I'm not sure I understand the logic of going to high pressure radiator caps.

A 13lb cap will raise the boiling point of water to about 250 Deg F. So more pressure will raise the boiling point higher, but IF you get to 250 gimme a break! Something is way wrong all ready!

Less pressure means less wear and tear on hoses, surge tanks, radiators etc. 13 is about as high as I will go with MY systems.
