A nicely tuned modded Z will give all the power you need. I lose respect for tuner/racer who has to use NO2 to get into 10s or dyno crazy HP. There was one time when I was racing a the dragstrip, this WS6 was running mid 11s all day long. Lots of other drag racers gave props to his TA....until we found out that he ran a shitload of NO2 :(
