I currently have a Road Glide Ultra 103 with V&H Power Duals mated to Rinehart 4" mufflers, SE Stage 1 intake, Screamin Eagle Pro Race Tuner, and S&S 510 cams.  I like the power delivery and fuel economy of this combination...94hp and 104tq.

Fast forward to today and I have a 14 SE Ultra with the 110ci.  I have 1,100 miles on it and although I fell like the stock 255 cams do an ok job I would like more mid torque (2500-4500rpm) for our 2-up riding.  I want to stick with a Screamin Eagle cam for warranty purposes.

A couple questions....

My tuner has concerns with the high cranking pressures of the 255 cams...so what SE cam would give me what I am looking for without the high pressures?

Being a touring bike, fuel economy is important to me.  What SE cams will allow me the power I want to have but retain fuel economy?

Thanks in advance, Ernie

I think you just eliminated anything HD makes other than what you have already.

Installing just about any other cam - even an SE cam - can cause warranty issues. On the box my SE 259E cams came in, it said "For Race Use Only". Technically, installing them voided the warranty... but my bike went out of warranty as of the end of last month, so I don't care. Some dealers care about cams, while others don't make a fuss.

The Andrews 54H cams are very well-suited to the 110, and Steve George of Fullsac uses them in his Stage 2 CVO kit. I ran the 54H cams and the Fullsac X-pipe before I went to the Drago's 2-1 pipe - but I didn't feel that their 238/238 duration was long enough for the big pipe.

That said, I like the way the SE 259E cams perform with my Drago's 2-1 pipe. Not sure I would run them with anything but a 2-1 though... they have 246/250 duration and are more focused to mid-range and top-end HP than they are to low-end torque. They need revs! I also run the Cometic .030" MLS head gaskets to bump the CR a bit.

The SE 254E cams are lower-duration (224/234) SE cams that would give you more low-end and mid-range power than the SE 259E cams. They also have quite a bit less lift than the 259E cams, so they are perhaps not so good for the big ports in the 110 heads. They are very good for the 103s, but I don't think I have ever read anything from anyone running SE 254E cams in the 110.

I am currently gathering info on various cams, and am considering going at some point to either the S&S 570 or 585 cams, or to the GMR-Performance Genesis 577 cams. I don't yet know the specs on the GMR 577 cams, though.

I had originally purchased a set of S&S 583 cams for the stock pistons etc of the 110".
It was only when I inadvertently buggered an exhaust stud that gave me the "excuse" for the MVA heads/pistons etc that
I went with and the 259E for the warranty. Pretty pleased with the results, but yup, she does need revs to make power.
Don't bother me at all, as that is exactly what I wanted to build, as that's how I ride..
Pretty decent mileage too, trip meter (and hand calc) tells me I'm within spitting distance of 50 mpg when I cruise it (don't forget I'm in Can, so our gallons are 10% bigger).

I lot of riders want more low-end grunt than the 259E cams will provide. That's why I'm thinking of a cam change... even with the big 2-1 pipe. But like you, I don't mind turning revs to make power.

The new tune we did with the TTS Flight Recorder captured so much data - along with changing the timing tables to those for SE 260 cams and very careful attention to other things like EGRs, etc. by Mr. Wizard - have helped the low end manners so much that I might just keep the SE 259Es. It's MUCH smoother below 2000 RPM than it has ever been before with the SE 259Es. I'm kind of torn right now...

I talked to my tuner today and I guess one of the the biggest decisions I would have is whether I want to bump up the compression or not.  He said it really narrows down the cam options unless I do.  He said he has tuned a couple of other 14s and the water heads have reduced much of the heat.  He also said the 255 cams do produce the hp/tq in the areas I like and I may want to consider a good tuner, a dyno tune and then decide at some point down the road if I think I want/need more power.  He did wonders to my 103 and I trust him so I may just end up doing the tuner/dyno and ride it for 6 months or a year and then decide if I want to do more.

I guess I should also add I have a V&H Power Duals and Rinehart 4" mufflers.  I will probably end up using an SE Pro Race Tuner as I had great results with that on the FLTRU 103.

