The people who truly know aren't going to tell you.

I believe 300hp +/- is the average of a "good" Badger motor. There may be a couple out there making well to the plus side of 300, but they're not making 340-350. Just based on my own observations, YRMV.

You know D2-legal Ecotechs have won Badger races in both of the last two seasons? The one that did it last year was for sale right here in the classifieds. Actually now that I think about it, the engine that won a race in 2016 may have been listed on here as well if you want to search back a year or so.
