I just ran the quarter mile at Englishtown Raceway in NJ. (60) was2.294,(330)6.528,(1/8)10.038,(MPH)71.62,(1000)13.056,(1/4)15.644,(MPH)86.38(r/t)5.25

What year is your grand am. what motor? auto/manual?

im hitting 100 mph in 14 seconds with my 2000 se LA1 207 ci 3400 v6 Natural Aspiration.
I need to get clocked properly at a trac so i can have detailed bragging rights , but for now i am just getting my freinds to watch and clock with a stop watch using my TPS (throttle position sensor) to tell when i hit the gas then they watch my odometer for 400 meters. We tried it several times in a row and the times are consistant.
