2009 AMA national and FIM world land speed record at Bonneville salt flats

It has been great success with WPC treated moving parts in engine and transmission in past years. Last year I profound anther surprising benefits of WPC.

A week of land speed racing at the Bonneville, the engine suffered cylinder head bolts failures multiple times and time was running out. My last resort was the WPC treated OEM head bolts. After WPC treated bolts installed, engine stayed together and set two AMA national records and a FIM world record in the end. Simply amazing!
Thanks WPC.
