this from fuel moto with a pcv from H.D forum couldnt get the dyno sheet to copy over but is posted on this page on that site. i bet if they used a d&d 2-1 pipe and had a tts master tuneer i bet it wouldve been even higher, So with all things being equal as dewey said it should be! the tw-7 kicks ass over the lame 255
vs SE255 Cams test 110" CVO Road Glide
Here are some results from a cam swap we did yesterday. This bike is a 2009 CVO 110" Road Glide. For exhaust it has a non catalyst head pipe and Klock Werks mufflers, it was also equipped with a Dynojet PC-V since last year. This bike belongs to a long time Fuel Moto customer from the other side of the state that has brought us several of his bikes over the years for dyno tuning and services. He was looking for better performance, better response, as well as cooler running. While the stock SE255 cams are very good for very low end performance we were looking for improvements thru out the entire RPM range. We chose the Wood TW-7H which has a the same open/closing specs and duration as the popular TW6-6, however the TW-7H has .575 lift versus the .510 lift of the TW6-6 which will work especially well on the 110" motor, there is also a big difference in dynamic compression compared to the stock SE255 cams. The timing of the TW-7H will allow the motor to rev more freely and be less prone to detonation. We started with a full dyno evaluation just as the bike came in which was 90Hp/108Tq. Conditions were poor as we had 90+ degrees and over 40% humidity. We did the cam swap, gave it a full dyno tune and the final numbers we 110Hp/118Tq, when we finished the tune it was over 100 degrees and very humid however the results are very impressive with nealy +20Hp/10Tq gain from a cam swap. The before and after results are shown below. The improvement is excellent, with immediate response and the idle is awesome. I will try to get some video before the bike is picked up. More to come.......
