JPM Billet Cylinder

Phone for price

JPM billet cylinder is made from cast iron with a very solide structure.  The material is commonly used for hydraulic cylinders with pressures that never is experienced in a combustion engine. The choise of material prevents the cylinder to expand too much and therefor the valve lash is still controlable when engine is hot.  A common problem when stepping up to 94mm bore is big crank case  breathing. The crank case breathing is because of a not circular  cylinder, too deep releases i for the head studs makes the cylinder like a square when torqued. Too big difference in material thickness causes the cylinder to deform when torqued.  

PM billet cylinder has a very even thickness and therefor it is perfectly round when torqued to  specification. The OD of cylinder at top is made bigger(102mm 4.015")  than std(101.1mm 3.98").
