Welp, back to the drawing board!
Part of building any kind of hardcore, high-powered drag monster involves quite a bit of dyno testing and tuning. Usually there are some unexpected hiccups throughout the process, but these are usually easily fixed.
Well, this twin-turbocharged Ford Mustang was on the dyno for some testing and things quickly went south. Like really, really south where there are no easy fixes.
While making a dyno run, a piston broke and the valve cover breather shot out due to the incredible amount of pressure, according to the YouTube video uploader, HostileGSX.
That’ll be fun to repair!
