The Heart of the Beast: The 5.2L Voodoo V8 Engine
The centerpiece of this vehicle is undoubtedly the 5.2-liter Voodoo V8 engine. Unlike standard Mustang engines, this powerplant utilizes a flat-plane crankshaft, which allows it to rev to a staggering 8,250 RPM. This design choice creates a unique exhaust note and improves high-end breathing.
The engine produces 526 horsepower and 429 lb-ft of torque. While these numbers are impressive, the way the power is delivered is what truly sets it apart. The engine features a 12.0:1 compression ratio and uses plasma wire arc liners instead of traditional heavy iron sleeves to save weight and improve heat transfer.
Advanced Oiling and Cooling Systems
High-revving engines generate immense heat, especially during extended track sessions. The GT350R comes equipped with an air-to-oil cooler to maintain optimal oil temperature. This is critical because the Voodoo engine is known to consume oil during spirited driving, a trait common in high-performance engines.
Ford also included a dedicated transmission cooler and a differential cooler as standard equipment for the 2017 model year. These systems ensure that the Tremec TR-3160 six-speed manual transmission and the Torsen limited-slip differential remain within safe operating temperatures under heavy load.
Air Induction and Exhaust Flow
The Voodoo engine breathes through an 87mm throttle body and a high-flow intake manifold. The exhaust system features a dual-mode active exhaust, allowing the driver to choose between a “Normal” mode for the street and a “Sport” mode that opens the valves for maximum flow and sound.
If you are performing your own maintenance, always check the exhaust hangers and valve actuators. Heat cycles on the track can cause these components to loosen or bind over time. A quick spray of high-temp lubricant on the valve pivots can prevent annoying rattles.
2017 ford mustang shelby gt350r specs: Chassis and Handling
The chassis is where the GT350R separates itself from the standard GT350. When examining the 2017 ford mustang shelby gt350r specs, the most striking feature is the use of carbon fiber wheels. These wheels reduce unsprung weight by approximately 60 pounds compared to aluminum alternatives.
Reducing unsprung mass allows the suspension to react faster to road imperfections and steering inputs. The GT350R also features a lower ride height and a more aggressive alignment setup from the factory. This ensures the Michelin Pilot Sport Cup 2 tires maintain a massive contact patch through corners.
MagneRide Damping Technology
The suspension utilizes Ford’s MagneRide Damping System, which uses magnetic fluid to adjust shock stiffness in real-time. This system monitors road conditions and driver input 1,000 times per second. It provides a firm, composed ride on the track while remaining surprisingly compliant on the street.
For DIYers, it is important to inspect the MagneRide sensors located at each corner of the car. If a sensor arm becomes bent or disconnected, the system will default to a stiff “fail-safe” mode. Regularly cleaning road debris away from these sensors will ensure consistent handling performance.
Braking Power and Heat Management
Stopping power is provided by a massive Brembo braking system. The front features 15.5-inch two-piece cross-drilled rotors clamped by six-piston fixed calipers. The rear uses 14.9-inch rotors with four-piston calipers, providing exceptional balance and fade resistance.
Always use a high-quality, high-boiling-point brake fluid like DOT 4 if you plan on tracking the car. The GT350R also includes dedicated brake cooling ducts. Ensure these ducts are clear of leaves or track rubber to maintain consistent pedal feel during heavy braking zones.
Aerodynamics and Weight Reduction Strategies
The “R” in GT350R stands for more than just racing; it stands for radical weight savings. Ford engineers removed the rear seat, the air conditioning system, and the audio system to shed pounds. While some owners opt to add the “Electronics Package” back in, the base R is a minimalist masterpiece.
This weight reduction brings the curb weight down to approximately 3,650 pounds. This may still seem heavy for a track car, but the balance is nearly 53/47 front-to-rear. This distribution helps the car rotate predictably during mid-corner transitions.
Functional Aerodynamic Components
Aerodynamics are a key part of the 2017 ford mustang shelby gt350r specs package. The car features a massive carbon fiber rear wing that creates significant downforce at high speeds. Up front, a larger front splitter balances the car, preventing front-end lift during high-speed cornering.
