"Coolant" is simply there to lower the freezing point and also as a corrosion inhibitor. Ethylene Glycol/Triethylene Glycol for example has a specific heat capacity of one half of water! That means it can carry half as much thermal energy given the same temperature rise as Water alone can.

Ethylene Glycol *does* increase the boiling point, but it's rarely needed since the pressurized cooling system does a nice job of raising the boiling point too!

The main point is that putting Anti-freeze in will not improve your cooling system, it's merely there to inhibit corrosion, harvesting of bacteria, and drop the freezing point.

Agree with the GTi6 should run at 83*C - but the hotspots being reduced by Anti-Freeze in the system isn't true - soon as you increase the pressure in the system, the boiling point increases also.

Not being a cock here, but...

You should never be to the point of nucleate boiling in an engine, if you're having to use Anti-Freeze to prevent Nucleate boiling, you've got far bigger issues. To overcome that, you'd need a good 50% increase in specific heat capacity of the entire cooling system (i.e. system capacity & flow) to remove the heat since at 50/50 Anti-Freeze mix, you've dropped your heat capacity of the coolant by 25%.

I'm sure you see my point, if you're struggling with the cooling system removing heat with no Anti-Freeze in, adding it will only make things worse since at 83*C you should never be hitting the boiling point at any area inside the engine - going from your average 83*C coolant to >105*C on the cylinder walls - not going to happen unless you've got real problems

It does lead me to concern on a few points, mainly the air temps do not seem to reduce even after almost a minute of no throttle. At some states he is seeing 40deg! hopefully he can get out again and get another log to see if there is any difference. I have suggested an inclosed filter to try make it draw from a less heated area.

That was when the coolant temps were much higher and he had to have the fans on when driving lol

Hopefully should be somewhat better now.

See if it goes bang up the hill :p or if he has another off like last year

Either way should make a good noise!

Have a look on YouTube, they found that while air is flowing through it there's virtually no difference but when stationary at idle the heat soak temps were less than halved in comparison.

I see your peugeot tech status has given you a fantastic grounding in solid engineering knowledge. Have a look in the couch for a thread on that, you might even learn something.

My intercooler is painted silver because I'm a tart but I'm tempted to buy a new one just to see how much truth is in what they are saying.
I also think I'm getting quite a bit of extra heat from the charger anyway as although it's still boosting fine, it's really not in a great condition so I need to do something about that. The Mini M45s are a completely different design body but the rotors are the same size and fitment as mine being the same displacement. Difference is though my charger is gen1 and the mini ones are gen3 so improved rotor design and better coatings so I'm hoping to get a mini charger and sort of build a hybrid if you like. I also think this could be one reason why Stef is seeing only 25 degrees temps. Either that or his air temp sensor isn't calibrated at all and his is just as bad as mine
