Perhaps I best offer an explanation to the above.
There are 4 things I have done we mention in abbreviations, these are.
1. The connection between snorkel and the box with air filter in it (Airbox). Any of the 4wd shops will happily show you a photo of a car driving through deep water, take lots of your money and fit a snorkel for you. Trouble is, the way it connects to the to the air box is not always water prof which means in a deep crossing you will draw water into the airbox, it is just a matter of how much as small amounts can be tolerated. The small amounts will soak into the filter material and eventually with more driving engine heat will cause it to evaporate.
I have made my connection water proof all the way to the air box as I hope to play in deep crossings.
2. A result of the above modification is the connection from snorkel to air box is a larger size and with less restrictions which helps the turbo come to life earlier in the rev range under a given load, which = better low speed performance. In some cars there is a knock on effect for this of noise from the air intake system being heard from the snorkel, but for my 100 series it made no difference, the 105 it was a loud sound of the air being drawn in. A louder volume setting on the stereo fixed that.
3. I have swapped out the aftercooler for a bigger unit, the after cooler (Not intercooler as the advertising people prefer to call it) is for cooling the air the turbo heats up from the compression of the air and the heat transfer from the exhaust which drives the turbo. The cooler the air is when entering the engine the more dense it is and the more performance gained. Also the engine combustion temps are lower due to it. The unit I have fitted is possibly the biggest which would fit the space, it will reduce the compressed air temps a lot more then the original unit.
BUT, there is a knock on effect with the install of it and that some of the forced air flow to the A/C condenser and engine radiator is reduced, in the case of my 100 series, this effect is minimal.
4. I fitted a small air volume tank for my 12 volt compressor to charge up, the idea being as I'm driving of the beach I turn it on and the compressor charges up the tank to around 10 bar, so a 4 litre tank at 10 bar is = to 40 litre volume of gas. Road pressure for tyres is 40 psi (2.7 bar) so that pressure converted to volume means that I have about 28 litre volume of usable compressed air in the tank ready to go as a surge to fill the tyre more quickly, the compressor still runs charging the volume tank when I walk from 1 tyre to the other.
Now back to the van... sorry.
I mentioned before about the shower door not meeting the door stop when closed, and water passing as a result.
The forward wall which the door closes against bowed, I am not sure why, but in the heat of western QLD is when it became more apparent.
The solution was to space this wall out.
I don't have a pic before, but here is the after. The fixed part to the left of the door had a large gap at the top of about 10mm. Now the door over laps again as it should be.
How I did this was to add a small bit of 6mm ply in between the over head cupboard and showers front wall. This is the gap shown in the next pic, I also added some bathroom clear sealant to the gap to stop moisture, dust etc getting into the space.
I am slowly finding my way around this forum and reading about other vans and adventures.
In doing so, i stumbled upon my van...
This is helpful, as I'm trying to put forward the idea of going to fraser next year, if you read the previous owners post below, she did it on her own. Got to be happy about that.
I was on a blokes fishing trip there last year, and the previous trip was 21 years before, I must say that it was a lot nicer now then the last time.
I have been trying to convince the better half that with the right tides, we can go there with the van.
Now she's impressed, but first, got a trip across the big island to do...
Whilst I have been in the hospital for a 50 yr repair and service this week, the new tug was getting its 300,000 look over.
Injectors, new fuel lines, new harmonic, timing belt etc, valve re-set, inlet clean up. Also added a turbo boost control, a mate recons next thing I'll be on Tokyo Drift.
Lucky it is under the bonnet.
I was off to the wreckers and grabbed a airbox assy' out of a Deawoo Crapbox for $30 complete, then to Outback Marine for a bilge Blower, hose, skin fittings.
When i can use my hand again, I'm up for another 3" hole in the side of the van...
Fridge Cavity dust filtering done.
The fridge has a pair of vent fans at the top that blow out when fridge cycles.
The last trip had us parked in a dust bowl in Winton for 3 days, and that allowed a lot of dust in the fridge space.
I took the vent cover to Bursons and we played a game of which filters can be made to fit.
It was decided that due to the pair of 120 mm fans being low power that a lighter duty filter is required when compared to an engine inlet filter. I grabbed a pair of A/C Cabin filters.
Brand - Westfil
Pt Number - WACF0040
They fitted perfectly.
A piece of 9 mm marine ply was cut to shape and sicaflexed and stapled to the inside of the removable cover. To this the 2 x filters are held in place by 2 x strips of 25mm alloy.
