Everyone knows that our main passion here at Lethal Performance is Mustangs but we've also been known to mess around with some trucks and recently we added one to the #lethalfleet...
Meet our 2021 Ford F150! This Sport model is, well, sporting a 5.0L Coyote engine with a 4x4 drivetrain and we are going to put it to WORK. Well, on the drag strip.

Before we get started, here's a chart of our current track times, dyno numbers & associated mod list for our 2021 Ford F150:
OK, onto the build...
We picked up the truck in April 2021 from our good friends over at Weikert Ford in Lake Wales, FL. While there, we even got to take a cruise in a new Mach E as well as the new Bronco Sport. Check out our initial F150 review:


IT'S FINALLY LOWERED!

SO HOT, right? We think so.
We can't WAIT to get the Weld Ventura 6 wheels on wrapped in some Mickey Thompson tires and hit the track for some baseline numbers.
After that, it's WHIPPLE TIME!
Houston, we have a Whipple!
It just so happens that our good friends over at Whipple sent us one of their first 2021 F150 Gen 5 3.0L Stage 2 Complete Supercharger Kits! Let’s take a look…
The Whipple Supercharger kit for the 2021 For F150 5.0L is a NEW Gen 5 3.0L design. It maintains their latest “upside down” technology, where there intercooler sits above the rotors and air flows up through the intercooler and then down into the runners for maximum efficiency.

UPR Catch Can
We headed over to UPR Products to meet up with Steve, aka @thecatchcanman, so we could help him develop the new UPR Products catch can setup for the 2021+ Ford F150. Check it out:

TO THE TRACK: Baseline Runs
We took our 2021 Ford F150 out to Palm Beach International Raceway to get some baseline numbers. Unfortunately FL weather is never great for racing in July, and with a DA of 2676 ft, 149.7 water grains and 75% humidity it definitely wasn't ideal for either the truck or us. It was HOT.
Now that the baseline runs are done, we're ready to install the Gen 3 5.0L Whipple Supercharger on the truck and can't wait to see what a difference it will make!
WHIPPLE INSTALL!
We dropped the 2021 F150 off at our neighbors' shop, WBA Performance, to have the 3.0L Gen 5 Whipple Supercharger kit installed. Check it out:
TRACK RUNS: This time, with the Whipple...
We took our recently Whipple-charged 2021 F150 out to the track for some testing. While weather wasn't ideal (DA 2249 ft | 80% hum | 131 gr | 86°) we clicked off a nice pass! This is on stock wheels & tires, too.
Here's the (oh so extensive) mod list:
3.0L Whipple Supercharger (Complete Kit)
VAS 3/5 Lowering Kit (w/ ViKing shocks & struts)
Stock tires & wheels
Stock exhaust
93 Octane
Now we get to start shaving some numbers off that time... #whippletheworld
OH, you wanna know what power it makes?
We tossed the F150 on the rollers to see just how much it makes over at Palm Beach Dyno. We aren't upset at all with the results!!
Here's the dyno sheet:
WHEW! Almost 300rwhp increase...#teamwhipple
Turning it UP: Adding Stainless Works exhaust & Circle D converter...LET'S GOOO!
We took our 2021 Whipple-powered F150 to the track and managed to set a new record. Now we want to kick it up yet another notch! So here we installed full Stainless Works exhaust, a Circle D torque converter, and some sticky meats wrapped on Weld drag wheels.
NEW BEST: Hitting the track with the new converter & exhaust
We took all 3 vehicles, the 2020 Shelby GT500, the Mach E GT and of course the Whipple supercharged 2021 F150 to the track to see if we can get some new personal bests. Previously the truck went 11.87 but since then we added a new Circle D converter and some Stainless Works exhaust... did it help? You betcha...
INCHING CLOSER: The hunt for 10s...
For the end of the year, we had our employee party at the track because, why not? Most of our employees got new personal bests... including Jared in the F150! We are so close to 10s we can feel it!!
