2008 Dodge Challenger Drag Pack
Owned by: Chrysler Group, LLC
Auburn Hills, Michigan
- Engine: As the test bed for the new aluminum new-Hemi block, a 440-inch Hemi is situated under the Six-Pack hood. The block is a Mopar Performance item, PN 5153898, with a forged rotating assembly consisting of Diamond pistons, Scat rods, and a Scat crank. Compression is a boost-ready 8.56:1. A single 88mm Y2K ball bearing Turbonetics turbo uses the exhaust gases to increase atmospheric pressure by 15psi, controlled by a Turbonetics New Gen HP wastegate. This compressed air is then chilled in a Turbonetics air-to-water intercooler before being fed into an aluminum intake. Fuel is added through a set of Mopar Performance fuel rails and injectors delivered from the tank by a high-flow Weldon pump. From there, the mixture is escorted into each cylinder by a set of experimental cylinder heads. Once the Mopar 392 camshaft has opened the valves, it's ignited, sent out to the turbo to begin the cycle once again, and through an open downpipe.
- Rearend: An MPR/Strange unit with 3.70 gears and 40-spline gun-drilled axles. It features an aluminum carrier and pinion support.
- Transmission: The shifting is performed by an ATI two-speed Pro Glide with a nine-inch torque converter designed for use with boost.
- Suspension: Currently the Challenger uses Afco adjustable drag shocks but will soon be swapped for Strange shocks. The rear suspension was designed by MPR Racing and is a four-link with a panhard bar.
- Brakes: Strange drag brakes.
- Wheels/Tire: In these photos you'll see 9x30-15 Goodyear slicks with 27-inch front runners. They have since switched to a 9x30-15 Hoosier slick with 28-inch skinnies.
- Paint: A "Liquid Metal" Direct Connection wrap.
- Interior: A slew of Mopar/AutoMeter gauges, switches and buttons are required in such a serious quarter-mile contender. A Mopar tach communicates what the Hemi is spinning to while the driver sits in the Viper-sourced seat.
