Just installed my Fidanza Aluminum Flywheel, Center Force DF Clutch and Ford Racing Aluminum Drive Shaft. Dyno'd the car before the install with the stock plenum still on made 259rwhp and 298rwtq. Last time I dyno'd the car I made 270rwhp/309rwtq with the aftermarket plenum. Going to break-in for 500 miles then dyno to see if I gained anything.
