McLaren 720s Rebuild: Overcoming Challenges with Wiring and Component Placement

In this thrilling episode from the Mat Armstrong channel, the intrepid team embarks on a daring mission to resurrect a once-mighty McLaren 720s that suffered a devastating accident. With Richard Hammond doubting their ability to complete the task in time for Christmas, the pressure is on. But they are determined to prove him wrong.

The team kicks off the rebuild by meticulously transferring the good parts from the old tub to the new one, following the factory's precise procedures. It becomes clear that repairing the carbon damage is not an option, and a new approach is needed. Undeterred, they forge ahead, facing the challenges head-on.

The heart of the beast, the twin-turbo V8 engine, takes center stage. But before it can be installed, the fuel tank must find its rightful place. With careful precision, they maneuver the tank into position, ensuring that everything is in the correct order. It's a delicate dance, but they execute it flawlessly.

As they progress, they encounter a curious discovery. The original tub had a feature that pumped induction noise into the cabin, giving the driver an illusion of coolness. However, the new tub lacks this "cool hole," prompting a debate on whether to drill the holes or leave it as is. The team decides to table this discussion for later, as they have more pressing matters at hand.

With the engine ready, the team faces the challenge of fitting it into the tight confines of the McLaren's front end. It's a tight squeeze, but they manage to secure the engine in place with precision and finesse. The transmission, hoses, and other components are meticulously installed, ensuring everything is in its rightful place.

As the rebuild progresses, they encounter a significant hurdle. The McLaren is a left-hand drive model, and they need to switch everything over to a right-hand drive configuration. This involves cutting out a section of the left-hand drive tub and bonding it to the right-hand drive tub. It's a risky move, but they are confident it's the best solution.

With the front end successfully mounted, the team turns their attention to the intricate wiring and hydraulic lines. It's a complex puzzle, but they navigate through it with determination and skill. The dashboard, brake servo, and other crucial components fall into place, bringing them one step closer to their ultimate goal.

Despite a few remaining tasks, the team's progress is undeniable. The McLaren is slowly but surely coming back to life. The anticipation builds as they near the moment of truth—the first start of the engine. Will their efforts pay off? Only time will tell, but one thing is certain: this team is not backing down from a challenge. Stay tuned for the next thrilling installment of the McLaren rebuild saga.
