Ok so im toying with an idea at the moment, focused around using an air-cooled heat exchanger similar to your standard oil coolers from repco.

I am going to pump water from a reservoir through a cooler then up-to bits susceptible to heat soak in an engine bay.

Initially i was going to just use water, but i want this little system to still be "usefull" for long periods of time

What other readily available liquids with the same SG of water are there around that have better cooling properties?.... Other than coolant, which is pretty much only a rust inhibitor/anti boil anyway.

coolant doesnt transfer heat as well as straight water.

Are there automotive oil-based coolants available like they use in electronics?

Distilled water with an anti corrode will be your best bet.

Good enough for nuclear power stations, good enough for you.

Why not look at a CryO2 setup? They do fuel rail coolers and all.

Cheers for the reply's you lot.

Beare in mind the fluid needs to have the same Sg as water or marginally heavier. I need to keep the flow rate up.

Fluid has to be Inert, no way am i gonna pump something explosive around hot things close to the throttle body lol

What about Glycerol?

What do you think is in coolant?