I have the 259E cams in my 13 CVO King.  I really like them.  However many other mods were done to keep good low end torque while gaining lots of top end HP.

I used 10.5 HD pistons, heads ported and polished and set for 10.8 compression with my pistons, 5.3 injectors and a 55 HPI throttle body.  Using a Fullsac DX head pipe, and 2.25 SD cores.  Over 120 on both torque and HP, torque is higher from 2250 rpm up than it was with just the pipe and cores, and a wider band also.

259 cam is a no warranty deal first off, second its a pooch cam even with the high compression piston kit. It still leaves so much more on the table. I have a set for sale cheap if you want them we take them out so often as the dealer talked the guy into the build we have to re tune it and they still are un happy with the power once its really tuned correctly. So back to the start waste of money. Until the guys that love the 259 cam ride something that makes really good power what can you compare it to??

Here is our cam vs the 259 . Stage III engine kit from dealer, tune was not really that bad from dealer it could have picked up a few but no way would it have gained what it has here.

Keep in mind that the dealer now sells street tuner to keep warranty on powertrain or pro tuner and HD is on board NO WARRANTY with install of pro tuner.. Its getting tougher.. I am doing machine work for a dealer now that is taking a 103 to the epa 110 and that will keep warranty if work is done before bike is sold to customer. Talk about huge money spent for minor gains all due to warranty I think its better to pay for something that breaks and have the power.. roll the dice but its not my money or bike .

So, looking at your dyno, STD smoothing 5, its not much different than my 259E cam.  Unless I am missing something, I am not a professional, or a builder.  It does show why I did not use the HD kit.  I do think I have figured out with the help of much smarter people why my torque went dipped and did not go quite as high as expected.  All the packing in both fullsac baffles blew to the end of the pipes.  I plan to do another dyno run now that I have screens to hold the packing where it belongs.  The holding the packing where it belongs has shown to help torque a few pounds.  Max power 124.69  Max torque 123.76

So what difference would I notice riding the bike you posted making really good power?  From what I see I make almost 13 more HP and 3.3 less torque.

Now if the bike with your cam has no other work but cam, I understand what your saying, but if it is a stage III I am not understanding.

Maybe you missed that these are stock heads and stock t/b .. I have tuned the stage III 259 kits and they dont make any where near that power without more and more money.. Cost vs end result. You paid ,much much more money for your build and what did you gain. HP from 4250 + up.. That is great for some guys and I can show you several more sheets with ( and another porter)  deweys heads this cam and t/b that makes more power than your sheet in SAE.. But that is not the point its about how a kit is put together and what it can produce.  Why not just bolt a 124 into the bike that will make mid 130/130 and cost wise it is not that far out of line.

This kit is very simple our cam piston kit ex system air cleaner tuner. Thats it. Most of these that I do the dealer has already installed the all the parts I just need to toss out the mid range cam and install something that makes power where 90% of the touring guys want it with the parts they already have.

One kit is not right and the other wrong just different.

Sorry I did miss that was stock heads and TB. That is very nice for and now I understand your comment better.

Dewey is who did my heads. 

For me, this bike has the torque / power right where I need it , 2600 rpm and up, normally the bike is cruising at 3000 rpm.  I have put 10,000 miles on the build in 7 months.

[GMR-PERFORMANCE]

Nothing wrong with what you ended up with.  But as I siad the amount of tq that is on tap with a more basic kit will really make you later the " I need hp " thought. I have ridden many of these and can tell you I dont see the need for the big HP number. It has way more than you really need and the bike 2 up tall gear low rpm roll ons will flat out haul the mail. It jumps and its stretching your arms pushing you back in the seat.

This bike has had passenger on it once, the parade of flags in Milwaukee for the 110th.  The other 10,000 miles since the build have been solo.  Most on day trips on twisty curvy roads.  This bike will not likely see much any more other than an occasional solo over night trip.

I have a CVO road glide for the long rides, but you sure have me thinking of that cam and a little compression for it......
