We're happy to announce the competition guidelines for the 2013 AMSOIL Engine Masters Challenge, the world's most prestigious engine dyno competition, which will take place this fall at the University of Northwestern Ohio (UNOH). We are looking for amateur and professional engine builders to compete in a test of street-savvy engine-building prowess that has the potential to pay $50,000 cash (dependant on use of contingency parts). Competing engines are dyno tested during qualifying on the first week of October with a pair of identically calibrated SuperFlow/DTS Powermark dynamometers, and the top five finalists go head-to-head for the money in a final elimination round the Friday of the weeklong event.
The competition places a premium on usable street power and torque, with scoring being derived from the amount of average horsepower and torque over a 4,000-rpm range (3,000 to 7,000 rpm). To even the playing field between engines of different displacement, the average power and torque within the measured powerband are divided by cubic inches to create the final score. A complete, detailed list of the rules, a description of the payouts, and the entry form can be found on PopularHotRodding.com, but here is a brief overview of the significant competition guidelines for 2013:
