My best was a 13.8 @ 103 with a 60' of 2.0. This run was on 23rd of June so imagine all the heat and humidity of Texas during summer.
Dyno's have correction factors put in to adjust to weather conditions . Very nice times . The 500lb's is a big factor even with a 100 more hp than you .

Also...it makes a BIG diff on how much VHT [or what ever its called ] the track puts down and how far down the launch pad they go with it .

You can use one of the calculators here for comparison purposes:

Come out to West Texas for a real letdown. Take the 100 degree heat and add in 3000ft elevation. My car with popcharger and Injen SES ran 15.3 in July of 04. I dont even bother going to the track unless its winter time and its in the 50s. Best time now in cooler weather at the same elevation is 14.3.

The price of beans in china confused me, that's all.

Can you post up the timeslip for the 14.3?

You should've asked then.. the elevation is about 500' and the pressure was 30.00. Happy?

well some of the tracks are down hill . I think they are allowed 6 degree's [ not sure ] And it has to help some with times and speed

Ill have to find it. It was awhile ago. I can look for it when I get home though. Is there something special about that run?

Off the top of my head:

60ft 2.0x
1/8 9.2 @ ??
1/4 14.33 @ 98.7

I just wanted to compare it with my own runs that are 14.33ish and my best ones to see how much the "west texas" weather is affecting a more modded Z than mine.

I'm never happy.

You didn't explain why you listed the weather for your dyno run like it meant something??

I also already knew the elevation around the dallas area (was that at texas motorplex by any chance?)

Built in 1986, The Texas Motorplex has been the place of many drag racing milestones and world record performances. Ever since Darrell Gwynn christened the first all-concrete quarter-mile, national records and speed milestones have been commonplace at Texas Motorplex.
You still didn't list the relevant weather variables for the actual 1/4 run. The mean temp. on june 23rd was 84 degrees and the max temp for that day was 91, so it's kinda hard for me to believe it was a scorching 103.

OK, cool. I'll look for it when I get home.

Now you run at tracks with 15,000 ft elevation, with a 45 degree incline, and a 50mph headwind, right?

Best driver ever!

I'll asnwer your questions in order.

The reason why I included the weather for my dyno date was because everybody seemed to dyno so much less than what they should have. So I figured even though it was SAE corrected, the correction factor of 1.05 wasn't enough. The TT was to dyno around 440 whp but only got 407.

If you already know the elevation of the TX area, why even bother to ask? Think I'm gonna lie? And yes it was Texas Motorplex.

As for the relevant weather variables for the 1/4 mile run, you're right I didn't listed everything. Where in my post does it say that it was a "scorching 103?" The 103 is the trap speed in mph.. not degrees fahrenheit. The specific variables for that date, as I have recorded, was as follows:
temperature: 88°
humidity: 55%
pressure: 30.00
track elevation: ~500

Any other variables you want or nonsense you wanna keep talking about?
