I bet it's really hard to drive at it's limits. my ls6 is 370whp and WOT at peak power it's a handful but the flat torque curve makes it a little more predictable. I can't imagine all that power kicking in all at once. Somebodies going to die trying to get a quarter mile time. I can't imagine it on the track. Did you notice he hit 8k rpm?
