Guntherwerks has developed a reputation for building the best, most coveted 993-based "reimagined" Porsches around. With GT3-like handling, eye-popping low curb weights, and massive power from their Rothsport engines they perform like few other air-cooled cars on the planet. Well now Gunther's got Turbo power. Their new Turbo "Tornado" variant packs a 750 HP 4.0L twin-turbo Rothsport engine and weighs only 2,670 lbs. This is a powertrain validation mule, so it's not finished. It has no interior, the body work isn't quite right, and it's got a cheap crappy wrap on it rather than gorgeous naked carbon. But Guntherwerks asked us to drive it for a week to give them some notes on the setup for the canyons, and we asked if we could film and share our thoughts with you. So here we go.
