Nitrous/NHRA legality help needed

I am installing a nitrous kit on my 2000 SS w/A4 transmission.

So far I have:
Stage 1 NX nitrous kit
Blowdown tube
bottle warmer
purge kit
window switch
fuel pressure safety switch
bottle mounted nitrous pressure gauge

I plan to mount bottle between rear seat cushions.

I cannot find any info about what I will have to do to ensure the setup is completely NHRA legal. I know I need the blowdown tube, but what else do I have to have, have to do, or make sure of?

Thanks in advance.

I'm pretty sure the blowdown tube is all that is needed. well that and a NHRA approved fire jacket with the right SFI rating for you

Yep, fire jacket and an ET of 11.50 or slower (if you don'thave a rollbar).

I know that any fuel tanks need to be separated from the driver by a firewall. Any requirements of the sort for NO2?

The only thing for spray is the the bottle has to be secured, and the blowdown tube must vent outside the passenger compartment.

Also, IHRA requires the use of gloves while running N2O

So...blowdown tube, and fire jacket, regardless of ET, correct?

In all honesty, the nitrous will be used mainly off track, but will be used at least once at my local NHRA track to make this new Shelby GT500 owner/friend of mine STFU....My car runs 11.60's-11.70's naturally aspirated (he's been 11.50's so far), so I already know a rollbar (amongst other things) will be needed to run what the car "should" run, more than one pass.

Thanks for the info.
