New Car Owner w/ questions

[97snakedriver]

1. If you have the 17" wheels with the Z rated tires then there is no top speed limiter, and I would guess a 2000 GT would top out somewhere around 150 or high 140s with a long enough (ie LONG) run up.

2. There's the great running debate about rather or not to remove the intake snorkle. But with just a K&N drop in filter I would not expect any significant gain. A hp? Not enough to notice. Although it is nice to not have to replace the filter.

3. What's the manual say? Mid-grade? As long as its stock there isn't any advantage to running higher then the recomended octane. If you were to get a Steeda timing adjuster then there would be a significant advantage to running with a higher octane.
