[urq] Evans Coolant

[AF]

So over 10 years ago we had this big thread about using Evans Coolant in
Audis. Someone did it, and used a modified expansion tank cap to allow
proper venting. Has anyone else had any experience with this product in
Audis? Is it less efficient as a heat transfer medium and therefore I
would be more likely to see higher coolant temps? The reason I ask is that
I'm seeing 102-106C in my V8 converted UrQ (front radiator clearance is at a
real premium if you install AC). I have been told that head warpage is not
likely until you see temps in the 150C range. Would Evans' product allow me
to run at up to 110C with no issues, because I'm guessing after a prolonged
steep climb in 100 degree ambient temps I might just see this at the head.
No, I'm not moving to Alaska to solve this problem ;-)

It's also flamable too......right?

Any thoughts would be greatly appreciated.
