How high of an RPM do you spray until? I wouldnt want to spray until redline because I would be too afraid of blowing the engine. I was thinking maybe 4500 or 5000 would be the absolute highest you would want to go. Am I right?

 

meh with a window switch i sprayed til approx 6500 rpms never had a issue



tons of people sprayed until then also



with your idea, youd shift to second(rpms would be around 3k) then arm it, spray for 2k rpms, then shut it down mid powerband



dont think youll get the goal your lookin for that way



thats like having a turbo stop building boost at 5k rpms cuz your afraid of blowing the motor

 

Just don't have it flowing and hit fuel cut. That is a bit of a weird window to spray...
