Lethal Performance 2020 Shelby GT500: Fit for a King

Lethal Performance 2020 Shelby GT500: Fit for a King


The Mustang King's chariot has arrived and she is GLORIOUS.
Check back here often for continuous updates on the progress of our 2020 Shelby GT500 Carbon Fiber Track Pack car. We'll be posting track times, modifications, dyno numbers & much more. We have some big plans for this car but, like our previous projects, we'll take the modifications step by step from bolt ons to a complete supercharger replacement (hellooooo 3.8L Whipple Supercharger!). Follow on our journey here and across our social media. It's going to be quite an adventure...


Here's what you can find below (click to jump ahead to that section):

  • The Wait: From ordering to receiving, it was a hot minute.
  • The Arrival: Donuts, burnouts, old man Jared & more from the dealership lot.
  • First Photos: Some snaps from the team of the car before we get to work on it. 
  • Drive & Discuss: Ride along with Jared as he goes over the car.
  • First Track Visit: Bone stock 1/4 mile runs
  • Stock Dyno: Bone stock numbers for the baseline
  • The Build: 3.8L Whipple, longtubes & fuel system installation


Looking for current numbers? Check this out. We'll update it with new numbers when we get them so keep it bookmarked!





Ford put out the initial teaser for the new new Shelby GT500 in the beginning of 2018, marketing it as a 2019 model. We were excited, to say the least, having owned just about every generation of SVT/Shelby vehicles before this. What we didn't know at the time was that we wouldn't get the car for TWO YEARS. TWO LONG IMPATIENT YEARS (luckily we had Project Goldmember to keep us busy).



We placed our order with Phillip Weikert of Weikert Ford in June of 2019 the same day the order banks opened up. Fortunately Weikert Ford had secured a golden ticket for the model we wanted: the Carbon Fiber Track Pack. BAZINGA. Unfortunately we didn't know ordering the majestic CFTP would set us back even more time due to the harsh winters of Michigan and Ford not wanting those special rubbers sitting in the icy wilderness that is Michigan (I'm being sarcastic....or am I?). 

Flash forward to March of 2020 and we get the notification that our car has entered PRODUCTION. Fireworks go off, bells ring and we are celebrating here at Lethal Performance, incredibly anxious to get the car. But then the Coronavirus pandemic reared its ugly head and Ford halted all productions... womp womp. 

Now we're in July of 2020 and the time has come: our car has arrived at Weikert Ford and is ready for us to take delivery!

We packed up the camera gear and some extra outfits and headed over to Weikert Ford to pick up our new 2020 Shelby GT500. We lucked out and were joined by Ford racing driver & test engineer Billy Johnson, who was picking up another beautiful Carbon Track Pack car that day. 



In true #teamlethal fashion, we couldn't just "pick up" the car so Phillip had the dealer lot cleared and we handed Billy Johnson the keys to give us some donuts for lunch. Oh and a healthy burnout departure from the dealer lot, too, joined by The Mustang King himself. 



The car is definitely a beast, a blast and it will only get better as we get to start playing with it. Like we did with our 2018 Mustang GT, Project Goldmember, we plan to document every step of the way right here and across our social media platforms (speaking of which, have you followed the King himself on Twitter yet?).

Now that we had the car, we set out to get some good photos of it before we started messing it up.... I mean modding it. We hit up a few spots and snapped some shots. Even in stock form it's no doubt that this is one of the best looking Mustangs EVER (fight me).

Sure the 2020 SHelby GT500 LOOKS good, but how does it feel driving it? Take a ride with Jared (aka The Mustang King) as he cruises around [Mexico] in our 2020 GT500 and goes over the different driving & exhaust modes. He may even punch it a few times...Maybe.

We took our new 2020 Shelby GT500 to the track BONE STOCK (right down to the Sport Cup 2 road race tires...) to get some baseline numbers. We fought crappy south FL humidity & heat (DA over 2600, grains over 130) as well as a track getting beat up by a bunch of street tires on a regular test & tune night but we managed to squeak out an 11.18 @ 123mph. We were hoping for a 10.xx but it just wasn't in the cards for us. The stock numbers don't mean much to us besides the baseline so after a couple of passes where traction was our biggest enemy, we decided to call it a night. Check out the video:

Exhaust! One of the first mods just about every Mustang owner does and we are no different! While there are a handful of great options for the exhaust on the 2020 Shelby GT500, we knew we wanted to rep our friends over at Corsa Performance. They didn't have any systems in production yet so we worked with them on this EXCLUSIVE catback setup for the 2020 Shelby GT500. CLICK HERE to check out the options for your own Shelby GT500.

This is what the Corsa Sport/Extreme Catback Exhaust (Corsa Touring/Sport mufflers paired with their Double Helix XX-pipe) sounds like on our 2020 Shelby GT500.



While it's all fun & games to jump on a dyno & see 4 digits off the bat, it's always nice to have some stock baselines for comparison. After all, wouldn't it be awesome to see HOW MUCH horsepower we GAINED? Obviously. Check it out:

Now that we know what it made stock and what it ran stock, it's time to jump right in! In the past, we've usually done gradual builds; starting with a cold air intake and tune, exhaust, pulley swap, etc. but with this car, we knew it was time to go big or go home so we jumped right in with the massive 3.8L Whipple Supercharger, Stainless Works longtube headers and a full Lethal Performance / Division X triple return style fuel system to support the power. CHeck out the videos below highlighting the installations of the different components:

STAY TUNED for future updates, including the dyno runs after the Whipple Installation... What do you think it will make??
