The Taifun Rennmotor team race diesel was a powerful but, rather large and heavy engine for its size. The crank case has the same dimensions as the Rennmotor 3.5 cc. It was the first engine engraved with "Taifun" and "ges. gesch." which means, Typhoon and legally protected. This was not only done to promote the Taifun engines but, also to protect them from being copied. The foundry that manufactured the casting decided to sell the engines too, to increase their profit.
Hans Hoernlein eventually found a new foundry to do the castings. That is one of the reasons for the differences in the casting too.
