A warning about Evans Waterless Coolants

The one thing nobody has talked about, is fuel mileage. I Know that for most guys this is not a biggie,but I used to drive my car all year as a DD, so it was an issue for me.I found that running a minimum water temp of 205*, allowed me to lean the cruise circuit out pretty good.But that didn't allow much room for emergencies. That led me to what YR mentioned, A large-area rad and a hi-flow pump.Yeah I had to cut out my core-support. To that I added a 7-blade fan on a reliable thermostatic clutch, and a hi-flo stat. So I ended up with a cooling system temp that is rock-solid at 205*. Knowing that it was reliable now, I dropped the pressure to 7psi,the minimum I could find.That was 15 years ago. All the hoses are still on there including the top one which was used when I slapped it on there. I can run any antifreeze ratio I want, or straight water,it matters not.
I also found that the engine seemed to make the same amount of power with timing anywhere between 36 to 32 degrees(aluminum heads). I didn't know what to make of this for quite some time, maybe several years. Then one day I ran across some info from a dyno shop that mentioned this very thing, as to aluminum heads.Up to that point I had chalked it up to tight-quench theory(mine was .035).
But getting back to fuel mileage.During the tuning stage, I found with a conservative mechanical curve and a ton of Vacuum advance,I could take out a lot of fuel, pretty much everywhere except at WOT.This made her very snappy. I won't tell you what kind of mileage I eventually got, cuz you might think me a liar. Everyone does.And besides, the only numbers I remember now, are the ones where I was running a double overdrive,and that won't be a fair number to reveal, cuz, who runs that?
Point of story:Once your cooling system can run a reliable rock-solid temperature, you have to retune for that new temp. That means a careful choreography of timing and fueling.There is no reason anymore to run fat and lazy all the time,just in case the needle starts climbing.
I guess that doesn't have much to do with Evans, other than I don't need it.
