bar hopping and PSI/kPa

[Jouko Haapanen]

bar/Pa/PSI conversions from:
http://www.airdive.com.au/Main/Tech_Info/tech_pages/pctable.htm

1 PSI = 0.069 Bar
1 PSI = 0.0069 MPa
1 PSI = 6.895 kPa
1 Bar = 14.5 PSI
1 Bar = 0.10 MPa
1 Bar = 100 kPa
1 KPa = 0.145 PSI
1 KPa = 0.001 MPa
1 KPa = 0.01 Bar
1 MPa = 145.033 PSI
1 MPa = 10 Bar
1 MPa = 1000 kPa
3262.5 PSI = 225 Bar

I think if you are running boost anywhere near the last figure, your
(and your car's) internals will be seriously damaged.
