"With the Pirelli winter tires on the rear, on a chilly day and on rather porous asphalt, the launch control worked best at lower rpm. At 3000 rpm, the engine seemed to bog a bit; and at 4000, there was a little too much wheelspin.  At 3500 rpm, it was just right. Hit the launch-control button (to the left of the steering wheel, with the adjustable damper control), floor the accelerator, and dump the clutch—the Shelby does the rest.

Before you ask, yes, Martindale has tried it with slicks in back, and, yes, it jumps off the line like John Force heading to the free buffet. Surprisingly, though, Martindale says that, properly heated by a good burnout, the stock Goodyears nearly match the slicks’ launch traction."
