Qualifying eliminations in the 2013 AMSOIL Engine Master’s Challenge was kicked off with a Pontiac engine fielded by Throttle Performance. Although this team is new to the event, they were clearly experts in the engine building field. Among the crew was veteran Challenge tuner Scot Clark, while noted author David Vizard was included as a special guest and advisor. The 428 cubic inch fuel injected Poncho proved extremely strong, posting peak numbers of 738 horsepower and 653 lb-ft of torque. The crew worked expertly in the test cell, with tuning accomplished via a computer link in the control room. We were impressed to see substantial power gains with every tuning move. Throttle performance opened the competition with a very strong score of 2742.2 points.
