Drag Strip Time
I have a couple questions.
What times do a stock 2011 CTS-V automatic coupe run?
What does a CTS-V coupe weigh?
What rear wheel Horse Power from a stock CTS-V ?
Thanks for any help,Larry

I think the rwhp you quoted is a little high. For automatic cars they are more in the 440-450 sae on a dynojet. Mine was 445.
As for times, on a good air day, on a well prepped track, they CAN run as low as high, high 11's, but low 12's is more the norm.
The coupe weighs about 35 pounds less than the sedan, with similar options.

Don't have an answer for you, but I can point you in the right direction. I would give the "Cadillac Forums" a try, the have a lot of info on V2's, especially regarding dyno numbers and V2 specific upgrades and shop's.
LS1 Tech is kind of a more DIY tech site and most V2 owners generally are not as "hands on" if you will.

Yes, definitely a V1 section more than a V2.
If you are going to the track, remember to do the following:
1. Get the rear tire pressure down to about 24 to 27 PSI (depending on day)
2. Launch with the suspension in touring mode (softer)
3. Sport mode on the transmission - do not use the paddles
4. Stage shallow and leave when the last yellow comes on (good for .0xx R/T)
5. Squeeze into the gas pedal, do not stomp
6. Use traction control on the first few feet and once you feel it hook, bump the traction control once to disable - better 60 foot times
As a note, the bypass throttle assembly on many of these cars is set up so that boost in and boost out is a bit smoother but does leak some peak boost. This is more of a setting on the auto cars and why they dyno so much less. 3 minutes and a 10mm socket takes care of that. Do it before the track or you may be disappointed with ET and trap speed. I will post up a link to a video to adjust a bit later when I get a chance.

An 11.67 E.T.totally stock (except for cai) ?!!
Noticed some guy on the 2009 CTS-V (Performance mods) forum went an 11.67 E.T. totally stock except for a cai and on street tires!
What's up with that?
Are you sure about, " on a good day, on a well prepped track, they CAN run as low as high, high 11's but low 12's is more the norm." ?

You may be right about some CAI'S adding horsepower (which of course is what they are supposed to do.)
However, this guy's CAI apparently added a meager 8 RWHP over stock !
Surely an 8 rwhp gain over stock can't account for the difference between a bone stock best of an 11.99 versus an 11.67 with just the addition of a CAI ?

Noticed you list having a 2010 V with a few goodies one of which is a different mid pipe.
As a comparison how does your V's 1/4 E.T. on street tires compare with this guy's 11.67 on street tires ?

Apparently the street tire used was a stock size 285/35/19 Bridgestone RE11 which is not a drag radial I believe.
I know you said maybe he's really good but with you listing your CTS-V as making 534 rwhp and 557 rwtq as a point of reference I'd be interested in your V's 1/4 time on street tires or drag radials.

I run at high altitude, typical DA's are always over 6,000 feet, so we run almost a full second slower than what most folks near sea level run. That being said mine ran a best of 12.8x at 112 bone stock. Now, on DR's I've run a best of 11.8x at 119.5. On factory PS2's I've run a best of 12.3 at 119. For a 4,200 pound 4 door sedan she moves out pretty good.

RE11's are super sticky, street legal road race tires. That makes sense.

Based on your info and despite somebody's comment that maybe he's really good I can't understand why there doesn't appear to be another V with only minor mods like a CAI out there that has even run an 11.7 let alone an 11.67 while on street tires.

As for cai picking up 8 being normal, I picked up 30 with a new era and tune and just 15 without the tune over a lpe elbow and modified box.
I'm not doubting the accomplishment, just saying that on a dyno graph, it was probably more than 8 in other areas than peak power.

My car won't get down the track on street tires. It's usually 12.3@124. On drag radials it runs 10.7-10.8.

I dare say if you're running 10.7 - 10.8 your few goodies are also some serious well chosen goodies.
Based on input from you and others I'm beginning to think the guy whose V with CAI who ran the 11.67 on street tires is somewhat unique.

not saying its not possible, but I think theres more to it than just a CAI. he could have a handheld tuner also.
my car the only thing you see is the CAI and if you looks close, you might see the upper pulley, other than that it looks and sounds stock. if you go to the 10 sec section, you can see my youtube passes.
