Overview

The Tuners Choice

The SF-880E AWD chassis dyno was built for serious automotive performance tuners who want unmatched quality, capacity and data acquisition.

Electric Wheelbase Adjustment

The SF-880E dyno has electric push-button wheelbase adjustment to accommodate wheelbases from 88 to 134 inches. This allows vehicles to be placed in the proper location on the rolls for maximum traction every time. The SF-880E accommodates track widths from 40 to 84 inches and has an equivalent vehicle inertia of 3,467 lbs. Other models in the SF-800 series offer longer wheelbases, wider track widths, and different inertias.

200 MPH Mechanical Roll Synchronization

The SF-880E chassis dyno includes all-wheel drive speed synchronization with a simple and reliable driveshaft connection between the front and rear rolls. This eliminates the chance of damaging center differentials and activating traction or stability control systems on the dyno. This driveshaft speed synchronization system is unique to SuperFlow® and the only one available that doesn’t have to be disconnected to test above 175 mph. SuperFlow speed synchronization is always engaged and available all the way up to 200 mph.

Unmatched Accuracy Through Engineering

Trunnion mounted differentials are equipped with individual torque cells to measure torque produced at each axle. This system also makes SuperFlow AWD chassis dynos extremely accurate because any variance in dyno components like bearings and differentials are compensated for as the measurement is made.

Superior Eddy Current Load Capacity

Two eddy-current power absorbers are mounted to the differential between the rolls to provide more load capacity across the entire operating range. Mounting the power absorbers to the differential provides two major advantages over other systems:

  • It spins the power absorbers at 2.5 times roll speed meaning the SF-880E will provide significantly more load capacity starting at 0 mph than other dynos – this gives you more load to tune at the speeds vehicles are actually operated. We’re so confident in this design we publish our load curves across the entire operating range rather than only publishing peak load which is only available at the top speed of the dyno.
  • It keeps the power absorbers cooler by increasing their airflow giving you more load for longer durations

Standard and Custom Test Profiles

  • Inertia tests: fast, accurate and extremely repeatable
  • Controlled acceleration tests: sweep test at user-defined acceleration rate provides a consistent load to simulate actual acceleration rates a vehicle will see in operation
  • Step testing: step through set RPM or MPH points at either wide open or partial throttle for quick and easy fuel mapping
  • Steady state: manually control the RPM or MPH for fuel and ignition timing mapping
  • Engine power test: coast down to quantify drivetrain losses and derive engine power
  • Drive cycle – user-defined drive cycles like US06, FTP75, etc. It can be outfitted with an AC motor for full inertia simulation

More Traction and More Accurate

42-inch diameter, precision knurled rolls provide a massive contact patch for superior traction and minimal tire deflection. Systems with very small rolls or worse, cradle rolls, cause excessive tire deflection creating dangerous amounts of heat in the tire and increasing the risk of tire failure. Any heat in the tire is also power that was not measured by the dyno adding to the inaccuracies of small roll dynos.  Additionally, small rolls have such small tire to roll contact they require strapping the vehicle in a downward fashion to make traction – this increases tire deflection and eliminates the suspension, greatly increasing the shock load to the drivetrain while testing. The large rolls in the SF-880E allow for straps to be positioned more linearly with the goal of holding the car on the dyno, not creating unnatural amounts of downforce reducing stress to the driveline and heat in the tires.

Multiple Models for the Perfect Fit

SuperFlow’s SF-800 series all-wheel-drive chassis dynamometers are the most complete and feature-rich AWD chassis dynos on the market. Various models in the 800 series let you select the model with the proper wheelbase, track width and equivalent vehicle inertia for your application. Like any SuperFlow dynamometer, they are designed to be more accurate, more repeatable and more durable than anything else available. Call us today to discuss your application.
