DUEL was founded in 1993, our main activities existed of building and maintaining formula cars and their engines. One of our specialities was, besides modifying the engine itself, developing our own camshafts and exhaust systems. Along those years we came in contact with several Porsche drivers, who asked us to modify their engine and chassis. Soon it became clear to us that Porsche is a car with great potential and with an amazing racing history. This is why Porsche became our core business and the reason we now prepare mainly early 911's and Porsche prototypes for race and rally purpose.
