You can save yourself some work;

Evans is mostly a mix of ethylene and polypropylene glycols, not significantly different than your regular antifreeze mixes, minus the absence of water. Straight water has a higher heat capacity than Evans or water + Antifreeze mixes. Glycols are used to provide freeze protection and antifreeze mixes include corrosion inhibitors. The boiling point of glycols is higher than water (or mixtures) so yes Evans can claim the vehicle won't boil over with water less coolant, but think about that for a moment... the engine is still running at that temperature, just the coolant isn't boiling, so in reality your fail safe of steam / boiling over to tell you have a problem has been eliminated! Damage is still occurring to your engine from running at elevated temperature! Evans evens say on their website the gauge temp may be higher!
IMO Evans is basically a great marketing exercise to alleviate you from some of your wallet contents and nothing more. If you have an inherent over heating problem, spend your $$ to fix that by adding more cooling capacity (larger or more efficient radiator), move more coolant around (high volume water pump or overdrive pulley) etc., but Evans doesn't fix anything, it's a band aid approach that helps mask it!
Evans should not be used in a vehicle to be used on track for the same reasons traditional glycols are not recommended as they leave a 'oily' slick residue if spilled.
On the discussion of aluminum vs. copper I run Fluidyine aluminum radiators, but it is worth mentioning that many aluminum radiator failures are due to simple galvanic corrosion, thus it is well worth using a sacrificial lead anode in a mixed metals cooling system.

Never heard of that risk but I will test the ignition temp of the stuff and report back
