So you are willingly sacrificing engine cooling capability (there is no way an electric will keep up with a fully-engaged mechanical at 3500rpm!) to get a "better" AC system? Why don't you just add an additional electric fan to the the mechanical one, maybe in between radiators?
You see this is where unfounded comments fall down in a sensible debate, your statement in effect is saying put an electric fan that is apparentley not as powerfull in front of a mechanical fan! Surely the electric fans efforts are going to be lost to the power of the mechaincal fan right and may even cause an obstruction?
Remember because of the cowl all air has to come through both rads bar a little 'spill' coming in between the AC rad and the engine rad, the extra an electric fan will give you if mounted in front of the AC rad is only when stationary and the mechanical fan is not picking up any heat from the engine rad.
I don't need to jump out a building to know that it's going to hurt when I land. Go ahead and let us know how it goes.
See here you go again......it depends on how high the buiilding is!
Try to be a bit flexible in your thinking, I have already stated the savings are factual it is the amount that is debated.
I encountered similar comments when I enquired about dumping the 24 volt starter and fitting a 12 volt version and yet NONE of those people had tried it, plenty of 'I think this' or 'my friend said that' etc. Check out: https://forum.ih8mud.com/80-series-tech/365673-my-lc-80-thread.html The starter conversion must now be 18 months old, car works perfect and I have no starting issues, no worries about where to put another battery etc all the benefits of a standard 12v system. I stepped up to the plate AND DID IT!
You normally require maximum cooling at maximum power output. 3500rpm.
I sometimes tow 2000kgs over 1.5km high mountain passes in up to 45degC temps. Other times we're slogging it in deep sand at 30kmph for 100's of kms in even higher temps. You clearly need a decent setup to get enough cooling. I guess there is an argument that the mech fan is overkill (my temps drop very quickly as I hear the fan engage, and it does roar), but that's why I've bought a Landcruiser. It is overdesigned. This is a good thing.
But I stand by my statement that I think you should add an electric fan to the mech setup.
I completely agree that Toyota (and many other brands) do not know what you plan to do with your car so have to make sure that various components are 'up to snuff'. I have already stated I never tow, so already I am below what the cooling system 'might' have had to endure, I have fitted electric cooling fans on the following vehicles:
Sierra 2.3 Ghia, Ford Escort V8, V12 6.0 litre Jaguar Coupe 500 BHP and the Discovery in my avatar used in various competitions etc, and never had an issue.
I am pretty certain it will work and I was hoping that someone had genuine experience to save a little research on the best fans to use, for example 'X' fans are good in water etc. 4000+ cfm electric fans are available nowadays, do you have any idea how much the stock mechanical fans can pull? Lets suggest 6000 cfm but do you need that much?
You stated 'my temps drop very quickly when the fan engages' I do not intend to let my temps get that high in the first place, I will not be waiting for the the VC to come to the table, having such precise control that modern variable thermostats bring I will be moving air through the rad much earlier.
I am not a lover of electronics in off road vehicles but something as simple as a couple of fans should not be too much trouble, it appears I will drop the coin and at least try it and can state with authority whether it works or not.
Many thanks for your comments,
regards
Dave
