Yeah I remember those, it was a Granatelli car?
I as a kid remember reading a book about a mechanic who built a turbine car for the Indy, it was so fast they limited him on tire size, so he redesigns the tire compound. From the 70’s era.
Yup...Andy Granatelli...STP..The Greatest Spectacle in Racing...dang I’m old...you must be too, LOL!
