How much does it cost to get a Nitrous bottle filled?

And where is a good place to get it? Welding Supply, gas Supply house?

most any local speed shop can hook you up, on average your going to spend from 30-45$ to fill a 10 lb bottle.

Call around to any local speed shops. I doubt you'll find any in a welding shop. Gas supply, maybe if they're set up as a filling station. Somebody needs to have a filling station to fill the bottle. Automotive NOS is different from medical NOS and I doubt you would be able to buy medical NOS. Automotive NOS has a sulfer additive to prevent misuse. ie: it stinks.

Last time I filled my bottle in my truck I was paying around $5.50/pound Canadian. With tax it was close to $60 Canadian to fill a 10 pound bottle. My truck gets 7-10 passes on a bottle.

nos has alist of places on their site where you can get em filled according to where you live...then just call em all and see whos the cheapest........very simple http://www.nosnitrous.com/HiOctn/Pro...S/NOSlist.html
