707 HP....with the Red fob ignition key. But the black fob key down rates the engine power significantly. It's called the valet key and the one you give to your 16 year old son.
The HP to weight ratio with the red fob, must be tremendous and I understand the 1/4 mile time is in the low 10's @ over 120 mph. Think that's with drag radials.
Now that's performance.
BTW, got my info from Hot Rod magazine.
