Ford Racing M-9603A-FST Dyno Chart – FRPP vs Stock HP & Torque (93 Octane)

This document is a dynamometer comparison chart titled "M-9603A-FST (93 octane fuel)." It plots power (hp) and torque (lb-ft) against engine RPM from roughly 1600 to 6400 RPM, comparing a stock engine configuration against one equipped with the FRPP (Ford Racing Performance Parts) M-9603A-FST package. Four curves are shown: FRPP torque (solid red), stock torque (solid blue), FRPP horsepower (dashed red), and stock horsepower (dashed blue). The chart shows the FRPP setup producing a substantial midrange torque gain, peaking at approximately 355 lb-ft near 2800 RPM versus the stock peak of roughly 293 lb-ft near 2300 RPM — a gain of about 60-85 lb-ft through the 2500-4500 RPM range. Horsepower curves converge at high RPM, with both configurations reaching roughly 245 hp, though the FRPP configuration reaches that output earlier (around 4500 RPM versus about 5200 RPM stock). Above roughly 5200 RPM the curves are nearly identical. A reader can learn from this chart the RPM ranges where the M-9603A-FST kit provides its performance advantage — primarily low- and mid-RPM torque and earlier peak power on 93 octane fuel — while peak horsepower remains essentially unchanged.
