Can somebody please give me some advice on what the hell is goin on? I took my car (01 ws6 m6 vert) to the track for the first time last week. I pulled of a whopping 13.71. This was on street tires, full interior, no weight reduction, and a whole lot of gas in the tank( i didnt plan on going that morn. when i gassed up). With a 2.1x 60 ft and a trap of 105 mph. This was the best of 4 runs. Now, I know alot of people will say driver error, not here. I have had sticks all my life. It took me a pass to nail the launch without blowing the tires off. I launched at about 2200 rpm, I didnt dump, I let out quickly and rolled into the throttle. I would say the 3 other passes were with a good launch. Now my question is this, does track temp, air humidity and quality play a big role in times? 3/4 of the way down the track my windows fogged up so much I couldnt not even see out of them! Just the lights of the car next to me. It was a hot evening, I'd say around 85 degrees. This really puzzles me cause i have a friend with a 99 a4 that runs 13.20's all day long. And everytime we have raced, whether from a dg or a roll, I've pulled him, every time, without fail. Is it the air humidity? It was a really muggy night. Should I go back and try to better myself? I dont understand the crappy time, especially with the street races I have pulled off. All of my friends said they thought for sure i would have pulled a really low 13 or high 12. And none of them were there(go figure).
