System Performance The combination of the TVS2 technologies has resulted in a significantly improved thermal efficiency map. The TVS2, Figure 36, thermal efficiency in both the steady state and transient operating regions has increased significantly compared to the TVS R410 supercharger, Figure 37, where peak thermal efficiency is achieved in the core of the steady state operating region. The maximum transient operating speed of the TVS2 unit, highlighted in Figure 37, has been increased from 24
