How does 1000ft-lb of tq at 3K rpm sound?

Granted it had a bit of C16 in it, put 91 in there and get 850 atleast out of it.

Here is a 370 with a relatively innefficient t-76, almost 800ft-lbs at 3500

As you can see turbos "turn-on" well before your 4500rpm window. There are TONS of centri graphs which are going to have a VERY strong correlation to turbo graphs. A properly sized turbo will be more efficient and make more power(throught out the range) then any blower IMO. The only time I would think about a blower is if I did alot of towing and needed super low end grunt, a turbo wont be able to match that for the most part unless you go with a undersized turbo that will reduce top end power greatly.

And here is a nitrous fed lawnmower just for the hell of it that I found while I was searching
