A few questions about nitrous use on a daily driver. 1) Is there a "shelf-life" to bottles? Like do I have to use say, a 10-lb bottle in a week or something gets messed up? 2) I've heard that nitrous doesn't create so much pressure as it does heat, therefore one can run high compression and nitrous at the same time, unlike ***chargers. So say on the street the max compression I can get on pump gas is 11:1, can I put a 200-shot on top of that and still run pump gas, or do I need to lower compression slightly?
