A large plenum full of nitrous is a bad thing IF you get a backfire.

is the problem plenum full of nitrous or plenum full of fuel?

how about nitrous fed through the plenum and extra fuel dialed in through the injectors via the tune?

For a small shot of 100hp or under you will be fine 99% of the time, anything over that on a Superram you need to go direct port. Which can be done directly into the short runner sections of the Superram. Just be aware there is an inherent risk of a nitrous backfire no matter what way you decide on.

Mine is behind a 58mm throttle body, and the plate holes are the same size or slightly larger the the bores in the throttle body.

I run a 150 shot TNT kit 58 mm tb plate style through a LPE 58 mm tb on my super ram.

I have had one backfire which totally killed my MAF, but that was before I installed a purge kit. I have yet to try the nitrous since the purge kit. I need another fuel solenoid cuz fuel was left in the lines and went bad and killed the O ring apparently.

It was a loud freaking bang , err...kind of pop I guess. I immediately looked in rear view mirror as I lifted off the gas to see a huge plume of black smoke. Checked gauges, nothing real bad, but on the comeback lane noticed Service Engine Soon light. Car ran kinda crappy for the remainder of the day. Yes, I still ran it a few more times
