Beneath the hood lurks a big and nasty 9.0-liter twin-turbocharged Mercury Marine boat engine, good for 1650 hp and mated to a Tremec six-speed manual. And nobody will mistake the Tantrum for just another janky hotrod. The Tantrum’s interior is far beyond anything offered from the factory, and paired with the attention to detail everywhere else, it’s easy to imagine it as one hell of a daily driver.
You just have to be very careful with the throttle. Watch until the end of the video to see it disappear into a cloud of tire smoke. And noise. Lots of noise.
