#1 I am not sure I would take a motor and run it at 12,000 RPM for any period of time. Certainly a motor that may have had multiple owners and variable maintenance. I have missed shifts many time and I cringe to think how fast the motor may have gone. Considering how many times it has happened to me I gotta hand it to the motor designers.
Now lets' clear something up. I am from NY and I grew up among other Italian Americans my whole life. We use terms such as Guinea, Wop, etc among ourselves the same way Blacks use the N word. It is allowable. If an outsider uses it, or makes fun of our women, the more hard core among us would probably jump someone, and in neighborhood like Arthur Ave, Morris Park, Bensonhurst, and others you watch your ass.
There is a TV show called Jersey Shore, they are the worst of us, and we would call them Wops which would be the same as White Trash. They are Gavones which means peasants.
I have 30 cousins and none of us speak the language. We have Teachers, Doctors, Dentists, Accountants, Financial types and Musicians. No more day laborers or wiseguys.
NY has a culture and we have cultural rules, and it works for us since we all know the rules. If you forget the rules, someone will remind you.
