low mph in the quarter
I have a 2006 c6 aotomatic car and went to the track and only ran a 13.1 @ 106 car seems to be pulling fairly hard just wondering if I could be experiencing a tranny slip that I cant feel or just what the deal is.I have always heard these cars ran in teens somewhere. Just bought the car used it has 30000 miles and like I said there seems to be no problem with motor feels very torquey.

im sure thats about right for the car because it was probably hot, when its warm outside and the engine gets hot then it starts pullin timing slowing you down. my car when i 1st got it ran 12.8/9 @110 in the summer heat but if i hot lapped it and got the car hot then my mph started to drop off down to 106 after about 3 hot laps.
your car should be able to run in the mid to low 12s with cool air with decent traction.
good luck

If you ran in July/August then it's totally possible when we see days with the temp over 100 and humidity 70% or higher.
I ran my car at baytown (HRP....now RPW) around then when I was stock and ran between 109-111. That same pass in cooler air was 113-114mph

The stock timing table pulls 3* of advance at 86*. If you sit in the staging lanes with the engine idling or even off, hood down the IAT will go up real quickly pullng even more timing. Just a short time idling in 80* ambient my IAT rose to 118* at launch. Big loss of power. I was down 8 mph on that pass from a pass I made in cooler air.
Even on my 11.22@125.83mph pass with 43* ambient my IAT was up to 84* at launch. Kept the hood open as long as I could, which really helps, but still rose that high.

That is why I won't go near HRP(RPR or whatever crap it is now) in the summer. No need to put the strain on the car.

Trust me I've been doing this for over 40 years from a Honda Civic to a NHRA D/Altered that ran 8.03 @ 166 mph !
A bad 60' might hurt your MPH if it was caused by "BOG" but if it was caused by spinning, your MPH should still be good, but you will have a bad ET !
