We recently carried out some upgrades to Davids rally 924S. This consisted of a modified camshaft and an increase in compression. Along with our AugTronic ECU and a custom live re-map on the rollers this high mileage engine made 182 horsepower at the flywheel. The peak wheel torque was 160 ft lbs @ 4300 rpm, this gives a peak flywheel torque figure of 180 ft lbs. The standard 924S runs a slightly lower compression than the 944 and as standard only makes around 150 hp in our experience.
