2011 GMC Sierra in the Marketplace Packs 630 Wheel Horsepower
Looks like an average Sierra pickup, but this turbocharged truck has more power than a Corvette Z06.
The LS1Tech Marketplace is chock full of wicked, high performance General Motors vehicles, many of which are Camaros, Firebirds and Corvettes, but few of them pack as much power as this 2011 GMC Sierra. This pickup doesn’t really look like anything special from the outside, especially if you don’t notice the massive front-mount intercooler. However, thanks to a big single turbocharger setup, the odds are good that this half-ton truck will slaughter beat of the stock performance cars that make the mistake of lining up.
Best of all, it was listed for sale by “TAPyvehc93“, so this monstrous sleeper Sierra could be your weapon for the 2019 racing season.
The Machine
The details are short on this 2011 GMC Sierra 1500, but we know that it is powered by a 5.3-liter V8 with a stock bottom end, but it features worked 243 cylinder heads and a Trick Performance Products stage 3 turbo kit, which introduces a 76-millimeter turbocharger to the equation. With the help of larger fuel injectors and an E85 ethanol gasoline blend, this truck laid down 630 horsepower at the rear wheels with 13 pounds of boost pressure.
The seller points out that there is more room for tuning that would lead to more power, but the available thrust is sent to the rear wheels by means of a stock 6L80 automatic transmission with a 3,400 stall convertor, a two-piece steel driveshaft and a Detroit Tru-Trac rear differential. It appears to have some average Goodyear truck tires that likely don’t help much with launch grip, but this Sierra does have a set of VAS traction bars to help on a hard pull.
Nice, Clean Truck
Other than the big turbo kit and the supporting modifications, this is just a nice, clean 2011 GMC Sierra. The black leather interior looks very clean, with the extra gauges mounted on the A-pillar, and the exterior looks completely stock. As mentioned above, if you don’t notice the intercooler behind the grille, there is nothing about the exterior of this truck that allows it to stand out from any other 2011 GMC pickup.
According to the folks at Kelley Blue Book, a 2011 GMC Sierra SLE Extended Cab pickup with the 5.3-liter V8 and 60,000 miles has a private party value of around $18,000. Of course, that doesn’t include any upgrades, and this half-ton pickup has an array of upgrades to the engine, transmission and drive line, so this truck is priced reasonably at $23,000.
This 2011 GMC Sierra is the perfect pickup for someone who wants a fast half-ton that can still serve as a great daily driver.
