9.899 660' time isn't much better than my 9.987 even though you have 7 more MPH on me at that point. Personally, I wouldn't hit the nitrous until after you've shifted into 2nd. That will reduce the chance of wheel spin/hop greatly.

As everyone else said, a good 60' will go a long way. My current best is a 2.19, but I've consistantly been in the 2.2s with the current drag radial setup. Even on street tires, I'm in the 2.3s all day long.

If you have to feather the throttle on the launch and only rev to 3k, then there's something wrong with the track you go to. OR...there's a lot of people running street tires that are abusing the launch pad. The more street tires that run on a drag strip the less rubber is left on the launch pad.
