Many of the top engine builders in the world rely upon Rottler’s precision equipment for machining their engines components to the tightest tolerances, so we’re proud to have them on board!
Greg Brown Race Engines
Greg Brown Race Engines was first up for Wednesday’s qualifying eliminations running a carbureted GM LS engine package based on a factory 6.0-liter. The engine was clearly well developed and ready to run, with the engine firing readily to life. With a displacement of 435 cubic inches the engine had the size to put down a big number. As the torque gauge showed right from the hit at the bottom end, this thing was delivering the goods. Peak horsepower came in at an outstanding 741 horsepower, while torque registered 676 lb-ft at peak. The incredible overall torque curve put the engine’s score at 2768.6 points, putting Brown in second place in the current standings.
Randy Malik of RM Competition had a serious 436-cube Ford on the dyno and ready to run. This engine had not yet been run in its current configuration, though it sounded tough upon initial fire-up. An internal water leak, however, resulted in a DNF.
Robinson Ruttlers Auto Machine (RRAM)
Jesse Robinson and the Robinson Rutters Auto Machine team came to compete with a 466-cubic inch big block Mopar low deck engine. Actually, this engine was the team’s development and testing piece, but was pressed into service when the competition engine failed to be completed in time. Topped with a set of RRAM-ported Procomp heads, and trick modifications everywhere you look, the Mopar dished out 755 horsepower and 674 lb-ft of torque. The effort resulted in a score of 2590.8 points, thought Jesse tells us the competition engine left back at the shop promised even more.
SEMCO Performance led by Mike Semchee brought a 409-cube Pontiac combination that impressed. The engine featured Kuaffman heads and a carbureted induction. The team’s focus was intense, and strong power numbers followed. The Pontiac was notable for very broad torque, recording a peak of 645 lb-ft. On the power side of the equation, the Poncho delivered 645 horsepower. It was the solid overall power curve that racked up the points, finishing with score of 2633.25.
The Triple S Team of Corey Short brought a 434 cubic inch small block Mopar to the Challenge. Feeding the stroker bottom end is a pair of Indy 360-2 cylinder heads and a carbureted induction using an Indy intake manifold and Demon carb. The deep breathing combination pulled cleanly to the top of the test range, topping the 700 horsepower mark with 707 recorded at peak. Torque production was just as beefy, with as much as 649 lb-ft on tap. The team ended the qualifying session with a score of 2659.
RCS Racing Engines
RCS Racing Engines Team led by Ron Stanislawczk brought a Ford Cleveland combination using a Cleveland block and taken out to 432 cubic inches. Always intense competitors, expectations were high when the CHI-headed, fuel injected engine began its dyno session. The numbers confirmed that this thing makes very serious power, with 747 horsepower recorded at peak and 657 lb-ft delivered. It was obvious that this is a very well developed engine, ending qualifying eliminations with a score of 2705, putting the engine into fourth place.
Lynn Peterson from Kustom Kemps is an AMC engine specialist, and he came to the competition with the only AMC engine. At 401 cubic inches it was at a displacement familiar to the AMC crowd. What really made it cook was the excellent Indy heads and induction, topped by a Holley carb. This engine from Kustom Kemps made excellent power for such a straightforward piece, turning the dial to 658 horsepower, with 581 lb-ft of torque at peak. It was definitely a job well done, with the engine finished qualifying eliminations posting a strong score of 2607.6.
Our final engine to run in Wednesday’s qualifying session was the 433 cubic inch big block Chevy from Adney Brown’s Performance Crankshaft. The engine is topped with a set of Brodix heads, while the Holley intake manifold is plumbed for fuel injection but was run with a Holley Carburetor. The engine seemed to pull through the qualifying eliminations without missing a beat, turning cleanly to 7000 rpm. Tuning the timing and fuel, the team gained power with every move, with horsepower reaching a best of 718, and torque coming in at 637. The team finished with a score of 2659.7 points.
