if you had a set of headers tuned for 7000 revs made, programmed ecu to match, added a larger throttle body / smooth intake, then you'll see 270HP IF the valves are large enough (not sure what the stock diameter is).

that assumes 150F manifold intake temp, .25 psi manifold pressure increase, no thermal efficiency increase, lambda=.8. Just the RPM increase alone, if the ecu has enough play to tune to this RPM, would give you 253. Add everything else and you get your 100HP / L.
