hey guys, whats your thoughts on using coolant in the water air intercooler? atm its got straight water and appears to be boiling and overflowing.....

As long as it's a sealed loop it should be ok.

Should be fine, but I would ask the guys you got it from.

Once i get my Water 2 Air system set up i will be running coolant

get some redline water wetter

its christmas... they on holiday :(

redline water wetter... hmmmm whats it do?

the water wetter helsp dissipate heat better... and stop the boiling and frezing... i think

Its redlines version of coolant,

Anything 50/50 is fine, we are going to be using a Castrol Concentrate Coolant in Brads, mixed in 50:50 blend.

redline water wetter or motul mocool, just let me know if ya want some pete i'll get some friday from work, out of water wetter atm but have a couple of bottles of mocool left

how much $$ we talkin for this stuff?

Could always run water/meth at a 50/50 mix.

It also shouldnt be boiling over, either your water cooler is too small/not getting enough air etc. Or your heat exchanger is too small and you should be running more water.

*Personally* I would run a thermo fan set up on the water cooler, to draw air through it, triggered by a temp switch.

they say alcohol has better cooling properties then water due to its quicker oxidisation rate/disipation rate. I dont know how well this works when you are using the alcohol to transfer the heat away to the heatexhanger which then uses air to cool the heated alcohol? i dont know if any of the benefits would carry over.

a 50/50blend of metho and water will be a easily test and is also quite hard to ignite so dont have to worry about fires and what not.

That water wetter stuff supposedly thins the water out, making its heat absorbsion and transfer much better. Ive seen the results of it at work, dropping coolant temp some 8 degrees on no other changes to the same car. So it obviosuly does something.

I would be more concerned about how well the heatexchanger is set up then what type of fluid is in it. As this item will give you thee most benefit if its not working proerply and you fix it.

if you have a look in my build thread, you will see the front radiator.. the guys use this same set up for trackdays, etc.. I think maybe its more the water resevoir in the engine bay heating up as its on the strut tower and is very hot to touch....

I Think I'll wait to after xmas and see the guys, for now ill stick to filling it up I think just to be safe,

Which thread do you mean QMD? went through your thread in members machines and cant find the radiator pic?

The heat exchanger looks like a decent sized unit though.

How much water does your heat exchanger, lines, and radiator hold?

You cant really fit a much bigger heat exchanger, so without seeing the radiator, I'de say other options are: custom alloy radiator (for the w/a cooler set up), and trialing different mixes of water with metho/coolant etc.

What are your intake temps after the heat exchanger btw?

how much $$ we talkin for this stuff?


retail is bout $45 a bottle so less than that :)

just a thought how about straight coolant we run straight coolant in our buggy and it gets flogged for a fews hours at a time with no issues or overheating.

too much glycol for my liking, but i guess whatever floats ya boat,

And where is the problem in that.Please explain.i didn't think there was such a thing as to much we have been running this way for 5 yrs or so and never had an issue with overheating or corrosion.

Pure glycol is corrosive, hence why you need to mix it with water

we have been running this way for 5 yrs or so and never had an issue with overheating or corrosion.

guess we have been lucky then.

is that straight coolant you are using, premixed or concentrate? big different between the tooo straight ouf of the bottle...

what kind of motor is it? alloy or cast iron? makes a difference to how ot corrodes...

i would still like to see the coolant gallys and see if its been eatn out!

straight coolant no water its in a cast iron hb torana 4cyl engine.
