Hi I have an 2007 C6 Z51 with an A6, yestarday I did my first trials on the local 1/8 track.The car ran 10 runs with times between 8.6-8.8s, 60 ft 2,05-2,12. I had the traction control off and drove it in "S"
I got the best time when launching at 900-1100 rpm , with higher rpm I have problem with "traction" and loose some time to 60ft and1/8 even I I lower pressúre on rear wheels significant.

I have read quite much on this forum and it seems that many stock base C6 can run low 8 runs.

Is my 1/8 and 60 times realistic ones or should it be possible to come down to low 8s ?

my stock 05 auto car with stock tires ran consistent 8.1's in the 1/8 with a best ever 1.76 60ft

Yes, you can get to lower 8's, but probably not until you get cooler weather. An 1100 rpm launch works well if you can hook. With higher ambient temps, the computer is pulling timing, which is most of the reason your current times are suffering.

What is the altitude of the track? Air density plays a big part in overall engine power.


Here's a link that can maybe help give you an idea.

Oh wait ... it is for 1/4 mile times, not 1/8. Either way, might give you a basic idea of how to adjust your 1/8mile times locally to what some others might also be seeing.
