I can smell more interesting mods in Bill'* future.

To clarify a couple points here, your water/coolant won't boil at 212°. It'* a sealed, pressurized system.

(and about 20-25 more horsepower)

I'm not talking about your coolant, why would you want that to boil???? Straight water won't boil in a 15psi system until 257*F, coolant which has a higher boiling point is around 280* or so. What I'm talking about is water that has gotten into your crankcase. This could be fuel from blowby, condensation, coolant that leaked in there from some sort of a leak, or any other way that water could get into the crankcase. It happens over time, and you want your engine to reach over 212* occasionally to boil this water. Water in the crankcase means no more bearings if there is enough. If it doesn't boil its probably not a big deal, especially if you change your oil often because a healthy engine should have very little water in there, however its still not a bad idea to let it heat up from time to time.
