You need to carry that bike to Daytona for the Brute Horsepower Sootout in 2010. I think you have sometiming there.
 
I'm sorry but I'm gonna' have to call BS.I could see those kind of numbers if your running a Pro-Charger or Turbo,but just being natuarally aspirated I find it kinda' hard to believe.
 
Dropped the bike at HD last night.. they worked on it last night and most of today. Road it home in the rain, so didn't really get a chance to "run" the bike to see how it performed. Hopefully this rain will stop for a day this weekend :-(

So, this was the cam change (SE 255's) on a stage 1, 07 Ultra. It included a dyno tune, the dealer's dyno is a SuperFlow WinDyn (This dyno is generally 10-15% lower than measured on a DynoJet for the same bike). Because of the differences, I had them do a baseline run prior to doing the mods/tune.

The results: Gained 9 ft/lbs TQ and 9 HP over stage 1 (could probably be a little higher with different slip-ons?)

Before mod: HP = 65 @5500 rpm, TQ = 79 @ 3600 rpm (stays above 70 til 4700 rpm)
After mod: HP = 74 @ 5500 rpm, TQ = 88 @ 3200 rpm (stays above 80 til 4700 rpm)

Corrected to the DynoJet, this would be about: HP = 82 and TQ = 97 - this is a little better than I'd hoped for, especially the gains in HP. (second chart shows the HP corrected to 81.6 as it would be on a DynoJet)

I've attached the SuperFlow charts. I think it is a pretty good curve. ATR is at 13.4 until cruise which is set around 14.

07 Ultra, SE A/C, SE II Slip-ons, SERT and now SE 255 cams
