Remember the days of staring out of the window of your algebra class, day-dreaming about someday belting yourself in behind the wheel of a real race car? NASCAR racing has become the #1 American spectator sport, as it has attracted millions of people, both young and old alike. In '95, NASCAR introduced its new premiere racing series, known as the Super Truck Racing Series. The fullsize race trucks eventually became known as the Craftsman Truck Racing Series in 1996, which is still the major sponsor today. Due to its popularity, it filtered down to the grassroots racers. Local tracks began promoting minor-league truck racing.
Jay Rutherford and Mike Face introduced Speed Truck Challenge Racing in 1995, which later became the ASA Speed Truck racing series in 1996. It is now celebrating the 11th season as the leading grassroots truck racing series in North America. Currently, the ASA Speed Truck Challenge Racing Series is being televised on the Versus Network-formerly the Outdoor Life Network-and is viewed in more than 400,000 homes. The '07 racing season takes the ASA Speed Trucks to 10 different tracks for a 12-race schedule. These tracks are located throughout California, Arizona, and Nevada from small 1/4-, 5/16-, 3/8-, and 1/2-mile ovals and 1.7- and 2.1-mile road courses.
Chris Hines is the ASA Speed Truck racing series "Head Crew Chief." He oversees the fabrication and building of the trucks out of Hype Manufacturing and Arrowlang Racing located in Scottsdale, Arizona. He was coaching teenage driver Jacob Hawkins at the beginning of the racing season. After four races, Chris decided to remove the young gun and put seasoned gunslinger, Scott Franchmone from Garden Grove, California, behind the wheel of the #1 Arrowsmith Racing Chevy Colorado.
The Anatomy of an ASA Speed Truck:An ASA Speed Truck chassis is constructed from 2x3-inch mild steel, 0.120-inch wall, rectangular framerails and 1.75-inch-diameter, 0.90-inch wall round tubing. It is gusseted at every corner and intersection of the 12-point rollcage. A four-bar driver-side crash section was also plated to protect the driver from side impact.
The independent front suspension (IFS) was designed by using tubular upper and lower control arms from the authorized racing manufactures, such as AFCO, Lefthander, Joe's, and Howe. Only the factory-style front spindles from Lefthander-no dropped spindles-are permitted. PRO adjustable shocks or Doetsch Tech coilover shocks are allowed. Speedway Engineering aluminum front Hubs and Wilwood 11.750-inch-diameter 0.810-inch-thick vented, steel, brake rotors. A Wilwood hanging clutch and brake peddle assembly was easily mounted to the firewall. The GM OEM steering box, with power steering, is available as 12:1 or 16:1 from AGR or Sweet Manufacturing. The front aluminum wheel hubs from Speedway Engineering and a Lefthander front sway bar complete the front suspension equation. The ASA Speed Truck wheelbase was set at 108-inches.
The rear suspension is of a three-link and Panhard-bar design. A PRO aluminum body and adjustable coilover shocks control the rear suspension. Meanwhile, the stopping power comes from two Wilwood 11.750-inch vented steel rotors with stock GM calipers from Lefthander. To achieve a balanced braking system during the race, a Lefthander brake-bias adjuster was installed. All ASA Speed Trucks race on Allied or Bassett Racing 15x8-inch wheels and ASA Speed Truck spec Hoosier 27.0/8.0-15 tires 2070 spec.
The ASA Speed Truck Racing series has only one engine builder and that is Van Gordon Racing Engines in Upland, California. The GM Vortec 350ci V-8 crate engine was delivered directly to Van Gordon Racing where it received a mild buildup. Some of the improvements included an Edelbrock RPM aluminum intake manifold that was capped with a Holley 4412 2 BBL. 500cfm carburetor with a 1-11/16 throttle bore and a 1-inch tall spacer. The carburetor is fed from a Carter 125-gallons-per-hour, electric fuel pump. The OEM camshaft was replaced with a more aggressive bump-stick. After these spec engines have received their added performance components, they were dialed in on the dyno and sealed. Their final dyno numbers were between 350 hp and 365 hp. A 14x4-inch K&N air cleaner keeps the engines internals clean. The MSD 6 PN 6200 or Mallory coil box charge the Moroso HEI distributor and Moroso Ultra 40 spark-plug wires. The Arrowsmith Racing 360-degree stainless steel headers (Schoenfeld 360-degree header PN 135H) flow into the Hype 3-inch Y-pipe exhaust system and a 3-1/2-inch-diameter Spin Tech muffler (PN STC-02). An Optima Red Top dry-cell battery supplies reliable electrical charge for the truck's electrical system. And a Hype wiring harness links all of the electrical components together.
The driver sits in an SFI-approved Ultra-Shield aluminum racing seat, which is complete with driver left and right head restraint supports, left and right shoulder supports, and left and right leg supports. A five-point SFI-approved Crow safety harness secures the driver firmly in the seat. For easy in and out access for the driver, a 15-inch-diameter quick-release steering wheel is attached to the collapsible and adjustable steering column. An SFI-approved Simpson window net keeps debris out and the driver's head and extremities in. The Auto Meter ProComp tachometer has memory recall, which gives the driver and crew valuable engine rpm numbers. An aluminum gauge and switch panel house the Auto Meter oil pressure and water-temperature gauges. And, it also houses the Longacre switch panel that houses the electric fuel pump, engine start button, engine electric fan, and the helmet fan.
There are currently seven different fiberglass bodies available: the Chevy S-10, the Chevy Colorado, the GMC Sonoma, the Ford Ranger, the Dodge Dakota, the Nissan Frontier, and the Toyota Tacoma. The roof of the truck cab cannot exceed 72 inches in height. An aluminum tonneau cover encloses the bed, with a 7-inch tall spoiler, which is set at 35 degrees. Six-spoiler stiffeners maintain a constant angle. The minimum weight of an ASA Speed Truck is 2,650 pounds, including the driver.
