Established in the year 2000 and with more than 30 years of racing experience, MCR Engine Development has quickly become one of the top race engine builders in the USA. With the goal to change the kart racing industry with honesty and integrity, Matt and Clay Dewing (the twins) have done just that and continue to work towards that goal today.

Matt and Clay believe in perfection in everything they do, and that is key in machine work and race engine design. Clean, professional and without compromise is how they design and develop their engines as well as keeping this mentality when dealing with their customers and vendors.

If you want the best results, and wish to work with a highly qualified team with professional experience and equipment then MCR Engine Development should be your first and only choice for your engine preparation.
