Remember when Hennessey said they were bringing the Focus RS400 with respectively 400hp ? Apparently they made the attempt and came up with 326hp and 382lb-ft of torque in this clip of the dyno pull including chart at the end. To make matters worse, they've managed to disconnect the rear wheels in order to minimize drivetrain loss.

Through the access port - you can turn on Dyno mode, which removes the power to the rear wheels, I would imagine - if the rear wheels were powered, it would be about a 5% difference, from the front.. I don't imagine much of a difference.. So, in this case, 326FWHP, would probably yield 310-315 AWHP..

Aren't there 4-wheel dynos "out there?" Several AWD hot models that are often "tuned." STi comes to mind, and COBB has TONS of aftermarket parts for it.
