General question about FI

axeman71

Before my Z I owned 2 Miatas ('99 and '06) and I toyed with the idea of a FI system for both though I never pulled the trigger. In general on those cars the FI systems, either supercharger or turbo, made around 6-8psi boost with upgrade options to get you into the 10-12psi range. That was the realistic max unless you wanted to start changing out large portions of your engine hardware to handle the strain. A quick look at a couple of systems for the Z seem to generally be in the same boost range.

I just finished reading an article on Inside Line about the new Sonata 2.0 Turbo. It makes 17psi boost. That seems ridiculously high to me. Then I remembered the turbo version Solstice had something like 18psi boost (I can't remember exactly). Why can these cars handle so much boost? I realize they are built from the factory as turbos but still that is a large difference in boost.
