2013 Laramie CC 4x4 8spd...1/4 mile runs
 
Well, since my 2014 with 3.92 gears will be hear in a week or so, figured I'd take my 2013 with 3.55 gears to the strip to see what it would do before turning it over for my 2014.

Here's the details
2013 Laramie Crew Cab 4x4
(so yes, it's basically loaded, other than a few options, which = heavy. The Longhorn may be 100 lbs more but that's about it)
8 speed auto transmission
3.55 axle ratio (no longer available on Laramie Hemi's for 2014)

1740 miles on odometer
completely stock, not a single modification, no weight removed.
3-4 gallons of gas in tank
89 Octane used

60-63 degrees at time of runs
DA ranged from 55 feet to 220 feet above sea level.

Interestingly, I did runs with the power mirrors folded in and the tailgate in the down position, but not one of those 3 runs had the best times.
Both of my best time (best in 4WD Auto mode and best in 2WD auto mode) came when the mirrors were out and the tailgate was up.

I also did two runs where I launched in 4WD Auto mode and switched to 2WD mode in 2nd or 3rd gear and neither resulted in best times, truck seems to pull power for a split second while it switches from 4WD to 2WD. Times were competitive to other runs, but didn't result in best times.

I only turned off Traction Control and let the truck shift itself.

At "No Problem Raceway" between Baton Rouge and New Orleans

2WD Details: -----Time Slip: -------- VBox Results during runs:
60' --------------- 2.129
1/8th ------------ 9.496 @ 73.92 ------ 9.5 @ 75.3
1000' ------------ 12.365
1/4 -------------- 14.798 @ 92.00 ----- 14.8 @ 92.9

VBox 0-60 was 6.4 seconds



4WD Details: ----Time Slip: -------VBox Results during run:
60' -------------- 2.166
1/8th ----------- 9.527 @ 73.87 ------ 9.5 @ 74.9
1000' ----------- 12.413
1/4 ------------- 14.874 @ 90.91 ----- 14.9 @ 91.3

VBox 0-60 was 6.5 secs



Once I get my 2014 with the 3.92 gears (all else is the same, I ordered the 2014 with the same options as my 2013) I'll return to the strip and see
what the differences of the 3.92 gears are.

I also have times for street rolling runs and will do the same on the same road in the same place with the 3.92 truck once it's broke in. And I'll do them in the same low 60's degree temps too.

Have you weighed your truck? I was shocked when I weighed my 05 at ETown, NJ. 05 QC 4X4 hemi SLT weighed 5985 lbs with me in it =250 lbs. Anyway, I ran an eighth mile up here in Maine a couple weeks ago. 60' = 2.158 330' = 6.228 1/8 mile ET= 9.660 speed 72.13mph. I have 3:92 gears and the old style non mds 345 hp hemi with a cam and shorty headers. BTW I was beaten by a Mustang GT by .792 sec. However at 60' we were dead even.

I can't wait for your 2014 times!

I haven't weighed it.
But based on what the manufacturer has stated and what Car and Driver got for a Laramie Longhorn (which was about 5950 lbs), I'd say my truck is
5800-5850 lbs.
The Longhorn is about 100 or so lbs more.
The Laramie is nearly loaded as is, but I don't have a few of the heavier options either:
1. Sunroof (usually adds 40-60 lbs)
2. Air Suspension (have no idea what that weighs but I'd guess it's heavier than the standard suspension)
3. Locking bed toolbox things. I've looked at one that had them and I'd have to imagine that it adds 40-60 lbs to the weight of the truck too.

Neither can I
The trick is going to be getting a run at the track when the temps (and DA) are about the same.

Will keep you all posted

Me and my buddys go run at no problem pretty often. My 2012 ram 4x4 with 3.55s bone stock ran a 15.318 @92.69 in a -50s da back when i first got it. Havent had a chance to get out there since i added some modds

Sweet, not bad.

I figure if I had some negative DA's I could of gotten high 14.6's at close to 93 from my heavy Laramie.
But when I finally ran it in 2WD mode the DA's were in the 200-225 feet above sea level range.

Send me a PM if you plan to go in the near future.
If I'm able too I'll go.
Was just told my 2014 will be in probably by the end of next week.
Then it'll be a month or two for some break in before I go to compare.
But by then temps will be quite a bit lower than the low to mid 60's I had last week for equal comparison purposes.
But if I can get 14.6's at 92+ mph out of the 2014 with the 3.92's instead of 3.55's I'll be happy with that in a big heavy tank of a truck like the CC Laramie 4x4

The 8 speed auto in the newer 2013's and 2014's, combined with the slightly more power have my nearly fully loaded tank of a Laramie CC 4x4 running similar times as the 2009-2012 Express Regular Cab short bed with the 6 speed auto, and that truck is like 800 lbs lighter than the 13/14 Laramie CC 4x4

The 8 speed auto is a gem.
