Great job and video, for those looking to do this,,, one tip on best practice, mount the A/C backing plate before you tighten the intake bolts. The backing plate is part of the intake support and helps with proper alignment. Cheers.
Well done! Just received my 55mm screaming eagle manifold. I went stage 2 with tourqe cam and wide band sensors previously. Expecting to be pleased. Thanks again!
Will be doing my manifold too, using the S&S version ,port polished myself and heat painted it gloss back,doing it because a$20,000 dollar bike shouldnt have plastic for high heat. I have a 2019 Road King Special. Thanks for the flick.
Appreciate the measurements. I think a port matched 55mm is the way to go on a M8 stage 2. The 64mm SE manifold/TB actually has smaller cylinder port ID measurements than the 55mm due to the shark fins and thicker walls lol.
Good stuff. Yes, a throttle body, and manifold is an important addition to the “Modified Stage II”. Along with the cam plate/pump/tappets/tappet cuffs/push rods/Timken bearing/Power Vision/ and of course a killer cam. I’m running a Woods 22XE on my 2020 Fat Boy and came to your video because I decided I should have added a manifold. I’m going follow my initial instincts this time and dump a Thunder Max on my Road Glide 107 to S&S 129 build. Please don’t edit out to much because each teaches what to do as well as what not to do. Great video! ET1(SS/SW/MTS) US Navy, Ret.
Hey OTW, I believe after watching several videos you are the only one that I have seen that replaced the Manifold to head gaskets,, I myself can't understand why more people don't , that is a known area for leaks,,,good video. I didn't catch if you did or not but these things need to be cleaned before install , a lot of material left on the insides.
I did clean and smooth this one out. I didn’t do a port and polish or anything like that but I did clean up the casting mess. The s&s one was even worse casting junk.
Have you done a dyno to compare the cam and stock manifold to cam with cast manifold? How is the seat of the pants? Did the HD cam in my 18 heritage amd Reaper 465 in my 17 SGS, and debating on swapping manifold at 10k on each bike. The whole plastic just annoys me and to get a cast piece just says longevity IMO.
@@ontwowheels6479 thanks. I had the SGS tuned with the PV and wow, she runs awesome. The heritage is all done with SE Tuner and the autotune module, still think there is some power left on the table.
Guys have seen 2-5 hp depending on the combination. I'm doing on my 107 RK with SE 462 but am also taking out the cat @ the same time. I'll do some logging for the SE smart tune & re dyno it.
Yes but I already had the screamin eagle tuner. I probably could have gotten away with not tuning for a while. It’s a minimal change but I do believe it has more power than it did based on feel.
