My friends brother has a civic hatchback. He has 70 shot nos. But the thing is he put it so that once his rpm guage goes past 3000 rpm it theres a red bar that if the rpm meter hits it the nos just keeps spraying. I told him he was stupid enough to do so becuase i would think his engine would blow up or just die. I was wondering what you guyz think because I dont wanna race him for belief his car is gonna blow up next to mine.
