At the 2021 Mod Nationals an S550 struck a chord with my brain. It wasn’t the cowl hood, parachute, or wild paint scheme either. It was the rear wheels that seemed to peak my interest. The perfect drag stance alluded to the fact this car had more than just a solid rear axle swap under its beautiful body work. After seeing the car launch and make a 7-second pass, my suspicions were confirmed.
Joe Holt’s build at the 2021 Mod Nationals centered around a 98mm big single turbo. The new build changed everything from forced induction to paint scheme.

Transmitting the power from the extremely potent V8 is a Hughes Performance Powerglide with a custom converter. A carbon driveshaft heads towards the rear before the power finally reaches the RC Components double beadlock wheels. While all these new items are eye-catching, what one might not catch is all the hidden fabrication that went into Holt’s newest rendition.
As you can imagine, hood-exit turbos have not caught on in the mass production market. Holt took it upon himself to design and build the turbo kit.
