Where are the shots of the bullbar? I need to see what you have done with the oil coolers.
Before and after 'dyno' drive in/outs would be perfect for here! You'll have to trust my honesty:-) In regards the reverse snorkel pipe choice, reasons being for me was that this truck is mainly off highway at lower speeds. Past my 4.2TD's and current Mrs MB's GU's experienced dust/mist/mud blockages on TJM-Airtecs with tiny back drains, Safari snorkels were shitloads better. Second reason for the 6.5 beast is snow/sleet over winter in the HC. That ice builds up and blocks forward facing heads/drains in my opinion. Thirdly, as much as I shouldn't say this but I do know how to use a 'Hi-Lift' jack on my ute tray corners safely so a 'Ram-Head' would block my rack mount up top :-)
Haven't even had a chance to see this in person but looks very sexy mate!!!Quote:

Brunswick has sent me over a fix radiator fan flange to see if the viscous coupler is faulty. Immediate results astounding with at threats a 15 degree temp drop in all ranges.
Now struggling to keep the just around town temps over 78 degrees.
Spam have a dual electric fan set up that almost fits perfectly into the space behind the radiator and engine. Only 105mm in depth, with a static air flow of around 3,000 cfm.
I'm not a fan ( pardon the pun) of fixed fans. I can already see my fuel gauge drop before my eyes. Has any one ever played with a total electric solution or has advise based on experience with electric fans.
My thought is as follows:
1: no load on the engine hence no hit on fuel usage
2: can be controlled via a temp switch if need be and easily tinkered with.
3: if doing a creek crossing, can actually be turned off
4: at 1 in h20 static pressure, it sucks 45 amps of current ... ouch.
Any advise would be appreciated.
Kindest regards

5: Thermo fans still run after ignition is switched off, cooling the radiator downQuote:

Yeah, No brainer there, I have an aluminum Fabricator that has done some work for me that can build one. The shroud, perse, probably only needs to be the interface between the fans and the radiator as the Spal unit I'm looking at has a complete twin fan assembly in a frame already.Quote:

G'day Rainsey, I'm running 2 x Davies Craig 16" fans side by side that pull 2120 cfm each. My reasons were mainly for as you've suggested for easy shut off in creek crossings and heaps of pull still at lower rpm crawling speeds. I do believe though that a good mechanical fan system will outperform my setup on the highway. I do also need to add a second alternator though because each fan draws 19amps and are controlled through a 'Derale' twin thermo switch system roughly 10F degrees apart. So if I need to winch and both fans are on I'm stuffed at the moment. Other cooling mods underway should see the second fan almost not needed I'm hoping.
Gotta head to dinner now so can send some pics tomorrow if you need mate, Cheers!
Almost forgot, there is a USA mob doing a twin electric setup for the Duramax donk now and it's a massive 6,000cfm (3,000 x 2 I assume) The amp draw was frightening though, I'll try and find the link tomorrow for you too.
On the thurmo fan running after the engine is turned off, I would consider this superfluous as in my naive understanding we want to cool the block. With the engine off, no water is circulated hence we are probably waisting good battery capacity for no reason.Quote:

You have just hit on something that I never thought of, thank you .... winching. Having said that, most of my winching has been short periods, probably no more than half an hour and not in a situation where I could not stop. This does not mean this will change.Quote:

Don't want to winch off my stearing pump.
Thanks for the jog of the synaps. Good point.

Not sure Rainsey, I'm for from mechanically minded, but do believe new cars that have thermo's work the same way. See you point, with not cooling the block when switched off. I guess at least if it starts 2 get hot, you can switch it off and have the fans running cooling the radiator before is pops the cap and looses coolant :)Quote:

My guess is because the fans are set to constant power and the temp is still over what the factory temp is set at the temp switch when turned off, if that makes sense.Quote:

I have fitted my aux pump with a lot of effort, and have just this week received the gear pump from the UK and am looking at the PTO driven option - hassle is the BD exhaust and this places a lot of restrictions, plus the offset of the PTO output shaft and the mounting of the pump to PTO are going to be a big challenge. I will share what I eventually come up with.Quote:

I seriously will be interested in what you do. Sorry for sounding like a lazy F&*k but you know when you sit back and just realize how much you have started and how much you have actually finished ...
What I was after for the winch issue was a simple turnkey hydraulic pump solution that a vendor would say ... Here .. thi si what you need. Instead, I have been trying to contact over seas companies re hydraulic pup specs with absolutely no reply.
If I had a land rover or a derivative there of, no brainer....
Sorry for the negative response.

