We've run the 1/2 mile and mile in Nebraska since 2002.
Run it in Drive until it stops pulling or 115, then manually shift to OD.
Otherwhise it will shift to OD early, the car will bog and spend an 1/8 mile trying to recover.
Stock Vipers, Corvettes, etc. only run 130-140 in the 1/2 mile. A stock GN should at least run 125 (115 - 119 if you leave it in OD).
FAST!!! cars run 150+ in the 1/2 mile.
The fastest 1/2 mile Car at Nebraska ran 177 (A TT viper with 1000+ RWHP)

The fastest cars in the Mile in 2007 was a Misubishi Evo 6 running 40 psi of boost that ran 215.9. Ron Adee was 2nd at 215.1 with his tube frame, carbon bodied twin turbo big block chevy powered Viper Road race car.
My 502 Pontiac 2+2 runs about 136 in the 1/2 mile and 160 in the mile, but I hope to run 140 in the 1/2 mile my TTA in 2008 (2.7:1 rear axle and running the 1/2 mile in Drive).
