How much kilowatts would the Stroker Kit to suit Holden VN - VR V6 put out?

We offer three stages in our Stroker kits. Stage 1, 2 and 3. In regards to power figures other influencing factors would be whether or not the car is manual or auto, cam specs how hard the car is revved, dyno used, etc. As for very rough power figures could be anywhere from 20 to over 30 rwkw mark.