I had to cut the lower section out of the fixed part of the fridge vent so the filteres passed by.
These filters tollerate water, so it makes them perfect for this job.
Now the pics.
The drive a few weeks ago of about 6 hours worth through torrential rain, I had what I call far too much rain water flow into the van from around the top thanks to the top roof hatch not sealing.
I have acquired a great idea from an offroad van makers and fitted a deflector to the front.
It is a strip of alloy with a 30 mm and 60 mm face and 110 degree bend.It is mounted with some small screws and the good sica. The black strip is additional sealing rubber to fill the gaps due to uneven manufacturing of the van between the van and roof seal.
I should add, at the time of this rain, all of the sensible folk were off the road, me..... , I've never been accused of being sensible I made the most of the quiet driving conditions. As I expect this may happen again, I decided the $50 I spent on this was worth it.
Finished the positive pressure vent system off. A vent port outside behind the right side tunnel boot hatch allows fresh air to be drawn in.
Yes, I would like to have had it up higher but was too hard, however, I drank a beer in Winton with a bloke who's exact system I have copied in his Jayco, and he swears by his set up.
The Outside air is drawn through the car airfilter and then into the fan, the outlet is inn below the front seat.
The set up looks to be close the the gas heater, and some of it is, I am happy with the gap between the 2 as far as heat is concerned.
It is wired in for permanent power and can be switched on or off without walking inside the van. I did think about sing a spare in the 12 pin plug to control it inside the car, but can't be bothered, beside, I like to get out and look around at the start and end of gravel roads.
I scored some corflute material for a bargain.
Made some heat insulation panels for the rear windows and a heat and light shield for the 2 x screens on the dash. The window panels are painted black on the outside. They also are to protect the window tint.
I have added a Engine Coolant Temp Gauge, sensing the top hose, and a Pyro. With the 1hz I have always had a need to keep an eye on these, but this car I don't as much, but is a nice security measure.
The Tug has 3 x traiddie rails for a roof rack, I like these as they are versatile, I wanted a basket but also to carry a Kayak as well. My budget of $120 would be easily blown with something made to suit.
Cheap and Narsty Auto have a special going for about $115 on small baskets, so I grabbed 1.
Then sliced a 300mm section out of the middle and welded the 2 sections together.
Next, I cut across to add 300mm to the length.
Now I have a basket which allows the Kayak to fir long side, and space in the middle for the paddle.
G'day from Wave Rock.
The jobs i did in getting ready for this trip are almost 100%, just 1 screw up.
Air foil across in front of the roof and extra hatch seals are 100%. I drove through sheets of rain near broken hill and eastern end of eyre hwy, van is dry inside, sweet,$60 well spent.
I did about 260 k's from Norseman to Hyden today in the dust.
Fridge vent filters 100%, not blocked and nill flow issue at all.
Froced draft vent is a 200% suscess, it kept the van free of dust and works to keep it cool when on the road.
My 5 tubes of sealant in under is a bit of a failure, i missed the step base, there is a lot of dust around that part from the chassis side of the plastic insert, pics later.
Sadly I am few days ahead of scedual due to poor weather, the wonderful rain inland aus has been getting has stopped me from my deviations i wanted.
I'd be shot if I complained ahout how green it is all the way across NSW to SA boarder now, so I wont.
I should add, I also made a cover for the inside of the door to block the vent. It is made with some bargin priced corflute and held on by velco so i can take it of when not driving.
Looking at it now, i should have added extra bit of velco above so i can mount the panel above the vent for ease of stowage.
Finished a 1,200 k run about the sth west corner, very happy with the tug and van, 18 L/100 is good considering all the hills, start stops and deviations. Even went into some fun off road situations, its nice having all boots on the deck in trying conditions.
Planning the trip home is underway.
Hasn't all gone my way, apparently the Christmas and New Year period is popular for holidays, this is effecting our travels.
Considering that and most places want a minimum of 3 or 5 nights bookings, we've got several places allowing us to stay for a 1 or 2 night stay on the way. Many places have allocated us the last spots etc.
Just waiting for an old work mate to get back to me to set the course into Vic.
So far it is all is well, hope to keep it this way.
Although the front mattress set up is going, I may eve try to sort it out here in perth. The narrow thick section (my part) has turned into a Canoe with a sharp edge for a zipper. The other section is fine.
