Depends on what else you do but for the twin cam the rule of thumb is, and this means VERY approximately, 1" = 1 HP. Not exact but close.

I don't know about numbers but I did the 103 stage 2 kit with the cams on my 08 Rocker C and the bike runs great and pulls hard.&nbsp\\;I have ridden 96in bikes and you can def feel the difference.&nbsp\\; When I'm out with the boys we don't race or anything but we do&nbsp\\;hammer it pretty often and I walk away from them every time.&nbsp\\; I highly recommend doing the kit.&nbsp\\; Dollar for dollar its well worth it.

Not sure why so many people call them "stealers"....their labor rates, at least in my area, are dead on what independents and car dealers charge.&nbsp\\; Everything they have done to my bike has been perfect, and my experience with 4 different service departments has been absolutely outstanding.&nbsp\\; very professional folks.
&nbsp\\;
anyway.....I got the $1,199 Stage 2 Big Bore 103ci kit, and also got the $995 SE Cylinder heads......I was getting 79hp and 89.2 TQ with that set up, using a standard HD diag. download.&nbsp\\; labor to install everything was 8 hours..
&nbsp\\;
just TODAY, I had the V/H BR 2-into-1's put on along with a Power Commander III tuner.......I will get it on the dyno at the dealer's other location this coming week.&nbsp\\; wow, what a difference from a SOTP point of view.&nbsp\\; pulling power like I've never experienced on the bike.&nbsp\\; I'm not going to take a V-ROD at a stop light or anything, but this thing really hauls the mail.
&nbsp\\;
the thing about getting the stage 2 done....you have to get a 2-into-1 exhaust and a race tune in order to get the most out of it, or that's what i found in all of the long research I did on this.&nbsp\\; The whole process gets expensive which is why I broke it up into two pieces:
&nbsp\\;
got the Stage 2 and cylinder heads done upon delivery of the bike as that was required to maintain warranty.&nbsp\\; then, got the exhaust and tuner today....another $1400....
&nbsp\\;
It's not cheap, but wow, it really wakes the bike up.....I plan on keeping my FXSTC forever, so I don't mind putting good money into it......

Unless you live in a state that is DEMANDING EPA regulations be met, I'd suggest going with an after-market 103" or 107" kit.....GMR, Head-Quarters, Hillside Cycles...they all make nice set-ups.&nbsp\\; You can find more info about them in the Engine Modifications section.&nbsp\\; These kits are roughly the same price as a Screamin Eagle 103" Stage II set, but out perform them.&nbsp\\; They usually come with cams, jugs, pistons, heads, etc.&nbsp\\; More "bang for the buck."&nbsp\\; I only wish I'd known about these options before I did my 103".
