Just for reference, with my stage 1 breather, 222 cams, 2-1 pipe & dyno tune with SEPST, I'm +22hp/+18tq over stock.

I had it dyno tuned after the cam install with my V&H slip-ons I had before the Fat Cat & I just wasn't getting the benefit of the cams so I decided to go 2-1 while I had it in the shop & it paid off big time.

 

Don't make me swap my 555 for 222, those are impressive numbers.

 

128auto, sharkman, johnny, thanks guys. Those are some good vids. That 555 has got quite the impressive lope, but I will be going with a 2-1 system so I'll bet they'd sound a bit different with that set up. Two very good cams for sure. I haven't decided if/when I want to do head work. I'll bet the 222's would suit me just fine, but the 555's would do the job in the long run.... So many choices and options with cam picking. Thanks for the video posts!!! Anyone have any feedback on the 204's by chance?

 

What was "stock"? What was the baseline run before the mods.

 

555 with 2-1.

 

Gearing is the same for both bikes. The Fatboy is about 40lb heavier. A 40lb difference of the line can be enough to push you out front and keep you there before the Fatboy has enough time to catch up. The overall gearing of these bikes is 2.79 which can make even a heavier bike with some good mods a little lame from takeoffs. The stock cam and the SE-255 cam have pretty much the same HP/TQ profiles with the SE-255 just being more of the same as far as numbers go which a lot of guys like. I went with the Andrews 48H cam on my Street Bob and got 85hp and 100ft/lbs of torque. It's a blast to ride and will pick off many unsuspecting Big Inch motors. I know it will give my 117 ci Road King at 127hp and 130 torque fits in a short distance. Have fun with that Street Bob, I know I do!

Sorry. Your buddy's bike is a Wide Glide and a few pounds lighter in stock form and same gearing. It must be in his tune. He may only be 5-10 more then you in best tune with the SE-255 cams.

 

Bone stock on dyno:
64/78

Stage 1 breather, V&H slip-ons & dyno tuned with SEPST (done at 1,000 miles):
74/88

TW-222 cams, D&D Fat Cat w/big boar baffle & dnyo tuned again with SEPST:
86/96

 

My recommendation would be that if you think you might ever increase compression at some point, go with the TW-555 or TW-777. If you are going to keep stock compression, go with the TW-222.

I've seen a few charts comparing the Wood TW-222 to the SE-204....TW-222s make slightly better number all the way through the curve. The curves looked similar though. The SE-204s have more duration, while the TW-222 has more lift. Results appear similar, with the 222 having the edge.
