A Air comes courtesy of three S400 turbos built by Engineered Diesel. The small (high pressure) turbo is 72 mm, while the two atmospheric turbos are 75mm monsters.
B Custom-braced sheetmetal intake manifold by Wehrli Custom Fabrication capable of withstanding 100 psi of boost.
C Bottom end built by Pfeiffers Engine Specialties, with Carrillo connecting rods, Mahle Motorsport forged pistons, and a stud girdle.
D Fuel is handled by two custom-mounted CP3 pumps (plus a third in the stock location in the engine valley); 150-percent-over injectors by Exergy Engineering complete the fuel puzzle.
*All this power comes in a lifted ’02 Chevy Silverado with a Dana 60 solid front axle swap.
Back in the day, a single CP3 pump and single-turbo Duramax could support you until about 600 hp, but that was it. A few years later, with dual CP3 pumps and compound turbos, 800 rwhp was a reality. Thanks to these “twin everything” trucks, we’re now in the stages of stroker CP3 pumps and mammoth turbos, which can make upward of 1,100 rwhp on a street-driven Duramax.
But what if you want more? Well, Jason Wehrli, from Sugar Grove, Illinois, has a solution. He has just fabbed up the first “triple everything” truck, featuring triple CP3 pumps and three turbochargers. With more than 100 psi of boost and insane amounts of fuel, we think he’s looking at 1,200 to 1,600 rwhp worth of fuel and air. If the engine can take the power without exploding, we may be looking at a new trend here.
