In the latest episode from Rob Dahm's garage, the team dives headfirst into the intricate world of tuning a 12-rotor engine. Facing challenges like oil blowby and disparities in air-fuel ratios among the rotors, they navigate the complexities of high-performance engineering with grit and determination. Despite setbacks like damaged cylinder walls and boost creep, they push forward with relentless ambition, aiming to optimize fuel delivery and achieve peak performance.
With the engine roaring to life at 1100 horsepower and 920 ft-lbs of torque, Rob's project hits a new milestone, setting records and turning heads in the automotive world. Through meticulous tuning and calibration, the team uncovers the engine's true potential, overcoming misfires and power discrepancies along the way. Each dyno session brings them closer to unlocking the full power of this beastly machine, with torque curves and power figures painting a promising picture of what's to come.
But it's not all about raw power for Rob Dahm. Engaging fans in a unique merch launch tied to the engine's horsepower output adds a fun twist to the high-stakes world of performance tuning. Teasing plans to enhance the engine's sound and performance by firing all 12 rotors separately, Rob hints at a future filled with even more jaw-dropping feats and engineering marvels. And with a limited edition shirt celebrating the Cosworth XD program, the project's scope expands to encompass a diverse range of automotive passions and pursuits.
