Acceleration Tests: 2005 CTS 3.6L 0-60 mph

Car journal can be found here: http://caddyinfo.ipbhost.com/index.php?showtopic=39 for comments.
Thanks, Bruce
Modifications:
    * Corsa Cat-back system
    * Volant Cold Air Intake.

Almost empty of fuel, 14 gallons missing (87 lbs).   Empty to Full on my 96 STS made 0.15s difference.  CTS was cold from sitting for 8 hours.  Temp 59F vs 73F should give .15s benefit.

Expectation:  previous best 6.25s - .15s fuel - .15s temp = under 6 seconds.

Note:  the stock CTS 3.6L Automatic does 0-60mph in approximately 6.4-6.6 sec.

For Run 1, I forgot to reset the weight on the AP22.  This does not effect times, but inflates the hp slightly.  So I have greyed out the hp for Run 1.  Prior to Run 2, I reset the weight to the proper value assuming 3,694 lb car, plus driver wt, minus fuel missing weight.


Result:  My first under 6 second run! Was having such fun I ran to 80 by mistake.

Top of 2nd gear is at 66mph - ish , so I am surprised at a max hp reading of 221 hp at 78.4 mph.

216 whp / .8 transmission losses = 270 hp at the crank.

221 whp would be 276 hp /shrug
