One of the primary reasons we selected the engineering grade Superflow AWD-30 chassis dyno was the system's mechanically driveshaft coupled front and rear rollsets. This is one of the most advanced and accurate chassis dynamometers on the market. The mechanically linked rollsets allow advanced all wheel drive vehicles like the 2017 NSX to be tested as if it were on a road.
We had our first opportunity to baseline a 2017 Acura NSX at our Chandler, AZ facility at our recent open house meet. Thank you to local customer Kevin L. in allowing us to use his fully loaded 130R White 2017 NSX for testing. Dyno plot showing horsepower and torque (both SAE corrected) at the wheels, as well as manifold (boost) pressure, and AFR. The first most striking difference compared to a conventional gasoline engine is the enormous torque generated at low engine speeds due to the electrically assisted powertrain. The second point of interest is seeing how the turbochargers (which are electrically controlled) are limited to achieving peak pressure until 6000 RPM. Perhaps this is due to concerns of drivetrain reliability or the "smoothness" of the power delivery as the electric motor assist tapers off. The last point of reference is the power number, which is 415 - an average of the multiple test runs completed. The factory car is rated at 575 BHP total net system power. The car was tested in 4th gear - and it is conceivable that the electric motors are decoupled at certain wheel speeds (the car at rev-limiter in 4th gear is traveling nearly 120 MPH) for reliability. Perhaps lower gears would have maintained electrical assist allowing a greater peak horsepower number.
At the moment, we are already in development on cosmetic, exhaust system, and suspension upgrades for the 2017 NSX. We are also in early stages of exciting ECU tuning capability. We look forward to applying our 15 years of experience to this new platform!
