Hell I am no car genius by any means lol.
Spraying with a 3gph nozzle using 20% nitromethane=.6gph. Without being exact and breaking out the calculator the 3gph spray is about 10.5% of the total volume of fuel being sprayed (using a rough 1800cc spray volume total for the stock injectors) and .6gph would equal around 32cc which would be around 1.7% of the total volume of fuel going to the motor so spraying 1.7% nitromethane would be safe since only .28% of the total fuel volume per cyl would be nitromethane. (Rough estimate but relatively close).
BUT if you did go crazy with it and sprayed too much or if the nitro/meth mix would seperate and you sprayed a pure shot of the nitro then it could be trouble. You have to be VERY careful how you mix that stuff, it wants to seperate if you do not get the percentages right. Too much or too little nitro in the methanol and it will seperate to the bottom of the tank and you risk spraying 100% nitromethane in your intake.
Edit:
Oh, and when using nitromethane to spray it does the opposite of the methanol. It makes your car run a little leaner. If you spray wather/meth mix you richen up by about .6 a/f ratio but if you add nitro to the mix it will actually lean out a little.
