There are tons of threads about the BowTurbo on other sites. You should really do your homework. Most companies will void the bow warranty for using this.
Something else is that it increases the stresses on the limbs by increasing the draw length and adds poundage to the bow's limbs by increasing stress. At least these are the reports I've been reading. Just how much longer or how much more poundage to the limbs is still being discussed.
Just for comparison Martin added a CCS (roller guard) this year to some of it's bows and by locking the cables to a roller guard instead of a slide it does increase the poundage of the limbs. Therefore they have learned to reinforce the limb tips to accommodate this and the increased stress imparted by the Cat cam system.
In any case I would be a bit leary of using a BowTurbo simply because when the bow is drawn the cables are pulling backward on the rollers, which are locked to the rod, which is locked to the riser (supposedly in all three cases). If any one of them lets go you could be looking at a Identified Flying Object come right back at you.
X2!
Iwouldn't touch the Bow Turbo
