- I am not familiar with superchargers. But that 3000psi sure made me nervous. It
- is about the pressure of those bottled gases that I deal everyday in my lab.
- Something with this level of pressure should be handled very carefully. I
- believe this tank will kill the driver like a bomb if the car crashes. Don't
- forget the pressure inside the cyclinder is just about 200psi and four of them
- will be enough to drive a several thousand pound car up to 85 mph.
