2019 Lebanon Ford Performance Twin-Turbo Mustang GT Preview & Buyer's Guide

Lebanon Ford Performance unveils a twin-turbo package offering insane horsepower at basement pricing.

Lebanon Ford Performance has long offered their "Pick Your Power for $39,995" series of supercharger upgrades for the Ford Mustang, with a choice of up to 800 horsepower depending on the level of modifications. Now, LFP adds a bolt-on twin-turbo package to the mix, with the resultant Street Sleeper capable of power in excess of 1,000 horses—all at the same sub-$40,000 price tag.

Exterior Styling

The entire purpose of the Lebanon Ford Performance package is to turn the 2019 Mustang GT into one of the best sleepers on the market. Zero exterior modifications are bolted onto the car, which retains a completely stock look down to its factory GT badging. This is no Shelby GT350R or GT500 with massive wings, racing stripes, body kits, or Shelby logos—making significant changes to the exterior would be completely against the point.

Still, there's no denying that the current Mustang generation is overall an aggressively styled design, perhaps the best since the first years of the model's long reign as America's premier pony. The exterior returns to the bold aggression of the earliest generation, with a long hood, aggressive haunches, and a low roofline.

Drivetrain & Mechanicals

The heart and soul of the LFP Street Sleeper Mustang is a pair of Hellion Power Systems turbochargers bolted on to increase power up to a claimed potential of 2,000 horses. The two turbos are 62mm water-cooled cast units supported by two Turbosmart Comp-Gate 40 wastegates, two Turbosmart VEE port bypass valves, and Ford's largest high-flow charged air intercooler. Fuel injectors are beefed up to a 56 lb/hr rating, and even more potent 1050X injectors can be had for more aggressive customers.

The upgrade package's layout helps to keep the system well below the radar, with both turbos mounted below the engine. The factory air box remains in its stock location, as well, so that even with the hood up, the modifications would require a pro to discern. LFP will install or ship the package with a base five pound wastegate spring which allows for around 7 PSI of boost and a claimed 700 horsepower at the wheels or roughly 800 at the crank.

A second wastegate spring rated at 7 pounds is also included to allow boost of up to 9-10 PSI, with resultant gains of another few hundred horses—here the possibility of 1,000 hp comes into play. Further options are also available from LFP, and the entire package is allegedly stout enough to handle up to 40 PSI, which would result in a Mustang GT with an estimated 2,000 horsepower.

The Street Sleeper's price tag includes the cost of a 2019 Ford Mustang GT equipped with a base six-speed manual transmission, which surprisingly, LFP seems to think won't require significant work to handle the potentially massive increases in power their product can produce. Perhaps owners opting to go the highest-performance route may opt to swap in the tranny from a GT350R or GT500 in hopes of extending their gearbox's lifetime. (For context, the Mustang GT's normally-aspirated Coyote V8 produces 460 horsepower and 420 lb-ft of torque.)


Interior & Tech

The LFP Street Sleeper package doesn't modify the interior of the car in any way, though most buyers will likely find it appealing to add a boost gauge somewhere to give accurate readouts of the system's capabilities. The Mustang GT from the factory, however, leaves little else that LFP could truly hope to improve. Stock options include Recaro seats, a digital driver's display cluster, touchscreen infotainment, and plenty of brushed-aluminum trim.

From the inside, passengers will feel the LFP Street Sleeper Mustang's power, and plenty of drivers may hope that nothing gives away the jolt of 1,000 horses planting everyone straight back into their seats.


Pricing & Buying

Despite the wild power claims, perhaps the most shocking aspect of LFP's Street Sleeper package is their decision to continue their longstanding "Pick Your Power for $39,995" marketing scheme. Previous iterations utilized Whipple, Procharger, and Roush superchargers for outputs of 700, 750, and 800 horsepower. Given the identical sticker price, why anyone wouldn't opt for the Street Sleeper Twin-Turbo variant is simply a mystery. Of course, the thought of a limited-edition Bullitt Mustang (which ships with similar engine specs as the GT) with a pair of turbos bolted on sounds pretty incredible, as well.


LFP's Street Sleeper Mustang has beaten the next Shelby GT500 to the market by at least a full year, while its lack of track-specific modifications makes it less of a competitor to the GT350R, either. Rather, LFP clearly has their sights set on Dodge's Challenger and Charger Hellcats in Redeye and Demon trim, as well as Chevrolet's Camaro ZL1 (not to mention Hennessey Performance's wild Exorcist Camaro). But with Redeyes, Demons, and Exorcists starting at over $70,000, LFP's sub-$40,000 all-in price tag certainly places their Street Sleeper in a league of its own.
