2013 Ford Taurus Sho Top Speed – Performance Limits And Tuning
The 2013 Ford Taurus SHO is electronically limited to a top speed of 133 mph from the factory, primarily to protect the drivetrain and ensure tire safety. While the twin-turbo EcoBoost engine has the raw power to exceed 150 mph, reaching those heights requires specific hardware upgrades and an aftermarket engine tune.
Do you remember the first time you stepped on the gas in a Super High Output (SHO) Taurus? That immediate surge of twin-turbo torque is addictive, making it easy to wonder exactly where the needle stops climbing.
If you are looking to understand the 2013 ford taurus sho top speed, you likely want to know what is holding the car back and how to maximize its potential safely. In this guide, we will break down the mechanical limiters, the impact of the Performance Package, and the vital maintenance steps every SHO owner needs to follow.
We are going to look at why Ford chose that specific 133 mph limit and what actually happens when you decide to push this heavy-duty sleeper to its absolute brink. Whether you are a weekend DIYer or a track enthusiast, understanding these limits is the first step toward better performance.
Understanding the 2013 ford taurus sho top speed and Governor Limits
When we talk about the 2013 ford taurus sho top speed, we have to distinguish between “drag limited” and “electronically limited.” From the factory, Ford installs a speed governor that cuts fuel or adjusts the throttle once the car hits 133 mph.
This limit is not because the engine lacks “grunt,” as the 3.5L EcoBoost is a powerhouse. Instead, Ford engineers set this limit based on the speed rating of the factory tires and the heat tolerance of the All-Wheel Drive (AWD) system.
Most standard SHOs came equipped with V-rated tires, which are safe up to 149 mph. By setting the car to 133 mph, Ford builds in a safety buffer for sustained high-speed driving.
The Role of the Engine Control Unit (ECU)
The ECU acts as the brain of your Taurus, monitoring everything from boost pressure to wheel speed. When the sensors detect the car is approaching the 133 mph mark, the ECU intervenes to prevent further acceleration.
For many owners, this feels like a “wall” that the car hits, even though the engine still has plenty of RPMs left in fifth and sixth gear. Removing this wall requires an aftermarket flash tune, which we will discuss later.
It is important to remember that the ECU also manages heat. At high speeds, the turbos generate immense heat, and the computer may pull timing to protect the cylinder heads and pistons.
The 3.5L EcoBoost: The Heart of the SHO
The 2013 model year brought several refinements to the Taurus, but the star of the show remained the 3.5-liter twin-turbocharged EcoBoost V6. This engine produces 365 horsepower and 350 lb-ft of torque right out of the box.
What makes this engine special for high-speed runs is the flat torque curve. Unlike naturally aspirated engines that need to scream at high RPMs, the SHO provides maximum torque as low as 1,500 RPM.
This low-end power helps the heavy sedan (weighing nearly 4,400 pounds) overcome aerodynamic drag. As you approach the 2013 ford taurus sho top speed, drag becomes your biggest enemy, requiring more horsepower to push through the air.
Twin-Turbocharging Efficiency
The two small turbochargers are designed for quick response rather than massive top-end flow. This means they provide excellent “stoplight-to-stoplight” speed but can run out of breath at very high velocities.
If you plan on pushing past the factory limits, upgrading the intercooler is one of the best moves you can make. A heat-soaked intercooler will kill your top-end performance faster than almost any other factor.
Keep an eye on your boost levels using an OBD-II scanner or an auxiliary gauge. If the car feels sluggish during a high-speed pull, it is likely the ECU pulling power due to high intake air temperatures (IATs).
The SHO Performance Package: Does it Change the Top End?
Many enthusiasts seek out the “Performance Package” (PP) when buying a 2013 SHO. This package adds several track-focused upgrades, including a different final drive ratio and enhanced cooling.
Interestingly, the Performance Package does not actually increase the 2013 ford taurus sho top speed limit. In fact, because it uses a shorter 3.16:1 gear ratio (compared to the standard 2.77:1), the engine runs at higher RPMs at cruising speeds.
While the PP car accelerates faster and handles better, it is still bound by the same 133 mph electronic governor. However, the hardware included in this package makes the car much safer to drive at high speeds.
Key Upgrades in the Performance Package
- Upgraded Cooling: Includes a high-capacity radiator and an oil cooler to manage engine temps.
- Better Braking: Larger front rotors and heavy-duty brake pads to combat brake fade.
- Alcantara Steering Wheel: Provides better grip for the driver during high-speed maneuvers.
- Track Mode: Calibrates the Electronic Stability Control (ESC) to be less intrusive.
If you own a non-PP car, you can still reach the same top speeds, but you must be much more careful about transmission fluid temperatures. The PP’s additional cooling is a lifesaver for the PTU and gearbox.
Critical Maintenance for High-Speed Reliability
Before you even think about testing the 2013 ford taurus sho top speed, you must ensure your car is mechanically sound. These cars are heavy and put immense stress on their components.
