A pile of cracked heads and blocks were stacked in the corner. Experimentation has its price. Zane gave us a quick overview of the $30,000 engine that pumps out nearly 800 horsepower. Two high-pressure oil pumps are stacked, one for each bank of injectors. A stock injector flows 120cc of fuel. The ones Zane runs push 500cc. Heads were modified to handle the extreme boost, like 90psi on the track with ETG running 1600 to 1700 degrees.
This kind of fuel needs lots of air. The primary turbo came off a 31-liter Perkins Generator. It's about 10 times the size of a stock unit. The second turbo is only twice the factory size. A divorced wastegate keeps control of the pressure out of the secondary turbo and dumps it back into the main turbo, so no energy is lost.
An E40D transmission built by BTS in Arkansas sends power to Toyo Proxes S/Ts on American Racing 20x10 wheels. We took a quick spin around the block. Zane punched it about halfway down the street, and when he backed off, the speedo was at 95 mph.
Applying the NHRA altitude correction factor for Rocky Mountain Raceway (4400 feet above sea level) of 0.9566 for time and 1.0412 for speed and dividing by two for turbocharging, Zane's corrected time is 11.945 at 116.35 mph. That's faster than a stock C5-generation Z06 Corvette and comparable with a Ford GT and Lambo Gallardo--at more than twice the weight.
Day two of Weekend on the Edge brought everyone to the Edge facilities in Ogden, Utah, for a Dyno Day, barbecue, and a show 'n' shine. The three dynos were kept busy all day. John Kennedy took top honors, with 725 horsepower and 1373 pound-feet of torque. The real shootout would've been between the ATS Duramax and the Wide Open Performance Power Stroke, but both trucks developed unknown problems with one of their injectors, keeping us all guessing and waiting for next year's Weekend on the Edge.
