Take a ride in the "BlueBonic Plague", the original Aircoled Technology Test Vehicle!
Watch this video to experience the thrill of a 235HP, 3 Liter MassIVe daily driver engine. Running on pump gas, the engine provided excellent drive-ability while attaining better than 25 MPG for its 14,000 mile stent in our test vehicle.
Pain and Endurance... Cross Country expeditions prove our technology in adverse conditions and operating environments.
In May of 2006 Jake Raby and Bill Kanz set off on a 3,450 mile trip across America to test out the "Type 4 Torquer" engine created by Aircooled Technology and featured in the "Hot VWs" article bearing the same name that spanned from March to Sept 2006. (engine pictured above left)

Own a Porsche 914? Want it to haul ass without the weight and complexity of an engine conversion????
Watch our videos that illustrate what a 2.4L MassIVe Type 4 engine can do when installed into a dual purpose Porsche 914 for autocross and track events. We even offer a street legal, "pump gas" version of this power plant, making equal power!
Remember, this is the same engine... same car... same driver... but two different styles of track events. This is a true "Dual Purpose" engine. Listen to it scream!
