Title: Cam Dilemma for 103
Post by: 86fxwg on October 09, 2021, 01:01:37 PM
Hears the dilemma,Sold my 2010 70000 mile FLHX that ran REAL good with a 110 drop in kit, Tourqe inc heads & his custom cam & other go fast parts, well im done with that!
Bought a 12 FLHX to replace it with 8000 Miles,DON't want to go balls out on any mods other than cam & maybe exaust. Exaust will be Ful-sac with V&H slugs that it came with, there quiet!

Question is (these cams i have in stock from take outs) don't even want to spend $$ on cams. zjust want a good running bike with a little more go rolling down the road.
TTS150(very little on the net about these in a 103) Most go TTS100 in 103.
SE 203 i took out of my old 96"
SE255'S
Dave Mackey TC575L (last choice)
My go too in this situation is the T-Mann 555TRQ's But Don't want to Spend $$ But will if all are Few bared.
Hardtail78 will tune it up w/TTS

If your staying with what you have listed, I'd use the SE255's. Tuned they pick up a little bit across the board.

Why not sell those cams off and then buy the 555s that you want?

The 574-2 was on the short list,If I wanted future upgrades,but that was short lived as I'm NOT going any bigger or faster!
Il look @ the 570-2.
Hard to sell the cams I have,that's the reason I took them out lol!
Wish there was more on the TTs 150! 
Wanna do this once & done.

I like this cam in a 96,but just seems to fall 9ff a little soon for my touring needs.

Been all over inner tube looking for Graphs & info on the TTS150,a bunch of info on 110" & up but nothing on a 103 stock. Steve says 2200 to 5000 I like this range,just like to have more real world experience!
Dam just remembered I installed these in a 103 that hardtail78 tuned for me before I pulled them to do a crank & 110 kit!  :slap:
Time to make a call!

If you could put in a .030" head gasket you'd be closer to the compression you would want for the 150. Probably need adjustable pushrods then too though.

Are Andrew's 48s and 57s no longer in favor? Done a lot of bikes using them. Pull well, tune easy.

It ends up being a hunt for the best in a sea of mostly the same and all capable if compression is adjusted.

IMO, the 57's need more compression than stock. They really wake up when you get around 10.3 to 10.5 to 1.

48's are popular. Cams tend to be the flavor of the day. Not many bad ones as long as they are properly applied.
Title: Re: Cam Dilemma for 103
Post by: Ohio HD on October 10, 2021, 01:10:49 PM
I might be tempted to advance the TTS-150's by 4°. It'll give you about the same cylinder pressure as the OEM 103 cams. And then can be put back at 0° if you added more to the motor later. In a stock motor, nothing will interfere.

Title: Re: Cam Dilemma for 103
Post by: Trev T on October 11, 2021, 05:49:45 PM
sell what you have, .030 gaskets and a set of TW 5-6 cams with a good 2 into 1. unbeatable power through the whole range. Have tried several different cam sets in 103/.030 D&D 2-1. the 5-6 is the answer and is very quiet also. 255's are hot, mackie's are ok. SE-203 would be as close to the 555's as you could get. Been in the same spot and used all of them. pulled a set of 5-6 from a buddys bike with true duals(installed S&S551). Good luck and post your results.

4* retard on the 255 could work too.
Title: Re: Cam Dilemma for 103
Post by: mike jesse on October 12, 2021, 11:37:08 AM
I can speak from personal experience with the SE 255 in a 96.
It ran really well and was done at about 4500 RPM.
Since I installed it into my then 2010 Road Glide it was a hard starter when heat soaked in really hot weather.

On a tight budget, I have installed the 103 HO cams from a 14 Street Glide into an older 96 and the bike had the same
characteristics as the SE 255's but pulled nicely to about 5200 RPM.

If I were to do the cam swap today in an otherwise stock 96 in., it would be the Andrews 48's and new lifters/adjustable pushrods. 

Stepping down. :smiled:

Post by: harpwrench on October 12, 2021, 02:37:21 PM
Out of the ones you have laying around I'd try the 203's, comparing all the specs (except for the top-secret one) it's a whole lot closer to the 555's
Title: Re: Cam Dilemma for 103
Post by: RTMike on October 13, 2021, 08:05:31 AM
I have had good luck with the TTS 150,have used them in a 110 and a 107 bothe nice numbers a a flat torque curve.the 555 are also a favourite here.
Title: Re: Cam Dilemma for 103
Post by: Hossamania on October 13, 2021, 08:38:17 AM
For me, I would drop the 150s in, just because I have them, and see how they do. I like to run my motors out, and don't want them dropping off like the 255s or 203s, so they have more appeal. If they aren't great, not a bunch of money spent, and knowledge gained.

