INSANE V12 Sound - Hand-Built Engine Roars to Life for the First Time - Aardema Braun

Witness the incredible journey behind one of the most ambitious home-built engine projects ever attempted—crafted by 84-year-old Pete Aardema and master engine builder Kevin Braun, this handmade 5.0L V12 engine is a true testament to old-school craftsmanship, modern ingenuity, and raw passion for mechanical engineering.

Over 2.5 years in the making, this custom V12 was designed, machined, and built entirely from scratch. It features highly modified Oldsmobile Aurora IndyCar heads, precision-cut to fit a one-of-a-kind V12 block. This monster is expected to rev up to an astonishing 12,000 RPM—and in this video, you’ll get to see it all.

What’s Inside This Video:
• Engine design, welding and fabrication process
• CNC machining and custom part creations
• Electronics and ECU programming
• The very first startup of the engine
• Dyno testing and horsepower tuning
This is more than just a build—it’s a legacy project, and a jaw-dropping tribute to the art of engine building.
