Not when it's available at the track.... And if you're meaning you have to pay per bottle.... It's true, you do.... But how much do you think it costs when something breaks/snaps/decided to put a hole in your wallet....How much do you think it costs to have a blower snout bolt taken off because it either was cross threaded or seized? How much for a new bov cause you want more(or less if you're :gay) power? And I know, I know, you can always upgrade nitrous kits and all that, but not as common as adding pulleys, meth, ect for boosted cars.
Hahaha, nitrous is not the only thing blowing these motors up... Sure if you mess it up, it can, but that's like any FI application. Hell, these engines are popping at just semi bad tuning. If it goes, it goes. Meant it was a part that couldn't handle what was thrown at it in a reasonable manor and needs to be replace with something bigger and better.
