I am looking at removing the engine fan and replacing it with twin thermo fans. I have a V8 and I have heard that the AU twin thermo fans are the ones to use on a torana. Does anyone have these on there torana and are they, just as good or better, than the engine fan or is there a better thermo fan on the market.
Thanks

i just fitted some (au thermos) to my lx 5ltr , you have to turn it upside down and trim 2 inches or so off the top(now bottom) and trim the edges to fit between the chassis rails , or you can bend the lips down to fit them in , they are a tight fit and take some time and patience to get right, but it looks great . i haven't got the motor going yet but it looks sh*t hot and id be surprised if they didn't work better than most.

Here are a few photos of mine on my project car, definitely turn them upside down so the wiring is on the underside, as mentioned they need a fair bit of trimming up to fit. everyone i have spoken to recons they will keep anything cool. Also they need twin 40A relays and 40A fuses. I also run mine through a davies craig fan controller.

Assuming I have the right part number it looks like the Flex-a-lite 410 will cost you around USD $500 delivered from Summit.
The Flex-a-lite 410 is rated at 2500 cfm.
A single 16" fan is rated between 2350 cfm and 3000 cfm depending on the manufacturer and model.
The AU fans are rated at around 3800 cfm and cost around $250 for a new OEM Bosch motor unit. The aftermarket copies are cheaper but the motors are not Bosch.

yep lx2 is right there the 410 didnt realise they were that dear! i only paid $300 a few years back as a mate brought them for his firebird and they didnt fit so i brought him the single version and we swapped
the au,s are probably the cheapest way to go but there not a straight bolt up but they work amazingly but look ugly as all hell when butchered to fit imo. had them on my 355 vnss and stayed cool even during 45 degree peak hr traffic

Thanks Andy i knew i had stuffed that image up , i'll figure it out one day!!
. Jass_hatch , you could go to your local wrecking yard and ask if they would give you a broken one that you could take away and 'trial fit' then once you know what you need to do you can do it to the new one. As far as being 'ugly as hell' i dont think they look that bad (not as nice as sshatch355's) .They look a little funny from underneath where it has been trimmed and the sides all but touch my unaltered chassis rails.

Rob mate you had it 99% of the way there. All you needed to do was put some kind of space before the whole lot. You just put it straight after the full stop and that's no good; the coding isn't designed to work like that.

Also have a look at the mondeos which are a far better fit than the AU's as they are a smaller twin fan assembly.They cost a bit more than the au's and are thinner if i remember but the cowling is kinda ugly.

+1 for the Mondeos if you don't mind the cowling.
I have them on my VH commodore (BOOOO!!!!) but they fitted well with a lot less cutting compared to the AU's.
Picked them up for $60-$80, a few relays and a thermometric switch and they do the job fine.
But as 1uzbt1 said they are abit ugly but the commodore is no show car.

In my opinion there is not much difference in appearance between the Mondeo and AU fans.

its more the fact that they are full of holes which the factory wiring harness snakes around.The fans are smaller aswell.
you can see in the second pic down in ls2lxhatch's post which is also a commy rad the size difference.
heres a set i fitted to a vk commy.
