For the same power level, ranked by life expectancy (best = 1st)
1. turbo, supercharge
2. NA
3. nitrous

Major killers:
1. heavy piston
2. high rpm
Remember, inertial load @ TDC exhaust is what breaks rods, and it increases as the square of the rpm - 8,000 is not 14% more than 7,000 (8,000 ÷ 7,000) but 30% more (8,000^2 ÷ 7,000 ^ 2)
