NOS, is this possible

I am not looking to go out with a bang, but an extra 30 hp or even 50 would be nice if there is a way to do this up stream of my 390 holley in my breather tube, I am taking a risk of showing my ignorance in this thread :D But it won't be the first time. I have plenty of fuel I believe entering my little 170/ and I know the bottom end of these /6 will handle the added power, so with all this said I was wondering if we have any NOS experts here that can help me see this threw and make a few passes at our 1/8 mile fun track, I can run a 11.30 now and I drive my 66 plymouth every day and would like to enjoy a passable 11.0 class race now and then, I have never ever had any experience with NOS but I have been looking at some tec help on u yuutuub It would be nice to have a small bottle and dry spray it in the picture below....... or am I just fooling myself :sign3:, and yes I would like to hide it and remove it :glasses7:

Still wondering if I should hit the post button :banghead:
Here is the system I was watching here VVVVV
