Not sure about the horse power but your cc's stay the same unless you go up in size which you now have a 1690 cc 103 cu in = 1690. What kind of cams do you have in it? I have a 08 street bob with vance and hines short shots vance and hines vo2 air cleaner andrews 50 h cams a power commander and its bored out to a 103. I am putting out about107 horsepower
