1/4 mile.

Someone claimed they ran a 12.80 in the 1/4 mile I find that hard to believe I own the same car a 2012 5.0 R-Spec and I'm a very experienced racer and have raced numerous cars and have the Trophies to prove it my best time is 13.51 at 103mph and if the 12.80 run is legitimate I want to know how in the world you got it to turn thst time there isn't a tune yet as far as I know to unlock the potential of the 429 HP on the 5.0 R-Spec.

Not correct. The tune does not add a ton of power, only about 15 20 WHP, but there is also a TCU module that raises the redline and turns it into a true sport shift tranny. I would not know how much it would shave off the 1/4 mile time since I never went with it. Maybe someone else would know, but it should shave off some time.

The best dragy verified 1/4 mile time I've gotten out of my rspec is 12.66 @112.5 mph. 12.8 should be the standard time for a clean R-spec with a good launch and low DA.

I've done 13.5 @ 107 on the highway at 45° F with cold 640 TW tires. I can't see any reason these cars can't run 12.999 or better on a prepped track with better tires.

Slap some mickey Thompsons in the rear you will see 12s bone stock.

I did a 13.6 here in Vegas , we have high altitude with heavy 20x11 in the rear and a not so good 60ft and no launch just go at green . I wasn't mad because my buddy's ISF ran a best 13.8 and some coyotes and srts bearly break 13s .
