Those familiar with the Engine Masters Challenge are aware that the competition format is changed on a regular basis. This ensures a fresh perspective on the engine-building approach and presents the competition builders with new challenges in achieving the ultimate engine combination within the rules. For the last two years of competition, we incorporated some significant changes to the program, both in the realm of technical engine specifications and in the test procedure. The most dramatic change was a move back to a single division format for last year's competition, with an emphasis on street performance. Our competitors took these basic constraints and pulled off some amazing combinations. For 2014, we have revised the program to focus on traditional two-valve V-8 engines. Here is a brief rundown on what to expect.

The following presents an overview of some of the key rules changes and some insight about the reasoning behind them. Bear in mind that this is to serve only as an overview for informational purposes and that the official rules are subject to modification through the course of the year. For a comprehensive look at the exact requirements for an official entry into the 2014 AMSOIL Engine Masters Challenge event, consult the official rules found on our website, Remember that the competition is open to anyone who meets the broad eligibility requirements—and that might include you. If you think you have what it takes to build the hottest street engine in the country, don't hesitate to send in an entry as outlined in the official rules by our February 15, 2014 deadline.

Back to the Streets

As with last year's event, we will be returning with a single class of competition as our format for 2014. Many of the engine specifications have been changed in the technical rules section, as has the operational procedure on the dyno. The competition will be scored in a new way, taking an aggregate score based on average horsepower and torque over the entire scored operating rpm range and then adding in the peak power and torque per cubic inch in determining the final score. The effect of this change in the scoring system is to place a higher weight on peak horsepower and torque numbers. This will reduce the influence on the score of engine performance at very low rpm.

The rules for 2014 are a refinement of those of last year's street performance style rules, with key changes in the specifications, rpm range, and allowable hardware. What is allowed is detailed in the "Official Technical Rules" found at Here are some of the highlights of the changes for 2014 compared to 2013's rules.

Keep in mind that these highlights are for general informational purposes only. The official rules cover the various restrictions and requirements for competition in detail, and the rules are subject to change and clarification.

In studying the official rules, you might notice the street division technical rules are similar to those of the AMSOIL Engine Masters Challenge last year, with a few changes and tweaks. The objective here is to present engines that more closely resemble the kinds of engines that power true street machines, while opening up some of the specifications to the hotter end of the performance scale. At the same time, we tightened up some of the rules to more closely reflect real-world parts combinations. Significant changes have been made to the scoring system and the operational procedure during competition.

Show Me the Money

For the 2013 Engine Masters Challenge, the contingency payout format has been revised to bring back what is one of the richest purses for this type of competition anywhere. We found the fat payoff added considerably to the heat of the competition and met with unprecedented sponsorship support. While not quite a winner-takes-all format, the payout has been scaled to richly reward the 2014 AMSOIL Engine Masters Champion.

1st Place - $3,500 per contingency
2nd Place - $400 per contingency
3rd Place - $100 per contingency
