That is my point. There does not appear to be any reason for anyone to
ever buy a turbo norm system. The engine runs just as hot/hard, etc at
altitude with a turbo norm vs. a regular turbo. The turbo norm
companies try to trick people into thinking that putting a turbo norm
on your engine will not wear your engine any more than normal asp
because you never get over 30". However, the argument appears to be
worthless, in truth a turbo norm wears out your engine just as fast as
a regular turbo.

Not true, if the engine is cooled with adequite airflow. If you have an
instalation that is marginal at cooling a non turbo instalation at altitude,
and you put a turbo norm engine in it, yes, it will overheat and wear out.
Put enough air across it, and it will stay cool at 65%. There are all kinds
of flying examples to support this.

What is the difference at flying a well cooled turbo norm engine at 12,000ft
at 65%, and at flying it at sea level and 65%, if you keep it cool ?
