OK, I am just about at my limit with the posting issues , cant attach images, unauthorised action, refresh the page, have to log back in, then post disappears.

So the setup is finished, was cable size to the pump that was the stalling issue. Runs at 11.4lpm.

Righto photos wont load, good night.

Here are the missing images.

OK, the additional W2A heat exchanger between the air filter and inlet to s/c is manufactured, fitted, then removed for painting, will fit tomorrow. Its tight, too tight, but now at least I have something that does fit, however it will almost be the trial unit as gong to see about a custom unit once this gets on the road and proven.. The units is a 5" dia x 10" long, reduced to 3" in/out. The follow up unit is going to have 4" to match the airbox and then neck down to 3.5" for the s/c inlet manifold.

Then its simply a task to plumb it up and both systems are complete.. Had to chop the length of the airbox by 50mm, but filter still remains the same size and is easy to install/remove.Inlet w2a.jpg

I really need to see this beast when it's finished Phil. You're a patient man.

Its getting very close to completion. This should be the final chapter, apart from some rationalisation in the rear pod as I am still using the rear seat, which is not to plan for storage. I carry too much shit, but its a habit I am trying to break.

30 days to make a habit, a lifetime to break it.
I too am looking forward to the completion of this beast.
It's been epic.

Righto, I can finally claim a win! I connected the under bonnet W2A today, into the Interchiller circuit, and where I once would have a climbing water temp at idle of ambient plus 10 degC, and saw water temps in this circuit regularly at 70 degC + on the recent NT trip, I achieved an at rest water temp of ZERO after 5 minutes of idle, and 6 Deg C after 1hr of idle.

My next job is to insulate the hoses as they condense water quite readily and the steel fittings are now freezing up with frost. The intercooler barel is 90% insulated, as is the air filter box from the engine radiant heat.hose condensation.jpghose route to pump.jpgInlet w2a.jpgnew revised water temp.jpgNT temps pre mods.jpgroof set up 1.jpgroof set up 2.jpgRoofrack 2.jpgW2A roofrack module.jpgbarrel w2a.jpg

Another 6 hrs on the truck today, insulated all the top side hoses and engine bay, and need to do the ones under the truck - used some standard 1" bore rubber sleeves from Clark rubber, a million cable ties, bugger of a job to do it thoroughly. Wired up the second intercooler pump to an ignition circuit so now everything comes on automatically except the fans on the roof HEX which will be on demand. Tomorrow I will flip the front driveshaft and the work out the process to drop the gearbox crossmember for the cutout installation - not arrived yet.

Wife home from Thailand Sunday arvo so all work ends Saturday, house tidy up Sunday AM, happy days.

Added this 1.5L header tank into the circuit on the roof, and picked up 1LPM flowrate with the extra head and better air purging I think. Flowrate on rooftop system is 12.5LPM by the flowmeter and 17lpm for the incoming air circuit unit under the bonnet.

Fitted a replacement set of coils in the rear today, the originals wier Dobimsons C45-325 coils, rated 400kg and 3" lift19mm wire, constant rating ,fitting with the Airbagman 3" airbags and kevlar sleeves. I had problems with the airlines on the trip, leaks etc, and found when employed the vehicle wobbled whilst driving down the road - was a bloody handful to be honest, so upgraded to Dobinsons C45-315 coils which are 250-400 variable rating , 4" lift and 22mm wire and running without airbags. I installed the coils today and whilst it sits 20mm higher than original I still have only 15mm under the extended bumpstps - I don't know - its just a perception, but a quick ride around the block and confirms the overall result is fine.

What I did find however is the ARB BP51 rear shockers have been making contact with the factory bump plates on the rear axle housing, essentially carving the side off the adjustment knobs - bloody mess.

Anyway, I cut the bump stop plate off by approx 20mm and the clearance is how it should be. I have made contact with ARB Kilsyth and started the warranty evaluation process, and also after speaking with @Rossco, seems its a requirement to cut back the bump stop mount, but not mentioned in the ARB docs - another beesting .

Ok, back from site, decided to install 30mm coil rubbers in place of the 5mm units on top of the coil to get the car sitting a smidge above level, front down. This is the fourth time dicking around with coils so the change over time is coming down. Anyway, pain free activity, added 25mm effective lift at the rear and the vehicle is sitting a smidge above level. I think with the wire diameter increase and this small correction I will get the stance I am looking for - essentially stock within the limits. Took it for a brief spin around the block to settle the coils and it rides quite nicely.

As an aside I have been helping out a young guy with a range of parts for the last 6 months or so, has a 1994 GQ LWB, fitted with a fully engineered Barra Turbo, he dropped around to pick up an interior cross body console and I also gifted him the 400kg coils and airbags, and in turn he took me for a squirt in the beats - HOLY MOTHER OF GOD, unbelievable acceleration without fuss, under bonnet is so tidy, puts my build in the shade, this thing flies, making 250KW at the rear wheels with a moderate tune, extraordinary. Holds 90- 100 on the radiator with thermos, has paid a lot of attention to details, really spectacular build in my view, admittedly a totally different approach to my build but his is power on tap, very impressive. Unsure it would match the grunt of mine under load, but he is getting a load of fun out of his and its a sleeper build, just the exhaust note give it away as not a 2.8TD, - still has the stickers on the rear quarter the bugger! Very impressive .
