The blokes working on it told me that the voltages that the motor see's from the controller have to be reduced at very low revs, they were keen to use as large a rev range as they could, to the limit of their electronics. I should have asked a few more questions. A wheel turns about 500 rpm for 100 Kph, so with a 3:1 diff your still looking at only 1500 revs at the speed limit. They were thinking of leaving it in second. Pete I have to put my hand up and admit that I tainted the purity of my beloved ford XY with a Turbo 400. The car finally felt the cruel hand of defeat by a Mazda station-wagon with a turbo'ed nitrous'ed ported 13B rotary motor. Smashed me by almost a second. A flamin shopping trolly! The lock up friction clutch in the torque converter is most times just a flat disc that hydraulically presses against the front plate. They are a bit fragile and don't handle a lot of power. I have noticed often the car's owner has no idea it has stopped working. I'm confused, no wait... maybe I'm not...
