DUX BIG BLOCK MONSTER 156CI AND 225CI

The D?x Big BlockTM V-twin street engine was conceived several years ago by Michael D?x (motorcycle parts distributor in Hamburg, Germany

D?x commissioned Randy Torgeson (Hyperformance) to create and develop the components for the massive bore/short stroke powerplant. Randy applied his many years of experience building enormous fuel and gas racing engines to resolve the design and engineering challenge of the giant ductile iron Big JugsTM, CNC billet MegaHeadsTM and the complex valve train geometry and related parts. Preliminary prototype engines were assembled using cast aluminum cases in a 144" version. The final version uses gorgeous Ray Keck CNC billet cases.

The result is a beautiful blend of German inspiration and All-American craftsmanship, ingenuity and simplicity. The power potential of this "oversquare" design is still being explored, but recent dyno testing of a prototype Big BlockTM with a moderate duration cam yielded smooth power and awesome torque.
