I am about to take delivery of a new 2014 Ultra Limited with a twin cooled 103 motor that comes with a 10.1 compression ratio.
I am going to have Doc install a Ful-sak XD pipe, Reinhardt 3 1/2" slip-on mufflers and H/D's Hi-flow air filter kit, and tune it with a Mastertune TTS 2.
He's done a few bikes for me already, and I've always been happy.
I asked him about cams, and he suggested I leave the one that's in their for now (it's not a 255, I'mn not sure what it is, but seems to have good low end power right off the showroom floor), But I dont want to have to do a re-tune, I'd rather change the cam now, unless the stock one is the better choice cam at the moment.
I'd like to get some other feedback about sticking with the stock cam or changing to another one, and which one and why.
I don't care about peak h/p, I want as much torque as low in the rpm range as possiable.
Andrews recomended using their 54 cam.

My new baby, can't wait untill it gets its new chrome wheels, rotors, forks, hand controls and a bunch of other bling to bring it closer to the CVO (couldent do any of the colors, maybe next year)

Please share your thought's.

And if anyone know where I can get a Mastertune TTS 2 for the best price, please let me know.

Thanks,

Contact Steve @ FullSac,,, He has a '14 TK for his personal bike,,, between Doc & Steves input, doesn't get much better than that, IMO

Here's some info about the 2014 "stock" cam

[TorqueInc]

TC561-2

  Has broken 100 torque @ 2400 rpm in both watercooled bikes it has been installed in,no woodzie torque spike and carries the torque to redline

[GMR-PERFORMANCE]

Steve I hope to see the new S&S cams  in testing   

[TorqueInc]

As soon as I get another batch ill have one on the way....maybe 2

[CVO2FIXUP]

 Steve, when do you think you will be done testing?

[remington007]

Steve...The Kury TC2D has a 50* close on the intake. I would think the stock flat tops would not yeild enough compression for that cam.

[FlaHeatWave]

The testing is set to start Feb. 11 here. How long it's going to take depends on what things need. With 20 + combinations I hope we could get them all done by the end of March. I figure a good week would allow us to get 5 done so there is 4 weeks + as long as everything goes smooth. As for what camshaft is going to do what that's not up to us. This is purely being done to develop base calibrations for our customers to use, the results will be what they will be. It's going to be one bike, one dyno and one person doing all the tuning. No effort is going to be spent to make one better than the other. They will all get the same treatment.

Does that bike have ESP on it?

All kidding aside; What an awesome project!

Steve,

Any Updates?

[HILLSIDECYCLE.COM]

Wood 6,  S&S .570.

[INDEPENDENT_1]

Not real super surprising but it appears the exhaust is controlling the curve shape more than anything else. Some of the cams are considerably different yet show similar curves at least at 100% throttle.

[HILLSIDECYCLE.COM]

What's the ccp with the 255 and 48's in those 10.0 cr 103"ers?
Scott

[Dr.D]

Would you expect much different results if the cams were tested on the 110 motors? Does the displacement increase affect the relative cam performance? I thought I liked the SS551 until I noticed it seemed to run out of overall power above  4500rpm. I was disappointed by the SE259e cam showing. I really like it it my 110 motor and it seems to be stronger in the lower rpm than you show. I wonder if the hc pistons account for that?

Is that the new lobed SE255? Are they still calling it that even though it has been changed?

Great test idea!

[Mr D]

Steve,

Any Updates?

Thanks Steve 

That's great info you've provided,, Really like to see the results in the wet heads

[GMR-PERFORMANCE]

Steve I want to thank you for taking the massive amount of time to builds all those calibrations. Peak numbers aside as that is a super small part of the work you have done,.. but the amount of new calibrations is over the top.  

[TNCarters]

Be interesting to see the results on the higher compression wet heads.  Thought I had heard the stock wet head cam was very similar to a SE255.  Dont know if twin cooled and wet head have the same cam but there was some difference in curves on the SE255 chart.  Fuelmoto has also been doing a lot of testing of different configurations.  If they do anything to the heads they seem to go toward the Woods 777.
(Posted at the same time as Steve and he answered some of my questions)

The Shower head testing got interrupted, since we were able to only use this test bike in this time slot. So we switch bikes and got the work done and now we are switching back to the Shower Head 103. The Air Cooled 103HO engine is NOT 10.0 compression ratio it is still the same old 9.7 advertised deal. The difference between the 103 and the 103 HO is the new camshafts and as you can see they do not perform as well as the 255 camshaft. While they are an improvement over the regular 103 camshaft still not as good as a 255. The 103 Shower head uses the same improved camshaft but raises the compression ratio to an advertised 10:1. This is done in the cylinder head as all the 103's use the same pistons. So for 2014 model year you have 3 versions of the 103 engine being used by HD.

As for how these camshafts are going to perform in any other application who knows, it all about the complete combination of parts that make the build. This test is only to develop base calibrations for our products that any one can build from.

  Thanks for confirming this...explains alot

[Dr.D]

Steve I sent a pm hope you got it.

Did you get to test some of the rest of the cams on you list, curious about the Fueling 574

[Classic Beast]

Thanks for the update, I really enjoy all your input

[Ridgerunr]

Lot of effort Mr. Cole. Thumbs Up.

That o'l .570 is still a winner. 

[Para Bellum]

I don't care about peak h/p, I want as much torque as low in the rpm range as possiable.

Many of us run the DX pipe, so that part of the comparison is valid. I don't know how much or what kind of change the Fullsac baffles would cause compared to the Cycle Shack SOs.  In this configuration, the S&S 551 provides the biggest increase in low-end torque:

RPM   Stock TQ   SS551TQ    Increase
2k       64               78             14
2.5      88               96              8
3k       93               98              5
3.5      95              100             5
4k       96              102             6

The 255 is very close to the 551, making just 2fp less at 2k and 2.5, and the same at higher revs.
