Hold off on the spray idea until you have the N/A motor tuneup all sorted out.
The fuel curve must be dead on or you will hurt parts.
The mechanical pump (alone) is a mistake$$$ with nitrous.
Again been right where you are at. Been playing with small and big nitrous and going way to fast, for some 30 years on cars like yours and mine . And some silly powerfull racey stuff too.
The Hyd roller cam (limited rpm capability) is a point too with nitrous.
You do not want engine fuel in consistant -leanout or valve float-hyd lifter pump up with N2O. $$$$
Bad things happen fast on nitrous.$$$
You are not there yet.

I totally agree with this...you need to really finish sorting out all the little things naturally aspirated first.

Don't even think about nitrous without an electric fuel pump.

"Bad things happen fast on nitrous" is an understatement for those who don't have all their ducks in a row first. It will happen faster than you can even begin to react to save the engine...literally "the blink of an eye".... and the engine is hurt.

Along with the fuel curve, the ignition timing has to be corrected for the nitrous use.
