If you had a 'supercharger' (belt driven) instead of a turbocharger, you
would agree that the supercharger is sucking power from the engine to do it's
job. Friend of mine has one, and estimates that it takes about 30
horsepower to run the supercharger. If you were driving this supercharger
, and keeping the manifold pressure to 30", then you would be getting *less*
power from the engine-supercharger combination than a NA engine.
The same may be happening with your turbocharger. It is sucking power
by increasing exhaust backpressure, but you are restricting the manifold
pressure that needs to be higher in order to generate more power. You have to
generate your net power *plus* the work the TC is doing.
Does this make any sense to you?

Bill, Great
way of explaining it :-) As you'll see in the post that crossed paths just
now, yes, it does make sense. The real question is just how much power am
I losing to the turbo.
Thanks,
Rusty
