I don't understand the point of the secrecy.

Warranty 
That is what I was thinking.

Like I told WAPITIHUNTER in a PM. I bet it has been a fun experiment but I wouldn't want to do it with one of my bows.

Pretty amazing what these manufacturers are doing these days. Wasn't long ago when guys were chasing 300fps.
Here's what WAPITI's monster would do with a WA legal hunting arrow
Bow's IBO Speed: 365 fps
Draw Length: 30.00 inches
Draw Weight: 80.00 lbs
Weight on String: 15.0 grains
Total Arrow Weight: 480.0 grains
Calculated Speed: 336.67 fps
Kinetic Energy: 120.84 ft-lbs
Momentum: 0.7175 slug-ft/sec
Just in case anyone missed the link I posted before this is a pretty cool article explaining what it would take to produce a 400fps IBO bow. Not going to happen anytime soon.
