How do you get the 20 hp per lb of boost?
there is ~15 psi at sea level for 180 hp.
This puts the na motor at 12hp / lb.
The sc adds heat to the mix, so timing has to be retarded and premium burned..
Keep in mind, it takes hp to compress that much air / flow rate..
~5hp / lb isn't that bad for a 3.3 after the losses.
The heads are not designed for high hp, not smooth enough flow. The cams are designed more for torque then HP. Get a 5.0 mustang with other goodies, and you may make 30hp/lb..
