Nothing wrong with bottle on your blower at all. In fact, it's a huge increase in power, especially with gas.
Gas blowers have a really bad issue with heat. The more heat you have, the less air density. Increasing boost increases heat, decreasing air density.
You can literally increase boost to the point that you decrease power simply due to the rotors over heating the air.
Adding some nitrous into the mix increases the blowers efficiency by decreasing the air intake charge temperature (thus increasing air density).
The downside to bottle on the blower is backfire. Talk about 'banging the blower'. Hope you have some good safety straps (and a bag) on the blower or you may find it coming through the windshield.
