[quote name='cymfc3s' date='May 5 2005, 10:29 PM']The 2 biggest reasons for having a turbo-charged engine in an airplane:
1. High altitude engine effeciency.
2. Cabin Pressurization. Air is bled off the turbo and into the cabin so you can fly at high altitude and not have to be on the o2 bottle.
I used to work on Piper Malibu Mirages back when they first came out. They sent all the techs to Garret school.

Except the regs specifically state you must be on the bottle over 12.5 to 14k for more than 30 minutes or on it at all times above 14k. Passengers of course can just fall asleep if they wish or perhaps utilize the turbo.

What are they normally made out of? Steel? Cf can be stronger than steel, and since it's lighter centrifugal forces would be a lot less too.

[quote name='mazdaspeed7' date='May 6 2005, 01:24 AM']A turbo with a wastegate sprung at 10 psi will make 10 psi at sea level, and 20 psi at 20,000 feet.

I just noticed a typo in my original post. It should be: A turbo with a wastegate sprung at 10 psi will make 10 psi at sea level, and 10 psi at 20,000 feet.
Anyways, compressor maps are always at a standard pressure. Compressor maps tell you how the turbo performs under standard conditions. In reality, the conditions vary greatly, and it does affect the turbo performance. But regardless, the wastegate is actuated off manifold pressure, not atmospheric pressure.
