Peck Brothers Fire Up 200-Horsepower R1 Mini Trophy Truck

The Peck Brothers are no strangers to wild projects, but their latest endeavor is more than just a garage build; it is a race against time. But the pressure is mounting from all sides. With other creators popping up and calling them out, the brothers know they have a strict deadline to avoid being the last ones to cross the finish line with their 200-horsepower R1 monster.

A Game-Changing Tool

The biggest hurdle in the build has been the complex drive system, which demands precision parts that they could not buy off the shelf. To solve this, they acquired a massive industrial lathe from Liberty Machine Works. Cayleb Peck emphasized the magnitude of this acquisition for their shop capabilities. “That’s why this is like the one of the biggest things that’s ever happened for Peck Brothers.” However, bringing industrial machinery into the garage comes with its own set of risks. Alex Peck noted the danger involved with the powerful new tool. “Somebody’s going to end up getting an arm cut off in this thing.”

Engineering The 200-Horsepower R1 Drive System

With the lathe up and running, the team tackled the drive system, which uses a series of jackshafts and chains to transfer power. They fabricated a custom hub by combining a bored-out Ford Super Duty axle shaft with a sprocket housing. The fabrication had to be flawless to handle the immense speed of the chain drive.

Firing Up The Engine

While the mechanicals were being sorted, other parts of the build finally came together. Cayleb fabricated a custom stainless steel exhaust system, carefully tying in the cylinders to match the factory firing order. He explained his methodology regarding the header design. “I researched the firing order of this motor, and I tied in one and four and then tied in three and two.” The wiring was simplified using a switch panel, and by the end of the video, they successfully fired up the engine with its new exhaust and verified that the drive system was spinning the axle.

The Mini Trophy Truck Comes To Life

The project has officially moved from a pile of parts to a functional vehicle. Seeing the chains spin and hearing the engine fire up proves that the drive system is a reality. Cayleb expressed his relief at the functional mechanism after weeks of work. “I can’t believe we actually pulled that drive system off.” The Peck Brothers have successfully built a chassis that can handle the brute force of a 200-horsepower R1 engine, and now the race is on to finish the bodywork and get it in the dirt.
