Eagle Mountain, Utah | Justr came back from AVR last week, and here is the Dyno chart with my 2010 Black Vision with ABS. Has Lloydz's cam, VFC III, Thunder Sticks exhaust, Lloydz's plate and Victory performance air filter. See what you thinks?

New Bohemia, VA | I need one of them, that's the next goal, hopefully by 100k. I could use a few more ponies under the...uh...console. Sweet ut. |

Gettysburg, 2008 Tour Premium | I like the graph. The pipes fill in the mids real nice, the shallow dip that the S1L1 often have is missing, replaced by a big bump in torque. Is it possible to feel the sharp rise in power around 2,500 with part throttle? |

LaPorte,Tx. | It is interesting to compare my S1L1 to the Thundersticks. Our bikes are the same except his is a '10 and mine is a '08. Mine was run a hour or two before ut's. The S1L1 mufflers make more power and torque off idle up to 2500, the Sticks make more power & torque up the rpm range to 5000 rpm, then they are about even again in power and torque. Torque on the S1L1 flatens out at 5000, but hp continues to rise. The Sticks look likes the opposite, torque is risiing at the limiter, but hp looks like it is running flat. For mid range power looks like the Sticks have a major edge, at 3700 rpm S1L1 hp is 72 & torque is 103. Sticks @ 3700 rpm hp is 80 & torque at a whopping 114. Plus then sound cool.  |

| Great figures and a nice curve
I would like to see it compared to a regular Vision. |

It,s a bike to bike thing. I have charts with S1L1 that make bigger numbers, and ones that make smaller numbers. All done on the same climate controlled dyno |

Georgia, west of Atlanta | One thing stated before is impossible. If torque is rising at the limiter (5500 rpm) HP would have to be rising also. It's a simple mathimatical equation. HP= TQ x rpm / 5252. AND converesly TQ= HP x 5252/ rpm. Even if torque was just staying constant from say 5200 to 5500 rpm HP would be rising, not much but rising........EXAMPLE: if the bike was making 100 ft lbs @ 5200 rpm that would equal 99HP, if it maitained 100 ft lbs @ 5500 that would equal 104.7 HP.
Now about nearly equal free flowing slip on exhaust, like Kevin said it's a bike thing, all intake & exhaust ports are not cast to blue print specs nor are the valve seats finished exactly equal.........
