tire preasure was left at 25psi the whole night as the et streets felt very stable at 120+ speeds. coolant temps were between 205-215 on all runs. track prep was ok?-i guess. NO 4TH GEAR SHIFTS! all runs were thru the traps in 3rd at about 7k. i have made only a total of 8 passes in this car & this is the first stick car i have run at the track. car is very inconsistent on the launch & needs a good cool down to get a good mph. but for mid june in vegas(+4500ft) in a bonestock z with tire, i'm very happy with 123.3mph.-the best my bolt-on a6 could do in good weather was 12.49@113.5

fwiw- another bonestock zo6 on drag radials went an average of 12.40@118mph

Nice passes!

NIce driving. That cool down makes a big difference. It's hard to get that 60 ft. below 2 sec in this car. I've only been able to do it once in 13 runs.

Nice numbers for Vegas.


I was up in Fontana 3 weeks ago and ran my 08 A6.
The heat was on that day, 103F and the track official said the DA was 4500ft.
The car went 12.37@115 on runflats.

I don't do 1/4 mi runs so my guess is those are good #'s. It's always nice to see Z on the track. Sounds like a lot of fun.

Nice improvements made during the day! Anytime your ET is going down during a track day it's a positive.

If you're not spinning then don't lower your tire pressures, although 25 seems a bit too high.

At 100*, it would take MANY hours to cool these cars down to ideal operating temps....it SUCKS!

Launching this car GOOD is difficult, as the clutch release & throttle squeeze need to be timed PERFECTLY for best results. Practice & feel are the best way to accomplish this.
1st burnout of the day on ET Streets should be a good one, then smaller ones to first smoke the rest of the day.

A bog off the launch in a stock powered,stock clutch C6Z is unavoidable. That's why I personally feel the ET Streets are too much tire for drag racing a C6Z. I almost NEVER spin on the launch using my MT ET street drag radials! Other opinions may vary.

Very nice. Now I can't wait to see what happens when your car is Lethalized. Cam package shipped out today.
