Mike Harrah’s V24-71 Detroit Diesel “Big Mike” truly is a thing of beauty.
Mike Harrah is a pretty awesome guy who has done a ton of great things (you can read more about him HERE). But what I think might be the best thing he has done thus far is created “Big Mike”. This beast is a V24-71 Detroit Diesel with twelve BDS blowers, 36 butterflies, and 24 cylinders thanks to two V12 Detroit Diesel engines matted together with splined cranks. “Big Mike” dynos at 3,424hp, and I’m guessing at least 5,000 lb/ft of torque. That’s over eight times as much power as your typical semi truck makes. So now this is installed on an Allison transmission inside a custom 359 Peterbilt truck with a giant 40-foot long custom chassis to hold it all together.
