A couple days ago I installed the ghost, and went out to do some runs. Takeoff is phenomenal, of course. The front end positively leaps upward in response to the increased rear torque, and now I understand why a 1ft rollout time might be reasonable, since some of the takeoff time is used in lifting 4000lbs of car six inches before acceleration REALLY begins.
Initial dragy runs, with cold tires, 54f outside, a cold battery, and only 40% charge were ~3.58s, with a 3.37s 1ft rollout. I little disappointing I thought, but my butt-dyno certainly couldn't tell a difference between 3.58 and 3.40(below).
A day or two later, still cold tires, but 61f outside and 90% charge rate got 3.40s with a 3.16s 1ft rollout number. This is probably in accordance with the advertised specs for the Ghost, which say 3.2s. There's probably a
little more speed in there, but it'll take a hot sunny summer day to try it.