All good, and understand that life is simply about priorities and choices. I struggled just to get the flowrate of the nissan pump, then to find an aux. that would deliver in excess of that in a small package. The belt driven pump is supplied without a pulley, so you could fit a serpentine belt unit if required. mY PUMP IS RATED AT 25LPM@2000RPM PUMP SPEED . You are correct regards selection of the hydraulic style for extended winching, and if you search long enough will find a solution that meets your needs with minimal hassle - but as you say, you are time poor and we have all been there.Quote:

In regards shrouds for electric fans it is my belief that they are already built into them and with a twin setup I'd say my custom fat brass radiator appears at least 80% covered. Space wise with a GU 6.5 conversion I reckon a shroud would be near flat blocking sheet metal anyway. http://www.nissanpatrol.com.au/forum...017/03/122.jpg One very important lesson I've learnt the hard way on previous rigs is to never use those electric fan push through radiator zips or bolts with fender washers sometimes also supplied. They will destroy a radiators cores in off-road conditions IMO. Weld up proper mounting rails to bolt to and keep the fans just a few mm off touching the radiator. Pic below also of the 'Derale' control unit for the fans. http://www.nissanpatrol.com.au/forum...017/03/123.jpgIt has some great positives but also some quirks that I'm trying to adjust/iron out. Positive 1&2 are that it only requires 1 x sender and also auto kicks the second fan on 10F higher for emergencies. Issues are that it requires 10F below fan 1 kick off to turn off fan 2. I have combated this by a 60 sec full shutdown reset of its brain whilst coasting along. Once all cooling mods are done it should be ok but I'm thinking 2 x seperate senders with seperate adjustments each would be better. Cheers!

Anytime Rainsey mate, I'll PM mobile number. Just a thought, AB's donk party forum meetup is only a month away down here in Mexico. Phil is coming along with his beast and pizza ovens. I reckon a third 6.5er in attendance would be tops mate if you're free and up for a state border crossing into some good test country over the 4 day ANZAC weekend !
Come on Rainsey, its going to be tremendous weekend by all accounts. I am looking forward to putting some faces to the 'signatures' on the site.Quote:

Its ok, these thoughts will pass in time and all will be well. I have cleared a space under the bench in case you are able to harden up in time.Quote:

If your gvm is over nameplate then you run the risk of not being insured, and if you are unlucky and end up being put over a weigh bridge by the RTA, they will fine you and put you off the road.
I am in knoxfield, so pm me your contact details and we can meet. Mine is the 6.5 optimiser n/a manual conversion.

Hey mate, have a look on the forum for the thread about the big meetup on MB's property. I think it's called AB's donk party thread.Quote:

Good work Winnie! Yep the thread is: 'ABs Donk Party ANZAC Day Weekend' there was another shorter titled thread but the active one is above.
Guys, just back from a trip up to Butcher Country in Vic high country, thought I would share some stats.
Fuel econony 7.6km/L (22mpg)
Typical EGT cruising 240Deg C, ambient temps 28 Deg C, speed 100k/hr
Rad temp 64 DegC
Oil temps circa 68 Deg C
Max EGT under hard acceleration at 130km/hr long uphill pull, 550 DegC
Max temps off road low range. long climb, 88 Deg C rad, 92 Deg C oil, 400 Deg C EGT's
Mix of 400klm highway and 165 klm low range - 5km/hr sort of stuff.
Pretty happy with these numbers.
Good work Phil :-) Double Cheers Mate!!

Yep, spell check was the issue, lol
Finally squeezed my second battery back in again after Millweld's awesome 4" intake system stole some space :-)
http://www.nissanpatrol.com.au/forum...017/04/110.jpg Seriously running out of real estate now, no idea where the second alternator is going to go!

Phil mate, I also found this grease nipple hidden under where the old NA Donaldson filter was positioned.http://www.nissanpatrol.com.au/forum...017/04/111.jpgIt seems to be heading down into the bellhousing/adaptor plate. Did Brunswick mention to you what it is greasing, thrust bearing maybe?
Sent from my iPhone using Tapatalk
Nope, will have a look and see if mine has the same. You might have the surprise pack, that fails due to lack of lubrication!!! Hope not, but nothing in the paperwork and no manual supplied as such regards maintaining it. I would be surprised if its for a thrust bearing, can't see how they would config a grease point.
That is a beautiful looking setup compared to the BD green corrugated hose. Have a good look at my fitment on the get together. I have a huge amount of room under where my second alternator sits, so after I relocate the difflock compressor to the other side of the engine bay, I am going to install the endless air under the alternator. Your battery looks like it should 'go there', such a neat job.Quote:

Cheers Phil, I'm definitely stressing out now as I never knew it was there hidden away and I've done at least 50,000km in it now! There almost has to be some other need inside the conversion adaptor plate area as I too can't imagine grease near the clutch plate would be too good! Please do let me know if you find one too mate, Cheers!Quote:
