I' m shooting a 2002 Hoyt Cyber Tec w/ versa cam at 65lbs, and 29in draw length.
I also have a whisker biscut rest and shoot Carbon Express arrows Terminator hunter. I have chronograghed speeds of 242 fps.
I' m looking to increase my speed, any suggestions?
My is used 90% of the time for deer/bear hunting.
A friend mentioned shooting lighter arrows possibly Eastons A/C/C, any thoughts.

Take the whisker biscut off and replace it with a MZE or Bodoodle pro lite and you will gain some speed.

Going to a lighter arrow will also help but they do loose more energy further down range than the heavier arrow.

What are you wanting the speed to do for you? If it' s flatten out your trajectory, how much more speed do you think you need to get there? 10 fps? 20? It' s good to have a goal to work toward, so you can plan how to get there and make decisions on whether or not it' s worth it.

My bow will shoot a 375 grain arrow at 288, 500 grain at 252. At 30 yards, the 500 grain only hits close to 4" lower than the 375 grain, not to big a difference.

The CE T hunters are built heavy to provide more momentum and KE when launched from the same bow. Going lighter on your arrow will get you more speed and a slightly flatter trajectory (depending on how light you go), but will cost you KE and momentum, which has the POTENTIAL to impede penetration over your current set up.

What isn' t your set up doing now that you want it to?

Whether it be fast cars, fast women or fast bows, speed is nice. You could:
up the poundage
remove a peep sight & or kisser button - go with a No-Peep
go with a lighter arrow
go to a lighter broadhead
plus a few more I' ll think of after I post this.
The problem is, everythings a compromise, lose weight - gain speed but lose momentum. Would you even like a No-Peep? Sometimes it' s not the investment of $, it' s the time that you have to put into it to find out if the change will suit you. If you can, take it slow to take it fast. Too much change at once can affect form & confidence.

Also here' s some #' s that somebody posted somewhere before. Hope it helps:

These figures can be translated to increase or decrease depending on whether you are adding or subtracting them from the bow.

7- 10 fps for each inch draw
1 fps per 5 grains arrow weight
1-2 fps / pound draw weight
Fletcher Peep = 3-5 fps
Plastic hunter peep = 5-7 fps
Rubber peep tube = 5-12 fps
Rubber cat whiskers = 5-15 fps
Tied D-Loop = 1-4fps
Brass nockpoint = 1-3 fps
String leeches = 1-2 fps
Brass nocks placed near the cam(2 or 3 crimped on)= adds as much as 8 fps, but you may have to play with placement to see the speed change. If not placed properly it will cost you speed. Generally speaking, 2 nocks placed about 1/2" above the spot where the end of the lobe contacts the string (one cam) you' ll gain about 3 fps. Best done w/ a chrony at hand.
Magnocks = 3-5 fps
Feathers vs vanes - 5-15 fps (velocity equalizes generally within 35 yds)

If you have access to achonograph you can play with all kind of things. I know on my 2001 Ultratech I have the versa cam, and I played for hours on that thing. Adjusting the let off and drawlength, I finally got a setting that gave me an extra 8 fps. I do not know how this is possible but the cronograph was consistent when I made changes. The versa cam is a little goofy in that if you adjust the let off pin it actually adjusts the drawlengh slightly by adjusting at what point in the draw cycle the stem from the cam hits the string.

You can also play witht the speed nocks on the string, different arrow nocks. I wish I had a chronograph I miss playing with my set up.

How heavy are your arrows that you currently shoot?


Good Luck

Your arrows are pretty heavy. That line of Carbon Express is pretty heavy! Go to the Carbon Express CX line and you' ll gain a bunch!

Good Luck!

I think Cloud 9,mn has the best way to come speed. I shoot about a 430 grain arrow and that is only at 10 gr/in. Just a quick guess but you must be shooting around a 480-500 grain arrow. You should be able to nock of at least 30 grains and possibly 50 if you are shooting 125 heads and switch to 100 grain heads. This should still leave you with a pretty good arrow weight. Don' t you just love it when you aska question and people give you good advice so you can go out and spend more money

Thanks for all of the suggestions!
I recently had my arrows(Carbon Express Terminator 6075),checked for weight and spine at my local pro shop/range. The Spine was at 92lbs for all the arrows, not 60 -70lbs as stated. There was at least 12 grains of difference in weight on 3-4 arrows.
I emailed the company today and I await their response.
Any one else experience such a discrepancy with the spine of their arrows?
If so, does one need to bring a scale and spine tester with him before purchasing arrows?

Mean while the guy at the pro shop recommends Easton A/C/C arrows.
He said it would give me at least an added 25fps, which would put me in the 265fps range.
