And just for the Record: I wasn't encouraging anyone to fill Scuba tanks with N2 but merely use the standard filtered and dry air that any Diving Centers Compressor system delivers as a cheaper substitute than the N2 for the discussed Track-day usage. I apologize if that could be misunderstood. Secondly as correctly mentioned extreme precautions should be taken when using a source of high pressure. If you live close to an Airstrip it might be worth to pay them a visit. The Engineers there may be able to help you with some N2 if you insist ;-)
