It is not unequivocal.

there are points that make a difference.

Pistons in the hole due to new cranks
Cams with overlap that the new 255's dont have
Valve to throat values and flow as well as 1.94 vs. 2.080 valves.
5 speeds to 6 speeds and gearing changes.

Comparing apples to apples is in this case is just comparing stock to stock but not truly apples to apples.

I somewhat agree but apples to apples to me means stock to stock or $3000 to $3000 engine in upgrades with an equally competent tuner for both builds. Stock to stock the 110 will always outgun the 103. And I'd feel very confident in making the same claim that $3000 in engine/inatke/exhaust upgrades will also result in a higher performer engine with the 110 than it would with the 103.

Take your choice but in any case I can imagine the 110 will outgun the 103 every time when the comparison is "apples to apples". Of course you can always make an apples to orange comparison and find a "worked" 88 that will blow away a stock 110.

You are right Gary it does not really matter one way or the other. From Heatwave's post I gather he spent $3000.00 on his upgrade to get the dyno numbers he has posted in his profile. Really nice numbers but I have also seen numbers very close (some higher/some lower) after spending the same on a 04, 05, 06 103" which is not the same engine as the 2010 and up 103". Not trying to upset anyone or cause any problems just talking about stuff but if you wann run'em come on down. The 110 equipped engines are about 100 pounds heavier then you have the riders weight to factor in, then reaction times along with fear and pucker factor of the riders. Life is great and I am having a wonderful  time.

I agree with Gary, what difference does it make?  I could care less if your 74ci beats my 110's.  I didn't buy them to drag race, nor did I get them for bragging rights, (other than to say I have CVOs  ;) ).  I really don't care how much HP I have or TQ for that matter, as long as I enjoy riding my bike and it makes me happy....after all that's all it's really about...so who cares if a 103 is better/faster than a 110?  I sure don't.

Exactly.  And btw, we now have three pages of responses that didn't answer the man's original question at all.  He wants to know about the 2011 factory optional 103, which has absolutely nothing to do with the old CVO103, or "built" engines, or any of that other bench racing BS.  If he buys a new 2011, should he stick with the standard TC96 or should he go with the TC103?  What are the potential benefits versus potential drawbacks?  Is the bump in displacement necessarily going to result in a proportionate bump in performance? ETC.   IMHO, it all depends on if the factory installed big bore kit is a stand alone item or part of a package like the Limited, and what kind of pricing will be involved.  If the price is less than what you would have to pay a dealer to install the same 103 big bore kit, I'd go for it.  If you have to buy a bunch of other options that you don't really want, like with a Limited package for an extra $2000-$3000, I'd pass and just spend the money on the upgrades I really want.  Reliability shouldn't be any different than with the TC96, and the increase in performance will be mild.

Anyone who actually owns a 2010 LTD with the factory 103 might want to jump in with their observations and opinions.  That would be much more helpful to Aero8 than having us discuss the old CVO103, or whether a built 103 can thrash a stock 110, or whether any Harley can keep up with a 900cc Ducati or any of about 50 different metric bikes, et al.  ;)

It seems (still a rumour?) that in 2011 MOCO will produce some Touring models( FLHR, FLHRC, etc.) with a 103 Twin Cam.

What is known about reliability and performance of this engine?
Is the performance close to the 110 or is there still a big difference?
Is the 103 a big step forward in comparison to the 96?
Is it recommended to buy anyway the 103 engine, because it is based or similar to the Police engines?

You're right Chip, it is a little scary when I become the voice of reason.  Remind me to cut it out if it happens again. ;)

And you're also right about the tilt.  It should show up in my profile starting with this post.

Really doesn't matter. Just fodder for a "mine is bigger than your's" thread which usually have a high entertainment factor to them. But the reality is they're all great so long as they are over 2 wheels and the rider has plenty of time to wear down tire rubber.

FWIW I spent a whole heck of alot more than $3000 on upgrading my 2010 SEUC.

FWIW I would favor the 103 for cost per mile. A lot more reliable motor and able to top 10K easy without motor work.
