No thanks, I like it in my stone cave. 13lbs for 250 Deg or 30lbs for 270 Deg? I'll take door number 1, not sure my "stone age" copper radiator and old FE surge tank are ready for 30lbs. And long before my temp gauge reads 250 I'll all ready be freakin' out and taking action of some kind!
.....maybe if I was racing,,,,,,but then again, I'm not!
