Pity you can’t see the two rev counters (compressor and power turbines) in the Howmet clearly in the on-board. The gauges go to 50k rpm on the first scale, then from 50k to 100k on the second revolution of the needles! Fascinating to watch. Drive is controlled by a wastegate between the two turbines- no mechanical connection, and no gearbox- except for reduction gearing, obviously!
Last couple of pics. Nice Supra and a box of touring cars....
