You guys may be interested in the article in the latest Diesel Progress about racing big trucks in Europe. 12000 lb. rig, 0-100 in 7. 9 seconds! The truck in the article had C12 Cat, upped to 3400+ torque, and 1400 Hp. if I remember correctly. Cat claimed 2 races were worth 3 months of dyno time. Just make sure you have an apron to wear the rest of the afternoon;-)
