Robert Peters (Team 41) and the RTD team kicked off the AMSOIL Engine Masters Challenge for 2012 with a fuel injected small block Chevrolet combination. The Holley EFI system featured a massive Dominator style throttle body on the relatively small 363 cube powerplant. The hedge here was a uniquely modified intake manifold which was designed to deal with the massive airflow potential. Unfortunately, tuning problems showed up right from the start, with what seemed to be an impossibly lean air/fuel ratio. The engine struggled under load, and no amount of tuning seemed to influence the problem. The team did manage to complete the required three qualifying pulls, but the engine’s tune was definitely way out of the ballpark. A best peak torque of 527 lb-ft of torque did show the engine’s potential.
The University of North Carolina At Charlotte
Score - 2292.9
University of NC at Charlotte NC (Team 40) ran second, running another small block Chevy combination, this one displacing 403 cubic inches. The Accel DFI system equipped engine seemed well prepared, and fired cleanly seemingly close to a working tune. The team members confidently worked the tuning tables to optimize the combination. Things seemed promising in early running. Unexpectedly, the power numbers showed a significant drop, seemingly losing a cylinder. The team persevered, making the three qualifying pulls for a score of 2292.9, but the team was obviously disappointed as the engine scored well below its potential.
Score - 2047
TNT Engineering headed by Tony Bogovich was third on our roster, running a 308-cube combination based on a Ford Boss 302. With a top end consisting of ProComp cylinder heads, there seemed to be plenty of cylinder head to make the engine breathe. Unlike our first two fuel injected competitors, this engine featured a Quick Fuel carburetor and a two plane intake manifold. The engine ran flawlessly through the qualifying process, but the overall power curve seemed a little light for a score of 2047, with peak output recorded at 400.7 horsepower and 365 lb-ft of torque.
Score - 2188.4
The big Ford Shotgun Hemi engine from TM Enterprises generated plenty of attention with its elaborate fuel injection system and apparent dual-plug configuration. These new twin plug heads from TM are not legal in the street division in dual plug form, so the team simply mocked-up the secondary set of plugs to fit the rules of the event. With 545-cubes of exotic Ford on the dyno, the attention level by all in attendance was high. The team clearly had the engine management system close right from the start, focusing on optimizing and tweaking for max power. The engine pulled cleanly, posting a best of 751 horsepower and 704 lb-ft of torque, finishing with a score of 2188.4.
Score - 2077.8
Return competitors Kustom Kemp always brings AMC power to the show, this time with Lynn Peterson and the teams putting together an OEM based short stroke combination featuring modified production iron heads. The engine displaced 361 cubic inches, and was equipped with a four barrel carburetor. Peak power turned in by the effort was 445.9 hp, while torque checked in at 430.3. This engine is representative of good street power from basic AMC parts. The team finished with a score of 2077.8.
Ray's Dyno & Machine
Score - 2228.3
The Pontiac crowd was represented by Ray Clayton and his team from Ray’s Dyno & Machine. Ray had intended to run a fuel injected combination atop his 408-inch Poncho, but with a variety of issues cropping up as time to the competition running out, and Edelbrock dual plane intake and 4150 carburetor were substituted to make the show. The clean Pontiac was exceptionally smooth through the pulls, effortlessly completing the three qualifying runs. With peak power recorded at 546 hp, and 535 lb-ft of torque, this would be a sweet running engine in any Pontiac muscle car. The engine finished with a score of 2228.3
Henderson Power Sports
Score - 2298.2
Henderson Power Sports and the team led by Chris Henderson brought another small block Chevrolet, a 408-cube combination featuring an Accel DFI injection system and a set of AFR 235 cylinder heads. This engine was prep and primed and ready to turn a number, handily passing the 600 horsepower mark, and building plenty of torque along the way. When the dust settled from the final qualifying pull, Henderson completed the day in the number one position in the Street Division, posting a score of 2298.2 points, making peaks of 612 hp and 546 lb-ft of torque.
