New Personal best 1/4 mile time
Conditions today were awesome at Pacific Raceways for an afternoon of drag racing. I ran a personal best the first time down the track. Couldn't seem to repeat my great 60' time again so I never ran a faster elapsed time.
My best elapsed: 12.455 @ 117.43 w/ 2.071 60'
Fastest trap: 12.614 @ 119.16 w/ 2.181 60'
I'm very happy with the way the car is running right now. A tiny tweak of this tune and it'll be perfect.
I ran 5 times. I never lost one race - in fact, it was never even close. The closest race was against a bolt-on 300C SRT8. I put a good 8 cars on him.
Here's a video of the 12.4 run from inside the car...

Were you always running 7psi? I thought you were at 5psi?

Nice time! You should put some drag radials on and shoot for 11s! Time to re-enforce the back end...
I got to run my '06 GTO on Speed Channel's "Pass Time" this past Saturday. (Watch for the red goat on an episode in June!). There was a CTS-V out there that ran 12s and he was not supercharged.

117mph trapping is not bad at all which means the car is strong rolling.
Is CTS-V THAT heavy? Because naturally aspirated auto LS2 GTO with that power run mid-low 11s and DR. I know autos are fastest in GTO but just surprised you didn't break into 11s. Maybe elevation and/or wheel hop?

I've heard a lot about the CTS-V rear ends blowing up when people get to the HP that you are at.
I say tub it, put in a 9" ford rear with posi solid axles, sub-frame connectors, slicks, and runs some 10s with the power you have![Big Grin](https://acurazine.com/forums/images/smilies/biggrin.gif)
Put some air under the front tires on launch

It's actually rare that the rears break. What typically happens are the gears start making a loud howl. Really annoying in a Caddy.
There's only one aftermarket solution out there right now and it costs about $10k installled. I'd prefer to keep the IRS intact since I use the car for road course and auto-x as well. Drag racing is just kind of a 'filler'.
