The manufacturer reports the 5.5L as having 395kw at the flywheel and a 0-100km/h time of 4.3s.
As delivered with the addition of custom downpipes we performed a base Dyno run of 277kw at the wheels.
After custom tuning power rose to a very impressive 426kw at the wheels. Thats a 149kw gain at the wheels.
