135 @ 4800 in 4th with 2.73's is almost exactly right if you're running close to 26" tires.

The difference between full and 1/4 tank of gas is about 70 lbs. (10 gal.X7lbs=70lbs). Depends on how your car hooks as to how this affects et's. Of course, every bit you can reduce your race wt. will help if traction stays the same. Taking 70 lbs. off the rear part of the car could hurt traction and make you actually run a slower time if you spun too much. If you could still launch just as well, the less you weigh the better.

Presonally, I always take my spare and all tools out of the trunk and try to keep just enough gas to get home. This won't make a huge difference, but every little bit helps. You do have to launch well without too much spinning to get your best times though.
