Schnitz Racing/MPS are well known - this might be worth considering.
The Spyder Nitrous Spray System uses 4 individual NOS flare jets for exact distribution of nitrous to each cylinder.This eliminates problems with uneven distribution associated with larger nitrous shots in dry nitrous systems
Spyder Nitrous comes with whatever jets you specify. If you do not specify, it automatically comes with #16 jets
The nitrous enters the air box through a 4 bulkhead fitting on the bottom rear of the air box. The bulkhead fitting inside the air box is connected to the distribution block via a 4 line. From the distribution block the nitrous passes through the 4 individual jets and through the stainless steel tubes into the appropriate port
The Spyder Nitrous System is capable of producing 200 horsepower when used with the proper components
The Spyder Nitrous Spray System can be easily adapted to fit most fuel injected sport bikes
