Hi there,
I have a 2011 electra glide ultra classic. Previously owner did a heavy modifications on it. among the mods: stainless hi output 2-into-1 vance & hines for competition, Arlen Ness derby sucker air filter, thundermax 309-362 performance ECM, feuling race series camchest, screaming eagle pro hi flow injector kit, screaming eagle variable pressure clutch with heavy duty clutch spring. the original 103 engine had incorporated: screaming eagle pro stage IV kit, screaming eagle pro twin cam 110+ cylinder heads, screaming eagle pro twin cam forged 10.5:1 compression piston kit for MVA (?), screaming eagle race valve spring kit, screaming eagle throttle body 58 mm hi flow. My question is: With all the screaming eagle kits installed in this engine has had upgraded it from 103 to 110+?

 

You know all the specs but don't know if it's a 110?

Congrats on your first post and welcome to the Forum

 

kind of. I know the original engine is 103. Cylinder heads kit with pro stage IV kit made the original 103 to 110?

 

The SE Stage IV kit for the 103 includes forged 10.5:1 high compression pistons and rings, SE 58mm throttle body, SE CNC ported cylinder heads, SE-259 cams, perfect-fit pushrods, top end gasket kit, and heavy duty clutch spring. It does no include larger cylinders or stroked flywheels that would increase the displacement. So unless there were more modifications, like cylinders and flywheels, it's likely still a 103.

But nothing wrong with that setup. The 110's tend to run a little hotter than the 103 anyway.

 

Thanks bro. Crystal clear. The only thing that still a question mark is the screaming eagle logo at the top of the cylinders.

See the screaming eagle engraved in tne cylinder.

 

If you are referring to the highlighted Screamin Eagle text in your picture, that's on the cylinder heads that came in the kit.

Nice looking bike, hope you enjoy it.

Find a copy of the 2011 SE catalog, and you'll see everything from the SE STG4 kit that was put on that bike- still a 103, rated at 105 TQ and 110 HP.
Find a local dyno, and pay for a couple pulls to see where it is now with the current components. (the big pipe & T-Max ECM may have helped, may have hurt)

 

Ok, looking back at your initial post, you did say it was a "screaming eagle pro stage IV kit". I missed the "pro" part of that (more coffee needed), so I stand corrected that it is the 110 upgrade because the pro kits includes big bore cylinders. As shown in the link below.

thanks man. You did help a lot. I do appreciate yor time. No further doubts.

 

My 103 Stage IV with the stealth air cleaner and the V&H stainless steel Pro Pipe made 119 HP and 107 ft. lb. torque, and that was with the Screamin Eagle Pro Super Tuner. (2015 Ultra Limited)
