Somebody just buy one. Stop dithering...
Nick also has one, some of you know him in person when he previously lived in the UK. This is his car here, with him driving it.

Very compelling video footage there 
(Hopefully stating this doesn't open up an internet can of worms and we discuss this for 5 pages) Nicks cars AC system is actually a little different in that it is on a 30sec timer for some reason.
I have an early 2014 model VF GTS, another customer has an early 2014 model and both AC systems turn on as soon as you turn the AC on, in Nicks car you turn the AC on and then 30sec later it turns on, Nicks is a late 2014 MY15 model...We have also had other late 2014 and 2015 models and they turn on straight away, the 2008-2012 VE's and the older VT-VZ Monaro's/commodores all turn on straight away too....Nick just got some weird timer function on his one...LOL
We can tell this as we monitor the AC system pressure, you may not be able to see in the video unless you zoom right in on the phone monitoring the pressure but basically when the system is off the pressure is very low and then when it turns on it jumps up by 50-100psi depending on the outside temp.
You can see the AC pressure here on the torque pro app at the very top of the screen:
As you can see in the video we are like "okay turning it on right now" and if you look at the timing mark on the video this is 0.43sec then we both start questioning if its on or not as the pressure didn't increase we both then start mucking around with fan speeds and recirculate etc as we both know it hasn't started up yet and then 36sec later we are both like "okay NOW it's actually on" and this is at 1:19sec which is 36sec after we first switched it on.
We have no idea why his car has this delay we have not seen any other car have such a delay like this before. The ECU shows a 6sec delay after going WOT but the ECU has near zero control over the AC, it's more so the BCM that is controlling it.
Weird one but thats the only thing with his car and it's going to be like that regardless of having a chiller or not.
(Hopefully stating this doesn't open up an internet can of worms and we discuss this for 5 pages)
Either way he runs his chiller 100% of the time, so he doesn't ever have a 30sec delay, the video was simply a speed test showing how fast we get to the min temp, also to note, since we filmed this video we have found that slower speeds actually cool it down colder and faster, speeds between 60-80km/h (37-49mph) are optimal, we can get much colder much faster, what happens is the air speed is fast enough for cooling the condenser but not too fast, the higher speed 100-110km/h (62-68mph) lowers the system pressure a touch more than the slower speed and this results in less cooling, logic would then think ok increase the pressure to match that slower speed....that actually doesn't work, we tried it, the increase in pressure at the higher speed results in a hotter r134a temperature and cooling isn't as good.
We have also found when drag racing in 30c ambient we can turn the car on 6-7minutes at idle before the race and reach our min temp, so basically we just turn it on 10min before we start racing.
So there was plenty of R&D into what amount of gas gets the coldest the fastest, I probably put 15,000km (9320miles) on my car just testing different system pressures, it also worked out well as we were able to log my car and Nicks car side by side on the same roads when he had no chiller installed so we could see his AC pressure and mine, we also repeated this once we installed his, this was very funny we would be on the hands free phone talking and be like okay I just hit 7c then 1 sec later when he reached the same point of the road "me too" and this was basically a mirror image of what happened over a 30-60min drive any time my temp increases by 1 degree so did his, we then swapped him in front me behind and we had the exact same result he would call out the temp when i hit the same dip/bump/hill in the road my temp would be the same.

Good luck trying to get any other system this cold!
Well as you know we are crazy about getting cold temperatures, we have made another improvement to our interchiller system to make it even colder. These were the results today at Morpowa Auto & Dyno Centre in South Australia on a magnuson 2300 heartbeat. Thats right thats actually ice formation on the lines. We always use 50/50 anti freeze so this is perfectly safe for any of the nannies out there concerned about it.

Must be a "Nanny" but is that a good thing? How cold does it need to be, I cannot imagine the rest of the IC circuit is designed for that.
Still watching with interest though now a few people have had kits delivered to UK. Particularly interested to find out how easy it is to fit to a VZ CV8 Monaro.

Did GM not do winter testing of our cars in wind tunnels and different locations around the world at -40c or more?Still watching with interest though now a few people have had kits delivered to UK. Particularly interested to find out how easy it is to fit to a VZ CV8 Monaro.
Just remember you can get these cold temp in your car as it is now, you just need to be driving it in freezing cold conditions to do so.
What is being achieved temperature wise is easily done daily in certain parts of the world. The only issue then is the roads are also very icy and slippery.

GM maybe but I doubt Magnusson did 
Still mighty impressive though.
I know a couple of guys in Canada that run Heartbeats and have driven them in the freezing cold winter. Still mighty impressive though.Just keep in mind like i keep saying it's doing what could be done if you drove in the right conditions.
Ice formation like this only happens when it's humid enough for condensation to form and then turn into ice.
We all know what temps are required to get ice formation...bloody freezing cold.

Well done, but FFS use a decent camera and tripod next time - the shaky hand-held vid with tiny cars in the distance just doesn't look professional IMO.http://www.youtube.com/watch?v=-Lornbna_DI

first time at the track with the current setup never intended to make a movie out of it, car ran a good time, customer of ours filmed it put a little video together. next time i'll be sure to hire a film crew for the day
