There could be a substantial amount of difference not to mention the effect of the rotors freewheeling. But I have a baseline run on mine with just the muffler and airfilter change so we値l be able to calculate the difference pretty easily and it will be good info to have. Some have promised to dyno before and after the SC install but none have been able to.

My own kit should be here in the next week or so and I値l be able to lay the runs on top of each other to get a true comparison when I dyno mine.
