Really...
The turbo has a boost pressure above 1 bar or 14.7 PSI ?

WASTEGATE OPENS AT .9 BAR

I found these numbers on the turbo charger. Boost Pressure/Wastegate Pressure: .9 bar (13.05 psi). I take it this is "PSIG" boost which would then be 13.05 psi or 27.75 absolute? If that is the case the I stand corrected but I'm not convinced my friend. Read the boost gauge on a car when it is not running. It reads 1 bar.

Q. How else does a turbocharged engine make 40-50% more power?

A. Well it is because it supplies the combustion chamber with more air for the fuel/air detonation. My post was not that far off when I said "
as valves open and close faster at higher RPM's there is not enough time for all the air to fill the vacuum in the cylinder to make 14.7 PSI, a turbo or supercharger can help to balance this out, in an over booted engine it can pump in more then 14.7 PSI."

It's all relative the air pressure running through the turbos vains on each side of the engine will still move and pressurize air. It just is lower pressure then that of what is outside. You can still feel the air blowing on a mountaintop; it just takes a higher speed to feel the same as on the ground.


The 14.7 psi is absolute pressures so yes a flat tire is 1 bar and an inflated tire is bar + 32 psi or 46.7 psi absolute pressure. Take a flat tire with no leaks around the bead up 20,000 agl and see what happens. Of course it will be flat when you hit the run way again.

Try this on for size. Fill an empty paint thinner can with 1/4 inch of water heat it until the water is seaming out the opening. You have now displaced the air. put the cap back on and watch what happens when the water condenses back to liquid and leaves a vacuum in it's place. The air pressure around it crushes the can.

When they say the turbo is .9 bar I take it as meaning .9 Bar unless it means .9 Bar of boost above 1 bar. I may be wrong though, just prove it, Let keep this a friendly debate. Typing all caps is sometimes considered rude.
