The manufacturer horsepower rating not known. Anyway,most of the time, different manufacturers use different bench marks, not advisable to follow them to compare between brands and makes.
This is rated 7 stars over the older RB X12 of 6 stars... some substaintial gain in horse power over there!
Guess it's because of the multi port thingy... more efficient expulsion of exhaust and more effective intake of fuel...
