All custom built at defined autoworks. The worlds first ever 4-rotor to use a 5th main bearing, in the center. This along with other internal modifications allow for 12,000 rpm capacity. <br /><br />www.definedautoworks.com <br /><br />614-592-7991 <br /><br />We specialize in all rotary engine types and build to the highest standard.
