Where the heck are you getting the power to drive this blower? It's got to come from somewhere, and I doubt a turbine in the exhaust could supply it.
Is it a belt driven supercharger? And, even then, that much boost (at sea level) takes an enormous amount of power. You're talking a 340% increase!
You're dead right, southpaw. I know next to nothing about diesels, but the numbers you're quoting just seem way out of line.
I'm happy to have my opinion changed though. Just point me to one of these beasts that can produce those numbers and I'll crawl back under my rock.
