I apologize. I confused this video with the September 15, 2012 video. In that video, it was mentioned that you were installing the Wolfsburg West Okrasa modification for the first time and that, further, you heard reports that the engine was producing over 50 horsepower. This agrees with the April, 1957 edition of Hot Rod magazine where the graph shows that the engine made about 48-49 horsepower without the Abarth exhaust.
I was just curious about the driving experience, whether it was very effective or mild so. The Hot Rod magazine article says that the bug's passing ability was greatly improved.
My engine is at Jansen Enterprises here in California and I'm having him install the Wolfsburg West induction system, a stroked crank, and Abarth exhaust. I'm pretty certain these changes will add much power without, hopefully, wrecking it's classic look.
