Ok everyone, I finally had the chance to shoot 4 of my Frankenbows thru a chrono and quite a few of you wanted to know what kind of speeds I was getting so I am going to list them now. I will name the bow and add a pic along with the stats of each bow.



2006 Energy with #7 Rev Cams AP Snow Limbs and White powdercoated Riser.

35" ATA
8 1/2" Brace Height
27 3/4" Draw Length
71 Lbs
80% Let-off
352 grain GoldTip 30X
293 FPS

When I first shot this bow today my jaw dropped... it is quiet, smooth and has no hand shock what so ever. It is one of the best shooting frankenbows ever built, and even though it has a 8 1/2" brace height, 71# and a 35" ATA I still got 293 fps actual speed with a 350 grain Gold Tip 30X arrow at 27 3/4" draw. This bow is only 5 fps slower than a XLR with rev cams that has a quoted low end IBO speed of 298 fps at 29" and I am getting 293 fps at 27 3/4".


2006 SBH Energy with Airborne Cams Lost Camo Limbs and Black Powdercoated Riser.

36 1/4" ATA
6 5/8" Brace Height
27 5/8" Draw Length
70 Lbs
350 grain Carbon Tech Cheetah
80% Let-off
303 FPS
Now that I have shot this bow I will be putting Envy cams on it, I bought it with Airborne cams on it and had to at least see what it did.


2006 SBH Energy with Envy Cams Black Limbs and OD & Black Riser.

35 1/2" ATA
6 3/4" Brace Height
27 3/4" Draw Length
70 Lbs
350 grain Carbon Tech Cheetah
80% Let-off
308 FPS
This bow has strings from another stringmaker and I will be building a new set for at soon, this picture is from the original owner and since it was taken I have installed a draw stop on each cam.


2008 Syn XT with Envy Cams (Synv XT) Mothwing Winter Mimicry.

33 1/8" ATA
7 1/2" Brace Height
27 1/2" Draw Length
71 Lbs
350 grain Carbon Tech Cheetah
80% Let-off
311 FPS

The 2008 Syn XT with Envy Cams (Synv XT) in Mothwing Winter Mimicry I built hoping that it would be a smooth drawing bow and maybe get me close to 300 fps, it turned out to be a very smooth drawing bow even with the Envy speed mods but I was more than jazzed when the chrono read 311 fps speed. We are talking about a 7 1/2" BH bow that is hitting 3 fps below the low end of the 27 1/2" draw Envy with a 1/2" longer brace height than a Envy, and with the speed mods it draws much smoother than a Envy with speed mods. I have 4 Envy's and none of them have a draw cycle like my Synv XT.

Anyway I just wanted to let anyone who had asked about speeds know what they are actually getting, Thanks for taking the time to look.
