Fantastic strength and light weight !

    The following new items, made from titanium, were introduced by PAECO in 1999. Titanium is a unique metal that is approximately twice as strong as steel, but only one half the weight. Since a tremendous amount of HP is consumed in an engine by simply moving parts up and down at high RPM, titanium can provide both more power and greater reliability. Parts can be made at twice the strength and half the weight, OR at the same strength and 1/4th the weight. If you are a serious racer, you should consider titanium for your engine.
