aFe POWER Adds Performance to the L5P Duramax Platform

aFe POWER jumped at the opportunity to purchase the 2017 GMC Sierra 2500HD equipped with the new L5P Duramax Motor. With stock horsepower numbers advertised at 445 @ 2,800 rpm, and 910 lb-ft of torque at 1,600 rpm, we had to see what we could do to make those numbers go up. We immediately started development of an intake system for the new L5P Duramax. We started with the Momentum intake, and designed it to take advantage of the massive hood scoop that comes standard on all new 2017 and 2018 Duramax trucks. We made sure to add a large filter to help extend the cleaning intervals for the intake system, and developed the tube to eliminate any air turbulence as it travels through the tube.
When we put the truck on our DynoJet Dyno, we pulled in 15 horsepower and 37 lb-ft of torque with just the aFe Power Momentum intake alone. When we finished the Magnum FORCE Stage-2 XP intake kit, we pulled in 18 horsepower and 43 lb-ft of torque, proving just how much the L5P motor needs to breathe. We then developed our Scorcher HD Module to see just how much power we could get out of a stock system with just that modification, and were amazed when we recorded a 60 horsepower and 120 lb-ft of torque gain over stock. Combine both the module and intake together and the L5P really takes off from a standstill!
With great power comes great heat, and it’s important to keep your ride cool with upgrades like our exhaust kits, differential covers, and intercooler tubes. Those upgrades will help keep temperatures low when you start increasing the horsepower, meaning greater durability and extended performance in hot weather.
Now our 2017 GMC Sierra 2500HD feels much more responsive and sounds great under acceleration. The truck feels much different than stock, and the amount of torque to the rear wheels really plants you in the seat as you take off. Add the simple plug and play Sprint Booster module to give the throttle body a 1-to-1 throttle response, and the new Sierra 2500HD/Silverado 2500HD feels the way it should have felt right off the factory floor!
