There aren't many people who like smoke as much as Albuquerque's Max Moya. Not only does he have a heavily fueled 12-valve Dodge, he is also a full-time firefighter. But Max was burning tires long before he was running into burning buildings. He has owned the '95 Dodge 2500 shown here for more than ten years and has put more than 160,000 miles on the truck.
Instead of using stock replacement parts, Max took the opportunity to upgrade. The fact that he worked as a foreman at a truck customizing shop before becoming a firefighter didn't hurt matters either.
Plenty of Power
A number of turbos have been used on the truck over the years. Some surged, some were too slow to spool, and others were not reliable enough. But like Goldilocks and the three bears, the current turbo is just right. It is a Super 71 from High Tech Turbo, with a 71mm turbine, 64mm compressor wheel, and 14mm wastegate housing. The turbo inhales through an AFE Stage II intake and exhales through a 4-inch mandrel-bent exhaust with a 5-inch tip. These are fairly standard modifications, but the Piers Diesel Research (PDR) quick-spool camshaft goes way beyond the norm. The cam provides faster turbo spooling, lower EGT, and increased fuel economy thanks to the higher lift, longer duration, and improved lobe separation.
All that air is mixed with diesel fed to the Cummins by a Holley blue lift pump and then pressurized by a 215hp P7100 injection pump off a '96 Dodge. The pump works with a custom cam plate, 4,000-rpm governor spring kit, heavy-duty valvesprings, and custom delivery valves from PDR. All of the fuel is then injected into the cylinders with Bosch 370 injectors.
