Took the G8 to the track last night for the first time (for the car, not for me...), and was a bit disappointed, although the conditions sucked for going fast. Phoenix, AZ in July just isn't a place for good air!
Temps started out around 105 and decreased to the low 90's later in the night. DA's started around 5000 and ended up around 4000.
The car is 100% stock '09 G8, with the 19" Sport wheels and leather, 12k miles, 91oct.
I made 11 passes, and one thing I was impressed with was the consistency. I made 8 passes that fell between 14.30 and 14.37, right at 100 mph. This thing could definitely win bracket races!
All of these passes were made launching at around 12-1300, auto shifts in Sport mode, and holding 3rd through the traps. 60' times were consistently 2.18 - 2.20. Cool down was generally 20-30 minutes, although I did hot lap 3 passes to see what happened. ET was consistent, but MPH dropped ~ .5mph on the 2nd, and another .5 mph on the 3rd pass. No ice, and left the engine cover on. Ran it right off the street, didn't change tire pressures, or take anything out of the car, 1/2 tank.
Two passes were in the 14.40s where I was experimenting with manual shift, and leaving off idle.
Best pass was 14.17 @ 101.33, didn't do anything different??
I'm not a real fan of conversion/adjustment factors, as they have always seemed optimistic to me, but with air this bad, you've got to do something to make you feel better! :)
Adjusting for DA puts me ~13.50s @ 106, and that seems about right...
There was one other G8 there, an '08 with the 18's/all seasons and cloth interior, otherwise stock. He was icing the car between runs, and had the engine cover off. He was consistently 1-2 tenths quicker, and from looking at his slips, it was mostly in the 60ft, where he was .07-.1 quicker. I'm thinking the wheel/tire combo may have been a big part of the difference?
Anyway, what do you guys think, considering the shitty air?
(BTW, my Rotofab and HSRK are sitting in the garage just waiting for my tune to be emailed from Livernois...:headbang: )
