I've been running 80% distilled water and 20% Toyota red coolant with Red Line Water Wetter for more than 8 years for exactly this reason.
I stopped using Red Line Water Wetter because it caused a brown sludge to develop in the cooling system. Stopped using it and never had the sludge again.

What was your replacement interval, and what water / coolant ratio were you running? Were you using Type I or Type II coolant?

This happened with two of my vehicles. When I did the first coolant change of the factory fill (Which was several years old and had no sludge) I would mix 60/40 Toyota coolant (Red)/distilled water with the required amount of Water Wetter. With-in a year or so the brown sludge would form. This problem has been experienced by many others I know and they don't use it anymore, either. This is just a heads up, you may want to check your cooling system if you are using it.

I've been using Water Wetter since 1991 and never seen the brown sludge you describe. The earliest versions of it were a powder you had to dissolve in hot water. Also, I am confused about your mixture. You are saying 60/40 coolant/distilled. I don't know why you would ever use more than 50% coolant since it is a significantly inferior heat carrier. I've been using 80% distilled with 20% coolant for a very long time because it carries more heat per unit volume than anything but pure distilled. 20% is good to about +8F, and I don't live in a climate that cold. I could go on and on about the advantages of this mixture with a high pressure cap, but this thread is about race gas...
No. The boiling point really isn't the issue with it anyway. The danger really comes from the freezing point. Keep in mind that most race cars use straight water.
boiling point of water changes in a pressurized system anyway.
Unfortunately, the boiling point doesn't raise with a high pressure radiator cap nearly as much as it reduces with an 80 / 20 coolant solution. Even still, it isn't a problem if the rest of the cooling system is in good shape.
What is Purple Ice? If it is a similar product to RL WW, then I wouldn't bother messing with it if you aren't going to increase the water / antifreeze ratio.

I was talking about the red liquid (in the skinny bottle). I use 60% distilled water. Sorry for the confusion.
Colder plugs are good if you have very predictible climate. BRK7E Coper plugs work well and are gapped for .032
If you have variable climate then you can just go with the stock plugs. If you want to get higher octane out of your normal gas, you can just do water/meth injection good for 3 to 5 octane points .
Don't use water wetter, it leaves a sludge residue in the radiator
