A turboprop powered aircraft is not the same as one with a turbocharged piston engine. A turboprop is a turbojet or turbofan engine which has its compressor section driving a propeller instead of a fan disk.

You're right in that the wastegate is usually wide open at sea level, but that depends on the application and conditions/desired performance. There are many turbocharged aviation piston engines that boost at low altitudes.

Not a turboprop as in the turbine driven propeller air craft. I was talking about the turbo charged piston plane, that was a typo, but the remainder of the statement was factually correct in that most turbocharged piston planes were only turbocharged to normalize performance at altitude rather than increase performance on the ground like a car.

Just trying to give examples of automotive engines.

Yes, most are,however there are many designed to make use of forced induction at low altitudes. Whether cruising as 15,000ft or at sea level reliability is more important than it is in a car was my point. So saying FI is not safe just isn't correct

The obx/fswerks header is catless, probably some of the others as well.

Other than a stock turboed car I've never driven a reliable turboed car. I drive a reliable car on nitrous.

Forced induction is forced induction no matter what you need to have your fuel tables correct.

I fail to see how nitrous is any safer than those two other options.
Hoe reliable are these cars? Have you ever owned one?

Then something was wrong with those turboed cars. I've known plenty of people with reliable turbo cars. Saying you haven't seen a reliable turbo car doesn't mean they don't exist or that nitrous Is safer for your car.

No not personally. But I know people who own some of these vehicles and drive them a lot and they are reliable. They are factory vehicles designed to be driven daily. As long as they are properly maintained they will work. I'm not trying to say nitrous can't be reliable either though. But saying FI isn't reliable would be false.
