Trying to figure out which cam is going to be the best in my bike. I have a 2012 RGU with a Pro Race Stage 4 103. Heads, 259 cam, larger injectors, 58 mm throttle body, and most importantly 10.5-1 pistons. Here are the specs on both cams:

600 SM

Open Close Lift Duration Centerline TDC LSA Overlap
Intake 21 39 600 240 99 198 100.5 40
Exhaust 43 19 600 242 102 183

577

Open Close Lift Duration Centerline TDC LSA Overlap
Intake 20 46 577 246 103 196 104.5 38
Exhaust 50 18 577 248 106 171


I want a cam that comes in at around 2500 rpm and pulls to 6200 rpm. The Harley 259 cam sucks

Have the 590 T-Man in mine and its goes like a raped ape. You do have to stay on the revs though. Comes on big right at 2400 - 2700. And it doesn't fade what so ever. Great cam for a little on the aggresive side riding :eek:

Look up FullSac Performance, dyno sheet of my "Skunk" with the 600.
Bike is unbelievable and Steve will answer any questions if you give him a call

Very Happy with the T-Man 625s in the 117 (10.4-1)!!! The 625s come early and stay late!

I talked to TMan this afternoon actually. They recommended the new 577 cam. It seems to like the higher compression more than the 600SM. I guess thats the one I'll go with. It's a midrange upper end cam that is streetable. It has great low end torque as well with my setup.

He said it should solve my power issues. My bike was dyno'd at 106/106 when it was tuned. Kinda low for all the upgrades.

If you look on Tman's facebook page this cam pulls these 100/110 numbers with a stock engine, tuner, and exhaust. All I could say is wow when I talked to him.

That 577 looks like it wants about the same squeeze as an S&S .585.
That said, a 107" of our's was recently dyno tuned at Thayers Sales & Service, Corfu, NY,.
Our Stage IV Heads/S&S .585/55mm HPI/Thunderheader.
Went welllllllllll over 120 hp and torque.
Client from Rouses Point, NY can't keep r/tires on it.:)

From the cam specs the 600sm would work better for you.
@ABDC 39 on 600sm which means your TQ will come in earlier.
I hope this helps you out on your question.:D
Thanks FD

What kind of power are you making with the 117? I saw that 625 cam. I think I would have to upgrade my heads to run this cam. I like it though.

Frank, have you tuned any of the 600sm's ? I was looking for a cam with similar specs, and all the sheets I have seen which are few, were under achievers
even with mild head work.

Thanks Daren

I have the tman 625 in my 107" at 10.5-1 basic street port to the heads. Different valve spring to handle the lift. It puts down around 115tq/hp. My dyno sheet should be in the dyno section under Frankenglide if you want to have a look.

Yes we have used it many times.
I can post Dyno sheet next week
It likes 10:1-10.6.1 compression

'Don't really know, as the 117 has not been on a Dyno.

Other than a mild curiosity to see how the #s / curves correlate with the butt dyno, I am in no hurry to spin a drum with this motor...

Guessing (at least) high 120s both #s, with the tq coming in at 100ft/lbs around 2200-2300. Still have the rev-limiter at 5400 (have to get some software because of the DD7)

Since we were using the T-Man Cams, it made sense to have T.R. love on the heads, so we had him do the CVO Street Performer Headwork on the 110 heads, Also had T.R. Port Match/ Polish the SE 58mm TB.

Very Happy with this set-up for the way we use this bike (Sport Touring)

Threads on other forums got me to looking at the T-Man 625s, they have quite a following, with some dyno sheets.

Trying cams other than the T-Man 625s is not on my list ~ they work very well for me.

JMHO, your results may vary...

Cool, spec wise they look like they would do well in a moderate performance build, but I have yet to see it, I like the TR625's at 10.5, but that requires head work.
Frank, make a 590 lift version of the 625 tman, and It would be a hit.
