The general rule of thumb is that you should never exceed 1/2 the engine's N/A output with nitrous. You can use the 300 shot on a 427 BBC, but they make 600 Hp N/A too. Still, a 75 shot should be Ok on a stock 13B

a 150 shot should be ok on a bridgeported 13B.

Remember that the engine should be making 100Hp before you turn on a 50 shot (3500rpm).

I wouldn't run more than a 75 shot on a stock rotary and I would wait for 5,000 rpm to engage it (unless it is a two-stage).

These rules where made for piston engines, but I think they should apply to the rotary also.
