It seems as though a very basic principle is being overlooked here. Hypothetically speaking, if you have enough intercooling efficiency and/or high enough octane fuel to take detonation out of the picture, and have all the fuel supply you ever need, you cannot run an infinite amount of boost and get an infinite amount of power. Components will brake simply due to lack of strength to handle the combustion chamber pressures. Most of us know that the weakest link on our stock bottom end are our ring lands. They simply can't handle x number of horsepower.

If you take a stock bottom end already being abused by the extra power of 7 compressed lbs of air and spray that with a 75 hp (N/A rating) shot of nitrous, which the cooling effect on the forced compressed air raises even further, say around 125 hp total from the spray your weak cast pistons are gonna brake! You don't have to have extreme temperatures to destroy things.
