SHOW NEWS: Reducing cast iron block fractures

Internal fracturing from cast iron engine blocks is a problem for road racing, drift cars and drag race motors. The weak, poured cast iron cylinder wall often can’t cope with the boost and compression required by competitive motorsport but ProCross ProCool Cylinder Liner kits from LA Sleeve replace the cast iron cylinder wall in these engines with a centrifugally spun-cast ductile iron Amphibian wet/dry sleeve. The Moly2000 ductile iron has 113,000-psi tensile strength and proves a worthy fix to fracturing cast iron cylinder walls, and provides an allowance for even greater boost levels and cylinder compressions while allowing for larger bore piston displacements and not sacrificing the block’s cooling capacity.

LA Sleeve can be found at the 2017 PMW Expo, at Booth 7038
