Description
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, PEC are confident they 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….. until now.
If your buying a PEC piston kit, your also buying into our research and development, as well as countless hours of experience and customer feedback on achieving the optimum level of performance from the pistons in your engine.
This piston will give the following C/R’s on all 2.0 Zetec engines assuming unskimmed cylinder heads.
| Gasket | Silver top | Black top (inc. FRS) |
|---|---|---|
| 0.7mm | 7.6:1 | 8.0:1 |
| 1.0mm | 7.5:1 | 7.8:1 |
| 1.3mm | 7.4:1 | 7.7:1 |
| 1.6mm | 7.2:1 | 7.5:1 |
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.
If in doubt, please contact us for advice.
