Twin Turbo 383 questions

CUUDAK said
I believe this to be true in a Supercharged engine since the engine produces the power to move the blower from the crankshaft. However I believe that this is incorrect in the Turbo engine since there is "No" power being taken to move the Turbo. I personally seen a smallblock Chivy that produced a bit over 400hp alone. After the 2 turbo's were installed it produced well over 900hp @ 20lbs boost. This proven on a dyno!

O' a stock 383 produces 335 hp stock. This was said to be with all assys. and at the tailshaft of the trans.. Furds and Chivy's were rated at the flywheel. I have seen the 383/496 produce nearly 600hp.

The blower certainly takes a couple hp..
In the end however it simply is a matter of fact that an engine is an airpump. The power its going to make is simply a factor of how much air and fuel can get stuffed inside. That really doesnt change depending on what method of forced induction is used. ( blower, turbo, N02 )

Turbos do steel hp as well.. There is no free lunch and the huge restriction in exhuast flow will cost something. I dont know enough to tell you what those numbers look like or how they compare to a blower.. Anyone else know ?
