Posted: Thu Apr 19, 2018 8:43 am Post subject: Air Box Modification |
|
|
Modify the air box to reduce noise.
Simply put, you install sound deadening inside the air box and modify the air intake. All can be reversed if you hate it.
Supplies:
FatMat or equivalent
2.5"to 2" rubber plumbing reducer
RTV
Clamp
nylon ties
Cut the reducer down.
Insert into the air box:
How it'll look
Stick sound deadening into box, top and bottom, don't block the filter.
You can put RTV around adapter, then lightly clamp hose to it:
The hose goes up and under the driver's side, tie it down with the nylon zip ties. You can point the opening towards the front or the rear, you pick.
It's very subjective, but I find this much quieter. Note that I also covered the outside of the resonator with FatMat, and painted it black. (no photos)
Edit May 28: so, pointing the air input hose towards the tire was one of my dumber ideas, NFG. Got into a torrential rain storm and Zetec started to skip. Laid in the mud and yanked off the hose! Install the air hose end someplace where this won’t happen. I’m looking for another air box to try a more snorkel approach. _________________ ________________________________________

Posted: Thu Apr 19, 2018 8:52 am Post subject: Muffler hanger modification |
|
|
Dan Gravelle came up with this and I like it.
Parts:
new muffler hangers:
Here are the parts:
Summit Racing:
WLK-17904 , muffler
2-WLK-36273, clamps
Amazon:
https://www.amazon.com/gp/product/B000CQDL94/ref=od_aui_detailpages00?
FLAPS:
2-3/16x2" bolts with fiber lock nuts
2" muffler clamp (never liked the one that came with the kit, this one is solid)
The pictures show what Dan did, no explanations necessary. The Bostig recommended muffler clamp is $18 at FLAPs, so not buying that will help cover these costs.

Posted: Thu Apr 19, 2018 9:09 am Post subject: Vacuum Inlet |
|
|
The vacuum inlet saves you lots of trouble with the Ford OEM "Chinese-finger puzzle" vacuum fitting. This is a modification you should do during engine prep, not once you've installed it. This takes all of five minutes.
Drill with 1/2" bit
Pic or small screwdriver
RTV
Vacuum inlet
Here's the inlet:
Ford's troublesome hose connect on intake manifold:
So during engine prep, drill straight in with a 1/2 inch drill bit, go slow, and you'll know when the fitting is off:
Pick out the rest of the plastic and the metal washer thing:
A little RTV on it, and tap into place, then heat up a nail and melt the edges around it.

I threw the stock hanger system out after the first ride, too much vibration , I went with a regular hanger at the inlet and a hanger from the tailpipe to body using rubber donuts. Also added this cold air intake, it felt like it made more power.

Great thread! I like the air box mod as it seems like a source of noise under some conditions.
Muffler heat shield I made in an attempt to reduce temp of the a/c compressor. I haven’t measured temps but it seems like it would be helpful. (I’m intrigued by the Catifold or Manicat that I’ve seen in the fb page and will be interested to see an install.)
Aluminum sheet cut and bent to wrap around the muffler and hopefully deflect heat away from the a/c compressor. There’s still a bunch of heat coming off the cat and I don’t know how the air flows in the engine compartment.

Posted: Thu Apr 19, 2018 10:05 am Post subject: Move the power steering reservoir |
|
|
The power steering reservoir moved inside the area where the air box used to be, gives you a better angle on the AGFA hose. Much easier installation of the power steering pump, and all but disappears .
I did this with the taillight off. Two pieces of scrap aluminum, screwed into the opening, and the reservoir bracket then attached. Sorry the photos aren't very good, but you can finagle your own setup.
The white hose is the BlazeCut system, I've already burned down one unit, so I'm a bit paranoid. _________________ ________________________________________

|
|
Trim Firewall for better access before doing the install. I cut up and across to make a bigger opening on the passenger side. The photo is poor, but you can extrapolate where to cut it. Use a file to dull the edges afterwards, and protect your hands. Now you can remove/install the starter without going under the van.

Posted: Thu Apr 19, 2018 10:21 am Post subject: Heat shield |
|
|
Similar to Jimf909's very elegant heat shield, but more Mickey Mouse.
I took L brackets, maybe 3" on a side, and bent them into a U shape, with one side lower. Drilled a hole and attached them to the compressor, using the compressor's mounting bolts. Then bent an old cooking sheet into an L, and attached it. You could also use an old license plate.
Note this is an offset muffler, not the standard Bostig recommended one. Cost about $20

A couple mods that I posted in the Bostig tips & tricks section awhile ago.
The p/s reservoir move. Simply add a spacer to the stock Bostig holder.
Airbox mod.
Overflow bottle. Gives more room around the air box.
For Syncros, makes for more room around the coolant pipes.
Also for Syncros, sealing the bell housing for water crossings.
And the new bell housing vent location.
And the a/c hose routing around the rear of the engine.
I also moved the muffler over like others have and used the smaller one found by Lemoncove (I think )

Has anyone installed an alloy(?) valve cover? I’ve needed to replace my valve cover gasket about once a year. I’ve heard the alloy cover helps but I’m also open to other ideas.
Thanks. _________________ - Jim

Mstaboo, very nice and excellent photos!
Jimf909, what happens to the cam cover gasket that it fails? These are pretty solid. I use a dab of RTV on each corner when re-installing the cover, and torque it down carefully. _________________ ________________________________________

Awesome thread! So my bostig rattles stuff around at idle and over 60 is fairly loud but I think it's exhaust, not intake, that's producing the noise.
I've heard a lot of people say the intake is loud but I'm curious what situation (speed/rpm) they're referring to. I have an rg8 so maybe it's quieter or I'm just lucky, but it doesn't seem to be a problem for me - or I could be hearing it and not realizing it's the intake... _________________ TheVanTracker.com - Kill Switch + GPS Tracker + Door-open alerts, made specifically for the Vanagon!

Yes, Signalocity used one on his fantastic build. Page three I believe.

MsTaboo,
I noticed you're not using a fill tower, tell me more about your arrangement. How do you fill the system, via the radiator vent? I have an old style fill tower and bracket if you want it. (cheap)
P.S. engine bay much too clean! _________________ ________________________________________

My engine bay is a combination of Bostig kits. I have upgraded various parts of the system over the years. My original system was a Group 6 with the tubular engine cradle, first low profile oil pan, ECU within the engine bay, etc.
The coolant fill is from the 2010 kit and is integral to the thermostat housing at front of engine. (you can see it in front of the oil cap) That was an upgrade from the earlier setup!
Someday I'll probably buy the latest fill/tank combo, but that means also buying the aluminum thermostat housing ($$) as I don't want to go backwards to the stock plastic Focus housing.
I haven't change it out yet because it works fine. Thanks for the offer!
Original '09 install
First upgrade
Latest
One of the mods I would really like to see would be a new downward projecting exhaust header to help get heat away from the engine lid.
I've been contemplating going to an exhaust shop and having them fab something together- none of the aftermarket Focus/Zetec headers will work. _________________ Currently:

I was planning on building one last winter but got busy with other stuff.
Our installs are similar. Started as G14 and updated as things evolved.
What group interest is there in a proprietary header? What do people think a reasonable price would be. If there is adequate interest I could do a group build. |

Are you all aware of the new Bostig header/cat combination, using a 2002-2007 non-turbo Mitsubishi lancer manifold?
https://bostig.zendesk.com/hc/en-us/articles/360000349766-RG9-SK-E-and-rockauto-order-list
(you'll need to set up Bostig Zendesk credentials to view this article, but it's worth it)
Not totally ready for market, but this is where things are going with the header/cat system.
