This is the first time I've ever raced at a track before, I raced at Byron Dragway in Byron IL. Elevation is 705 feet above sea level, the temp that day was 84 degrees with around a 72% humidity level.
I have a 2010 Impala LT that came factory with a LZE(3.5L) engine, some recent modifications I did was a LGD(3.9L) swap, 3.69 FDR and have a tune by Overkillmotorsports. I am running GMPP strut tower braces, GMPP thicker sway bars and have 2 week old Firestone Firehawk Wide Oval AS tires all around.
I did 5 runs that day and the best time I could get in the end was 15.618 1/4 mile at 88.1 mph, does this time sound about right with the mods I have?
R/T ... .665
60' ... 2.267
330 ... 6.514
1/8 ... 10.031
MPH ... 71.22
1000 ... 13.056
1/4 ... 15.618
MPH ... 88.01
I noticed that if I left traction control off I'd lose a 10th of a sec due to wheel spin, if I left the traction control on I'd get no wheel spin at all. I tried brake torquing it in the 2 final runs, it would rev to 1600rpm and I would get a slight amount of tire slip.
This was just a week after taking a trip to AL, I noticed on my way back to IL my car had developed a humming noise in the passanger front wheel area....I'm thinking its the half shaft as it goes away if I re-apply the gas pedal, I also wanted to note that my trans looked vary warned out when I was swapping around the gearing. Maybe a newer trans would get me better times?
