2011 AMSOIL Engine Masters Challenge - Balance Of Power

As if the more radical specifications weren’t enough, the 2011 Challenge upped the number of competitive entries by a substantial margin, pitting 40 invited entries into fray, versus the 30 places in previous events. With the greatly expanded roster, the running of the competition was also significantly altered. The old testing regime was tossed for an all-new procedure. Rather than the old routine of a series of three warm-up pulls, followed by 20 minutes of tuning and three back-to-back scored pulls, the new procedure gives the competitor 18 minutes to use as they see fit to complete three scored pulls, after completing a single required warm-up pull. Yes, the stage was set, and when the curtain was raised on the 2011 Challenge, the action didn’t disappoint.

At the University of Northwestern Ohio host facility, two dyno cells are on call for the running of the Challenge. With two classes of competition, the logical choice was to run all the engines in a given category in the same test cell. On the first day of qualifying, we had scheduled 10 engines to run: five in the Street category in cell one, and five in Xtreme running in cell two. The Street roster included Ray’s Dyno and Machine’s Pontiac, Stine’s Chevy big-block, and Robert Peters, Randy Ferbert, and Rick’s Custom Engines all with Chevy small-blocks. Stine’s big-block shined in terms of brute power, enough to eventually take the crown for the highest peak power and torque in the Street category, while the Ferbert Chevy earned the highest score, all the more impressive considering the engine featured OEM iron Vortec cylinder heads. In Xtreme, only two engines progressed into qualifying, the Miller small-block Mopar, and Race Car Services of America’s Glidden-headed Windsor. The W8-equipped Mopar handily outscored the competition and finished the day in the top spot for Xtreme.

Day two saw the Hinkle Chevy big-block, Porting Dynamics and Racing Engine Design with LS Chevys, Raceheads running a Windsor Ford, and Robinson Analytical sporting a small-cube Olds in Street. When the smoke cleared, Bret Bowers and the RED team pushed its way into the lead position with a smoking score of 2,411.3, Dave Storlien and the Porting Dynamics team did not run due to an ignition problem, and were eligible to come back in an alternate position, if they could find one. In Xtreme, Elan Power Products kicked off the day with a radical, road-race–derived Ford sporting Yates C3 heads. The engine smashed all previous competitors in the category, and more than eclipsed the Dove FE and Hinkle SB2 that followed. The Triple S team was eligible for an open alternate spot due to a did-not-start.

It all came down to the final day of qualifying, with some of the competition’s noted heavy hitters yet to come to bat. In Street, the lineup included RM Competition and Weingartner with Chevy small-blocks, Automotive Machine and Performance with a Buick, TPIS running an LS, and Power Shop with a Clevor Ford. One by one they ran, but none could bust the numbers set previously to qualify for the finals. The story proved different in Xtreme however, with McKeown and BES running SC1 Fords, Race Engine Design and SAM’s both fielding SB2 Chevrolets, and finally multiyear champion Jon Kaase with an incredible Shotgun Ford. When the numbers were tallied, McKeown, BES, and SAM all made the qualifying field, dropping the previous leaders out of contention. Kaase’s monster Ford produced a spectacular 1,182 hp from its 604 ci, but fell short of the mark. McKeown, BES, and SAM were all solidly over the 2 hp per cubic-inch level, leaving little doubt that these Xtreme engines lived up to their name.

Leading up to the finals, it was anyone’s guess how things would shake out. In Street, we had Storlien with his Porting Dynamics LS pitted against the SAM Ford and RED’s LS. Of the three it seemed Storlien had the most left in his tune, but the SAM was solidly ahead in qualifying, while Bret Bowers and RED are never ones to underestimate. Disaster struck the RED team, however, when the engine would not communicate with the EFI management system. The engine was barely capable of running during final eliminations, but it did complete the required pulls to lock in the Third Place position. Storlien wisely decided not to risk it, and ran the engine in a conservative tune for Second Place. SAM entered the finals with a substantial lead in qualifying for the Street division, and methodically ran through the final elimination pulls, finishing with almost exactly the same score earned in qualifying for a compelling victory.

We enjoyed seeing these builders show their stuff with two different categories of competition. The Street engines reinforced what we already believe—outrageous power can be made with moderate specifications and components. The Xtreme class breaks new ground on the type of engines in the game at Engine Masters, and it illustrates the kind of insane power these guys are capable of when they are set loose. At over 2 hp per cube for the leaders, there is no denying the engine-building talent. We will soon be featuring some of these engines in-depth throughout the year to give you the full scoop on where that power and torque is coming from.
