DynoMax Power to the Wheels Dyno Tour - Seven Cars: 9,565 Horsepower

Third Place, $5,000
Darren Tedder
'71 'Cuda
605ci KB Hemi
1,435 rear wheel horsepower

Darren's Hemi was the only non-super/turbocharged car in the top three. Next year, his plans call for a 14-71 blower and nitrous. Wahoo!>

Darren was the only guy in the top 10 with a Hemi and the only one without a blower or turbo. He made up for this by loading the biggest engine in the competition with two stages of nitrous. He originally qualified with a 572ci Hemi but built this 604 to push the envelope. His approach wasn't without its share of drama. Mere days before leaving his Georgia home for Las Vegas, the big Hemi scorched a piston during final testing. He called his friend Dave Calvert at CP pistons who found a set of pistons and overnighted them to Darren. "My motor was in a million pieces on Tuesday, and we were leaving Thursday morning," he said. Then, as Darren and good friend Richard Burdette neared Las Vegas, Richard developed an aggravated ulcer and had to be rushed to the hospital, missing the entire event. Despite all these distractions, Darren barely missed Second Place by a mere 20hp with a 1,435-rwhp effort.
