DDMWorks Ariel Atom – Click above for image gallery

Because the Ariel Atom simply isn't mental enough and there simply isn't enough crazy in the world, South Carolina-based tuners DDMWorks had to go and twin-charge it: a Borg-Warner turbo mated to a Harrop supercharger. An Atom weighs 1,375 from the factory, and with over 300 horsepower on tap, it's 4.6-pounds-per-horse allows the standard Atom to hit 60 miles per hour from a standstill in less than three seconds. Obviously, that's not enough...

So throw the instant-reaction combo of a supercharger and a turbocharger, and you've got 375 hp to play with and just 3.4-pounds-per-horse. If they do any more, it'll be faster than your reflexes. You can read about DDM's work in the presser after the jump, and check out the atomic Atom in the gallery of photos below.

430HP DDMWorks Twin-charged Ariel Atom Provides Incredible Power to Weight in a Small Package.

Piedmont, SC January 22nd, 2010 – The introduction of the DDMWorks Twin-charged kit for the Ariel Atom provides a powerful setup combining the best attributes of turbocharging and supercharging for one of the most fun cars on the road. Power to weight ratio is the name of the game here, and the twin-charged Atom has only 3.4 lbs per horsepower, a better power to weight ratio than a Bugatti Veyron or an Enzo Ferrari.

With the unique combination of both a supercharger and a turbocharger you get power on tap from the moment you touch
the throttle and that power keeps going all the way to redline. The Twin-charge kit is carefully tuned to deliver maximum
horsepower, while also keeping drivability and engine safety in mind. This combination of power, drivability and safety makes the DDMWorks Twin-Charged Kit unlike any other power adder on the market for the Ariel Atom.

The boost for the Twin-charged kit for the 2.0L LSJ ECOtec is accomplished with a Borg-Warner S256 Turbocharger working together with a Harrop HTV1320-LSJ. The Harrop HTV1320 supercharger uses Eaton's TVS (Twin Vortices Series) highly efficient rotor assemblies. This TVS technology is also used on the new Corvette ZR1 supercharger, and dramatically increases the efficiency of the supercharger. Boost control for the entire system is handled by a HKS electronic boost controller, Synapse blow off valve and wastegate. All the exhaust exits through a custom made 3" magnaflow exhaust. Tubing, manifolds and tuning for making the entire system work together is done in house by DDMWorks.

Power output is raised substantially from 230hp in the stock Ariel Atom to 375HP+ at the wheels, a gain of 145HP. Base price for the twin-charged Ariel Atom upgrade starts at $6,500 USD installed with the TVS based systems and larger gains available with other options and configurations. The Twin-charged Ariel Atom upgrade is currently available with installation and tuning done onsite at our facility in South Carolina.

      Any more power and this thing will go back to the future.

      What purpose does it serve? All the extra horsepower is going to give you is a higher top speed, provided the gear box and ratios will allow for it to go that high without hitting the rev limiter.

      The normal Ariel Atom is already capable of hitting 0 - 60 in 2.8 - 2.9 seconds at the fastest, which is almost as fast as you can possibly accelerate a car due to the coefficient of drag.

      I guess I am just missing the point.

        ever heard of a veyron??
        • 5 Years Ago
        the point is.... When you first drive the Atom it's a amazing, exhilarating, unforgettable drive. Its more acceleration that you've ever felt combined with wind and screaming superchargers and bugs in your face. It's a sensory overload but your somehow in control of it (just barely).

        Then you drive the car for a few years and you track it. It becomes very comfortable and predictable. After a while 230 hp seemed to slow.

        So I turbocharged to about the same horsepower and I'm back to the car scaring the crap out of me again. I'm sure in a few more years I'll need a couple more hundred horsepower again.

        The point is its an addiction. :)

      FWIW, I know Dave of DDMworks and he is a GREAT guy. He's worked on a few miatas that I've either owned or driven, and I've seen a couple of Saturn Sky's that have parts from his cars on them.

      I would encourage anyone who's considering parts/service from DDMworks to go through with it. Dave WILL take care of you and while he's not the cheapest guy in the business, the level of service you receive will far outweigh any cost savings you may find with another vendor. The parts he offers are made of quality components and fit without a bunch of cussing and custom-fitting.

      Disclaimer: I have no business connection with Dave or DDMworks other than being a satisfied customer.

      I call for an SDR WR3 challenge.

      The Subaru STI 2.5 liter flat four can beat 375 rear wheel horsepower with only a properly tuned upgraded turbo.

      the clash of the tube-chassis titans! :D
      • 5 Years Ago
      375? Don't care. There are faster, more entertaining, and more powerful atoms out there. I'll take mine with 400+ hp and a 'busa V8 that revs to the heavens. Everything else is just childsplay.
        • 5 Years Ago
        @ngiotta - why? the prototype's for sale for tons less than ariel want's to charge. Had I the money, I'd own it right now.
        • 5 Years Ago
        Hartley H1 V8 FTW.

        I can't wait until the upcoming BMW touring motorcycle brings an inline 6 back to motorcycling... The engine that the BMW Concept 6 motorcycle showed a few months ago.

        And then someone uses that ultra compact and light weight engine to create a V12, or better yet, a flat 12.

        then, put THAT in a light weight sports car with a double clutch gearbox...

      point = ?

      A supercharger and a turbo and all they can cobble up is an additional 75hp? I feel like one or the other would be sufficient to add 75hp.

      Still... that has to be mind-alteringly fast.
        • 5 Years Ago
        It's on a 2.0L ecotec, so you're still limited a bit by displacement. That being said, the quoted article text also says the stock power output is 230hp, making 375 whp put out by the twincharged ecotec a net gain of 145hp.
        • 5 Years Ago
        The press release actually says it adds 145 HP, not 75 HP, for a max of "430 HP" ... which I'm not sure how they come to. But whatever.
        • 5 Years Ago
        There are different power figures being quoted. It looks like the stock car makes 300hp at the crank, 240 at the wheels, while the modded car makes 430hp at the crank and 375+ at the wheels.
      • 5 Years Ago
      At some point these cars do not need more HP. Their beauty is in their light weight and good HP. Where that HP limit is however is the question.
      • 5 Years Ago
      I NEED THAT!!!!! what would happen it they did this to the V-8 version coming out? 6.5 grand isn't bad but how much does it cost to get one here state side?
