Photo 1/21 | 2008 Gmc Sierra Burnout | That little bit of black exhaust smoke was all the GMC ever made. After that, the only smoke we saw was billowing from the rear tires.
Photo 2/21 | 6 6l Lmm Duramax Diesel | Under the hood, the mildly modded 6.6L LMM Duramax is highlighted by MPI’s compound turbocharger system.
Photo 3/21 | Cognito Traction Bars | With the truck lowered 3 inches in the rear and 2 inches in the front, Cognito traction bars help get power to the ground and keep the axle from winding up during launches at the track.
Photo 4/21 | 2008 Gmc Sierra | Dani’s ’08 GMC is right at home at her husband Justin’s shop (Advanced Diesel Works in Kalispell, Montana), even though he’s a die-hard Ford guy.
Photo 5/21 | Garett Powermax Stage 1 Unit | Which Justin modified by replacing the kit’s secondary turbo with a Garrett PowerMax Stage 1 unit.
Photo 6/21 | 2008 Gmc Sierra 2500 Burnout | After burning off the Kumho Ecstas for nearly a quarter of a mile, Justin Dall drove back and gave us that sheepish, hands-in-the-pockets “they needed to be replaced anyway,” look.
Photo 7/21 | Borgwarner S475 Turbo | The MPI kit features a BorgWarner S475 turbo that is used as the primary power-adder and retains a Duramax’s stock turbo as the secondary ’charger. Justin replaced the stocker with this PowerMax unit in an effort to move a little more air into the 6.6L.
Photo 8/21 | Fuel Filter In Engine Compartment | The truck’s stock fuel filter was relocated to a corner of the engine compartment.
Photo 9/21 | Fass Lift Pump | The FASS Platinum 150-gph lift pump delivers the fuel to the stock CP3 and injectors.
Photo 10/21 | 2008 Gmc Sierra On Dyno | After the Sierra was strapped down on the rollers at Advanced Diesel Works, the compound turbo 6.6L laid down 567 hp and 1,061 lb-ft of torque at the rear wheels.
Photo 11/21 | Dyno Results | After the Sierra was strapped down on the rollers at Advanced Diesel Works, the compound turbo 6.6L laid down 567 hp and 1,061 lb-ft of torque at the rear wheels.
Photo 12/21 | 2008 Gmc Sierra Interior | Since Dani’s ’08 Sierra 2500HD’s off-track use includes family camping excursions in the Montana backwoods, the interior remains mostly stock for comfort.
Photo 13/21 | Ppe Steering Braces | Since the GM pitman and idler arms are known for being prone to breaking, the front end is fortified with PPE braces to ensure things stay in place.
Photo 14/21 | Merchant Automotive Transfer Case Brace | This Merchant Automotive transfer case brace keeps vibration and additional torque from cracking the transfer case housing.

Photo 16/21 | Allison Transmission | The reliable Allison received a few upgrades from SunCoast and Mag-Hytec to help handle the Sierra’s power and the stresses brought by towing and racing almost every weekend.
Photo 17/21 | Afe Exhaust | AFE’s 4-inch exhaust keeps the Duramax’s noise levels low. We dig the 5-inch tip.
Photo 18/21 | 2008 Gmc Sierra Burnout | That little bit of black exhaust smoke was all the GMC ever made. After that, the only smoke we saw was billowing from the rear tires.
