Turbo GMC Sierra – Double the Output

October 14th, 2019

Greetings drag racing fans and speed freaks of every ilk. So, you want to go fast but just can’t shake the appeal of your full-size pickup? I can relate. What if you could retain the stock appearance of your GMC/Chevrolet Sierra/Silverado and double the horsepower? I say, heck yeah. Just sell me the recipe. Well, here it is for free.

This video takes us on a journey – from stock to totally outrageous. It all begins with a bone stock 2008 GMC Sierra 1500 2WD with a 5.3-liter V8 engine and an automatic transmission. From the factory, this tough truck is capable of producing 315hp and 338 lb.-ft. of torque. Not too bad, but it’s going to get a lot better.

As you can see in the video, Strictly Performance Motorsports got ahold of this pickup and went hog wild and pig crazy. The key component of this radical modification is the Strictly LS Truck Turbo Kit. It consists of virtually everything you will need in the way of a turbocharger (Precision), an intercooler, all the tubing and all the piping. There are also turbo exhaust headers, wastegate, clamps, brackets and so forth. They upgrade the camshaft to a Brian Tooley Racing Stage II Turbo Cam. The cylinder heads are treated to some porting and polishing, and the torque to yield head bolts are replaced with stronger studs and nuts.

Once everything is put together, the truck is ready for the dyno. Wow! This mod was certainly a huge success – 737.8whp and 800lb.-ft. of torque!

Now, it’s time to bring the truck owner in and let him take his first test drive. As you can imagine, he is in for a shock. Check it out.
