How much nitrous will engine handle? It has a stock bottom end. I do have HT0 plugs. I would really like to put a 150 on it. How long would it last? With the parts i've added and a little more weight reduction like 250 more out. I was really wanting to try for a 10.90... What 60 would i have to achieve on a car with 440rwhp and 500tq to run a 10.90?
