A '98 stock [4.6L 2V] pump will deliver 150 L/h (39.7 gph), same as the '98 Cobra pump (according to the shop manual). If you do not plan to add a supercharger or nitrous, the extra flow provided by the FRPP pump is really not necessary. Until you near the magic 300 rwhp mark, I suggest replacing the sick pump with a stock pump.
