I think if you search a little on some of the larger boards such as modulardepot.com and corral.net you will find those who have burned pistons from running nitrous (and superchargers, and turbos etc.).
thats kind of generalized. i dont think you can come to the conclusion that the motor will be safe. there have been plenty of motors let go from aftermarket parts less dangerous than a power adder such as nitrous. an off the shelf chip can damage a motor, but you dont think an untuned nitrous kit will?
there have also been cars tuned up to and past 450 rwhp on stock shortblocks that have lasted, but i would be willing to bet that these cars are in the minority. if you are running a 150 shot without any kind of a tune, you are living on borrowed time.
the only reason people have "burned a piston" is because they ran out of fuel or their tune was out of wack to begin with. the reason you can hurt a motor with a chip is the same as above, they didn't have enough fuel in the tune.
NOS, ZEX and the like do a LOT of testing with absolutely bone stock cars, not a single thing done to them. i have a personal friend that worked at NOS for a number of years and did their testing. he has told me numerous times about their testing and how they would spray the ever loving christ out of cars and not change one single thing on the tune and it wouldn't run lean. nitrous kits are designed to compensate for the nitrous with fuel, be it through your injectors or adding fuel through the nozzle. it isn't a guessing game, they have it down to a science. the amount of fuel that is required for the nitrous is all done either through the brain of the kit or the fuel jet that goes with the correlating nitrous jet on a wet kit.
so i repeat, YOU WILL NOT HURT THE MOTOR! unless you are running barely within the limits of your current fuel system, there will be absolutely no problem.
also, i have a friend that ran for 3 years on a 215 shot on his mustang with zero tune... but you're right, it finally came apart. he got tired of it and put a turbo on it and went 10.30s. stock short block. borrowed time? lol
oh yea i forgot to add, he went 10.30s without a tune.
