92 springer 80hp;79lbs tq
11.0:1 Wiseco pistons;Crane 310 .550 lift cam;port and polished heads; S&S super e; V&H short shots.
I did have a Crane 314 .600 cam but my pinion shaft on the stock flywheels kept shearing off. I switched to a S&S flywheelThat 600 cam really made a difference. I nevered dynoed it but it felt like it had a least another 20 hp because the difference is like night in day when you hammer the throttle.

FWIW, I got my '92 FXDBD dynoed this summer to check jetting/ignition to try and improve it. Running SE heads, Mikuni HSR42, SE-11 cam, SE 10:1 pistons, stock headers, Dyna ignition (dual fire).
The result was 85/85 on the dyno- not too bad for stock lower end with 83,000 miles. I'm not sure there's much more to get from it and it's more than I'll ever need.

Your numbers sound great! I now have an S&S V107T in my bike, which at 1500 miles gave 103bhp and 102 ft/lbs. Those extra 20 bhp cost me a hell of a lot!
They are certainly not run of the mill numbers, well done!
