Hello,
I have a question...
I bought a new setup this year and just ran it through the chrony today. I had expected a little higher speeds. Please let me know if I am nuts or not??
Hoyt Ultratec w/ Spiral Cams 31" draw
72 pounds
Vapor Trail string and cables
29-1/2" Gold Tip Pro-Hunter Carbons @ 443 grains total
290 fps out of the Chrony
Should I be happy with this or should I be getting more speed?
Thanks for the help!!!

Personaly I'd be happy with it! Not an animal on earth that is too much for that set up!
Do you have anything on your string? Loop, nocks, leeches etc? These will slow you down, and the bow is not rated with them on. And I cannot remember, but are their let off choices with the Spiral cam? You an bet Hoyt tested them at the lowest let off, maybe even 50% if that is possible on that cam. Higher let off shortens the draw curve a bit, less energy. Your arrow is about 83 grains above the 5 grs per pound that IBO is measured at. Your arrows are 6.15 grains per pound. I'm guessing, and purely guessing at that, that you are pretty close to what it should be in the real world. Also, how many chronographs have you tried? I have never found two chronographs that have read alike when used with the same set up....maybe the on you are using is a little slow? Then again, it might be fast?
I'm shooting an Ultra Tec with the standard cam n half at about 28" draw with a 450 grain arrow at the high 250's to low 260's. 64# or 65# draw with leeches and a loop.
I have some ACC's I am trying that are faster and seem to shoot well in my set up even though they are borderline underspined for my set up. Even broadheads fly well, but I need to test them some more. I have been led to believe that the cam n halfs like an arrow that is a little overspined, but so far the results with these arrows don't confirm that.

Who cares ? . The deer won't know the difference between a few fps . ;)

Damn, you are a beast. 70 plus pounds with the spiral cams? You are running more than 80 grains over IBO and still able to get in teh 290's yes you should be happy. You could easily get in the 300 plus range by shaving 15-20 grains off your setup. Me? I think your setup rocks.

If your arrow flies straight and finds it mark then that is all that matters. I dont look at speed, I like to look at kinetic Energy. I think you have plenty!!

IBO sppedes are based on completely stripped bow woth nothing on it . pulling a full 30". you setup with a shorter draw and pulling 72 # seems very good.
People get enamoured with how fast a bow speed is. My question is how quiet is it?? thats what counts.
If you want to pick up more speed you might want to turn you bow down in poundage in 4# increments. sounds strange that you can pick up speed by turning it down, but depending on your arrow and grains shooting , sometimes this will work . It promotes (in some( a better arrow flight and hench better speeds.
If you are shooting QUIET in the 240-290 range you shoot be VERY happy.

Give me a heart shot at 150 fps (my original speed in the 80's with a Darton SL-50) anyday over a 290 fps miss ;) <----<<<

I know a lot of guys say speed doesn't matter...but take a look at it this way: For every 2fps you gain, that is one pound of draw weight you can shave to equal the same KE. So, all things being equal, a bow that shoots 10fps faster than another, can be shot with 5#'s less draw weight. 10fps is noticable to an extent..but would be missed by most, but 5#'s less draw weight sure feels good in early November during a 20 degree day after a 4 hour sit.
Another angle to look at as well. Most people can shoot better with less draw weight..a few pounds usually are not noticable, but several pounds can be a big aid. But, take into count a Mathews Black Max that can literally be shot 12-15#'s less than a Switchback to get the same speed, same arrow, same draw, same KE.
Bottom line, with todays great bows by several companies, there is absolutely no need to shoot a slow bow...but the bow in the beginning of this thread is a screamer..no need to worry at all!! Probably a better guage is that if a person can't pull their bow straight back, with no movement other than their draw arm, they are over bowed. I know some "sky-drawers" around here that love to pull 70-75#'s but can't help but bring their bow up to a 45 degree angle when they draw....too much bow!

82.75 pounds of KE and your complaining what are you hunting for? That is awesome

I have no idea how fast my bow shoots , but I'm very satisfied with the accuracy .;)

Plus, chrono's are not an exact science. Try shooting through two other chrono's of a different brand and see what you get. You will be suprised at the difference.

Thanks for the feedback guys!
Yes - I have always drawn a bow back straight, well maybe night always. But after 23 years of bowhunting, I have learned that much. I enjoy watching the guys that need to get a running start to get their bows back, though. It is quite entertaining... :lol:
Yes - The bow is quiet as well. I would say it is as quiet as my last two Hoyts ('03 Razortec & '04 Xtec) with the standard Cam-1/2's.
Yes - I have no trouble hitting what I am aiming at (so far) out to 45 yards.
Just because a bow is fast doesn't automatically mean it is not accurate, the owner cannot shoot it well, or it is noisy, you know... :p
Back in the day...late 80's...I shot a Hoyt Proforce Extreme at 92 lbs. with a 6" overdraw and the "new" carbon arrows. Now that thing sounded like a .22 going off! :yikes: It blew through shoulders like butter though... :lol: Ah, the things you do when you are young and stupid(er).

"I have no idea how fast my bow shoots , but I'm very satisfied with the accuracy ."
That would just eat me up though if I knew I could be shooting a bow 5-7#'s less to get the same speed, accuracy, and just as quiet...with a faster bow.

i used to be caught up in the fps frenzy. with a 27 inch draw to get big speed i had to krank up the poundage and lighten up the arrow. then i got older and wiser. bought a hoyt ultra tec set it at 60lbs and shoot a 420 gram arrow at 245fps. this set up is the most enjoyable bow i have ever owned. oh and it kills deer real good.
