Swapping Wood TW222 cams for Andrews 57

That dyno graph looks nice. The hp and tq lines intersect at 5300 RPM's, still at 100 each the bike falls right back to the RPM area of increasing torque when you shift to the next gear as the hp continues to climb. That's what I'm looking for! Thanks!
I feel like I have to watch the tach too close with the TW222 cams, if you rev past 4K and then you shift you are right back where torque starts dropping off with very little revs left to go before you need to shift again. You never get a chance to wind the bike out with the 222's, you have to shift-shift-shift-shift to stay in the peak hp/tq band. I think the 222's are for heavy touring bikes, riding 2 up and loaded down. Now if you want to pop wheelies and burn out from a dead stop and smoke the tires till 2nd gear then the 222's are the way to go. I think with 2 identical bikes with the difference is these cams the bike with the 222' will jump out ahead but the bike with the 57's will run it down and you won't have to worry about shifting so quickly. JMHO. I think the only trade off with the 57's is the fact that when you need to pass in a hurry you may have to down shift once.

Every dyno chart crosses at 5250. Even for cars. It's a math calculation thing. A dyno ONLY measures the power(hp) output of the engine/drivetrain (the acceleration of the roller(s)), and extrapolates the torque based on it.

I have the 57H cams in my SG and couldn't be happier. Even two up I have plenty of power to pass in 6th gear. Cruising at 2000 RPM is nice and smooth as well. A buddy of mine has Woods 555 in his SG and we are pretty much dead even in 5th gear roll-ons and stoplight drags.

I have the 57's and there a great cam for the 10.1 comp. that the Limited offers. The more you twist the throttle the harder she pulls. I'm running the Jackpot 2-1-2 ceramic coated pipe with RC 4" mufflers with a little more work on the baffles and tuned with a PowerVision. Bikes runs awesome period. Here's the dyno sheet if that means anything to you guys.

I have but didnt really look too much into it. Do you have more info of things like parts, part numbers, etc??

I just did some research and came back with the baker 30t-07 pulley and the BDL-SPC-139-1 belt. Can get both for about $300...same as a cam swap basically. I can do cam swap myself (already did it with the 777) and re-program the PC-V....or I can do the 30T and have to pay someone to do it because I dont have the proper facilities. Hmm....decisions decisions.....
