I can't be much help, but I did run it in my Paxton SRT-10 with wet liners for about a year.
First, you have to drain the block and flush it, let it dry (eliminate all of the water) then pour in the Evans Cool. It does take a 17 lb pressure cap, which is stock on our cars, so no problems. It also has a much higher boiling point than normal coolant and is supposed to all but eliminate rust. It is very expensive compared to ther coolants.
I had cooling system issues that I thought were caused by the Evans Cool as my coolant temperatures became quite a bit higher after its installation. I installed a new larger radiator, a new oil cooler, had DC turn my fan on earlier, then I later found that the new thermostat that was installed during the coolant change was not opening all the way, ARGH!
I went back to normal "orange" coolant" with two pints of "super cool" rust resistant coolant additive after replacing the thermostat and all is now very good.
I would probably not switch back to it due to its cost and little if any perceived additional benefit.
