1/4 mile runs in the CL65 today....
I finally hit the track in the CL65 and it performed as expected.
Anyway, the car ran 11.67, 11.51, and 11.58. The first run was slower from high air temps. The third isn't a 11.4 because I choked.
Hopefully with a tune the car will run some 11.0's. I was in the right lane on all the slips.
Lesson Learned. This won't happen again.

And that was stock other than rear tires/wheels right? Any idea what the DA was or temperature?
It looks like my first trip to the track is going to be on street tires, but with a couple mods already traction is going to be a challenge. We're you stalling it up on the launch or leaving off of idle?

Car is bone stock except for the 265/40-18 MT ET Streets. All runs in Dyno mode.
- Run 1, idle lauch with 19 psi in the rear tires
- Run 2, around 1,100 launch and 18 psi in the rear tires
- Run 3, around 1,100 launch and 18 psi in the rear tires
I just confirmed the DA for the 11.51 run was 531'. Really no point in checking the others.

0-60 time and American style 1/4th mile drag racing significantly understate the performance ability of CL65s due to weight to rear tire footprint and weight distribution.
As a CL65 isn't going to do wheelies on 10.5 street tires, I suspect adding some weigh at the very rear (such as weights under the rear bumper cover) while any possible weight lightening forward (few options there) would increase 0-60 and quarter mile time with enhanced traction at launch. Since the car can not possibly use all its torque at launch, it is possible putting some weigh all the way back could allow faster launching, with plenty of torque and HP down the track.
Where a CL65 proves its stuff is in 1 kilometer straight line racing Russia style. However, the value of CL65s is realized when already rolling such in passing, freeway merging and sliding into small openings in the fast lane from the slow lane.

Fortunately they tiny rock ticks don't jump out at you on a light colored car. They are murder on a dark colored one.
Oh, and congrats on your consistency between the 3 runs.

As for the color, that's why I buy light colored cars. I can't imagine owning a black CL. Way too much work to keep clean for me. My wife just had to have a black VW CC, and I've not seen it look really clean but maybe 5 times in the past 6 months. Every imperfection is cleary visible.

it looks like kizmet was at work in bowling green yesterday. did you happen to notice that your racing # is the same as your trap speed on your very first pass ever in your cl65? 
should have let a few more folks in front of you!!!

I've been lazy and I've still not gotten around to installing the ZT2, boost sensor, or wideband.
Max boost was 32.2, but I suppose that was without any deduction for atmospheric pressure. That seems low to me.

The 32.2 is without a deduction for atmospheric pressure, as stated. That's why I said it seemed low.
32.2 - 14.7 = 17.5 PSI
This couldn't be accurate., as it wouldn't trap 120 with only 17.5psi. I'll be installing all the datalogging bells and whistles soon to accurately datalog the beast. I just haven't gotten around to it.

Thanks. Yes, 89K for a few another week or so and I'll be at 90K. I'm sure the DA wasn't doing you any favors though when you ran. I've heard occasionally a 1K DA happens in Vegas, but it's few and far between.

Some tunes are more aggressive than others but I'd say 11.1x-11.2x +/- 125mph. I ran a few 11.1x with similar 60 ft times launching around 1200 RPMs. If you are willing to launch closer to 2500 RPMs you may see something closer to high 10s or 11.0x. Either way still pretty impressive for a stocker.
