We had this one brought in after a dealer tuned the bike.. The WOT pull is on there to how how it was. That really was a good afr curve compared to how the rest was.. Dealer talked customer into a 625 the first go round and the bike was not running great by any means, they swapped the 583 for the 625.. He was stuck with what they would do for him.
Ex system is a crusher power cell head pipe and crusher mufflers. Tuner is a SEST..
No engine work other than cam swap. Bike pulls like extremely hard , and really runs well.

That looks pretty nice for a cam, pipes and tune.

steve,
i didnt realize you were only tuning to 5000 rpm these days. The factory rev limit is now 5800 without any devices added :) I think you made need to borrow John's glasses you missed 800 or so rpms.
-
we use alot of the .583`s,their a very nice cam for milder builds
-
Certainly the result is impressive for the type of guy that wants stock type torque but to accomplish that this cam has an 18° intake CL and 98.5 LC. The stocker cranks at 220 or thereabouts PSIG I would be curious to see what influence this cam has on the CCP and how they will fair in this motor at sea level in the heat. The same result can be had with a Wood TW5-6 or Tman 555 Torqster but they still are there at 5,500, maybe this cam is too but in this test we don't know. No need for head work if this class of cams are utilized (in the context of the 110) and the CCP will drop to a more manageable value.
-
The engine was done by 5000 I did pull it past previous to that but no reason to run it higher. As for running in hot temps,.. well it lives down in the valley. Customer called today to let me know how it did.. Result was no ping and it is running just fine on the 89 octane pump gas. Temp today was 103 , will be in the 110 Plus next few days.
Customer likes the power where its at, zero cam noise.. Some guys just dont care what the engine does in the 5000+ area..
So a cam that makes more power up there is worthless to that guy.. ... please post a link to those sheets showing the 5-6 and the tman in stock 110 engines,.. would be great to see..
Is it the best cam , depends on your needs, for this customer ( the guy that pays the bills) it is just what he is looking for.. I did over lay the 57 graph on top of this one can post that up later.. But down low this one has it by a larger margin until the 3500 mark..

If what you say is true this cam is a winner for the guys looking for punch.
I am not sure what we see is what could be expected in every similar case? The tune was not as developed as yours therefore the incremental gains from a well tuned stocker equipped with the stock cam VS this cam changed version may be less.
89 octane..
This cam sure produces a better result in a stock 110 than the 54. The TW48 is a better comparison however another one to throw in would be the 551. The 57 is a different class of cam as we both know.
-
At least on this side of the country, we pull the engine until the hp curls, to see the entire picture.
Carry on.

I would fall in that category. In fact have said more than once don't really care what happens beyond 4500. It's a big heavy bagger geared such that even quick passing a truck on the two lanes just doens't run that high. It's refreshing to see a shop also offering and explaining product with an eye towards how the bikes are ridden rather than toward the hyperbole of making the next sale. Of course you'll be criticized for being part of the great unwashed who dare to care not about comparing. But, what the hell, you offered all the data for all the areas I'd ever ride the bike. I'd never care about the rest of the BS anyway. No matter what side of the country I was riding on.

AMEN BROTHER!!!!! :drink:
Be Safe
THE DAWG

Well since i was really only busting on Steve and it was taken out of context as an inside joke about using John's glasses. In any case I would still want the final dyno pull for WOT done for the sake of knowing that in the event of getting a wild hair that the bike was safe or in the event a shift is missed that the motor is safe from a tune perspective.

:pepper: :pepper: :pepper: So many cams, so little time. Looking fwd to the 57 overlay but since we're on the outside looking in I'd really like to see how the Fullsac "C" x pipe and 2" baffles work with these cams. I know..that opens up a whole new arena and you can't do every combo of exhaust and cams. It just seems that a lot of guys running cams in this range would be curious how they run with the X pipe. Ok...maybe just me. How about you Steve's getting together and sharing resources. ;D :2vrolijk_21: :2vrolijk_21: I'd say use mine as a test bed but I won't be stateside til late August.

It seems every dyno run with the Kuryakyn Crushers seem to turn good numbers- maybe they are an overlooked and under rated slip on choice.
Btw,the little digs and put downs between the various shops on these threads is getting a little annoying, IMO.

6th gear pull. I would have shut it down at 5K too.

Can you tell me the difference between this cam and the stock 255's?
-
If you look at the first pull you will see power fell off. Once I was done tuning it did not change much in the higher RPMs. The graph is just starting to drop right where its at.. LOL Thus no sense in spooling it up to show what it will not do :nixweiss:.
Funny ( unbalanced, its a inside joke guys) HA HA .. Not there yet, but John has a killer set of coke bottles though.. :huepfenlol2:
I will see about posting up the other sheets.. not sure why though.. I am comparing it to what?? to show that it stopped making power..
The cam works well for what it is.. If you want a cam that makes more power at higher RPM's look else where....
I was not trying to compare this cam to another or have some one tell me about how well something else's works.
If someone else has any real hard info, along with the visual data to back it up, lets see it. Be great to see how the curves differ..
In a nutshell, if you want a low cost , basic kit , run on crap gas, in high heat, this little kit works fine.
It may not be for everyone, however I can say that the customer has called back again to tell me that even in the super high heat, it did not ping. So even with the early close point ( the CCP programs do not tell you much) it works..
Have a good one , stay safe.

Where most of us ride 95% of the time anyway!
Nice power!
