What Happens If You Turbo a 5.3L Yukon With No Other Mods? Lets Find Out! (Uncle Rob Hits the Dyno)

What happens here

Following the driveshaft failure, the team improvises a solution by swapping the driveshaft with one from a customer's truck temporarily. With the driveshaft replaced, they resume dyno pulls. The Yukon now produces 700 horsepower and 800 lb-ft of torque, a substantial gain. After the dyno session, the team takes 'Uncle Rob' for a street test, highlighting its performance and driveability.

Goal: Replace driveshaft, re-dyno, and test real-world performance.

Tools and materials

  • Dynojet Dynamometer Dynojet — Final power validation
  • Floor Jack — Lifting the vehicle for driveshaft access
  • Jack Stands — Securing the vehicle while working underneath
  • Replacement Driveshaft — Temporary replacement for the broken driveshaft
  • Wrenches — Removing and installing driveshaft bolts
