2016 C6 of the Year Finalist
Default My First Drag Race

Actually, not exactly my first, but my first since 1964 and the first with my 2013 GS A6.

The car is entirely stock with the possible exception of the NPP exhaust which I ran open. The street tires were inflated a few weeks ago to 30 PSI cold and I did not adjust them for the race. The below race slips tell me that my reaction time was improving dramatically, but I definitely need to stop spinning so much rubber at the starting line. Next time I race, I'll deflate my tires to 25 PSI warm. Other than that, I have no plans to make any mods to the car to improve my race times/speeds.

I tried it both ways, no noticeable difference either way.

If you're running runflats, don't bother deflating your tires. The sidewall doesn't flex like a traditional tire when deflated.

Is it because of the temperature that the car ran that slow? I thought these cars were supposed to run in the 12's.

Upper to mid 12's is about right for stock 2008+ C6, depending on the gearing.

A decent 60' would put it close to 12's and the mph indicates that also.
He said there was a lot of wheel spin.

Both the track elevation and air temps affect his times. He is around 7,500 ft for density altitude

not bad times, but certainly room for improvement and you'll have fun getting there. Leave air pressure around 28-30 for stock run flats, won't make much difference. Work on launching easier to reduce tire spin and then rolling into the gas quickly off the line.

I dropped my times from consistent 12.5 to 12.17 with my completely stock 2008 A6 with Goodyear run flats, but I'm in Dallas and elevation is 500ft and temps were 70's.

Also, if you have not tried already, run with 1/4 tank or less. That also made a huge difference for me.

My car is stock and will stay that way, not into modding it, but I may try some drag radials to get it down to the 11's just for kicks.

Have fun!

That's what I would have expected but I am sure the elevation , wheel spin and elevation had a lot to do with it

I filled the tank on the way to the track thinking the extra weight would help with traction, obviously a mistake!

Also in my defense - 71 year old newbie racer here!

Me too - Not expecting much in performance for a few months. I reloaded my factory tune about 4 weeks ago. Just idling through Hades.

He will get there, just takes some practice.
Some good launching advice on the forum.
My car bone stock, tires at full psi, ran 12.49@115.
That happened the second time i went to the track.

No offense to the OP, but a C-6 should be turning at worst in the low 13's, and thats with a relatively inexperienced driver at the helm. A stock C-6 should be turning in the high to mid 12's with all things being "normal" and an experienced driver ....

Looks like you had a great time with your car. Good for you. I will say this and all in fun the first reaction time was an asleep at the wheel moment. Supercharger next???? I gave up drag racing a few years back after several decades of hard launches and never being home on weekends. I have been tempted to run my '13 GS but it wouldn't be the same for me. I do want to try a road course. Good luck and glad you are taking it to the track and not the street.

Considering that the DA was in the 5400' range and your 60' launch time was fairly slow from spinning, I think you did OK. If you correct the second run to 0 DA, it would be 12.8x @ 115. I've never been able to run 10's there at that elevation, but can in Phoenix.

Yup ..... Using the 'Drag Times' density altitude calculator for Southwestern Raceway (Dragway) in Tucson with the weather data for the time and date the OP posted, his DA was 5781 feet.

The SAE 'Corected" ET and MPH was:

12.81 @ 115.97 mph
