I got it dyno'd at Straightline Performance in Forest Lake, MN. 61.51 at the wheels makes sense, because that estimates at 86hp, which is 4hp over stock with a slip on. Maybe my results are more accurate.
Its not always a measure of accuracy as much as each dyno just reads or measures differently. So you need to dyno first, then do mods and go back to exact same dyno to get accurate gains.
Not a big deal, but just don't get frustrated without taking into consideration the Dyno variable.
I think its always been known most ALL bikes gain some HP with the air box mods.....problem is, most of us want a water tight intake, and that makes it tough unless you want 4-5 snorkel risers sticking out of the fenders....!!
All the major engine builders on here all said they played with the stock air box and intake and the stock set up made the most HP every time. I'm not doubting you in any way, i'm just hoping they chime in and shed their input on this also! Thanks for sharing!
I still have my snorkels from the previous 'gade, never finished installing 'em. But don't know if I will ever go in water than deep. I got water on my belt, only reason wanted snorks in the first place. I don't see how an engine couldn't gain from more air flow, and get lil more out of it with an exhaust/controller...
