What are you guys elevation/altitude with your 1/4 mile times. I'm at 3241 so I'm not sure what to expect.

 

Some racers run 13.70 seconds while others 14.70. So its difficult to expect anything. Why not run, then adjust your ET using this chart:

Mods and times in sig. Elevation at my track is ~250ft above sea level.

 

just curious what time to expect from my z in the 1/4 & the 1/8? it is bone stock w/6spd

 

At that altitude expect to run a 14.5@97mph at best.

 

San Antonio Raceway is 600ft. 12.98@106.11 is my best to date.

 

who is that directed at? me?

I went and the best I got was 14.7. I think a lot of it had to do with my bad driving, lots of wheel spin and 60' times of 2.5-3.3 . I plan on going again soon for more practice.

 

Using Davidv's table, I took your altitude and figured a best of 13.9@101mph to come up with the 14.5@97. A 14.7 at your altitude with a 2.5+ 60' is actually really good.

 

Sweet, sorta good to know. I am planning on going again on Sunday to see if I can improve that any. I'll let you guys know how I do. Thanks Integrity.

 

Went to the track last night. I was dissappointed my best was a 14.3 with 2.3 60'.
Then again my girl was riding with me, and OSW is slicker than Hell.
The other Z there, it was his first time too, ran a 16.00. ???

 

yah taht was prbably me i got a bad launch the first time because of driving through that wet **** and not spinning my tires. .. the reciept said I ran a 14.5@88 which is bull****...no d/rspct but i doubt u ran a 14.3 with ur gurl in ur car,stock, those first times were fukked up.the second time i feathered the clutch and did/nt really launch and ran a 15.02 with bad shifting seemed right. i need practice it was my first time though...i destroyed my boyz n/a supra though

 

So I went to the strip again today. Did better. Here's my best run...

Elevation: 3250 ft.
Temp: 63F

R/T: .362
60': 2.219
330: 6.172
1/8: 9.394
MPH: 77.29
1000: 12.141
1/4: 14.45
MPH: 98.0

 

6.64@215mph in 1/4 mile (pro car) part of performance motorsports race team

 

Spot me 7.1 seconds and I race ya.

 

I do believe it is more than just track elevation that affects car's performance. Even though my local track is only 435 ft above sea level, our density altitude is well above 3k ft during the summer due to heat/air pressure/dew point. Because of that, I use density altitude calculation to figure out what my time would be with sea level altitude rather than just using altitude correction factors.