When driving on the street, be extremely mindful of the front splitter. It sits very low and is prone to scraping on driveways or speed bumps. Many owners install “Scrape Armor” or similar protective plates to prevent damage to the expensive carbon fiber components.
The Importance of the Underbody Shield
The GT350R uses a specialized belly pan to smooth out airflow under the car. This part is crucial for both cooling and stability. If you are doing an oil change, ensure all the fasteners are secured tightly when re-installing the shield. A loose belly pan can flap at high speeds, causing noise and reduced downforce.
Drivetrain and Transmission Specifics
Power is sent to the rear wheels through a Tremec TR-3160 six-speed manual transmission. This gearbox is designed for high-RPM shifts and features a dual-mass flywheel to help dampen vibrations from the flat-plane crank engine. The shift action is precise, with short throws that encourage aggressive driving.
The rear end houses a 3.73:1 Torsen limited-slip differential. This unit is excellent at putting power down coming out of corners without the “chatter” often associated with traditional clutch-type differentials. It is a robust unit, but it requires specific 75W-85 gear oil with friction modifiers.
Clutch and Flywheel Maintenance
The factory clutch is a twin-disc design, which provides a high torque capacity while maintaining a relatively light pedal feel. If you notice any slipping or a change in engagement height, it may be time for an inspection. Because of the high-revving nature of the Voodoo, the clutch takes a significant amount of abuse during launches.
When replacing the clutch, many enthusiasts consider a lightweight single-mass flywheel. While this can improve engine response, it often introduces significant “gear rattle” at idle. Stick with the OEM dual-mass unit if you value a refined driving experience on the street.
Interior Ergonomics and Driver Interface
Inside the cabin, the GT350R is focused entirely on the driver. The Recaro sport seats are upholstered in Alcantara and provide massive lateral support to keep you planted during high-G maneuvers. The steering wheel is also wrapped in Alcantara, offering a superior grip even if your hands are sweaty.
The gauge cluster includes a unique “Performance Shift Light” projected onto the windshield. This allows you to keep your eyes on the track while knowing exactly when to shift. You can customize the light patterns to suit your preference, whether you want a sequential bar or a flashing warning.
The Lack of Sound Deadening
To save weight, Ford removed much of the sound deadening found in the standard Mustang. This means you will hear every pebble hitting the wheel wells and every mechanical whine from the drivetrain. While this adds to the mechanical connection, it can be tiring on long highway trips.
If you are a DIYer looking to improve comfort, resist the urge to add heavy sound-deadening mats. Instead, consider using high-quality earplugs for long transits to the track. Preserving the weight-saving mission of the GT350R is essential for maintaining its value and performance.
Common Maintenance and Track Prep Tips
Owning a high-performance vehicle like this requires a more proactive maintenance schedule. Because the Voodoo engine is a “hand-built” unit, you should check your oil level at every fuel fill-up. It is not uncommon for these engines to use a quart of oil every 500 to 1,000 miles during aggressive use.
Using the correct oil is non-negotiable. Ford specifies 5W-50 full synthetic oil that meets the WSS-M2C931-C standard. This weight provides the necessary protection for the high-speed bearings and valve train components at 8,000+ RPM.
Pre-Track Inspection Checklist
Before heading to the track, perform a thorough nut-and-bolt check of the suspension. Pay close attention to the caliper bolts and lug nuts. Remember that the carbon fiber wheels require a specific torque sequence and should never be tightened with an impact wrench. Use a high-quality torque wrench set to 150 lb-ft.
- Check Fluid Levels: Oil, coolant, brake fluid, and differential fluid.
- Inspect Tires: Look for cracks in the tread of the Cup 2 tires, especially if they have been stored in cold temperatures.
- Brake Pads: Ensure you have at least 50% pad life remaining before a full track day.
- Clean Radiators: Use compressed air to blow out any debris from the front cooling stacks.
Managing Heat Soak
After a hard session, never park the car and immediately pull the parking brake. This can cause the hot brake pads to “weld” to the rotors or warp them. Instead, perform a slow cool-down lap and park the car in gear on a level surface. Pop the hood to let the engine bay heat escape more efficiently.
