Photo 7/27 | 001 Titan | Here’s the collection of AFE Power parts we hope will wake up our ’17 Nissan Titan XD. The AFE Momentum HD air intake, Scorcher HD module, and large-bore, post-DPF exhaust are set for making our 5.0L Cummins-powered truck a lot more fun to drive.
Photo 8/27 | 002 Titan | We strapped the truck down to the Dynojet chassis dyno at DMC Racing in Halifax, Massachusetts, and recorded a baseline of 267 hp and 428 lb-ft of torque. When a 15 percent adjustment is made for the truck’s drivetrain (transmission, driveshaft, and rearend), the numbers support Cummins’ engine-dyno ratings of 310 hp and 555 lb-ft.
Photo 9/27 | 003 Titan | This is the AFE Power Momentum HD air-intake system. Everything here is included when it is purchased as part of the Momentum Scorcher HD Combo Pack. The snorkel-style ram-air scoop is optional. The filter is an oiled Pro 10R element that flows 1,000 cfm.
Photo 10/27 | 004 Titan | The truck’s stock sensors are removed and retained for reinstallation with the Momentum HD intake. Basic handtools are necessary and anyone with a driveway (or even a parking space) and general mechanical skills can perform this job.
Photo 11/27 | 005 Titan | AFE Power provides clear and detailed installation instructions with all its products. Directions are also available online in the event you misplace the paper copy. There are plenty of photos included that can help guide you if you ever get stuck.
Photo 12/27 | 006 Titan | In this photo, Street Diesel Performance owner Sean O’Hara has the Momentum HD system set in place and is checking the fitment of the tubing before locking down the clamps. The air filter resides in the large airbox with a clear top.
Photo 13/27 | 007 Titan | Note the plug in the front of the airbox. That’s where the ram-air-style snorkel fits. The snorkel is included with the Momentum Scorcher HD Combo Pack. However, it can also be ordered individually.
Photo 14/27 | 008 Titan | Here’s a better look at that snorkel we mentioned and the instructions for properly locking it down. We saw small power gains with the air-intake system alone and then a far more significant increase with it. A new total of 274 hp and 435 lb-ft has us on our way to making the Titan XD more powerful.
Photo 15/27 | 009 Titan | This is how the snorkel looks installed. As good as the power gain we recorded on the dyno is, we can imagine that on the highway at 70 mph on a cool day, you’ll really feel some additional scoot.
Photo 16/27 | 010 Titan | This 5-inch, mandrel-bent, stainless steel tubing flows more than 65 percent better than the stock pipes, according to AFE’s engineers. We’re adding the cool 6-inch black tip as well.
Photo 17/27 | 012 Titan | Sean O’Hara of Street Diesel Performance removes the stock exhaust system as one piece. Using a brand-new truck makes the exhaust removal and installation process incredibly easy.
Photo 18/27 | 013 Titan | Here’s a comparison between the factory exhaust and AFE Power’s much larger exhaust system. While we are working “downwind” of the DPF, the larger-diameter pipe should enhance the engine sound.
Photo 19/27 | 014 Titan | The new exhaust includes high-quality clamps and hardware. The tailpipe hanger mounts in the stock rubber frame receiver, making installation a snap.
Photo 20/27 | 015 Titan | Factory-style locating notches are incorporated in the exhaust tubing to ensure it is properly aligned.
Photo 21/27 | 016 Titan | Finished off with a 6-inch tip, the AFE Power exhaust setup definitely looks much better than stock. It also sounds better, and it actually does make a little more power over the original exhaust pieces. We picked up 1 hp and 10 lb-ft over the stock system.
Photo 22/27 | 017 Titan | This AFE Power Scorcher HD module is the key to unlocking the full potential of the 5.0L Cummins V-8. Designed to install with no cutting or permanent link to the truck, the programmer features four separate power settings.
Photo 23/27 | 018 Titan | After locating a spot in the engine bay for securing the module, Tyler Brancifort of Street Diesel Performance runs the Scorcher HD module’s small wiring harness to the MAP and fuel pressure sensors.
Photo 24/27 | 019 Titan | The stock-style connector plugs in between the MAP sensor and the plug. With the MAP sensor on the top of the engine, this is the easier of the two connections to make. OEM-style connectors on the Scorcher HD module’s wiring harness ensure the connections are weather-sealed and will last for a very long time.
Photo 25/27 | 020 Titan | The one-button controller can be mounted virtually anywhere and allows the driver to switch on the fly between Stock, Sport, Sport-Plus, and Race calibrations.
Photo 26/27 | 021 Titan | This light on the controller indicates which performance setting is being used. We saw our ’17 Nissan Titan XD’s power leap from 271 hp and 439 lb-ft of torque with the module set in the Stock mode to more than 324 hp and 532 lb-ft in Race mode. Sport and Sport-Plus also provided solid gains over the truck’s initial baseline of 267 hp and 428 lb-ft.
Photo 27/27 | 023 Titan | With just a few hours of work under our belt, we had transformed this Titan from a rather mundane stocker to a very fun to drive rig that has more torque for towing and hustles down the road at lot better than it did before we started our project. The AFE Power Momentum Scorcher HD Combo Pack and large-bore exhaust lives up to our expectations.
