DYNO Numbers for Baggers???

I just had my 08 Road King Classic dyno tuned and thought I'd share the numbers.

The build is:
103" Big Bore
Flat Top Pistons
255 CAMS
SE Heavy Breather
V&H Dresser True Duals with Rinehart Mufflers
Screamin Eagle Pro Race Tuner

The corrected, rear wheel dyno values are:
HP: 85.97
TQ: 106.8

I was dissapointed by the HP value, but very pleased with the Torque value. What do you guys think???


My first impressions riding the bike;Pulls away noticably stronger through low and mid range revsPopping on decel has stoppedBetter engine / exhaust note over 4K RPM (used to develop a "tinny" sounding rattle)Starts like it did when it was stock. i.e. within first 1/2 second of starter. After the 103 big bore kit was fitted the engine needed one or two seconds to kickOverall the motor seems to have a stronger "beat" across all RPMs (but this is a very subjective)Overall I am very pleased with the improvement to the feel and ride of the bike and feel the dyno was a good investment to maximize the value of my engine upgrades.

Any thoughts on the lower than expected HP number?
 
Out of interest has anyone ever dyno'd a totally stock 08-11 Tourer?

I'm assuming the numbers HD publish in the bike specs are rubbish. (I know the gas milage figures always give me a good chuckle)
 
Had my 07 sg dyno'd today. American cust. slip ons stage 1 breather pc III
before #'s 63.85 max power 77.5 torque. After 71.1 hp 85.05 torque.
Didn't seem to rattle as bad in 6th gear @ 2000 rpm Don't know if this is considered good results or not?

Kroozeabout. would post the actual chart but I don't know how, me and computers.
 
Stage II done last year with Kirkers,SE tuner, etc.. - dont have the numbers from that work but just got the bike back from builder who did the heads ( does that mean a stage III ? ) - Base map, bike ran great and sounded great . Dyno tuned and im at 105HP and 115 TQ - He said prior to the tune I was at 97hp and 99TQ but the bike seemed a little faster then.. weird? i'm gonna talk to the builder and see what that's all about but as it is now.

105 HP
115 Tourqe
 
C-Man: Most bikes come in around 63-68 HP, 80-86 TQ, sometimes you get the odd one that really shines and comes in a little higher these numbers. My 08 Street Glide was on the lower end at 63 HP/80 TQ. After cams, intake/filter, slip-ons: 83 HP/95 TQ.
This was on a 96" motor no head work, and using the SE Super Tuner. Hope this helps...
 
I just had Andrews 50H cams installed on my 2008 SG I already had DD Fat Cat, S&S Single Bore intake and a Power Cammander. Wow what a difference I love it, the engine pulls hard sounds great, it seems so much smoother at higher revs. HP 94.62 Torque 96.86
 
2006 Road King Classic. 88 c.i. SE heavy breather. V&H dresser duals. Rinehart slip-ons. PCIII USB with fuel moto map. 81.03 hp/87.73 tq.
