Perry had been his own guinea pig and has melted several pistons over time to get where he is. I wouldn't want Nitrous for my own car, but being fascinated by the engineering I respect the skills of any home mechanic who can make it work. Nitrous is more common on road cars than you may think, and it's a mod chosen by some linked to kickdown on auto boxes for extra power when it matters. And it's not just young nutters who do this either!!!
