AutoDyn 11 Chassis Dyno
600+ hp (447kW) and 150 mph (241 kph)

SuperFlow's AutoDyn 11 is a compact cradle-roll chassis dynamometer with an eddy current power absorption unit. The cradle-roll design makes it easy to load and unload vehicles. The AutoDyn 11 fits in shallow pits or above ground with a ramp kit. It is very affordable and yet has all the data acquisition and control power of SuperFlow's premium models.

The AutoDyn 11 allows you to test vehicles with over 1,100 horsepower at speeds up to 150 mph. Its standard power absorption unit holds up to 750 hp at the tire patch. The AutoDyn 11's rolls are only 23" (58 cm) apart so you can test narrow-track drag race vehicles.

Its 7,700 lbs (3500 kg) per axle test capacity and generous 97" outer roll width allow you to test large vehicles. Its durable construction, 10-year bearings and first rate customer service department help make the AutoDyn 11 a low-cost, long term investment.

Above Ground Ramp Kit
SuperFlow offers lightweight aluminum ramp kits for the AutoDyn 11 and AutoDyn 30 chassis dynos. Kits include heavy-duty aluminum ramps and extended platforms that support the vehicle during testing. Because they are light-weight these ramps work great for portable dyno applications and they are easy to move in and out of place.

Ramps are perfect if you are unable to install your SuperFlow chassis dyno in a pit or when shop space is limited because they stack neatly out of the way when not in use. Contact a SuperFlow Sales Engineer today to get the correct ramp kit for your chassis dynamometer.

4-post Hoists
SuperFlow offers several different 4-post hoists to fit any needs and budget. Models are available with a walking platform, safety rails and access ladders to make working on vehicles easy and safe. SuperFlow also offers an economy hoist that does not include the extra features listed above, but still works great for loading vehicles on and off your chassis dyno quickly and easily.

All lifts come with tie-down anchor points at the front and rear of the platform to secure vehicles for testing. 4-post hoists let you make performance upgrades anywhere on the vehicle without having to move it from the dyno. Additional benefits include oil changes, performance upgrades, brakes, tire rotations, etc.

Contact a SuperFlow Sales Engineer today to learn more about 4-post hoists as well as other options for above ground installation of your SuperFlow chassis dyno.

AutoDyn Tie Down Strap Kit
Standard tie-down strap kits include (4), 2in. by 15ft. heavy duty straps with ratchets and (2), 2in. by 4ft. web-sling straps with eyelet to eyelet ends. Cored in-floor anchors are available separately.

In-Floor Anchors
In-Floor AnchorsSuperFlow offers in-floor, compression style anchors to outfit your shop with convenient, yet out of the way tie down points. The 3.5in. anchors feature a chain receiver that allows you to quickly attach the tie down chain or remove it when not in use. The anchors have a 10,000 lb. (4,536kg) horizontal rating and a 500 lb. (227 kg) vertical rating. A cover plate is included to fill the receiver hole when the anchors are not being used.

*Chain is not included because each installation varies

Optical Wheel Tachometer
SuperFlow’s optical wheel tachometer reads wheel speed using an infrared beam and reflective tape. It features a magnetic base for secure mounting to any AutoDyn frame. The optical tach is non-contact and works in many applications where inductive pickups may not. Contact a SuperFlow Sales Engineer today for more information on all of the options available for SuperFlow chassis dynamometers.

Inductive Spark Pick-Up Assembly
SuperFlow’s Inductive Spark Pick-Up Assembly features a rugged housing that protects the device from tough shop environments and allows it to provide years of service. With user-adjustable sensitivity you’re able to dial in the device exactly how you want it.

The spark pick-up includes one inductive clip. For wasted spark ignition systems a second clip can be added. Contact SuperFlow today for more information on this and other options to get the most out of your SuperFlow chassis dyno.
