All You Need and Wanted to Know About WPC

An unusual property of WPC is that it is sometimes difficult to see horsepower gains directly as dyno test results. WPC, in addition to helping with power production also helps improve dynamic response, something that is difficult to measure on a dyno. This is why a WPC treated car may turn consistently faster lap times even though it is difficult to prove a power gain on a dyno.

WPC advantages

• Greatly improves fatigue strength and stress corrosion fracture resistance
•  Improves surface hardness and surface finish for increased strength, reduced friction and improved wear resistance
• Increases in horsepower and engine transient response are seen from friction reduction and improved ring seal.
• Micro dimpled surface will not harm and works well on finely finished machined areas such as seal contact areas, bearing bores, bearing seating surfaces, crankshaft fillets and other delicate areas.
• Does not distort close tolerance parts
• Does not damage soft or fragile parts
• Not easily visible to the naked eye
• Can take the place of several different processes to save time and money, for instance shot-peening, then coating
• Is compatible to and enhances the advantages of other processes such as Ion Nitriding, Cyro Treatment, REM, Mikronite, DLC and other high performance post treatments
• Treated assemblies run cooler
• Can double the service life of a racing or high performance street engine
• No significant drawbacks that we can think of!

WPC Disadvantages

• It’s not free!
• The process is only available in Southern California; parts to be treated must be shipped.  However WPC has good service and fast turnaround.
• Parts need to be disassembled and cleaned thoroughly before and after treatment
• Process is secret so you just have to trust them!

A real life example of WPC at work

Compass 360, a leading Koni Grand Am Cup team ran two Acura TSX’s in the ST class. Both cars were equally prepared with one difference; one car used the WPC process extensively in its engine build. Billy Johnson, one of Compass 360 drivers, relayed to us that the WPC treated car was consistently faster all season.
