1000HP 2013 Shelby GT500 Review: The SCARIEST Mustang Ever?

The 2013 Shelby GT500: A Raw Powerhouse

• 💡 The 2013 Shelby Mustang GT500 is described as a legendary and raw car, particularly noted for its 5.8L supercharged engine and significant low-end torque.
• ⚠️ It's considered one of the scariest stock cars due to its raw nature, solid rear axle, and the way power is delivered, leading to potential instability over bumps.
• 🚀 This generation is seen as the "swansong" of old Ford and Shelby, distinct from the Coyote engine, offering a different, more visceral driving experience.

Andrew's 1000HP GT500: A Rebirth Story

• 🛠️ Andrew of Mustang Lifestyle acquired this GT500 in a blown-up state and rebuilt it into a 1000 horsepower beast with a built engine, forged pistons, and a Whipple 4.0L supercharger.
• 🧠 The engine build was budget-conscious, using off-the-shelf Wiseco pistons without sleeves, a risky approach that has held up through multiple dyno pulls.
• 🚗 A unique backstory reveals this car was Shelby's own test mule, used for R&D, evidenced by cylinder pressure sensors drilled into the heads, adding to its historical significance.

Performance and Driving Experience

• ⚡ The car delivers diabolical acceleration, with the reviewer experiencing intense G-forces and being genuinely surprised by its speed, even when accustomed to fast cars.
• 💨 The 1000+ horsepower is described as controllable, with a significant "squat" as the car hooks down and launches forward, providing a thrilling sensation.
• ⚠️ A noted issue is the third gear's tendency to grind slightly, and the long stock gearing (originally 3.31, now 3.73 in this build) contributes to its aggressive acceleration but also challenges traction.

Legacy and Horsepower Wars

• 🌟 The 2013-2014 GT500 is highlighted as a car that started the horsepower wars in the domestic auto industry, preceding vehicles like the Hellcat and Demon.
• 💰 Its original price point for 662 horsepower was considered astonishing and "bananas" at the time, especially with a warranty.
• 🚗 The difference in market value between the 2011-2012 and 2013-2014 GT500 models reflects the significant upgrades, including the 5.8L engine, larger blower, and improved aesthetics.

Behind the Build and Future

• 🔍 The smoking issue that led to the engine rebuild was traced back to leaking cylinder pressure sensors, a consequence of the car's history as a test mule and subsequent auction sale.
• 🗣️ The reviewer emphasizes the raw, old-school feeling of the 13-14 GT500, contrasting it with the more accessible speed of modern Coyote Mustangs.
