I have come across something interesting, don't know whether it is true, I saw that a racer is using clutch fluied in his radiator, apparently this makes the car run super cool, say if you used half water and half fluied....

Those that knows more than me....what do you think?

Clutch/brake fuild in the radiator, hmmm, na not for me thanks. Brake fuild makes rubber swell so would hate to see the inside of the hoses after 10 000km.

make a container to hold dry ice right at your intercooler Feel the rhythm... feel the ride...

Better to put halls or airwaves in your airbox!!!!

Gary...I am sure we could make up pipes that could handel this....

So it seems it is quite a big secret and very unknown.....a local racer uses this....his car runs relieble 10's all the time.....apperently the engine runs so cool it causes oil leaks because the operating temp stays to low.....he uses only clutch fluied....thats why I think if I use fluied and water 1/2-1/2....it will have all the benifets with no oil leaks.

I am sceptic myself....but thinking about it logically.....clutch and brake fluied is made to handel higher temps......

why wud it leak oil with low temp?


oil cold = thick
oil warm = thin


that soesnt add up 2 me seriosly

The oil heats up but the water ways runs cooler... making the engin run colder, because the engine runs cooler all gasgets do not expand with the heat needed and leaks may accur because the oil is thin and gasgets not heated up and expanded.....that is why it is not a good idea to drive a car hard when it was just started, because the gasgets has not set out the pressure may cause oil leaks and obviously in our cars the hot turbo meeting with cold oil spells desaster.

Put brake fuild in your hands and then run your hands under water... what happens?? It is an exothermic reaction.

If it is on a race car then it could be that he is draining the car after each race.

It is an exothermic reaction

Don't have a clue what that means....will google....I suppose the 2 don't react so good together....what will it react good with....anti-freeze?

exploring here......

Okay...searched.....an exothermic reaction happens when you mix water and accids....is brake fluid an accid?

The other info I searched says that brake fluid absorbs water.....but selicone based brake or clutch fluids does not.....that might be the answer.....

Clutch/brake fluid is hygroscopic, it absorbs water. Even a small amount of water in brake fluid reduces the boiling point by quite an amount, that is why its good to flush your brake fluid every 2 years at least.

A cooling system full of brake fluid would be very messy I'd imagine, any leak will destroy your paintwork.

I don't know what the specific heat capacity of brake fluid is but I'd be surprised if its any better than water.

Anyway running an engine too cool is bad for it. A cold engine has excessive running clearances, the ecu will overfuel coz it thinks its in the warmup cycle and anyway the hotter an engine can run the more thermally efficient it is. Thats why modern engines actually run hotter than older ones, they're designed that way.

Try clorine tablets, they always fun.

But seriously, a portable cryogenic de-ionising tank in the boot would work.

Um yeah if you wanna blow yourself up or burn your self something nasty.

They demonstrated this in our first year chemistry explosives lecture.
Dry chlorine powder and added a tiny amount brake fluid to it. The reaction was instantaneous and explosive to say the least. It was almost as violent as the thermite reaction, but much quicker to initiate.

Lets just say I went home after that and made sure there was no chlorine anywhere in the garage.

The boiling point of dot 4 is about 270 deg F....

If selicone bases fluid mixes with water will it still react the same when it gets on your paint.

Lets say a mix of 20/80

Ah Thermite, I what a cool toy, I miss playing and exploding stuff .
