Nobody has posted actual JB4 time figures with a dragy aside from one guy on reddit. The difference in speed in his pulls was around 20%, which is substantial, but it seems like he didn't really know how to drive the car and test it if I'm being honest, the perception I've gotten is that it's slightly more than that in the real world.
Well although mine is a I4 I have gotten 0-60 3.2 seconds and 11.3 @ 122mph. Street tires on street DA of 1500' . Prep track, lowered tire pressures, warm tires I believe 10.9 may be possible . Draggy Pro measured
