It's the one that's concealed inside the air cleaner assembly, and disperses from above the carb. Is it safe? I like the idea of a hidden system. Just playing with ideas at this point.

It would be on my 451. KB forged pistons, Mahle Plasma-moly rings gapped for nitrous. H-beam rods, forged RB crank, studded mains, cleavite bearings.

Monte, you around? Tell me what you know...

Nobody??

no top shot but I love my nos plate system, top shot does basicly the same thing as a plate but is hidden a little better, plus the hp level isnt as much, if you go with a plate system with some work you can hide it pretty well where most people will never see it. heres a pic of my car you can barely see the steel line in the front of the air cleaner

I have the part of the kit that goes in the air cleaner but sadly have never used it.If you have any interest I will dig it up and we can talk.
I see it as a good idea when you have no room between the air cleaner and the hood for even the smallest plate under the carb(like myself).
Don't think I will be trying it anytime soon though.

It would be interesting to hear Monte's take on it.I wonder if it matters the nitrous coming in from on top of the fuel versus inderneath it on a plate?Distribution or atomization problems??
