Yes but you're not taking into consideration that you're talking dual power adders now. Also his car should be making around 450+rwhp. The safe limit on those cars is about 550rwhp.
You act like no one has ever blown a motor in an 03 with nitrous because numerous people have and especailly with a 200shot you're just asking for trouble. People that run nitrous on their cars (stock motor) run a small shot 50-75 while some go 100 but they also have fuel upgrades and are still pushing the limits of reliability.
This wasn't some one I read about on the internet this was a closef riend who blew his motor. He had a killer tune on it and I knew his car inside and out, nothing was half assed on the car.
