Speed Pro Forged Pistons for Fords set the standardfor the performance industry, with material and designsuperiority that has been provenin every form of racing. Theforging process hasinherent advantagesin terms of density,ultimate strengthand durability.Forging eliminatesporosity in themetal, improvesductility, and willallow the piston torun cooler than acomparable cast unit. POWERFORGEDpistons start from a “nearnet shape” forging, with adesirable horizontal grain flow andtightly controlled head thickness. This minimizes pistonweight without compromising strength. These pistons arebetter able to withstand the high cylinder pressures andskirt loads imposed by racing use, and are more likely tosurvive limited detonation and valve piston contact whichmay occur during a race. If your vehicle is to be used forendurance racing, faster classes of drag racing, or extremeduty street performance, you should probably select aforged piston. Engines with very high compression ratios(11:1 and over), high boost superchargers, nitrous oxide, orwhich operate under conditions approaching detonation willbenefit from the powerforged piston's characteristics.
