    Never put it on a dyno, but we estimate the car at around 480-500 hp on the motor.

    What kind of tranny do you have to hold almost 500 horses? Is that at the crank or at the wheels?

    Thats at the crank, which would put it around 400 RWHP. The car has a 4L60E transmission with a 3000 RPM stall.
