Watch This Four-Rotor All-Wheel-Drive RX-7 Shoot Fire Balls on a Dyno

This thing is the definition of insanity.

YouTuber Rob Dahm has spent the better part of the last four years building his dream car: An FD-generation Mazda RX-7 with a turbocharged four-rotor engine and all-wheel drive. He was recently able to get the car onto a dyno for tuning, and it looked like one hell of an event.

After maxing out his rental UHaul's trailer width to get to the dyno shop, Dahm first runs the car without turbo pressure to ensure the engine is working properly (it needed to be rebuilt after a previous run caused aluminum to enter the block assembly). Later on, the turbo and all-wheel-drive systems are connected, and all hell breaks loose. Day one of this dyno session (above) was the first time the car has properly run on boost, and the team had barely scratched the surface of what the car is capable of, posting up numbers over 500 horsepower. On day two, his car was able to reach 1000 horsepower:

Building a four-rotor vehicle of any kind is no small task. Dahm has sunk a massive amount of time and money into this build so far. Dahm told HP Academy in a recent interview his goal is to push the car past 1600 horsepower, and with that 102-millimeter turbo, it's certainly possible. We can't wait to see this thing on the move.
