We are pleased to announce that the 2007 Engine Masters Challenge will be held at the University of Northwestern Ohio's High Performance Department compound. This state-of-the-art facility houses two DTS engine dynos (as well as two chassis dynos) and promises to provide an ideal setting for the Challenge. Assisting with the competition this year will be the crew from UNO's High Performance Department, including both instructors and their top students.
New Rules For 2007!
The 2007 Engine Masters Challenge will challenge builders' imaginations like never before. In a major departure from previous competitions, where the specified cubic-inch displacement has defined the format, any stock production passenger car displacement with more than 300 cubic inches can be built this year. Competitors will select any OEM production displacement for the type of engine being built, and will be required to maintain the OEM stroke (+/- 0.015), and the OEM bore (no larger than +0.035-inch). For example, those wishing to build a small-block Chevrolet can select from OEM displacements of 302, 305, 307, 327, 350, or 400.
As in previous years, scoring will be for average horsepower and torque that is more than the specified rpm range of 2,500-6,500 rpm; however, the score will be divided by the cubic inches claimed by the engine builder. If the engine techs bigger than the claimed displacement, it will be disqualified during teardown. The engine with the best average torque and horsepower per cubic inch will be the winner. The engines will also be required to run on the supplied 91 octane pump gas, and are limited to 10.5:1 compression.
