Could you please  introduce yourself  a bit  better than that?

This FBuser  number bullshit doesnt  cut it for me.

A stock engine 2012 103 with a bolt on cam will give a noticeable bump in hp and torque. A stock harley 103 engine won’t pass 100hp no matter what cams are in it. You need Head and throttle body changes to pass 100hp. And usually bigger cams and higher compression.  A good bolt in cam will pass 100 foot pounds of torque.  222 is good for early torque as is a cr570 but the Andrew’s 48 is just as good if not better, cheaper and will also dissipate heat well with a good tune. 

Alpha Performance Engines in North Queensland (dunno if they’re far enough north to be considered fnq) are a reputable shop known for performance work. I know they’ve done a heap of stuff with m8 engines but no doubt they would’ve done a heap of twin cams too, probably done forced induction builds etc. But if you’re living in north qld, bolting on a turbo to an already hot air cooled engine, for a street bike, doesn’t make a lot of sense to me. 

If wanting straight out grunt all over, a Rocket 3 as per above post does the trick. Don’t even have to modify anything if you don’t want on
