reduces both tyre noise and reduces the likely hood of wind turbulance creating more noise into the cabin.

Lastly, think about contacting surfaces. That is any two surfaces that touch, ie dash to wall, door metal to door card, etc, have a potential to rattle at different rates, when they rattle against each other, they buzz. At the contact point its good to have a material to break up the contact. A lot like how a rubber seal works between a door and the body of the car, the rubber in between acts like a dampener and isolator, reducing the likely hood of a rattle. You can use foams, rubber, fabrics, even stick on deaner. Many folks choose cover the entire door as such. I would take advantage of this and do similar since you only have two doors to treat.

Here is one (of many) sources for products you can buy help with the above.

http://www.secondskinaudio.com/index.php

There is additional extremes you can take, like making & welding in additional braces on places like doors, quaters, etc. Also buying hi silica content tyres, apparently they have reduced road noise. Also lining the engine bay with both deaner (weight) and foam (noise traps) products to minimise engine mechanical noise... but that would go against dub culture no??

I hope all that makes sence and that I haven't been too patronising either.
I do the above on all of my builds and really do notice a difference.

VWGuy · 04-20-2012

Wow that was quite a read.

I guess what I want and what I'll get are different. My intention is to keep the truck stock looking. There is no interior carpeting in the truck, just a couple of rubber mats. Since the floors are designed to be visible and painted as well as bulkheads, I won't be putting anything on them at all. Also, every window opens up including the windshields so there will be plenty of air. Prior to restoring this, I drove it as it was and it rattled like crazy.

I will line the roof, front, doors, sides and rear tank access area. The door panels are pressed board so there won't be much absorption there.

I already have sume Second Skin and look forward to installing it.

looking forward to see how this one turns out. parhaps will give me ideas for a project car. Awesome job sir

Man that vw is beautiful,nice stuff going in,it is going to be a very "live" interior as far as acoustics,but I could handle driving that down by ft Myers beach in the summer,there is a long stretch of road from the beach to Bonita springs runs next to he gulf,I ve spent many days off in the past listening to music on that drive.beaautiful job!cant wait to see it done.
