It comes with a roots style Eaton M112 from the factory. If you put full boltons, port the SC and tune it within an anch of it's life you MIGHT get to 550 RWHP. However- if you bolt on a twin screw KB or Whipple you ROUTINELY see RWHP #'s 600-800 depending on supporting mods and size of blower. The proof really is in the numbers- you can believe them or not believe them- your choice.
Manufacturers go with the HEaton because it's FAR cheaper to mass produce. You would add 3-5k to the price if you added a twin screw. Most manufacturers shy away from that kind of hike for fear of losing customers.
