I saw a match race with a car equipped with one of these at the old Lyons Dragstrip back in the early 70’s.
As the article said, too much wheel spin to be practical for the time.
Impressive as hell to watch however.

Lyons Drag Strip? Was that the one in Long Beach, just off Wardlow I think it was ? Grew up real close to there.
