There were hop-up parts for Opel cars back in the late 1960s. A buddy owned a Kadett with a 1.1 liter 4 banger that would turn 7,000 rpm.
It sounded like a thousand angry bees...

I had an Opel record (~ 1960) that looked like this less the chrome. It was sort of salmon colored.

I drove it to school ai Raleigh across the mountain through Boone. It would barely make it up the mountain. By the time I got to the top it was making only about 35. It ran good on the flat though.

On one trip coming out of N Wilkesboro on a long down hill, the hood latch gave way and the hood wrapped back over the windshield. It took a while to realize what had happened and I finally got it off the road with my head out the window.
