I was wondering why you can't bore a 88 cubic incher to like a 110 or 112 like the screamin eagle dyna??

103's the biggest displacement???

I don't get it,,, someone let me know.

And anyone notice any difference between the 2?

your buddy,

its due to the thickness of the cylynder wall. You can only bore it out so much before it is too thin. For motors to go to the 103" or bigger, not only is the bore size increased, but the stroke as well.
If you have an '07 motor (which it looks like you don't), the CI increase was acheived, not be increasing the bore, but by increasing the stroke.
The advantage '07 owners have to this is that they can increase the bore to go to 103" or 110" without having to crack the case open to replace the flywheel (i.e. its suddenly a cheaper upgrade)

as far as the differences, I don't know. I can tell you the difference between a stock 96" and stock 88" are minimal

 

110" would require case boring on a 96".
You can take a 96" to 107" with an aftermarket kit (Rev Perf) without case boring.

 

http://www.zippersperformance.com/ Check these guys out...You can get your 88" bumped to 120" and you'll be getting over 120 HP...That should buy you some braggin rights

 

You can take a 07 96" to a 110 with no case boring! se makes a 110 kit and its bolt on

 

Uh, no again. Check page 97 of the 07 Accessories catalog.

Read where it talks about fitment......

 

107 cubes is definitely as big as ya can go with standard cases. Any bigger, 110,113,114,120,etc,etc, and ya cases are com'n apart, no doubt. Checked ya link and it says the same thing dude. If ya need confirmation, best to check the SE catalog. Have ridden a 107 Dyna with GMR heads and Andrews cams, 128hp-130ftlbs. Awesome is the only word.
All the best.

 

Screaming Eagle catalog has 113 inch kit

 

ok so the stage one says nothing of case boring but the stage 2 says you need case boring? why is that
