According to the dyno chart on our engine (or perhaps a similar 2.5L in an Axiom) the SC gives you 45 hp ($70-90 per horse [after installation] !). Given a stocker should run around a 17.2 e.t., a car with 45 more horses should run about 16.0 e.t.

Those are mathematical equations, assuming the same weight, tires, barometric pressure, altitude, etc.
