What legaly has to be visable on a nitrous bottle for use at the track? Im stripping mine down and havin a buddy airbrush it for me and I got to thinking if the non-flamable and oxidizer symbols have to be on em or if it has to say nitrous oxide.

 

i sanded mine down and polished the aluminum, so there is nothing visible. i havn't had a problem, but i don't have to go through a real tech. just a quick check. as long as i have a blowdown, they dont care about the rest

 

Ya up here they are strict , then again I understand its for my safety. I plan on running at ZMax soon, last time I was there for a TnT the tech said it has to be by the NHRA rulebook no exceptions. Thanks for your info

 

Anyone else with info??

 

The numbers stamped around the top on the nitrous bottle tells you:
-weight of contents
-who it is made by
-serial number
-date is made