Quit being cheap.  Get you heads to Capital for pocket porting and CC.  Shoot for 10.4, .5, and use the 150.  Save your money on a good tune and be done.  Do it now or do it later.  Too many fast bikes around Springfield you got your hands in to look at just a bolt in.  You can deal with guys having faster but they are gonna leave you like your standing still.  Then you are going to do what you should be doing now and I wont have to give up an extra Saturday if you do it all at once. :slap:

Is this a 96" or a 103"? If it's a 103 I'd leave it and do the above. If it's a 96" I like +.040" 103 pistons (leaves room for 1 more bore and hone to 107" provided the cylinders stay healthy) and do the above.

Little tough love from hrdtail... you guys must have done this before 👍

Details in OP, 103". In the title, actually.
I like the tough love, sounds like me talking my friends into spending way more money than they expected.

I ran Andrews 48 in my 2010 road glide. Great cams. But once in a while. Hard starting. Now I have s&s 551 easy starts in my 2010 road king. No problems.

Post by: gsxrboy96 on October 30, 2021, 03:41:39 AM
In my opinion for the money. If you're going into the cam
Chest. I just did a 103, used a .030 head gasket with a Andrews 54 , 2200-6000 and made really great power. The 255s sign off way to early for my taste. The 54 is also cheap a d you could grow into it in the future 🤷‍♂️... anyway good luck in the never ending quest for more power lol ..

The TTS works well with more comp and head work this build had 10.4 comp check out the rest of the build on the sheet.I use the 555 lots for stair bolt ins with an exhaust change they are great,you won't be disappointed.

We carry approx, $35,000.00 in cam inventory from Shovel, to M8. Fact.
The cam we reach for, and our client-base loves, is an Andrews 48 in a plug/play 103" touring bike.
If the heads are coming off, THEN you can let the badger loose, and see great power from that 103".

I see a Woods TW7H-6 for sale in the section, will that work in a stock '12 103, how will it preform compared to the CR 570-2, or the 48 that Hillside likes?
50,000 miles on the motor, potential for issues with the valves and guides being forced past their normal wear marks?

Leaving everything else even, the 7H would be slightly worse below 3.2K than the 48, and slightly better above 3.5K. ( about 6-7 horse improvement by redline).
They all benefit from a hi-flow AC and free breathing exhaust, and tune.

Something that hits a little earlier but still carries out to 5g or more, the 570-2 seems to fit the bill, and I'm not opposed to the 48, though I understand it shuts down a little early.

Specs don't help me, I can't relate them to performance, how does each perform, where is the power band compared to stock cam with stock heads, hi flow AC and exhaust?
A follow up question for Rigidthumper on the 7H, I like the idea of it carrying out, you say it's a bit soft below 3200 rpm, is it softer than stock cam, or about equal?
Title: Re: Cam Dilemma for 103
Post by: rigidthumper on November 05, 2021, 02:04:03 PM
Slightly softer than stock, by a only a couple percent- catches even by 2400, beats it from there up. Have you had the current configuration tested, to see where you are?

No, it's just stock cams, ac, decatted header with 3" Rhineharts, flash tune from Fuel Moto on a Power Vision. (S&S standard lifters with 30,000 miles on them now.) It runs good, "good enough". I don't want to go crazy on this motor like my other one, just a good set of cams and a proper tune. I don't race this one hard, but I do like to get on it, no fun after about 4500 rpms, hoping to at least get another 1000 rpm of power out of it, and gain a little low end. It's pretty good from 2500  to 4000, no real complaints there.
2012 Ultra Limited, 50,000 miles, time for tensioners. "As long as I'm in there, I might as well do cams."
The  CR 570-2 seems to be the one I'm looking for, but the 7H came up with a good price, just wondering how they worked. Thank you for the info on them.
Were I doing heads, the 7H would probably work fine, and the Andrews 54 would get a look as well.

I ran the A48 and the 570-2 in two separate 96" motors. The 48 was more snappy but fell off slightly sooner. The 570-2 was slightly less snappy and pulled a bit longer.

Great point.  :agree:  It's also a great way to compensate for a cam that's a little longer by spicing up the lower end performance.