The most notorious failure point on the 2013 SHO is the Power Take-Off Unit (PTU). This is the gearbox that sends power to the rear wheels, and it is known for cooking its own fluid.
If the PTU fluid breaks down, it turns into a thick sludge, leading to gear failure. I recommend changing the PTU fluid every 30,000 miles, even though Ford originally called it a “lifetime” fluid.
Tires and Alignment
At 130 mph, a small vibration becomes a violent shake. Ensure your tires are balanced and have a speed rating of at least “V” or “Y.” Check for any sidewall bulges or uneven wear.
- Inspect the inner tie rods and control arm bushings for any play.
- Ensure your tire pressure is set to the manufacturer’s specification for high-load driving.
- Get a professional 4-wheel alignment to ensure the car tracks straight at high velocity.
Stopping is just as important as going. Check your brake fluid; if it looks like maple syrup, it is time for a flush. High-speed braking generates enough heat to boil old, moisture-ridden fluid, leading to a “soft” pedal.
Aerodynamics and Stability at 130+ MPH
The Taurus is a large car, often described as a “rolling brick” by some enthusiasts. However, the 2013 SHO features subtle aerodynamic tweaks to help it cut through the air.
The rear spoiler and front air dam are not just for looks; they help manage downforce and reduce lift. At high speeds, lift can make the steering feel light and “floaty,” which is the last thing you want.
If you have modified your car with aftermarket body kits, ensure they are securely fastened. The air pressure at 133 mph is strong enough to rip off poorly installed splitters or undertrays.
Managing Underbody Airflow
The plastic undertray beneath the engine plays a huge role in aerodynamics and cooling. It creates a low-pressure zone that helps pull hot air out of the engine bay.
Many DIYers forget to reinstall this tray after an oil change. If yours is missing or dragging, replace it. It keeps the front end planted and protects sensitive components from road debris at high speeds.
Modifying for More: Removing the Speed Limiter
So, what if 133 mph isn’t enough? For those taking their SHO to a closed-course runway or a track, the 2013 ford taurus sho top speed can be unlocked using a handheld tuner.
Companies like Livernois Motorsports or SCT offer tunes that recalibrate the ECU. These tunes can raise the speed limiter to 150 mph or remove it entirely, allowing the car to reach its mechanical limit.
With a Stage 1 or Stage 2 tune, a 2013 SHO can realistically hit 160 mph, provided you have enough road. However, doing this without upgrading your tires and cooling system is extremely dangerous.
Hardware Requirements for 150+ MPH
If you plan to live in the high-speed lane, you need to move beyond simple software changes. Consider the following hardware upgrades:
- Three-Bar MAP Sensor: Allows the ECU to accurately monitor higher boost levels.
- Lowered Suspension: Reducing ride height lowers the center of gravity and improves high-speed stability.
- Performance Exhaust: A 2.5-inch or 3-inch cat-back system reduces backpressure, helping the turbos breathe at high RPMs.
- Upgraded PTU Cooler: Essential for protecting the AWD system during sustained high-speed runs.
Always remember that as speed increases, the margin for error shrinks. A mechanical failure at 60 mph is a bad day; a mechanical failure at 150 mph is a catastrophic event.
Frequently Asked Questions About 2013 ford taurus sho top speed
Is the 2013 Ford Taurus SHO faster than a Police Interceptor?
The 2013 Taurus SHO and the Police Interceptor Sedan (AWD EcoBoost model) share the same engine. However, the Police Interceptor often has a higher factory speed limiter (usually around 148 mph) and more robust cooling systems compared to a base SHO.
Can I remove the speed limiter without a tune?
No, the speed limiter is hard-coded into the ECU software. There is no “wire to snip” or simple fuse to pull. You must use a professional tuning device to modify the software parameters.
How does the AWD system handle top-speed runs?
The AWD system in the SHO is “on-demand.” At high speeds on a straight road, it typically sends most power to the front wheels to reduce friction. However, the PTU remains spinning and generates significant heat, making fluid maintenance vital.
What are the best tires for a 2013 Ford Taurus SHO?
For high-speed stability, look for “Y-rated” tires like the Michelin Pilot Sport 4S or Continental ExtremeContact DWS06. These provide excellent grip and are rated for speeds up to 186 mph.
Final Thoughts on the SHO’s Performance
The 2013 ford taurus sho top speed is a testament to Ford’s balance of performance and safety. While the 133 mph limit might feel restrictive to some, it exists to ensure the car remains reliable for hundreds of thousands of miles.
If you choose to push past these limits, do so with respect for the machine. Prioritize your maintenance—especially that PTU fluid—and never compromise on tire quality. The SHO is a fantastic sleeper that can surprise much more expensive sports cars, but it requires an attentive owner to stay at its best.
Take care of your EcoBoost, keep your cooling system in check, and always drive within your skill level. Whether you are keeping it stock or building a 500-horsepower monster, stay safe and enjoy the ride!
