1. You can't fairly and accurately compare hp/l of turbo charged engines to non-turbo engines, finest examples or not! Of course any half decent turbocharged engine will have better hp/l numbers than almost any NA engine. Would it be an accurate comparison to compare an engine running nitrous to one that wasn't and conclude that the first was a more efficient design?

2. We're not talking about a 13hp difference. We're talking about a 13 hp PER LITER difference, it's not the same thing.

3.
a) Go to the link I posted in my last post. In that link a turbo charged GT2 is described which has undergone many of the same changes that are performed on tuned Saab engines and the result looks to be an estimated 950 hp from 3.6 liters. In that link you will see the parts listed that were changed and you can go ahead and make your own list for yourself.
b) Stop trying to compare the specific output of a non-turbo charged GT3 engine to a turbocharged Saab engine--it's nonsense. If you read a magazine article where the author made a direct specific-output comparison between a turbo and non-turbo engine you were reading a great example of irresponsible journalism.

Provided an engine design is inherently strong enough, ALL fairly efficient modern engines with sufficient flow modifications manufacutred by ANY company (Porsche or otherwise) can approach very similar specific output numbers--which for street use, will ultimately be limited by the type/octane of the fuel available. There's nothing magical or unknown in that statement.
