Cheapest ways to increase power

Road/Rage said

I work in an high performance race engine building shop. I see first hand what nitrus does to pistons. Its a cheap way out for lack of building knowledge on how to build a naturally aspirated engine with high HP! The nitrus is cheap the set up and plumbing is not! Im not against it but there are better ways!

Every engine i have seen that was fried by nitrous was the result of not reducing total advance, wrong heat range spark plugs, and not using an air/fuel ratio gauge, and not testing and tuning. The ones i saw were 150 or less, i have no knowledge of huge shots. During WW2 the US and the German
Sucessfully used nitrous on high altitude aircraft. Some of those engines produced 1500-2000 horsepower.
