Pontiac Pavement Pounders Shootout - Norwalk Raceway Park Part 3
Owner Bio: Pat Lavanty
For 26-year-old Pat, this '01 Grand Am GT is the first new car he's owned. He's been modifying and racing it since he first bought it and recalls his favorite moments in it: "Dyno day with DHP and the install and testing of the supercharger." This chef bought the Grand Am for its styling, but now the performance is just as enticing. Regarding outside distractions, "I really don't have any other interests," Pat says. "I like to cook and make my Grand Am quicker." | STRIP TUNING LOG | | Run | Tuning | Launch RPM | Shift Point | 60-FT | 1/8 E.T./MPH | 1/4 E.T./MPH | | 1 | 20-deg timing, 22 psi in front tires | 1,600 | 6,100 | 2.36 | 9.36/82.24 | 14.31/99.06 | | 2 | Same, 20 psi | 1,700 | 6,100 | 2.31 | 9.16/82.80 | 14.06/100.23 | | 3 | Same | 1,700 | 6,100 | 2.34 | 9.16/82.81 | 14.06/100.01 | | 4 | 19-deg, 18 psi | 2,000 | 6,100 | 2.12 | 8.97/82.44 | 13.89/99.72 | | BEST PASS CORRECTED | 13.22/104.77 | | 5 | Same | 2,100 | 6,100 | 2.27 | 9.10/82.59 | 14.02/99.54 | | The five most important runs are listed in the order they occurred. | | Run Notes: 1) Lazy launch, low boost due to belt slip (4 psi); 2) Same; 3) Same; 4) Same but better launch. |
