No speedstar here, have the 108 with head work, cams etc (nope, didn't push the NOS button). My wife has a stocker and she's packing 100 lbs less than me and it's not even close.
I actually got beat by a Harley a couple of years ago. The year after I humiliated him two up on his bored, ported hotrod 96" Dyna then he tossed out the stock motor and got some 120" or something S&S and built it for 4 months just to beat a warrior and did (by about 4 lengths out to 120 mph or so). I still haven't seen him since I added NOS and dropped 30 lbs. When my bike was stock, there were all kinds of hotrod harleys that surprised me
