Being a former Terminator owner I can attest that the 4v motor they put in the 03/04 Cobra was not only underrated from the factory, but was/is one of the easiest to get power out of with simple bolt-ons. Car was rated at 390/390 from the factory and I added a CAI, full exhaust (incl catted X-pipe) and a tune and put down 425RWHP with a rich & safe tune. Added a 2.93 upper & returned later down the road and was putting down 465 RWHP. Total $$ invested in mods & tuning was under $1500!
