Building motor back with a zippers cam plate zippers 587 cams and zippers lifters. Im excited to see how she runs with the new cams.

I hope it serves you well :2vrolijk_21:
Keep us apprised

I having trouble deciding which cam to get. So many to choose from.
How about you, why Zippers?
How does it feel now that you've had it a while?
And, how's that baby sound!

I think we need to level set first
A 110 CVO, mine for example 2013 CVO RK, with an andrews 54 and stock motor makes 100/115 and has a very strong flat torque curve from 2200 up. Only change was a .030 head gasket.
Here is a CVO 110 with cam and heads, the cam is a very small SE 585

Also considering this cam or a bump in compression and a little later intake close.
That 585 dyno run is sky high numbers! I would think the two would be close, similar numbers on them. Not exact but on paper look to closely matched. 1 degree on intake close and .005 difference of lift

I am not sure what you are saying?
Here you see this is a small cam 23° over the stock SE255, 36 intake close 234/240. The head work and added compression compliment this cam well.

Don,
Which exhaust are you running on your bike
-
Not a CVO, a Dyna 110 S. Mine Stock exhaust minus cat, Kuryakyn TC 25D bolt in cams, S&S Premium lifters,adjustable push rods, Feuling Cam plate, TTS Master Tune. Tuned on a Dynojet,
94Hp - 111 Torque. My friends, same set up, except for exhaust. Stock head pipes, cat is MIA,
Cobra slip ons. His is 98Hp - 120 Torque. Both bikes run perfectly. Dave

Fullsac DX with recored stock mufflers 2" baffle
I had the SE585 in the bike before that and I am so damn fussy I just didn't like the intake noise so I went to the 54. The SE585 made almost identical power and torque but felt a tad better right off idle as I would expect with its earlier intake close.
Here is a backup to the last dyno sheet that shows another stock bottom end 110 58tb with heads ported and the SE585 10.4:1 which incidentally takes a fair amount of head cut. Understand this is not my favorite cam or cam brand, it just works with the characteristics of my CVO ported heads at 110", the combination. The same heads @110" or higher can make more power and torque and keep a nice torque curve by going up in cam, compression, and throttle body / injectors

Very Nice combo :2vrolijk_21:

Very nice. Did the clutch handle those numbers?
-
That is my 2012 CVO Street Glide , Slate Grey/ Black , same as yours.
You can see on the dyno sheet that the clutch slipped from 2100 to 2300 rpm and then locked up. You have to understand that this was a 6th gear pull at wide open throttle from 2000 rpm, you would never do this on the street. This is a stock CVO clutch, if you don't abuse it it is fine.

Thanks very much. I am sure that is fun to ride. I have mine in now for a little work and was thinking i would need to add the clutch cost to the build. So, I will wait and see....

I was impressed the se 585 did so well and thought the redshift cam would be close with its similar specs. Your second post mentions the head being cut but the first I commented on was only a gasket change to bump compression? That would be impressive jump.

Both of those Dyno charts are of my 110- 2012 CVO Street Glide but were done on different Dynos. First one done here in New Mexico with a Power Comander 5, there were a few issues with the tune. Second tune was done with a TTS tuner by GMR performance in Fort worth Texas, the numbers a little lower in Texas but performance greatly improved.
Numbers don't always equate to a good performing bike but a good tune does and that is what I got on the second tune in Texas. The stock CVO heads were milled .060 to get 10.4 - 1 static compression. this is good for where I live in high altitude New Mexico, if I were to live at sea level I think 10.2-1 would be ideal for this cam.
Hope this clarifies any misunderstanding.

Update...... so after my first post I tore my bicep and my labrum at work. So I had surgery and everything has been on hold. I get my bike back tomorrow. I had it tuned and 5th gear replaced. My specs are 113 tq and 96 hp with a fullsak dx pipe with the flat crossover pipe, v and h ho slip on pipes, 587 cams with a redline cam plate and a tts tuner.
