i recently just purchased a Bowtech Guardian, i have a 29.5 " draw, and at 70 pounds it only shoots 286 fps, this is way slower than my tomkat at 298 fps. the arrows are only 400 grains! how can i get this expensive bow to shoot up in the 315+fps? any suggestions

You're right you should be getting more than that. I was getting 265fps with 330 grain arrows at 25.5". My short little arms are only putting out 20fps less than you, which shouldnt be. The only thing i can think of either your arrows weigh more than you think or the chrono was off. The only thing i can think of is taking thesilencers of and buying a string supressor so it isnt gaining noise without the silencers.

I don't know why you would want to. That change in speed means nothing. Yeah you'll gain some KE but the point is mute with what your already getting.

The only way to significantly change a bows speed is to increase poundage, if your maxed out you can tweak a bow to gain a little more but what you gain is offset by the means to doing it.

Or you can significantly lower your arrow weight and again, what you gain is offset by what you lose.

I ask again, why would you want to?

Actually Mo, if you add 10 fps for every inch of draw length you're missing to get to the specs listed in the original post, you start out with 265 at 25.5", so you'd have 275 at 26.5", 285 at 27.5", 295 at 28.5" and 305 at 29.5"... Now add the extra 70 grains he's shooting over you, and you're both about the same... in fact, his isn't bad at all.

Take the 1/2" draw length off of jquillin's specs, and that cuts 5 fps off IBO specs. Add the 50 grains he's shooting above IBO specs, and that robs another 17 fps... that's a total of 22 fps. Add that back onto the 298, and jquillin's bow would be hitting 320.

But to Rob's point, I don't think the Guardian was ever intended to really be sold as a "speed bow"... there's others in the lineup that do a much better job at that (Allegiance, and now the Airborne 82 if you really want to push the envelope). The Guardian was designed to be the smoothest, most shock-free shooting experience ever felt at the time, and the only bow that's currently outperforming it in those areas is the '08 Bowtech General.

i am not dissapointed at all in the performance in this bow, it is the greatest bow i have shot so far and im glad i bought it. i just wish that the speed was a little higher. i guess if i went with a lighter arrow and a lighter broadhead, and different vanes, it would be smokin', but who cares i can hit a dime at 20 yards with it!! thanks for your input

Just keep in mind that IBO specs are always obtained with a 350-grain arrow (for 70-lb. bows, to achieve the 5-grain-per-lb. recommended minimum) at 30 inches... anything that takes away from that will rob you of the stated IBO speed...

If you want to be in the 315's with a hunting-weight arrow shooting at 29 1/2", I'd suggest looking at the Airborne 82

But here's the reality of it all: If you'd never shot through a chrono, you'd probably never be able to tell if your bow was hitting 298 or 310. The naked eye can't distinguish the two; it's more of a "macho" thing.

Remember this... Matt / PA and I were talking on the phone last night as I was coming out of a new spot I'd hunted for the first time, and we were chatting about the new '08 lineup Bowtech has put out this year. We were both getting excited about shooting a 450-grain arrow out of our new Airborne 82nds and talking about the outrageous speeds and KE we'll be getting out of them, when Matt brought us both back down to earth with a dose of cold, hard reality. He said, "Yeah, but I just killed the biggest buck of my life with an arrow that was going 145! And it slammed all the way through him!"

Yep, hard to argue with that!

grouping and consitancy is more importaint.IMO

Absolutely. I you can't shoot the bow speed means nothing at all.
