Ford Performance, Roush Performance Unveil 5.0L Mustang, F-150 V-8 Supercharger | Ford Performance

Ford Performance and Roush Performance don’t put their names on aftermarket power numbers lightly, which is what makes this dealer-installed supercharger kit for the 2018 Mustang GT and F-150 worth paying attention to. The kit pushes the Mustang to 700 horsepower and the F-150 to 640, all while keeping the factory warranty fully intact. See exactly what Ford is backing and why it still matters for Coyote-powered owners.

Ford Performance rarely makes noise about horsepower it can’t back up on paper, and this announcement is a good example of exactly how far that restraint can be pushed before it becomes a real product. Most manufacturers keep their biggest power claims locked inside a low-volume halo model that most buyers will never actually own, order, or even see parked at a local dealership. A dealer-installed, factory-warrantied supercharger kit for the S550 Mustang GT is one thing — plenty of aftermarket companies build those without any blessing from Dearborn. A kit engineered jointly with Roush Performance that carries Ford’s own factory warranty, and that Ford is willing to put its badge on for both a sports car and a full-size pickup truck, is something else entirely. The numbers involved explain why this announcement got attention the moment it dropped, and why the comment section is still asking follow-up questions about it years later.

A Warranty-Backed Power Number Most Automakers Won’t Touch

The centerpiece of the announcement is a state-of-the-art supercharger kit built specifically for the 5.0-liter Coyote V8 shared by the 2018 Mustang GT and the 2018 F-150. In the Mustang application, the kit pushes output to 700 horsepower and 610 lb-ft of torque — a massive jump over the naturally aspirated GT’s factory rating, and numbers that put a dealer-warrantied Mustang GT within shouting distance of the far more expensive, flat-plane-crank GT350R, without the buyer having to void a single mile of manufacturer coverage to get there.

700 Horsepower, Still Under Ford’s Own Coverage

The F-150 application tells a different but equally significant story about where Ford Performance was willing to take this technology. Ford rates the supercharged truck at 640 horsepower and 600 lb-ft of torque, applied to a vehicle that most owners are using for towing, hauling, and daily work duty rather than the drag strip on weekends. Packaging that kind of power increase into a warrantied truck powertrain, rather than restricting it to just a low-volume halo sports car, signals how seriously Ford Performance and Roush were treating durability testing long before this kit ever reached a press release or a dealership order sheet.

Why the F-150 Application Is the Bigger Story

The “dealer installed and warrantied” language in the description is doing a lot of quiet work here, and it’s worth unpacking. Aftermarket supercharger kits have existed for the 5.0-liter Coyote engine for years from a wide range of third-party tuners. Installing one through a non-factory channel, however, typically voids the powertrain warranty outright and can complicate resale value, financing, or insurance down the road. A kit installed at the dealer level, under Ford’s own warranty umbrella from day one, removes that risk entirely for a buyer who wants serious power without gambling on aftermarket reliability — which is exactly the practical question one commenter raises when asking whether the kit is also compatible with an earlier 2016 Mustang GT.

What ‘Dealer Installed and Warrantied’ Actually Solves

Roush Performance’s involvement matters just as much as Ford’s own name on the box. Jack Roush’s operation carries decades of supercharger engineering and endurance racing pedigree behind it, and partnering directly with Ford Performance on a warrantied factory kit — rather than simply selling a standalone aftermarket unit through the usual channels — reflects a level of joint validation testing that most third-party supercharger kits never go through at all. That collaboration is what allowed Ford to put its name on the finished product with genuine confidence rather than a disclaimer.

Roush Performance’s Fingerprints on the Engineering

The timing of this release also sits at an interesting point in Mustang product history worth understanding. The GT350 and GT350R already existed by 2018 as Ford’s flat-plane-crank halo cars, built around a specialized 5.2-liter Voodoo engine rather than the standard Coyote. So a supercharged, dealer-warrantied GT wasn’t built to replace either of those cars — it was filling the gap for buyers who wanted serious, near-GT350R power without stepping up to the more track-focused, stripped-down GT350 platform, or for F-150 owners who wanted comparable power delivered to a truck bed instead of a coupe at all.

Where This Kit Fits Next to the GT350

One comment in the thread notes Dave Pericak’s departure from Ford Performance around this general period, a reminder that this release landed during a stretch of real leadership transition inside Ford’s performance division. Whatever came next organizationally, this kit’s core pitch to buyers stayed consistent from the day it was announced: factory-level confidence in nearly 700 horsepower, without anyone having to choose between real power and a real warranty.

A Release That Landed Mid-Transition at Ford Performance

For enthusiasts weighing the decision even now, the calculus hasn’t really changed since 2018. A warrantied supercharger kit costs more upfront than most standalone aftermarket units, but it removes the single biggest risk factor in forced-induction ownership — a blown engine with no manufacturer support to fall back on. That trade-off is precisely why a factory-backed announcement like this one still generates genuine engagement from Mustang and F-150 owners years after the video first went up, long after most product-reveal videos have been forgotten entirely.

Why the Warranty Trade-Off Still Matters Years Later

It’s also worth putting the Coyote engine itself in context, since it’s the common thread running through both applications in this announcement. Ford’s 5.0-liter Coyote V8, introduced for the 2011 Mustang GT and later shared across the F-150 lineup, was already a significant departure from the pushrod small-blocks that powered Mustangs for decades — a dual-overhead-cam, four-valve-per-cylinder design chasing both horsepower and modern emissions compliance at the same time. Bolting a supercharger onto that architecture and getting reliable, warrantied output all the way up to 700 horsepower required more than just strapping a blower on top; it meant re-engineering fuel delivery, cooling, and internal strength margins to survive the kind of daily use and towing duty Ford expected these vehicles to see for years, not just a dyno pull on a press day.
