why do imports measure boost with "BAR" and we measure boost with "PSI?"?

[ltv1]

There are conversion factors for inches of mercury, mmHg, psig, and kpa. If the people who are working on your rides don't know them, they should. A moron like myself had to learn them in school. 1 Bar=1 atmosphere=760mmHg.

How they apply to cars is very diff. than what I know about

I can assure you, from an engineer's experience (me). Experience works, theory rarley does.

Ain't that the truth!

I think they measure in BAR's so you don't know they are running 29.4 PSI . It's easier to keep your highly elevated boost levels hidden from people this way.

FWIW 1 bar of atmosphere is = to 14.7 PSI.
In theory to double your cars HP, provided the intake and exhaust flow enough, you need to add 14.7 PSI

Take this one step further. If your stock $30,000 + Evo VIII makes 276 bhp on 19PSI, you'd have to run 33.7+ PSI to make 552 bhp:lol:

1997 Cobra FRPP shorties,Bassani X with cats, Vortech @ 8 PSI everything else was stock! 423 RWHP! Figuring 15% driveline loss that is 500+ bhp All this and still well under $30,000
