Well first off I'm mad at myself. I couldn't launch the car to save my life. It was either bog or boil. Then the track prep was crap, every time I hit 2nd gear it would break em loose again. I'm very happy with the cars performance though. It runs very strong, if I can get my 60' time down another 2 tenths it will be in the low 13's its definitely a driver issue at the moment

But anyways, here is my best pass of the night. Ironically my best run in my Cobalt SS/SC had the same exact 60' time... I'll post that for a comparison. I'll see about getting this time slip scanned one day soon to added to the 1/4 time board.


350Z
60'- 2.145
330'- 5.928
1/8- 8.990
1/8 mph- 80.45
1000'- 11.585
1/4- 13.793
1/4 mph- 102.2

Cobalts best
60'- 2.145
330'- 5.892
1/8- 8.948
1/8 mph- 79.85
1000'- 11.597
1/4- 13.811
1/4 mph- 103.73

 

The numbers are good. Everyone has room for improvement.

 

Good times for both cars.

I love to analyze time slips:
Z
8.990 - first 1/8 @ 80.45 MPH
4.803 - last 1/8 + 21.75 MPH

Cobalt
8.948 - first 1/8 @ 79.85
4.893 - last 1/8 + 23.9 MPH


All though the Cobalt beat the Z in the first half of the track, the Z made it up in the last half. But the Cobalt crossed the line 1.5 MPH quicker. And although the Cobalt was faster to the first 1/8 and gained more MPH on the last 1/8 it still lost... numbers are amazing.

 

Yeah I thought it was pretty neat as well. The Cobalt had great top end, just super hard to launch. That was the best 60' I got out of the Cobalt. Not bad for the stock tires on that car. Now I just need to get the Z's 60' down to the 1.9 to 2.0 area and I'll be golden.

 

Good job!

Were you doing a couple of brief burn outs first?

 

Not bad! Practice makes perfect..

 

I was doing a quick burnout to knock the dirt off the tires. No smoke show or anything.

Thank you sir. I'll definitely be practicing.

 

Where is Keystone Heights ?? What track did you run at?

 

Keystone is like right between Gainesville and Jacksonville. I was at Gainesville Raceway.

 

I was looking into this a bit more today. I played with the DA calculator on Dragtimes.com and came up with interesting results. I have the timeslips that show times and dates so the info is pretty accurate. Basically the Z had slightly worse conditions but still a bit faster.

When I made that pass in the Cobalt the conditions were as follows

Gainesville Raceway Elevation 147ft, December 1 2007
|1:53 PM| |73.0 F| |59 % humidity| |30.25 in|

Density Altitude: 855 feet
Relative Density: 97.52 %

The Z's conditions

Gainesville Raceway Elevation 147ft, October 25 2008
|5:53 PM| |72.0 F| |61 % humidity| |29.94 in|

Density Altitude: 1211 feet
Relative Density: 96.5 %

 

Nice runs. Seems most HR Zs run about 13.7-13.8... That seems to be the average.

 

Yeah, it seems to be but I think there is a few more tenths to be had from mine. I'm not to proud of that 2.145 60'. If I knock it down some more I think I can squeak a 13.3 or so out of it.

 

For every tenth you gain in the 60' you'll get 2 tenths in the 1/4mile. So you'll need a 1.9x 60' to run 13.3. Not impossible, but not easy either.

 

 

very true, but I was able to get the Cobalt down to consistent 2.1 60's on the stock tires so I have faith in my abilities to get the Z down to the 1.9 area with some practice.
