Actually, that graph is from a chassis (rear wheel output) dyno.  Look at the legend on the right hand side of the graph.

The graph's Harley includes in their catalogs, regular and SE, are rear wheel output.  I've noticed over the years that the results they publish are similar to results from independent sources, so at least in these instances they seem to be providing straight info.

Gotcha.  Thanks

I put together a 2009 Street Glide with the Harley Stage IV. The bike now has 5K miles. Very Streetable. Dyno runs show 110hp/ 106tq- rear wheel output. The only thing the kit is lacking are the automatic decompression valves and harness'. No significant sacrifice to mileage. Ran 13.2 @ 102MPH in the 1/4. I absolutely love the kit (especially when it was purchased on a dealers 20% off day) The bike runs stock up to about 3000rpm then as it comes up on the cam it flutters for an instant then HANG ON. The kit is definitely top end but nothing lost down low. For the money I don't see how this kit could be beat. The shock value of watching a bagger bring the front end 1' off of the ground at 25mph and carrying it is priceless.

Personally I wouldn't go 10.5-1 with todays gas (if you can call it that).

Not bad for a bagger I suppose.  My FXR4 with a Stage IV still just 80ci EVO (+ a couple tweeks, 2into1 V&H and Mikuni) ran a best of 11.94 @ 110.  Probably could have done a little better with additional tweaking as I was barely into 4th gear.  Rev limiter set at 6800 it would run 105 in third and bury the speedo in 4th gear with the original gearing.
