Found it!

I found out the density altitude for 1100pm at Rockingham, NC (350') on 9/23. It was 79 degrees, 69 degree dew point, and 30.0 baro. The calculated density altitude was 1,900' above sea level.

This not good enough? lol

 

no it is..lol.. I was posting that when you tossed up your info. Hadn't refreshed in time to see your post.

 

I figured as much.

 

At Z Nationals this weekend, I ran the drag strip at the event 34 times. It was a good lesson on how to launch the car. At its peak, it was 95* out and the start line was very slick, especially for street tires. My first few times were 14.6-14.7 with 60's in the 2.6 range. However, I was able to get it down to a 14.2 with a 2.2 60'. I've run 13.9 at E-town in NJ so I know I can do better. Next time I'm at E-town, I hope to hit a 13.7 or so.

 

That is where I ran the 13.4 in the 2007. The conditions were very slippery then too.

Sorry I couldn't make it. Send some event pics, if you have any!

 

Its all about the driver and launching. Getting a 2.0 60ft and under on stock tires takes skills. Especially when its cold out.

 

were you at LARC?

 

Too many people are not factoring the track conditions.

Man, LACR is such a depressing track. Best I've ever seen a Z do their is 14.5, and thats with a perfect launch.

Track is very high in elevation, dusty, ... but its a good place to practice.

I'm all over the track conditions. I've ran in worse. His 60ft still made a big difference regardless of the weather.
