140ps for an FEAP cammed engine. They are badly choked and really wake up with FE5A cams in them (150ps IIRC). A small turbo or medium supercharger (super inefficient) will get your 200hp pretty easily. 6psi from a turbo or 12 from a super charger will do it. Being difficult will cost you fuel efficiency, engine-stress, and peak output, but at least it'll be linear and instant, right?
