| I have used a 19% for a couple of years in my 'track only' MCS. I have to say you are right about eventual failure but its a long way off for most people. Its hobgobble about not tracking with a 19, most people do....or at least those with decent times if not a 17%.
As for the cavitation, i'm figuring out how to install a standalone electric water pump with temp adjustment. Adding this to JCW SC I bought so should perform without a problem.
I do have a backup SC and head if things go wrong but even with my rev-limiter based driving I expect a good 30-40,000 miles from it. Things like air ducts can slow down the failure but things do get very hot under there. But unless your a clown who does'nt realise a car needs to be cooled every ten or so laps then you probably will blow the SC with a 19%.
