Video: Bolt-on Mods Create a 550+RWHP 2008 Shelby GT500


To continue our Bolt-on Build-up series, we’ve taken a stock 2008 Shelby GT500 boosted the power to over 550 rear wheel horsepower, all with only basic bolt-on modifications. If you like what you see in Stage 1, complete the series by checking out Stage 2 and Stage 3 as well!

Everyone who knows their Mustangs should also know the Shelby GT500 is a supercharged monster straight from the factory. In fact, the 2008 Shelbys already had 500 horsepower at the crank, but with the 2015 Mustang packing something in the range of 450 crank horsepower and the 2013-2014 GT500’s Trinity motor pushing 662HP, the older Shelbys might start to seem a bit underpowered. If you’re thinking the older snakes can’t run with the newer herd anymore, you’d be dead wrong.

With only a handful of basic mods, we were easily able to bump the power and boost levels on our 2008 GT500 and put more power to the tires than the newest GT500. The video series broken up into three stages maps out how anyone can take a stock 2007-2009 GT500 and add around 200RWHP with minimal work and time invested.
