Not buyin it. 120 hp and torque from a 103 stg 4 out of the box.Especially with stock header and rinehart slipons Ive installed a bunch of these kits with numerous different pipes, and on every big twin model. Never broke 113hp and 109tq.
Just got the RB racing LSR 2-1 for a street glide i inst. the 103 stg 4 kit on a while back. made 113hp and 107 tq. We'll see what she does.

Hobbit ive had good results with compressor heads. What cam are you using?? You would never 120hp and 120tq from the 103 stage 4 S.E. offers, especially with the 260 cams! Its a top end hp cam.

Heavy cluch spring
After tuning with the SEST It made 113hp and 107tq with V&H power duals w/ rinehart slipons. Ive installed about 6 of these kits and this one made the best numbers. 2009 FLHX
My 103 has Rhinehart true duels, PC-3, and a K&N airfilter. I plan on SE211 cams later this year (or should I consider some other cams?). Dealership dudes say this is the best bang for the money. I don't have a couple (or more) of K's to drop on this. They say they can put them in for about $800. I think this is a pretty good deal. I'm looking to get somewhere around 100 (tq &hp). Is this off base? Thanks, Tracy

Have witnessed 119/119, SAE, 103", set at 11.0 cr, with a set of heads that pull 155 cfm @ 10" at .600" lift, with a Wood 9B/44mm cv carb/DTT ignition/Thunderheader.
Mid-120's square, SAE, with 107" (3.934" bore), Wood 9B, 55/58mm HPI Max-Flo 1.800" intake port, D&D Fatcat BB baffle. Those 2" valve heads pull 170-173" at 10", at .700" lift.
Keep an eye out for an American Iron Magazine issue(s) with a 98"er that rolls off 119 hp and 112 ft lbs, pulling though a lousey air filter.(122/144 with correct filter)
I'd be interested in seeing the dyno reports, with weather conditions, on that Squeallin' Seagull kit, that produced those numbers.

I have an 09 heritage. 103 stg iv se kit installed. I didn't like the 260 cams. I thought it felt gutless on the bottom end where I ride most. I had a set of woods 400 cams installed and then dyno tuned with a powercommanderV. I got 104hp and 118tq. The nice thing is my tq comes on at lower rpms. You can really feel the power this bike has now.
