^ actually, I bet it would be incredibly easy to find out for a common size...lets say:
1996-2000 b16 engine, JRSC, and a cost-wise equal garrett kit...stock except for the Forced induction...
We'll measure efficiency by final out put to the wheels in terms of HP & TQ...which ever form ( SC/turbo ) makes more on a stock engine...
I want to know whp, & wtq and boost pressure ( lbs )...I'll post up what I find w/links...LMK what you find...post back here by 10pm central with what you find...
By "free" HP, all that is meant is the source of energy used to run your preference of compressor...
-turbo uses what's already there...( Exhaust gas pulses )
-sc uses pulleys that detract from crank power...( to run rotors on JRSC )
