Wanted to see if anyone has these cams and what they think. Are these considered performance cams?
-
Any forum or any results I've seen posted anywhere, shows the TTS 100, more favorable in most touring applications. In the lower 2000-2250rpm area to 4800-ish rpms, but doesn't really just drop right off either. The 150 comes on a bit later and carries out well into the hp/tq cross, more of a mid-range cam. But I think it really shines in a 117...JMHO
-
Ok thanks. Is the 150 considered a bolt in or more performance cam?
-
The 150 needs to be installed at 10:1 and it is a good replacement for the stock cvo cam. Torque move but will be around a little later than the se255.

I have used the TTS 150 in a couple of builds with good results. Attached is a dyno chart from a 107" build I did with good heads and exhaust. Hit hard very early making one Ft pound per cube as early as 2000 RPM.
Pretty stout torque curve from a 107. :o

Now that looks sweet! Nice work
Steve you also recommended the Tman 625ps2 . I believe my compression is 10.5 - 10.7 only question is my springs are to 600. Would it still work?
-
This is a dyno with my budget heads, 110" 10.7:1.
Cam has 10 deg more duration about same lift.
Why not?

It has been a long time since I used a 625. Personal preference on power delivery more than anything. The TM 625 is quite a bit more aggressive than the TTS 150. Your compression is fine. The spring pack and valve to piston clearance @TDC will need to be competently checked. Your springs are advertised as "600 lift"? Doesn't mean a thing until everything is mechanically checked. The 625 is also going to cost you early low end power for what it's going to gain in peak numbers on the top over the TTS 150. Is that a good thing? It really depends on what type of power your after. If the budget allows, best bang for buck is always more cubes!
Attached below is a dyno chart from a 110" TM625 build I did back in 2014. That is what I would call an old school "square Build". The peak HP and TQ numbers are almost identical. Back in the day this was considered great. The "virtual reality" crew that regurgitates here would still give a thumbs up today. Those in the know would compare the TQ curve of the 110" 625 build to the 107" TTS 150 build posted earlier and realize the 110" 625 build below is a complete joke on the low end. In the real world of riding pavement, the 107" TTS150 would destroy the 110" 625 build in a 6th gear roll on even though it has 13 HP less on top. The 107" also makes 35 Ft pounds more TQ at 2K! That is a truck load! Today I would save the 625 cam for a 124" build.

Steve, a pipe change to your dx pipe and baffles would have the one I posted right there, higher aggregate torque, and still have another 10hp on top. Close lsa especially the intake LC accomplishes that. I agree on your comments about the low end torque and using cams that are too large for the build. We ride from 2-3k 99.x% of the time at part throttle. A dyno chart does not tell this story. The happy customer does.

I like that. Makes me wish I was closer. Not shipping a bike two ways though.

Monster Tq for a 110"! Wow! What cam was in this one?
Steve@fullsac.com

Tman 590ps2

So, for a stock drop in, factory compression, go TTS 100s or 150s? I always though Steve made the 150s for the 110s.
I had the 110s in a previous 110. Stage 2. They were fantastic.

This is another with a tts, 150 at 10.1:1, 117", my Street Pro 110 head package.

Awesome TQ from the hit! Good job Don!

Thanks appreciated.
Now the rest of the story..
Exhaust system:
Fullsac DX recored mufflers, 2.5" baffle2" baffle
It had 115tq at 1500, the red run.
Very few motor combinations, in my experience, will take full throttle in 6th gear at that low of rpm and not throw a big dip in the curve later to recover.
This is where credit goes to the combination with emphasis on pipe and cam. This was a very cool running motor as well with the low compression.
-
2.5 baffles? Holy Cow! 2.0 or even 2.25 baffles would improve the low end hit big time. Not that you need more. But if everybody is happy, better leave it alone!

Got the straight scoop from the owner 2" baffles packed. Fits the curve now. Sorry for the confusion.

I have the TM625 cams now, and this shows me what I am missing on the bottom.
When those 625 hit it's on, but too soft down low.
-
Since this thread was comparing the TM625 to the TTS150 I thought I would share my dyno
-
Unfortunately it is not fair to get too deep into comparing cam grinds or manufacturers when there are so many other contributing factors. The TR625 was developed when the 95" was popular and is a torque grind when it has the mating parts to go there including and especially the pipe and the needed compression. The close LSA and lots of overlap can cause the build to be somewhat pipe sensitive. When the heads are working well and properly sized for the demand I prefer a cam with wider LSA but still with an advanced intake LC in the 100 neighborhood. Despite talking about cams I am careful to not take the cam out of the context of the whole build.

Need some help with a tune.
First I have reached out to TTS but I understand that the covid restrictions in their area is making things hard for them right now. I have done the 117 kit on my 15 cvo road glide with the TTS-150 cam and tts mastertune. Header is Vance and Hines power duals with the OS450 pipes and quiet baffles. The only TTS-150 cam I find on the TTS website is for a 110 with 10.5:1 compression. I used the 0.030 head gasket and pistons are 0.007 to 0.010 in the hole so I am not quite sure of my compression ratio. I am ready to start it up but need a base tune. Should I use the base tune for the 110 with the same cam and high compression and change the displacement then run the flight recorder or do I need a better base.
If someone has a closer base tune that they can share that would also be great.
Last question is the quiet baffle in the Vance and Hines pipe going to be too restrictive. If so I will go to the 1.75 Fullsac with my old stock pipes like I should have done in the first place.
Thanks

You need to download the tuning manual. Read it completely. Use the 110 tune and adjust the cubic inches in constants. After you read the manual it will make sense. If it doesn't then I suggest getting the bike to a tuner that is very familiar with tts.
-
Yep plan is to get it to a tuner, but they are about 125 miles away. I just want to be sure its ok to start up and tweak for the ride down.
-
I would definitely go with the Fulsac 2 inch baffle kit in you're stock muffs
-

You will need to use flight recorder and data master to fix the VEs. First constants fixed, then road tuning.

Can I purchase this tts150 from you HD?
-
I suggest Steve at Fullsac.

Blown Alcohol - Do you know why your Dyno lines are so choppy, especially for smoothing 5? Those lines should be smooth and flat for the settings shown.
-
The guys at TTS got me a base map this morning, Started up fine. Now I need to learn the v tune process!
-
HDSP and Fullsac Performance,
Looking at my dyno graph in post #19 Which cam would you go with for this combo? CCP was 208/205. The TTS 150, or the TMan 590ps?
The 625 as Fullsac shows comes on late for a touring bike.
-
Looks to me, from whats been posted, you'd benefit more from the 590, than the TTS 150 in a 110
-
Try a baffle change. 1.75".
You have a high compression big head motor and now want it to come on stronger down low? The 150 does not like that high of compression. Local tuner had hell with a 120r that the guy tried to do the same detuning to. Very hard to tune and result was underwhelming due to all the timing pulled, heat!
Not a statement on the brand or the cams potential, but about the integration to get it to work as designed.
