Nitro Tech: Watch Rob Wendland Bring A Supercharger Back To Life

Esteemed NHRA nitro crew chief Rob Wendland has tuned many a Top Fuel Dragster and Funny Car in his career, so it’s safe to say he knows a thing or two about how a nitro-guzzling HEMI works. Fans don’t often get to see everything that goes into making a Top Fuel dragster capable of running over 300 mph, but Wendland is peeling that curtain back and shows us in this video what goes into rebuilding a Top Fueler’s supercharger.

A Top Fuel engine uses a roots-style 14:71 supercharger, which you can learn more about right here. These superchargers (along with the nitromethane fuel) are what makes it possible to generate over 10,000 horsepower, but as you can imagine that’s not an easy life to live. These superchargers need regular maintenance and repairs to their internal components so they can function properly each pass.

Most people will never get to see what the inside one of these superchargers looks like, so the tour that Wendland takes us on in the video is really fascinating. The supercharger in question has been wounded in battle and is in need of some serious repairs before it can be used again. Wendland shows us the entire process of tearing the supercharger down, diagnosing the issue, and making the necessary repairs for it to make boost again. Now, this video only shows the major steps and specialized equipment required to service one of these superchargers, but it’s still really cool to watch.

Make sure you watch the entire video to see every step Wendland takes to revive this precision boost-making machine.
