Hi. Compression 14.0:1\u003c\/p\u003e \u003cp\u003eExtreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mec 56-W4961.WI.RE\" Compression Ratio - Actual:  14.5:1\u003cbr\u003e Features. -R\u0026amp;D developed. -Asymmetric skirt design. -Precision fit ring. -100% billet machined. -High compression. -Dome design.\u003c\/p\u003e \u003cp\u003eimpact and fatigue.
