Score - 2238
Adney Brown with Performance Crankshaft was the first engine on the schedule for the final day of qualifying eliminations, running a big block Chevrolet featuring Broxix cylinder heads, an Edelbrock single plane intake manifold, and a Big Stuff 3 EFI system. With fellow competitor Barry Rabotnic working the tune, the big Chevy picked up with each tune-up change. With the engine dialed in it posted a best peak horsepower of 597 in the scored qualifying pulls, while delivering 561 lb-ft of peak torque. The effort was worth a score of 2238 points.
Jon Kaase Racing
Score - 3277
Jon Kaase Racing came in to the Xtreme Division competition with a ProStock-style big block Chevrolet featuring Reher Morrison cylinder heads, a serious tunnel ram intake manifold, and a pair of Dominators. The 537 cubic inch powerplant was ready to roll, and on first fire-up there was no mistaking this is a race engine. Going into a test pull, Kaase simply reviewed the numbers, checked the plugs, and ran into the scored qualifying tests with no tuning changes. Reving cleanly to the 8000 rpm, making peaks of 1133 horsepower and 886 lb-ft of torque. At this point in the competition, Kaase is leading Xtreme with the highest point score, as well as leading the field in peak horsepower and peak torque, finishing with a score of 3277 points.
Power Shop Racing Engines
Score - 2425.9
Joe Carroll and the Power Shop Racing Engines team brought a healthy 402 cubic inch small block Chevrolet to compete in the Street Division. Featuring Racer Pro cylinder heads, an Edelbrock AirGap intake, and a 4150-style carb, this engine looked like the kind of piece that would be at home in any high performance street machine. The Chevy performed perfectly and with some minor carb tuning produced peak numbers of 592 horsepower and 553 lb-ft of torque. The engine completed qualifying eliminations with a score of 2425.9, enough to put it into second place in the current Street Division standings.
Scott Main and Bob Moore from MPG Head came to the Street Division with a CHI-headed Ford small block combination displacing 405 cubic inches. These guys are regulars at the Engine Masters Challenge competition and are always a team to watch. The mechanical waterpump presented a problem upon start-up, with the very underdriven mechanical drive system refusing to circulate water through the system. A waterpump drive system change ate a large portion of the teams qualifying and tuning time, but MPG persevered. The engine finished qualifying eliminations making peak power numbers of 613 horsepower and 558 lb-ft of torque for a score of 2366.2.
School of Automotive Machinists
Score - 3300.2
The School of Automotive Machinists were our next competitors with a 402 cubic inch Chevrolet SB2 combination in the Xtreme Division. The beautifully detailed engine featured a single Dominator carb on an Edelbrock manifold. The team was obviously well prepared as the engine came to life and functioned perfectly with the first turn of the starter motor. Working through the three required qualifying pulls with plenty of time to spare, this hot Chevrolet displayed tremendous power, with peak numbers of 853 horsepower and 665 lb-ft of torque. The effort resulted in a qualifying score of 3300.2, putting the School of Automotive Machinists in the current first position in the Xtreme Division.
Racing Engine Design
Score - DNF
Bret Bowers and Racing Engine Design experienced trouble with a mysterious electrical issue, which was preventing the engine from starting. The clock wound down considerably before the crew had isolated the issue and the engine started, leaving virtually no time for tuning. With the clock nearly expired the team made a heroic attempt at a pull, but were too far away from the tuning window for it to complete its qualifying runs. The team retired from qualifying with a DNF.
BES Racing Team
Score - 3214.3
Tony Bischoff and the BES Racing team came with a radical SB2 Chevrolet small block combination to compete in the Xtreme Division. Displacing 465 cubic inches and sporting a tunnel ram intake manifold with dual Dominator carbs, the engine looked to have the parts to produce serious power. The team was hamstrung by a component failure prior to the event, meaning the final engine assembly was barely completed in time for the Challenge. Tony was concerned because the engine was scarcely tested before coming to the competition. The engine certainly delivered huge power, with 1007 horsepower on tap. Torque production was also good at 742 peak, but Tony was disappointed with the torque curve down low. The engine completed qualifying eliminations with a score of 3214.3 points to put them into Third place in the current Xtreme Division standing.
McKeown Motorsports Engineering
Score - 3087.1
McKeown Motorsports Engineering brought a small block Ford Cleveland based on the first aftermarket Cleveland aluminum block utilizing the Victor Glidden SC1 cylinder heads and a tunnel ram intake with dual Dominators. This 444 cubic inch engine had what it takes to produce serious output, but an electrical glitch seemed to plague the team. Time was lost in trying to get the engine started, and further difficulties occurred as the timing seemed unresponsive to inputs from McKeown's tuning computer. The team worked through the troubles, completing the three required qualifying pulls, producing peaks of 932 horsepower and 692 lb-ft of torque in the process. McKeown finished with a score of 3087.1
