Hay guys. I like to see a m8 107 with Rinehart header, 4" mufflers rhinehart/ Arlene Ness c/I fp3 autotuned. With s&S 475 cam on a ultra limited. Real numbers. I'm getting ready to install the 475 gear drive cam this weekend and well there is not one dune tuner less then a 5 hour ride from me.
Not your exact setup but this should give you some "ballpark" numbers.
2020 Road Glide Special: FM 128 big bore kit 10.75:1 comp, Wood WM8-22X cam (retarded 4 degrees), stock heads & valve springs, SE 64mm TB w/Ward manifold, FM AC/DC air cleaner, AIM SDR clutch, Jackpot 2/1/2 head pipe & Hi Roller mufflers

Wondering what the stage 4 kit costs and what kind of reliability issues or concerns are there with it ? I only ride about 2000 miles a season, but would love to turn my 2018 Fat Boy 114 into a fire breathing monster

Gonna take more than a stage 4 to put you into that category with a Harley.

i realize stock heads are ok for use with the Woods 22X cam, but have you built a big bore M8 with the 22X cam but with upgraded heads, 64 TB, injectors and a solid 2/1/2? I suppose the 408 cam more fully utilizes the performance ability of the upgraded headwork, but I’m curious if the 22X would give all the low end benefits but gain more hp above 4500 rpms with the upgraded headwork. Thoughts?

Might be what my new 19 SGS needs
Did the FM 128 Woods WM408 level A heads 64mm TB build on my Fat Bob with fantastic results, but this looks just about perfect for what I want for the Street Glide. More down low and a really broad torque curve. Wouldn't have the crazy top end charge of the 408 cam, but that is not what I want for this bike.
