For longtime fans of Street Outlaws and No Prep Kings, the name Goliath is legendary. This was the car that Daddy Dave campaigned for years, making waves on the street and the track. A while back, he made the big decision to sell Goliath, and it found a new home—all the way in Brazil. Since then, it’s been going through some changes, and the latest upgrade has certainly caught our attention.

From ProCharger to Roots Blower
When Daddy Dave sold Goliath, it was running a Proline MH5 Hemi with a ProCharger setup—an absolute beast of a combination that pushed the car deep into the 3.70s in the eighth mile. That setup made serious horsepower and was a proven winner in No Prep Kings. However, now that the car is in Brazil, it’s undergone a major transformation.
Goliath is now sporting a Mike Janis-built Roots blower setup, replacing the ProCharger system. While we haven’t seen detailed photos of the engine bay yet, it’s highly likely that the car still has its Proline Hemi, but now it’s topped with a roots-style supercharger instead of a centrifugal blower.

A History of Power Changes
This isn’t the first time Goliath has gone through a powertrain evolution. Over the years, the car has been equipped with a variety of powerful setups, including:
A 632 cubic-inch nitrous motor
A Big Block Chevy ProCharger combination built by Scott and Dickie Parts Center
A ProCharged 481X
A Twin-Turbo 481X
A ProCharged Hemi
And now, a Roots Blown Hemi
Few cars have had such a diverse history of engine setups, and Goliath continues to evolve even after its time with Daddy Dave.
Will the Roots Blower Perform as Well?
Now, here’s the big question—will the Roots blower be as competitive as the ProCharger setup? On paper, the ProCharger, especially if it was the massive 1401 model that Daddy Dave used, is capable of making more power. It’s also more efficient than a Roots blower, which generates more heat and requires a lot of power to spin.

That said, there could be some reasons why this change makes sense for Goliath in Brazil. One of the biggest issues with ProChargers, especially in extreme racing conditions, is durability. Reports suggest that teams in Brazil were struggling with ProCharger failures, which might explain why they switched to a Roots blower—a setup known for being reliable and consistent.
Another possibility? This could just be a stepping stone toward a screw blower setup, which would be a serious performance upgrade.
A Mean New Look & Sound
Love it or hate it, there’s no denying that a big blower sticking out of the hood just looks badass. While some purists prefer a clean, smooth bodyline, there’s something special about the aggressive stance of a Roots or screw-blown setup. And if you’ve ever heard one in person, you know how insanely loud these cars are. That high-pitched, whiny scream of a Roots-blown Hemi is pure American horsepower at its finest.
So, while this latest chapter in Goliath’s history might not be what some fans expected, it’s definitely one worth watching. Will it dominate like it did with Daddy Dave? Time will tell. But one thing’s for sure—this car isn’t done making noise on the track just yet.
