On childish, or juvenile, fantasies the Subaru could have built in a much shorter time, but one likes to look forward to each improvement in performance.
As we all know, the half-life of a performance increase is around six months, when another increase is needed.
Of course, performance increases include handling and braking as well as acceleration.
Right now the juvvie urge for more of the latter is building, and with the advent of warmer weather it will be a 1.5 bar chip and dialing the boost up to 17. Should be producing around 250 wheel torque.

--for around six months.
