Don't believe magazine 1/4 mile times. They are almost never run under optimal conditions and often with drivers that simply aren't that great. I haven't taken my RC F to the strip. But every car I ever owned that I took to the strip beat the advertised 1/4 mile times on my best runs.
Example: My first 2007 350z was advertised at 13.8. My personal best when stock was 13.5 on a 2.0 60' and it was a Touring edition (heavier). No other Touring edition has ever beat my time though (at least on the forums). I only went to the strip twice before I started modding it (so every trip after that was no longer stock). The very best stock times were as low as 13.0-13.1 (I believe the 13.1 time as I knew the person who ran it and he was a great driver, but I'm not so sure about the 13.0 time). That's a very big difference between advertised time vs. real world time. It's often easy to know approximately what a car is capable of running in the 1/4 mile by looking at the trap speed. A 113-115 mph trap speed certainly means a much better time than 12.8.
Edit:
Here's a video of a stock RC F beating the advertised 12.8 time:

For comprison, bone stock the best I did was 12.8 in cool weather. But I haven't figured out the electronic nanny situation after burnout at the time
i only have 11.5k miles currently. Could it be 30-40 pounds trunk weight reduction and 2 gallons gas making a huge difference, maybe. But not that big of a difference imo
also the RCF is very hard to launch for an automatic with all those nanny electronics. If it took me that long to figure out how to perfect the launch, I doubt the magazine drivers fully maximized it

to be honest, I think it's the cooler weather. I couldn't get it under 12.7 last time (with borla) no matter how many runs in 90 degrees. This time I'm running consistant .2-.3 faster on each run compared to last. Can't wait to go back in the 30-40s degree to see if I can run even faster

not yet, but I think i might try to make it out there this coming Friday, if i can manage to find nitrous (apparently there is a shortage after the airgas plant explosion) plus i already have the drag radials. we have been between 73-84 degrees friday calls for 87 high and 59 for the lows

Congrats on your times! It's exciting to see an RCF with these types of results. Curious why not Sport + instead of Sport? Also, what psi were you running on your tires?

Reading the review from motor trend for lc 500. They noted fastest time was in normal as well. Wonder if has to do with the transmission shifting harder in sport+ that detracts time but gives you that kick.

I fully understand the air density and temps...but you don't think the better times was due to the Borla? I thought the Borla added more hp and TQ...No cause and effect relationship on adding it?

yes, according to my butt dyno it does pull harder compared to stock on the street. But the 10hp increase on a 2 ton car is not going to do much on the 1/4

quick question.. im running into a problem with my rcf lol. im equipped with the TVD package not sure if it will make a difference ( although saw a post tvd is slower than basic lsd) but every time im at the track now i avoid doing burnouts because my car get stuck on 2nd gear telling me the road is too slippery cant engage 1st... i get super pissed and im about to stage at 2nd gear lol... got a 13.9 lolol, anybody run into this problem? well it sucks i run 13.000 flat with 20x10.5 work genosis 295 rears toyo 4plus 35psi, borla catback and drop in.. and i know stock gets 12.8 now even faster. i launch at 1800rpm, 60'-2.210 lol horrible. and i really want to burnout but i face that stupid problem.. i can only get back on 1st if i hit over 18mph in motion but ill past the stage by then. wind is an issue where i track. cool day tho 60 degrees. anyone have that burnout problem?? i try to turn off car wait like 5 secs or put back to park then to manual... nothing lol, this is why i miss stick lol

here is what you need to do after the your car goes into 2nd gear slip mode... drive the car straight until it unlocks and goes back to 1st. Then reverse back to starting line. Yes, you will look silly front of everyone, but thats the only way. Also I found it better to use sport mode instead of sport+
With 60 degrees, 12.4 is easily achievable
