The 2005 Saleen Mustang S281. A modern classic, already boasting impressive performance right off the showroom floor. But for some, like our reader TJ, that’s just not enough. He dreams of pushing his Saleen past the 700 horsepower mark, transforming it into a true tire-shredding monster. And let’s be honest, who can blame him?
This ambition presents a thrilling challenge, a deep dive into the world of high-performance modifications. In this article, we’ll explore the two paths TJ has laid out, analyzing the best parts, potential costs, and essential considerations to help him achieve his goal. Buckle up, because things are about to get interesting.
Supercharging Your Way to 700 HP: A Deep Dive
TJ’s first instinct is spot on – forced induction is the key to unlocking massive horsepower gains. His existing supercharger provides a solid foundation, but reaching 700 HP requires stepping up to a bigger, badder system.
The Kenne Bell 2.8L: Your Ticket to Supercharged Glory
The consensus among Mustang enthusiasts is clear: when it comes to supercharging these ponies, Kenne Bell reigns supreme. Their 2.8L supercharger is a popular choice for those seeking significant power increases without sacrificing low-end torque, a common drawback of larger superchargers. This beast can comfortably support 700 horsepower with the right supporting modifications.
Building a Foundation for Power: Essential Supporting Mods
Bolting on a massive supercharger without reinforcing your engine is a recipe for disaster. To handle 700 horsepower reliably, several key upgrades are essential:
- Forged Internals: Upgrading to forged pistons, connecting rods, and a crankshaft is crucial. These components are designed to withstand the immense stresses of high horsepower and boost pressures.
- Fuel System Overhaul: Your fuel system needs to keep up with the increased demand. Expect to upgrade your fuel injectors, fuel pump, and potentially even convert to a return-style fuel system for optimal fuel delivery.
- Exhaust System: A high-flow exhaust system, including long tube headers and a free-flowing cat-back, will help your engine breathe and maximize power gains.
- Cooling System: Keeping things cool is paramount. Upgrading your radiator, intercooler (if applicable), and cooling fan will prevent overheating and maintain optimal performance.
Expert Insight: A Word from Tuner X
“When modifying a car for this level of performance, it’s crucial to work with a reputable tuner,” advises Tuner X, a renowned Mustang performance specialist. “They can help you select the right components, calibrate your engine management system for optimal power and reliability, and ensure your car is running safely and efficiently.”
Engine Swap: Unleashing a Big Block Thunder
TJ’s second path involves a more radical approach: swapping out his 4.6L for a larger, more potent engine. While this option offers immense potential, it comes with its own set of considerations.
Engine Options: Finding the Perfect Fit
- Ford Racing Aluminator Crate Engines: These engines offer a compelling blend of power and reliability. The Aluminator 5.0 XS, for example, provides a significant power boost straight out of the box and can be further enhanced with a turbocharger or supercharger.
- Custom-Built Engines: For the ultimate in power and personalization, a custom-built engine is the way to go. Working with a reputable engine builder allows you to specify every detail, ensuring it perfectly matches your desired performance goals.
Turbocharging Your Beast: Taking it to the Next Level
While TJ initially leans towards supercharging, he mentions a fondness for turbochargers. Fortunately, both supercharging and turbocharging are viable options for his engine swap. Turbocharging generally offers greater peak power potential, while supercharging is known for its linear power delivery and instant throttle response.
The Cost of Power: Balancing Budget and Performance
Engine swaps are inherently more complex and expensive than supercharger upgrades. The cost of the engine itself is just the tip of the iceberg. You’ll need to factor in engine mounts, wiring harnesses, a new transmission (more on that below), and potentially even modifications to your engine bay to accommodate the larger powerplant.
Drivetrain and Suspension: Reinforcing the Backbone
Regardless of which path TJ chooses, upgrading his drivetrain and suspension is non-negotiable. 700+ horsepower puts immense stress on these components, and neglecting them will lead to broken parts and disappointment.
- Transmission: A heavy-duty transmission, such as the Tremec T-56 or TKO600, is a must-have for handling that much power. These transmissions are designed to withstand the rigors of high-horsepower applications and offer smooth, precise shifting.
- Clutch: A performance clutch and pressure plate are essential to transfer power to the wheels without slipping.
- Rear Differential: Upgrading to a stronger rear differential with a higher gear ratio will help put the power down effectively and improve acceleration.
- Suspension: A performance-oriented suspension setup, including stiffer springs, upgraded shocks, and stronger sway bars, will improve handling and stability, especially during hard acceleration and cornering.
Conclusion: A Journey of Power and Passion
Building a 700+ horsepower 2005 Saleen Mustang is an ambitious undertaking, but with careful planning, the right parts, and expert guidance, it’s an achievable dream. Whether TJ opts for a supercharger upgrade or a full-blown engine swap, he’s in for the ride of his life.
Remember, this article provides a starting point for exploration. Always consult with experienced mechanics and tuners to determine the best approach for your specific vehicle and power goals. And most importantly, enjoy the journey of transforming your Mustang into a true force to be reckoned with!
