regardless of what the dyno says . it still runs faster and harder than you should ever drive it. doesnt it??

 

What a contribution to our discussion. Looking at it like that, I would have kept my original 450 Honda.

 

Yes, there are many factors to ake into account, but I stand by my earlier statement. I have a buddy with an 06 Ultra. He's running a 95 inch motor with Rhinehart true duals, SE 256 cams, SERT, and SE A/C. My 01 Ultra is 88 inches with V&H Pro Pipe, S&S 510G cams, PCIII, and SE A/C. I can whip him any time on my bike, and this guy knows how to ride. From a stop or at a roll, he can't keep up. He went and bought a Thunderheader and had his bike retuned for the new pipe, and he whips on me now. The pipe was the only change and he gained 10hp and 12lbft of torque.
