Title: FPS with 08 General question
Post by: Clark33 on March 24, 2009, 07:21:40 PM: I got my 08 bowtech general a few days ago. I really like how smooth and quiet it is, but i am a little confused by the fps I am getting. Here are my bow stats:

Draw Length: 29.5"
Draw Weight: 70#
Total arrow weight: 366 grains with 2" Blazer vanes
Rest: Vaportrail drop away rest

No limb suppressors or string suppressors.

Right now the chrono we have says i am shooting 265fps.
Shouldn't this bow be shooting in the mid 280s fps with this set up? May be the chrono we are using but I don't think it would be that off.

My black ice with 29"/70lb draw will shot 420+gr arrows around 280fps and the general has about the same IBO speed. Make sure everything is tuned right and try shooting a different bow though the crono, I have seen them throw bad #'s and some times not even read :twocents:

Forgot
What mods does the bow have? if its the smooth mods then its about right.

Post by: bowhuntin on March 26, 2009, 05:42:57 PM: My general is set at 28" draw, 71# with an arrow that is 420 grains. It also has the smooth mods on it and the chronograph said it was shooting right around 260 fps.

Post by: Jason on March 26, 2009, 05:50:00 PM: You have to go with speed mods, with speed mods you should hit 280- 290fps with 366gr arrow, my Allegiance is set at 72lbs has speed mods and shoots 468gr arrow at 284fps.
