Speaking to my mechanic tonight and mentioned your talc idea. He liked it so is going to give it a go tomorrow :)
Stay tuned.

Rainsey,
I have a Milemarker 12000lb hydraulic winch thats re-rated to 15000lb by an increase in pump pressure, designed by Milemarker in the USA. i imported the winch and pump at the same time, probably 10 yrs ago - my build thread is on outerlimits4x4.com, under PBBIZ2.
The pump I selected was belt driven. I was not happy with the clutch style of drive as it only had to die and the game was over, so I went for a direct driven pulley and slipped the 'A' section pulley on and off as required.
The pump was typically run at circa 1500engine rpm and had a 50% speed increase via the pulley. I had a pulley machined to mount onto the crank puleey cia the 4 bolts. This worked very well and gve me reasonable recovery speed, however I was never in the need for speed - not comp focused. The winch on one occasion ran continuously for 11 hrs - yes, had to winch a full 1.5klm as the track was like oil and no friction at all have trwin lockers, marks 85% reduction case and muddies at 12psi - no friction.
Anyway, specifically to your question, i have now decided to go with a PTO gearbox drive off the gearbox and direct drive the pump. I don't know what recovery speeds I will achieve with this setup, but if its too slow I will simply change the pump. Te system requires a small reservoir - mine is about a liter and I have installed an oil cooler as well to keep the oil temps down. I have winched in 40degC and the oil never got above 55DegC using an IR thermometer. The specs on the pump and flowrates are on the build - sorry its such a long time ago regards the details and my brain just can't hold that stuff indefinitely!.
I have already fitted a warn 15000lb electric winch to the rear as a safeguard. I was thinking about going hydraulic again but figured I was unlikely going to have to do the sort of redicous pull that I did that crazy day heading backwards, plus it gave me some versatility. I used the rear electric to great effect recently in a recovery whilst snow driving, so it was worth the pain to fit.
Hope this helps. I am not allergic to the belt drive, just wanted a constantly coupled pump without the electrical interlink of the clutch.
Well guys, my beast arrived back home last night. Wasn't with a bit of trauma from the transport mob, however some choice words and reminder of who is paying the bill resulted in the car arriving at 8pm. Here's where the excitement began because the car was sitting on the trailer with the driving lights on - nothin else. Guys drove it off and was moaning about being blinded all the way from Altona to Knox because the lights couldn't be turned off! Anyway, it was still light so i disconnected them and took it out for a quick squirt. Quick is probably not the best word, as you all know 1st is so short and the motor is tight and doesn't want to rev beyond 2500. But, it pulls like a train once it gets into 3rd and is 'peppy and toey' to say the least. The exhaust note is obvious but not intrusive when cruising - soon as you put the foot down you know its not a 2.8 under the bonnet!.
Spent the day sorting out the dual battery mounting and tidying up the wiring. Unsure how the PTO driven hydraulic pump is going to work as BD have mounted it upside down in order to clear the clutch slave cylinder. Nothin is leaking but the linkages are now on the bottom of the box, not the top, so will have to wait and see. Have to mount the difflock compressor and then the CTEK Dual battery system
One thing I noticed is the hand throttle is removed - is this normal on your vehicles? I would have preferred the option to activate a fast idle - maybe its not possible or simply easier to remove it - I have asked BD about it and will see what they come back with.
The build quality is really good, lots of small things sorted out. The wiring was my headache that i generated, so nothing to do with the conversion. Exhaust looks fine but is very tightly run in places - unsure if I am getting any knocking as still getting used to the rumble. The snorkle make a hell of a sucking noise compared to the 2.8 which at best you get a faint whstle from the turbo. Since its all velocity based, I think a 4" is on the cards sooner rather than later.
Went all the way from Melb to Perth etc return without a scratch on it. I do have 2 broken headlight covers and both the front fender parkers are out, so will check that later in the week.
Question
I have temperature monitoring gauges and can monitor up to 4 locations - where and what would you recommend. Temp threshold max is 300 degC. I was thinking inlet and outlet on engine for cooling, but what else? They are simple clamp on sensors with a crimp connector and hole to go over a bolt or stud.
So happy as a pig in mud right now.
Rainsey, further to my previous note about the hydraulic pump location, my plans to run off the PTO have hit a snag due to the PTO being upside down and the ultra tight location. I have decided to revert to the belt driven assy and have made a plate bracket that mounts on the drivers side of the motor with the pump sitting over the top of the lower radiator hose. I will post up some shots when its assembled. There is a bit of jinking around to sort out the hoses and expense also - circa $400 just for them, so have to get it right. Once I get this operational I will investigate and resolve the PTO option, probably with a different pump that can give me the flow at lower revs to the one I have.
Couple of shots. The angle for the installed plate is terrible, plus there is too much reflected light from under the car so the flash won't fire. I will have a crack later tonight in total darkness for the installed plate. I am yet to actually fit the pump as i have a small relocation of the starter motor cable to make so a hole is there, but it will work. The hose itself will simply be a 'whatever is avail, but looks in the order of 450mm inside dia' at a guess. The pump pulley is 50mm, the driver is 125mm, so nice step up at idle, plus when I get my hand throttle assy back from BD I can bounce the base revs up also. I intend tig welding an identical 125mm pulley onto the existing PS pulley - waiting for this to arrive from BD now. The outer pulley will have the centre removed.b Its a simple system that I used on my 2.8 for 10 yrs and its simple. Probably takes about 3 mins to adjust once you get the belt ready.Attachment 69802Attachment 69803Attachment 69804
I don't know if your engine is the same format - mine is Optimiser N/A, but the two bolts I am using are the ones that hold on the power steering bracket, 10mm or there abouts. I might end up installing slightly longer bolts as the bracket plate is 6mm and with the nut, there is only room for locktight - might get a nyloc on with uck, but no spring washer.
You can see the bracket is a total oddball. If you think its of value I can trace it out for you and post - I don't think a dimensioned drawing is going to be feasible as its 'cut to fit' and all using 'backyard garage tools', so would be nicer with a mill or laser cut. PM me with an address and i can do this over the weekend.
Thanks kindly for the photos. I have the turbo Optimiser and being that I am a thousand or so Km away from the truck at the moment and will be for the rest of the week, I cant compare your description to what I have.
Will be home in a week so will check then.
Kindest regards
Rainsey

OK, here is the clearer shot of the bracket installed. I am guessing this arrgt would be similar to yours? Anyway, when you get home you can advise. I will do a tracing of the bracket anyway as i am trying to get this thing together and once its bolted in I don't want to touch it!Attachment 69808
