We've put together the perfect power package for your 2020-2023 SHELBY GT500.
The 2020+ GT500 is a masterpiece put together by Shelby American and the team at Ford Performance.
It is the pinnacle of American Muscle engineering made for the track... any track. In the 2020+ GT500 you'll find a very similar motor to the 5.2L VooDoo found in the Shelby GT350. Hand-built and strapped with a blower bigger than Ford's own EcoBoost engine, the 5.2L Predator engine makes a respectable 760hp which translates to about 670whp on 93 octane.
Now, while this may seem more than enough for some, we know there are many like us who like to ramp things up a notch without sacrificing ride quality or everything that makes your vehicle unique.
Well, we found and tested the best combination of parts to take your stock GT500 and turn it into a real Demon Killer.
Now, we've boosted and tuned many 5.0L Coyotes both on 93 and E85. You name it, ProCharger, Whipple, and even Kraftwerks supercharger system but none have come close to what this 2020+ GT500 made with our Parker Performance +2020 GT500 STAGE I and II packages!
Our STAGE I Package takes your already great GT500 and bumps those wheel-horsepower numbers to a whopping 745whp/623wtq on 93 octane! This is BY FAR the highest horsepower numbers we've ever safely pumped out of any vehicle running pump gas aside from that 1,000WHP Whipple-built Mustang GT we did a few years ago.
Now, if you thought THAT was enough power we'd say, "Yeah for 93", Let's pump some Fun-Juice in the tank and see what she can really make!
Our STAGE II Package takes things up to the next level. For those who have accessibility to E85, Your GT500 will be able to put out an impressive 824whp/666wtq. Talk about all-out power by just switching fuels. As impressive as that may seem, we still believe we can snatch more out of it with a smaller pulley.
This power was made using the SPE 2020+ GT500 PULLEY
found in our Parker Performance +2020 GT500 Pulley Down Package.
Our Parker Performance +2020 GT500 Stage I Package includes:
-Parker Performance +2020 GT500 Pulley Down Pack
-Injector Dynamics 1340cc Injector - 60mm Length - 14mm Grey Top - Blue Bottom Adaptor (Set of 8)
-HP Tuners RTD+ With 2020-2021 GT500 Custom Tune
-Your choice of the JLT 2020 Ford Mustang GT500 Big Air Intake Kit w/Red Oil Air Filter (No Tuning Required) or SPE +2020 GT500 Stage 1 Carbon Fiber Intake.
-Your choice of the ARH +2020 Ford Mustang GT500 1-7/8in x 3in Direct Connect w/Cats or the ARH 2020 Ford Mustang GT500 1-7/8in x 3in Long System w/ Cats
(This package is rated for 745whp/623wtq on 93 octane)
Our Parker Performance +2020 GT500 Stage II Package includes:
-Everything from our STAGE I but this time it's all wrapped up with a Lund Racing E85 custom tune putting out a whopping 824whp/666wtq.
Fun note: the +600wtq creeps in at 3,500RPMs.
The best thing about these packages is that very little has to change in order to make the power. CAI, Pulley, Injectors, Headers, a Tune, and Your GT500 still remains almost "stock" looking but definitely not making stock power. All in, about $6,000 in parts and you're riding around in a 900HP machine.
We will 100% recommend upgrading tires at this point.
You can pair these packages up with any cat-back system of you're liking, although, we found the stock system to be plenty sufficient in loudness and efficiency. But if interested here's a great list of best-selling GT500 Exhausts.
