A question for Nitro Cam users

[davik]

I have a new nemesis and it came with the 3S cams...my question is; The 3L cams set at 27.5" (shortest post on the module) and the 3S cam set at 27.5" mmiddle of the module...which setup will be faster? or will the speed be the same?

I believe the 3l cams lowest setting is 28.

No...the 3L's go to 27.5...I have both on different bows, and the 3L cam is 27.5 to 30.5 and the 3S cams are 25.5 to 28.5

Only true way is to shoot them. On different bows presents other issues to consider. Both Nemesis then they should be close.

Close isnt the problem...I'm trying t figure out how close...if there's an advantage to going with the bigger cams on this nemesis, I'll change, but if there's no difference then I won't...I know the smaller cams made a poundage difference on this bow, which equates into speed, I just don't want to have to spring for new cams, etc unless the difference is appreciable. Right now, I'm pulling 60 pounds to get the same speed as I do on the Onza (bigger cams) at 54 pounds...

The large cam is naturally going to give you more speed for a given draw length and weight. I haven't seen a 2013 bow yet, but I assume they have changed the designation of the cams. What was once a 2.0 cam must be the large one (L) and 1.5 is now the small one (S). I have no idea what the number 3 means.
However, the larger cam will give more leverage to roll it over so the rule of thumb is that the draw weight of your limbs will drop ahout 10# from what it is now. So if your bow is maxed at 60# then it will drop to 50# or there abouts. In other words you probably have to change limbs, too.

Ball park figure for the new cams is $300. New limbs will be about $150. Then you need a longer string (cables will work). Now ask yourself if a gain of about 10-12 fps is worth upwards of $475.

A few things you need to consider in the differences between bow structure and set up;

the Nemesis has a longer ATA, which also equates to more string weight and slightly slower speeds than the Onza if everything else is the same, its just physics.

Other things to consider are the brace heights, is the Onza's brace shorter than your Nemesis? are they the same? A shorter brace will also give you slightly faster speeds as the the string has more time to inflect power and momentum into the arrow.

Are your let off amounts the same on the bows? The way to tell is to measure your hold weight at full draw, subtract that from the max poundage of the bow as it is currently set up, then divide that number by the max draw weight. A higher let off percentage will give you slower speeds.

Lastly is add ons; are the strings setup the same? Different peeps, d-loops, silencers, etc., along with more or less serving for your centers all have different weights. The more weight on the string the slower your speed will be.

In other words there are a lot of factors to speed, even if you were comparing a Nemesis to a Nemesis (which you are not) how they are set up can give you completely different results.
