After years of market research and actual product testing in conjunction with several well respected tuning companies, PEC at last launches a new breed of piston on too the European market. One of the things missing from the European aftermarket industry, is a mass produced piston range that is engineered for the end users needs. Using the last decade's of experience, we here at PEC are confident we have developed a range of pistons to suit almost every possible need.
Why are PEC pistons so good? Well the answer is simple. Most mass market piston manufacturers will rely on online data and a single customer's feedback when creating a piston, often without taking into account things like the average age of an engine, the correct cylinder head chamber volume, the correct gasket thickness. All this can be calculated, but it is never 100% correct..... PEC rods are designed to withstand roughly 225hp per cylinder (typically 900hp on most 4cyl engines) and on the ARP 2000 series 3/8 bolts normally provided & have an 8,500 RPM safe operating limit (engine specific).In some cases, we recommend using the ARP custom age bolts available from us. This increases the hp threshold to 250hp per cylinder and raises the RPM limit to 9,000 however as every engine is different, these numbers are not guaranteed for every configuration. Prolonged high RPM's for drifting, or sudden bursts of torque for drag racing (as two examples) will warrant the use of the custom age bolts to help retain the clamping force between the big end cap and the connecting rod. H-Beam and I-Beam section connecting rods are forged from AISI 4340 (En24) steel. Heat treated to HRC 35-38 and then shot peened for a higher fatigue strength. Small ends are bushed for a fully floating pin and big ends are fitted with high quality ARP fasteners with different specification bolts available depending on the level of performance required. Manufactured from forgings originally produced in Sweden, PEC connecting rods have offered engine builders and tuners a cost efficient and yet high performing solution to a wide variety engine building problems.
