AU cooling issues

T'subaru · Post by **T'subaru** » Mon Jan 25, 2010 2:45 am

You folks made our news last night. Sydney was 109 degrees F. if Im not mistaken. We seldom hit 100 in the western part of our state. About the only time I could use a/c is when I'm stuck in some of our worst traffic on the freeway system here..probably the worst time to use subi ac.
Keep it cool,
Mark

Lol, and that wasn't a really hot day!!! When I was a commercial Pilot back in the day, ok only about 10 years ago, used to hoon around in the Cirrus SR22. I went to Alice Springs, and had the aircraft parked. I returned about 2 hours later to find the dash had melted and warped. Now cirrus has tested the components in the toughest conditions known to man, Arizona desert apparantly. But I reakon they should have tried the ozzy outback!! Anyway cirrus were amazed at the australian outback conditions and did replace the melted components under warrantly!

Heh... Worst weather I've been in is 52°C was in remote South Australia, it was like.. melting hot - you couldnt do anything!
February 8th last year was last hotest day, cant remember how hot, i think it was 46-48degrees. (that is when the bad wild fires in Victoria)
This weeks weather in Melbourne is alright, not even saying anything because its nothing... melbourne & Sydney/Brisbane have different weather pattern.. I like Hobart climate - thats me.

I lived out in Windorah in far western Queensland during the early eighties and it was so hot, that one day a big sand goanna walked past me carrying a water bag. boom boom.

But seriously, I have an EA82T in a brumby and it tends to run quite warm on our hot days, especially pulling up over some of our hilly country here in Toowoomba.

My thoughts at this stage is to get another core put in the radiator to bring it up to a three core unit and ditch the craig davey fan and get the original slimline subaru electric fan that sits on that Y frame on the passenger side of the radiator.....any thoughts. (Not much space between the engine and radiator I must admit)

Wow, had a friends dash melt beyond repair but it was assisted by his removable sunroof he tossed in the back seat.

I really like the Brumbyrunners set up

Yeah, you do know it is a HOT day when the big boy 'roos are just hanging - literally, and a goanna, 24" between the axles, just looks at you , you can see he is thinking "what's a human doing out in this heat?" The hot nights are hard to escape.

I am thinking I may have space to transversely mount an AC condenser with fan on my RHS chassis rail to feed between the thermostat and turbo, running coolant this time instead of R34

You know its hot when all the flies are doing is staying motionless in the shade! at the coolest place they can find!

You know its hot when you're a fridgy in a roof fixing someone's AC because they're whinging that the ceramic cow holding a thermometer in their office is saying it's 26 degrees and "that is unacceptable", It's over 50 in the roof, fix your own damn aircon.

Cheers,

Jake.

username only says it is over 50 C coz most digital thermometers top out at 50C. I reckon 50C in a roof space is comfortable, any more is not

Yeah, some roof spaces and plant rooms get way over 50, 60 even. The main problem is air flow though, You start dripping because there is no air moving over your body. Being on the roof in direct sunlight is bad too. Im going to age terribly because of my chosen profession.

Cheers,

Jake.

My hottest day was about 18 months ago.... Actually i think it may have been July 17 2008. I spent 2 hours on the roof of a house betweem 1:30pm and 3:30pm (flat top roof paved in white slate stone). It was in a place called Najaf about 200km south of Baghdad, Iraq. I was wearing full length thick cotton pants, a light coton T-shirt, Kevlar/steel plate body armour and thick long-sleve cotton shirt over the vest, Kevlar helmet, Tactical vest and back pack. After leaving that dreadfull roof there was not one part of my body that was not soaking wet. I went through 3 litres of water and a litre of Gatorade.

Upon returning back to base I noticed an american clock style thermometer on the side of a cabin in the shade, at 4:30 in the afternoon it read 132 deg farenheight = 55 deg celcius. I would have loved to have a thermometer on that roof an hour and a half before hand. It was like trying to work in an oven. My vest still has the salt stains on it lol.

Cheers

I like the fridgy name, overhere in the building trades we have tin knockers ( hvac guys) sparkies and tin benders. They usually call me the window guy. Hottest ive had to work in was 112f average for bout 3 weeks, reclad job and the bldg was fully wrapped in staging, took the suns heat all day.

Then there are those chippies (carpenters) that learn quickly underpants do have a sun protection factor when in old style footy shorts- preventing sunburn from reflection off new white concrete floors

You immediately have my respect. My brother was an M1A1 abrams pilot during desert storm.

Well, sized up the AC condensor along the chassis rail to find 'it' won't fit transversely as brake master gets in the way. If I rerouted coil and coil lead it may fit LHS, but maybe just a condensor out of a smaller application for RHS. My fear is that although runs cool on hot days, maybe not so up long mountain runs on stinkers, and thinking cheap and cheerful idea of using condensor and fan inline with turbo and elec fan....
