Noisy Boy 229HP Track Beast | Harley Build Overview 58 – Grudge Races

MHP 150 Race Bike Build #58 | Noisy Boy | 229HP & 191TQ Harley Drag Bike

Meet Noisy Boy, Moonshine Horsepower Bike Build #58—an all-out MHP 150 cubic inch race machine built to push the limits of Harley-Davidson performance.

In this episode, Jamie takes a deep dive into what makes this build one of the wildest bikes ever to leave the Moonshine Horsepower shop. From the engine combination and race-focused components to the tuning strategy behind its incredible power numbers, you’ll get an inside look at the technology and craftsmanship that created this 8,000+ RPM MHP monster.

The results speak for themselves: 229 horsepower and 191 lb-ft of torque on the dyno. This isn’t just another performance bagger—it’s a purpose-built race bike designed to dominate on the strip.

But we didn’t stop at the dyno.

After unveiling the build, we load up Noisy Boy and head to Hogs Gone Wild at Shadyside Dragway in Shelby, North Carolina, held June 12–13, 2026. There, the bike is thrown into the fire of grudge racing competition against some of the fastest Harley-Davidsons in the country. Will Noisy Boy back up the dyno numbers and take home the bragging rights?
