Hi guys first time posting on here I have a 2014 Street bob 103 have had a stage 1 since new and am bored of it. I have been looking at both screaming eagle and s&s for the kits 110,117 and 124 just wanting to know if ppl on here have done any of these,  what prices am I looking at, power figures and any other info would be helpful cheers! 

There are multiple ways to go depending on your budget.
My choice would be S&S 110 kit, Cams, headwork and a real tune.
Likely to be around the $4-5k mark.

If you have lots of cash, an S&S crate motor for some big, dumb power, or worked over for serious power ~ $10-12k.

Taking your 103 out to 107 or 110 is a change to your cylinders and pistons. Going bigger than that requires splitting the engine case. So going to 110 is cheaper and easier. 

what's your budget. A high comp 107/110 is pretty tough thing to beat.

you are talking cubic dollars when you go 124 S&S but it's one hell of an engine.

Sweet boys cheers yer I’d rather have too much then not enough can’t seem to find any hp charts or ne thing for them was hoping some one on here might have some power charts thanks for the advice! 

And for budget probably 10k would be the most keen to spend

That's a healthy budget. Will get you a T124 installed. 

Why not just turbo the 103?  Properly done it would waste a 124 engine any day of the week!

Yer well that’s what I was hoping 10 would cover probably switch to chain and all that just want to get bit of an idea, ride this summer then next yr start ripping it down and get into it cheers for the help boys appreciate it! 

think I seen one from west side customs with a 131” turbo thing is mental! Be fun that’s guaranteed, like said cheers for all the input given me abit of an idea on where I will b and what can do for price-power any way hopefully start of next yr can get it rolling throw so progress shots up! 

speak to Darkside customs in Sydney .. they have a procharger kit for 11k installed and tuned.. numbers around the 120-130 mark...

I just purchased a 120r donk on the cheap but I would be looking at the same numbers as those above....

go charger be different.. I might even change my mind and go charger yet..
