S&S cams w/ dyno sheet
« on: October 27, 2010, 09:09:05 PM »


Blue = stock 110”
Orange = S&S 551 cam
Red = S&S 583 cam
Green = S&S 585 cam

I was doing some research on cams for the 110 and the good folks over as S&S sent me this.
Thought I would share and see what others thought.
Looks like the 583 cam could be a nice choice.
I have no information on the bike used in these dyno runs.
The person I spoke with just said it was a CVO 110.
I am leaning toward the Feuling 574 cam.

If you take the area that most of you ride in and toss out the high RPM stuff the 583 looks nice. The stock cam looks to be pretty good as well when looking at the overall curve shape and area under the curve.

I am Sorry about double post Please Delete one of them

583s are the cams my dealer recommended for the 110, considering I want low-end torque over high-end horsepower.

That is the paper tiger, so to speak.
On the road I bet the 585 is a lot more fun and still has adequate low end torque.
Disconnect the ACRs with the easy start cams. No need for both and at altitude it may not start on you.

I guess if you ride consistently above 4500 rpms, the 585's would be fun.  I'm rarely, if ever up in that neck of the woods, so they don't appeal to me.

So I have a question re: the printout.  Some dyno sheets show very smooth lines whereas others (like this one) the torque lines are rather "wavey".  Is there any reason for this i.e. does this indicate anything about the tune job?

I am no Dyno expert,but I believe it has to do the smoothing setting on the dyno.
Smoothing scales run 0 to 5, with 0 showing the most detail.If the bike is tuned well, there will be a smaller difference between 0 and 5 smoothing.

:devil:

I ran 585s in a 98" dyna and didn't need to ride above 4500 RPMs to have fun.  They were a very well-mannered cam, very streetable, no hot-start issues and delivered what I wanted.  In a 110, I think they'd deliver even more low-end and be an outstanding choice, especially if you like to twist it on occasion.  Power delivery is linear, smooth and deceptively quick. 

Remember, the R&R 615/585 that everyone loves is an S&S 585 with more lift on the intake and two points more on the intake close.  IMO based on the charts I've seen, the 585 with 1.7s on the intake will deliver even more on the bottom than the 615/585s and won't be giving up anything of consequence on the top end.  My point - S&S 585s in a 110 would be a great choice for a cam if someone is looking for good, solid performance, good streetability and no PMS.

 R&R 615/585 that everyone loves

Hold on a second, gear drive only for small cam bearing (pre-06) motors, right?
Do you have any actual case and points of the 585 in a 110?
This motor by virtue of stroke\ bore and heads is very different from your 98", plus is geared a lot higher and most are considerably heavier.
It is not my goal to discredit your post that cam has it's place and does well but I think there are better for the 110.

With the proper compression, cylinder head flow, intake and exhaust, the S&S 585, WILL show very good power.
The E-Z start feature is a money-saver for those that do not have releases.
Just completed a 107"er that the client requested the use of that cam. Showed great power, over a very broad band, with it striking very hard, off the bottom. :)

As it would with OEM ported heads, I agree the cam has it's place. In the 110 there are better plus the CVO heads already has ACRs, no need for the easy start feature.
