There was indeed a catastrophic incident at Bonneville in the 1960s..... It involved the use of oxygen injection..... as I had been told, anyway... a racing legend, Bob Herda, lost his life....
And yes, how about those turbonique units?.... as fas as I also recall, Turbonique also marketed a little turbine engine that also ran a centrifugal supercharger. It looked like a turbo charger.... more or less, anyway.... and could produce some impressive horsepower numbers.... it was these items that prompted NHRA and other sanctioning organizations to specify that the supercharger must be mechanically or exhaust driven.
GM diesels huh?.... the earlier reference sounds like something that I would have bought at least two of!!!!
