How Much Power Has The Shelby GT500 Lost After 182,271 miles?

How much Power is lost after 182,217 miles? This Ford Mustang Shelby GT500 gives the Answer

This Mustang Shelby GT500 has seen a lot

It has 182,217 miles worth of stories to tell, but how does it fare performance-wise?

The 2012 GT500 boasted decent figures when new

550 hp and 510 lb/ft from a 5.4-liter supercharged V-8

With high-mileage cars, power-loss is to be expected

But the way it's been driven and maintained over the years is just as important

Power hits the rear axle through a Tremec 6060

For this drivetrain layout a 12-15% powertrain loss is a normal value

It seems the mighty V-8 is not tired even after 182,271 miles

On the first run it puts down 465 hp and 475 lb/ft to the wheels

However, the second run isn't as strong

Only 450 hp and 470 lb/ft to the wheels

The LMR team found a fault

A bad relay for the intercooler pump had to be replaced

The after-pull surpassed expectations

The last dyno run measured 486 hp and 486 lb/ft to the wheels

The old snake still has it

After calculating drivetrain loss, it appears no power has been lost even after 182,217 miles
