Density of Gasoline: 6.073 lbs/gal
B13 Gas Tank Volume: 11.2 gal
6.073 x 11.2 = full tank weight = 68 lbs
Actual: 75% of 68 lbs = 51 lbs in the car
If you weigh it at 1/4 tank: 17 lbs. Difference: 34 lbs.
IIRC, the rule of thumb is 100 lbs knocks .1 of a sec...Am I right?
With that said, and all things being equal, you could of knocked off 0.034 sec off your 1320.
Congrats brah!
