*On a Focus RS engine, this will give the factory Compression ratio of 8.5:1

If used to convert a Focus ST engine, this will lower the compression ratio from the factory 9.0:1 to 8.5:1*

 

 

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 reccomend 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.
