Why does someone have to have a certain number of post to be credible. I am taking my SESG with the CR-575's to the tuner Spartanburg H-D this Saturday. He is a week behind so it will be after that and I will post my results, good or bad. And I really will not give a crap if the anyone believes the results or not because they will only be for informational purposes for those who are interested in examining other variations of builds.

Way to work up the new guy Herko  :P

That cam does seem promising 3mcam- looking forward to seeing your graph.

Not to hijack the thread but is there any advantages between this CR-575  and an Andrews TW54 ?

Just a genuine request to know. I`m about to  install a tw54 ,after looking at the timing of the cr cam, am now second guessing my choice.

...looking at the timing of the cr cam, am now second guessing my choice.
The advance this cam has is one of its positives (as well as the intake close event) for the drop-in application.

I see statements like [paraphrased] "power comes on about the same place but I have more power on the right..."
When a bike has the ability to cross 100 TQ at 2200/2300 vs. later at 2700...this is more than "about the same" in terms of rider friendly power. Especially with our 2.79/2.87 gearing.
Yes, I'm aware of rider styles, shift preferences yada yada. But, you get the idea.

Sooo many times with our twin cam bikes I've seen the old adage be true...(especially in the drop-in arena) "The cam we think we want and the cam we really want are usually two different cams".

And, no need to mess with swapping head gaskets!

Cheers.

Just a genuine request to know. I`m about to  install a tw54 ,after looking at the timing of the cr cam, am now second guessing my choice.

I just got a tune on my RGC 103 set-up with the 255's, SERT, SE Intake, Power Duals, and Hi Output Mufflers and got a good  gain in both, 87 tuned to 93 HP and 102 tuned to 109 Ft.lbs. The reason beyond getting the SE 103 project finished is because I too am thinking about the SE 103 StageIV kit for $1800. New this month, it comes without the tuner as a seperate kit. I have read a ton and I still don't really know how it is gonna feel when a change has been made to the motor. So when the OP brings up a new cam that is like night and day, well my ears are all open. The HD 103 Stage IV kit gets u over to the 110/110 plus, although everything I read is that power all shifts over a few 100 RPMs, this CycleRama cam is of interest cause it doesn't make the move as extreme, but I'm guessing it won't do the peak numbers of the 259E that comes in the SE kit?????

Herko prolly knoes the answer for sure. my guess  would be a couple hp differance  maybe and tq would be close too. then how much cruising do yo do at 6200 rpm..   most of us ride at say 2300 -maybe  3000 rpm. the 259 is not ready  pull real hard  quite yet in a big ole bagger.  the 575 is already happy and is gonna get you out there and make the pass without tap dancing on the shift lever. that way you can keep picking your nose..  just kiding.

i have had a 103 stage 3 with 259E cams and this cam produces power at around 3,0000 rpm not good on a bagger. Always had to shift down to get and go. but when did it went. i am new on here just bought my first CVO am very curious on CR 575 cams and the tw -777 cam trying to figure out which one would be the best. am running se 255 at this time with D&D fat cat and a race tunner. very strong but dead at about 4000 rpm. had this bike dynoed and peak TQ was at 3500 rpm. at 4000 dead no more TQ.

Link above is a dyno sheet of 103 with CR575 cam (no head work or thin head gaskets)
Have not seen or read much on the 777 other than they work best with higher compression.

Very close to where I am at. 3 more hp than my 255's and 2 ft.lbs. tq. The 259E would actually hurt me without more fuel/air than my setup would give it I'm told. The stage iv kit has heads, throttle body, intake manifold, injectors, and some other bits and pieces... That helps with breathing that is supposed to make a 259E work... does the CycleRama cam set need more work, to make it perform at it's best, ie heads, bigger valves, compression increase, etc. as the 259 does or is it a bolt in  cam?

it will be close down low but on the with all your looking at doing it will begin to pull real good . spend a little moeny on  the 575 build and it works much better also.  thing is the 575 is for the people  that are happen with a good bolt in cam that don't require  all the other money  to make the 259 work as well.   the 575 will do real good also and if you ride like you stole the bike the 259 is prolly your choice, if not and your riding two up and a big ole heavy bagger the 575 in my opinion is a better choice, its all in how you ride not about peak hp where you are at for a splity second before ya bang another gear, and repeat it  four more times and  its over , when ya want to pass a coule cars in front of you or a big long semi and you don't have a lot of time and don't have time or want to tap dance on the shifter and maybe risk your life. its your call.

Dyno sheet after tuner. A little disapointed. Was hoping for more torque. Next step new headpipe, headwork and head gasket. Perhap then I'll be were I would like to be.

Wow!! I guess there are changes that we second guess ourselves about. What happened? This is a 110?
This graph seems low compared to a stock 110? What do u have for pipes, intake and tuner?

Everything is stock except I gutted the CAT from the headpipe installed a TTS Mastertuner and installed the CR-575 cams's. Can't really expect alot of improvement over stock with just Cam's and a tuner.

But what was it in stock form? It is supposed to have better numbers than that??
U stated that the seat of the pants feeling is stronger, and that is the most important!
And yeah with the intake and exhaust are reworked it may turn into a rocketship/with a Cummins Turbo Diesel
