DDMWorks Twincharged Ariel Atom

Boost: (n) 1) hike, increase; 2) the act of shoving ridiculous amounts of air into an engine to produce hoonage of epic proportions.

That's the quickest way to describe the DDMWorks Twincharged Ariel Atom, a 430-horsepower screamer that uses both a turbocharger and a supercharger to extract maximum attack from the tiny open-framed roadster. At just 1,375 pounds, the modified Atom is good for a power-to-weight ratio of just 3.4 pounds per horsepower.

Best of all, the kit isn't ridiculously expensive. At $6,500, the basic system is about the same price as many aftermarket single-turbo production car installs. And we don't have to tell you that twice the number of forced induction systems means at least twice the fun.

Pairing a Borg-Warner S256 turbo with a Harrop HTV1320-LSJ supercharger that uses an Eaton Twin Vortices Series screw setup like the Corvette ZR1, boost is handled by an HKS electronic controller, Synapse blow-off valve and wastegate, with the exhaust pumped through a custom 3-inch Magnaflow exhaust. All of the tubing and tuning for the system was done in-house by DDMWorks.

DDMWorks says 375 of those 430 horsepower make it to the wheels, delivering what can surely only be analogized to rocket-like performance.
