Yesterday I got my 2020 M8 114 back from the dealer. I do not have a Dino chart to share but I went on 30 mile ride today ( unusual 65 degree March day). First of all I am not a mechanic and and only share my impressions based on riding experience on many different bikes since 1983.
I have done (or had dealer do) multiple modifications on a variety of bikes over the years. I can say without a doubt the 447 cam upgrade has been the most noticeable power increase I have experienced. I also did screaming eagle intake and tuner.
My last bike (Indian Springfield) , I did pipes, intake and tuner. I noticed a slight increase, I had to concentrate to notice. This upgrade on my TriGlide was quite obvious when I hit around 3000 rpms. Wow! Like I said I do not have dYna charts but this power increase was very obvious.
I climbed a steep hill with my wife on the back in 5th gear and prob could have gone to 6th. The torque feels like it just wants to pull. I will later post how it impacts my gas mileage. I also put a HD cooling fan with an auto thermostat to try and offset the potential heat increase from the cam. Talking with Kevin from DK Customs is making me consider an oil cooler ( prob after warranty). I will be doing some of DK custom mods after warranty as well. I really enjoy this trike and now I just want to twist that throttle. Be Safe BK
